1. GLEESON CJ. The principal facts, the nature of the proceedings, and the relevant legislative provisions, appear from the reasons for judgment of Gummow and Hayne JJ ("the joint judgment").
2. In December 1996, Mr Ryan consumed oysters that a relative had purchased from the companies described in the joint judgment as the Barclay companies. The oysters, which had been grown in Wallis Lake, near Forster, were contaminated. In consequence, Mr Ryan contracted the hepatitis A virus ("HAV"). The circumstances of the contamination are explained in the joint judgment. Heavy rainfall over a period in November 1996 had increased the risk of pollution of the lake from a number of sources, and had resulted in cessation of harvesting for four days. In February 1997, an HAV epidemic was notified, and on 14 February 1997 Wallis Lake growers ceased harvesting for the season.
3. In seeking to assign legal responsibility for the harm he suffered, Mr Ryan blamed the growers and distributors of the oysters (the Barclay companies), the Great Lakes Council ("the Council"), which was the local government authority that exercised regulatory functions, including functions designed to protect the environment, under the Local Government Act 1993 (NSW) ("the Local Government Act"), and the State of New South Wales ("the State"). Claims were also made under the Trade Practices Act 1974 (Cth) ("the Trade Practices Act") against the Barclay companies. That is how the case came to be litigated in the Federal Court. The Trade Practices Act claims were not directly in contest in this Court.
4. In the present appeals, the principal issue in relation to the claims against the Council and the State was whether there was a duty of care of such a nature that any act or omission shown to have been causally related to Mr Ryan's injury constituted a breach. In relation to the claims in tort against the Barclay companies, the existence of a duty of care was accepted; the principal issue was whether a breach had been established.
5. It is convenient to deal with the claims against the various defendants in the following sequence: the State; the Council; the growers and distributors. There are important differences between claims made against the State and the Council, on the one hand, and those made against the Barclay companies, on the other. A consumer of food suffered personal injury because the food was unfit for human consumption. His case against the growers and distributors of the oysters is essentially a straightforward product liability case. He sued the producers and suppliers of the product, the form of contamination being such that it was not reasonably discoverable upon any intermediate inspection. The existence and content of a duty of care was not in contest. But the nature of the case against the other defendants is far less obvious. The consumer is suing the government; local and State. He seeks to make the government directly liable. Originally there were attempts to establish tortious conduct on the part of persons, authorities or instrumentalities, for whom, or for which, the State might be vicariously responsible, but those attempts failed on the facts, and have not been pursued in this Court. The allegations now pressed against the State, and the Council, do not involve allegations of carelessness in the exercise of a statutory power. The complaint is not about acts, but about omissions. In the particular circumstances of the case, the issues, raised by this assertion of direct governmental liability in negligence, include what are, in the final analysis, issues of justiciability.

1. What was formerly a Crown immunity from tortious liability disappeared early in the history of New South Wales. Procedures for suing a nominal defendant on behalf of the government were first introduced in 1857[6]. The Claims against the Government and Crown Suits Act 1912 (NSW) provided in s 4:

"The petitioner may sue such nominal defendant at law or in equity in any competent court, and every such case shall be commenced in the same way, and the proceedings and rights of parties therein shall as nearly as possible be the same, and judgment and costs shall follow or may be awarded on either side as in an ordinary case between subject and subject."

1. The Crown Proceedings Act 1988 (NSW) abolished the nominal defendant procedure but, in s 5, adhered to the formula that proceedings and rights should be as nearly as possible the same as in an ordinary case between subject and subject[7]. That formula reflects an aspiration to equality before the law, embracing governments and citizens, and also a recognition that perfect equality is not attainable. Although the first principle is that the tortious liability of governments is, as completely as possible[8], assimilated to that of citizens, there are limits to the extent to which that is possible. They arise from the nature and responsibilities of governments. In determining the existence and content of a duty of care, there are differences between the concerns and obligations of governments, and those of citizens. Such differences led to an attempt to distinguish between matters of policy and operational matters. That distinction was never rigorous, and its validity and utility have been questioned[9]. Even so, the idea behind it remains relevant in some cases, such as the present. In Sutherland Shire Council v Heyman[10], Mason J said:

"The distinction between policy and operational factors is not easy to formulate, but the dividing line between them will be observed if we recognise that a public authority is under no duty of care in relation to decisions which involve or are dictated by financial, economic, social or political factors or constraints. Thus budgetary allocations and the constraints which they entail in terms of allocation of resources cannot be made the subject of a duty of care. But it may be otherwise when the courts are called upon to apply a standard of care to action or inaction that is merely the product of administrative direction, expert or professional opinion, technical standards or general standards of reasonableness."

1. One of the reasons why matters of the first kind are inappropriate as subjects of curial judgment about reasonableness is that they involve competing public interests in circumstances where, as Lord Diplock put it, "there is no criterion by which a court can assess where the balance lies between the weight to be given to one interest and that to be given to another"[11].
2. There are forms of governmental activity, which courts in the past endeavoured to describe by the term "operational", where there is no reason for hesitating to assimilate the position of governments to that of citizens in imposing duties and standards of care. Such activity might involve budgetary considerations, but that does not prevent such assimilation. Individuals and corporations also have to watch their budgets, and decisions about what is reasonable may have to take account of that. As the other extreme, the reasonableness of legislative or quasi-legislative activity is generally non-justiciable.
3. Here we are concerned with the problem of deciding, in a case where the government had certain powers, whether it is accountable, through the law of negligence, for not exercising its powers, or for not exercising them sufficiently. To apply that form of legal accountability requires the identification, not merely of a power, but also a duty; a duty of care owed to a citizen or a class of citizens. A conclusion that such a duty of care exists necessarily implies that the reasonableness or unreasonableness of the inaction of which complaint is made is a legitimate subject for curial decision. Such legitimacy involves questions of practicality and of appropriateness. There will be no duty of care to which a government is subject if, in a given case, there is no criterion by reference to which a court can determine the reasonableness of its conduct. That negative proposition leaves open other questions as to the circumstances in which the law will treat failure on the part of a public authority to exercise a power as a breach of a private law duty of care; but it is sufficient to resolve a substantial part of the case against the State in these proceedings.
4. In the Federal Court, at first instance, Wilcox J described the primary case against the State as being that it failed to prepare or implement any proper oyster management plan for Wallis Lake. It had no statutory duty to take such action, but there were various powers available to it upon which it could have relied if it had decided to do so. Wilcox J also referred to arguments that sought to make the State responsible for alleged failures on the part of the Environmental Protection Authority and the Health Department. Those arguments were rejected on the facts, and it is unnecessary to say more about them. As to the primary case, it is to be noted that it was expressed in terms of breach. The formulation of the breach implies a legal duty, owed by the New South Wales government to Mr Ryan and all consumers of oysters grown in Wallis Lake, to "prepare and implement [a] proper oyster management plan". That case was later narrowed by reference to certain aspects of management. There was a separate argument that, given the deficiencies of the state of management as at November 1996, the State should have exercised a power to close the fishery. That argument occupied more familiar territory, pointing to a specific statutory power, conferred for a purpose, and asserting a duty to exercise the power in the circumstances[12].

"(a) the State owned, and had powers of control over, the lake;

(b) through the Department of Fisheries, it established, and supervised the operations of, a mosaic of oyster leases;

(c) through the Department of Fisheries, it issued, and enforced the provisions of, aquaculture permits;

(d) through the Department of Health, the State supervised the depuration process, including the nature and location of water intake points and the design, construction and maintenance of depuration tanks and ultra-violet facilities;

(e) through the EPA, the State had powers under the Clean Waters Act to remove, disperse, destroy or mitigate pollution of waters (s 27) and to carry out inspections and investigations of premises (s 29);

(f) through a number of agencies, the State was a participant in the Wallis Lake Estuary Management Committee, one of whose objectives was to prepare a management plan designed 'to sustain a healthy, productive and attractive estuary'; and, most importantly,

(g) through the Minister for Fisheries, it had the power - at any time, to prohibit the taking of oysters from the lake."

1. It has already been noted that Wilcox J did not find the government departments and authorities mentioned guilty of tortious conduct for which the State was vicariously responsible. In order to understand the legal implications of various aspects of governmental control, it is necessary to examine the legislative and regulatory structure set up by the State Parliament, and the executive. This appears in the joint judgment. A statement that the State had managerial control over the oyster industry involves a degree of ambiguity. The State, the body politic, was the government. Its legislature had all the powers given to it by its Constitution, subject to the Commonwealth Constitution. Its executive had powers given by the legislature. But Mr Ryan seeks to make out a case based on non-feasance. What is the basis for saying that the State owed a legal duty to the consumers of Wallis Lake oysters to exercise to a greater extent governmental powers of regulation over, or affecting, the conduct of producers and distributors of oysters? Why could not the State have relied on self-regulation by the industry itself? The assumption that a State government owes to individual citizens a legal duty to care for the health and safety of all citizens, or all consumers of food, or all consumers of oysters, by exercising its regulatory powers to the extent judged reasonable by a court, has far-reaching implications.
2. It emerged from the evidence that, for some years before 1996, there had been, within government and industry circles in New South Wales, a continuing debate about the appropriate boundaries between government regulation and industry self-regulation.

1. In April 1992, an Advisory Committee drafted for the Minister for Health Services Management a report entitled "New South Wales Oyster Quality Assurance Program". It supported a large measure of industry self-regulation, with government involvement. It included the following:

"… inherent in the move towards industry self regulation is a consideration of the role of government agencies, particularly the NSW Health Department because the Minister for Health is charged with a responsibility for protecting the public's health and has appropriate regulations under the Food Act to ensure that foods which reach the consumer are indeed fit for consumption. In short, irrespective of any industry endeavours it is the NSW Health Department that makes the final judgement about the product and has the powers to impose penalties.

… if the industry can achieve via self regulation a situation whereby its product meets the desired standards and offers a high degree of assurance to the public then the active role of government must be greatly reduced with consequent savings to the public purse.

It is hoped that government will recognise this and respond accordingly by fostering the quality assurance objective.

In the Advisory Committee's view, non-participants however few or many they may be, negate the whole concept of a quality control program and will almost certainly compromise its integrity at some stage.

It is recommended therefore that the government amends purification plant permit conditions so that all oysters treated in plants be cultivated, harvested and purified in accordance with an approved quality assurance program.

As an incentive for industry to meet the costs of quality assurance programs, oysters produced under a quality assurance program could be appropriately endorsed.

The endorsement is made through the quality assurance program and not the NSW Health Department, enhancing industry self-regulation and quality assurance program integrity."

1. In February 1994 a report to the Minister recorded:

"The NSW Oyster Quality Assurance Program is based on a concept of industry self-regulation at the estuary level, with a minimum of central supervision."

1. An Advisory Committee made further recommendations as to the detail of a Quality Assurance Program. A Ministerial paper to Cabinet in November 1994 stated:

"4.14 The QAP is to be industry run and industry funded. Funding for the program is required at three levels:

(i) to pay for meat testing prior to marketing the oysters - this is required now and, as now, will be funded by the individual oyster farmer;

(ii) to pay for the environmental testing required by, and any other costs associated with, the estuary-based program - it is proposed that these funds will be collected at the local level by the local committee responsible for developing and implementing the program;

(iii) to pay for statewide co-ordination of the estuary based programs and other costs associated with the QAP - it is proposed that this requirement would be met through an 'annual contribution' required from all oyster farmers by Regulation made under Section 156 of the Fisheries Management Act 1994."

1. Other evidence to like effect is set out in the reasons of Lindgren J. It demonstrates that the nature and extent of State government involvement in oyster quality control was a matter of policy, that it received attention at the highest levels, that it had substantial budgetary implications, and that it involved government concern to encourage an important primary industry.
2. This demonstrates two things. First, the proposition that the State government had substantial managerial control over the oyster industry is, at best, an over-simplification. Secondly, the proposition that the State had a legal duty of care, owed to oyster consumers, obliging it to exercise greater control (and, presumably, to permit less industry self-regulation) takes the debate into the area of political judgment. By what criterion can a court determine the reasonableness of a government's decision to allow an industry a substantial measure of self-regulation?
3. This is not a case where past experience, in New South Wales or elsewhere, had demonstrated the inadequacy of a quality assurance program to which the State was a party. It was, of course, known that there were risks to consumers, which was why there was a need for a quality assurance program in the first place. But such knowledge does not warrant a conclusion that the State, as a body politic, directly owed a legal duty to consumers to increase the level of regulation of the industry, or to exercise, to a greater extent, the powers of control available to it.
4. However, there is one respect in which there was said to have been a negligent failure to exercise a specific power.
5. The Fisheries Management Act 1994 (NSW), by s 189, empowered the Minister to impose a prohibition, called a fishing closure, in relation to the taking of fish under an aquaculture permit if satisfied that the area was in such a condition that the taking of fish ought to be suspended, or that the fish were, or were likely to be, unfit for human consumption. The power was conditioned upon the existence of a certain state of satisfaction. No such state of satisfaction existed at any time relevant to the present proceedings. The Minister cannot have been under a legal duty to impose a fishing closure for the reason that, in the state of affairs that existed, he had no power to do so.
6. Kiefel J considered that, if the Minister had been properly informed, the rainfall in November 1996 must have given him reason to be concerned about the fitness for human consumption of Wallis Lake oysters. She said that "the State thereby came under a duty to exercise its powers and prohibit harvesting until the Minister could be assured of the likelihood of the oysters' fitness for consumption".

1. Part of the basis of the holding in the Federal Court of a duty of care on the part of the State was what was said to be its managerial control over the oyster industry. No such control existed in the Council. However, a different form of control was said to be relevant: powers of control over the activities that constituted potential sources of pollution of Wallis Lake. From those powers, conferred in the main by the Local Government Act, coupled with foreseeability of harm, it was argued that there was a duty on the part of the Council to eliminate or reduce the risk of viral contamination of Wallis Lake; a duty owed to consumers of oysters grown in the lake and, presumably, all others (such as swimmers) who might suffer physical harm in consequence of such contamination.
2. The content of the duty, thus asserted, raises difficulties. A legal duty to eliminate the risk of viral contamination of the waters of the lake seems far-fetched. The evidence showed that such a risk could never have been eliminated. Wilcox J did not accept that there was such a duty. But, if the duty were merely to reduce, or take reasonable steps to reduce, pollution of the lake, the problem of causation earlier mentioned arises. Who is to say that risk reduction would have spared Mr Ryan from illness? That question, in turn, points up the remoteness of the powers of control available to the Council from the cause of harm to Mr Ryan, that is to say, the consumption of oysters produced and distributed by the Barclay companies[15]. Furthermore, the same problem affects the case against the Council as affected the case against the State: the circumstance that, in the public interest, certain powers of regulation of activity within its area are vested by statute in the Council does not mean that the Council owes a legal duty to individuals or classes of person whose health may be affected, directly or indirectly, by decisions made as to the exercise of those powers.
3. In the Full Court, Lindgren and Kiefel JJ both concluded that the Council was not subject to a duty of care of the kind alleged. I agree with that conclusion.
4. The starting point for consideration is the statutory provisions conferring on the Council its relevant functions and powers. These provisions are set out in the joint judgment.
5. In considering the powers and responsibilities of the Council, for the purpose of determining whether it owed a duty of care to oyster consumers, an aspect of the facts should be noted. Wallis Lake is large, and there were many different ways in which, and places at which, human activity on or around the lake could result in pollution of its waters. There was no particular place of pollution that was shown to be responsible, or mainly responsible, for contamination of the oysters. As Lindgren J pointed out, assertions of a duty to reduce or minimise pollution are difficult to give practical content of relevance to the harm suffered by Mr Ryan. As with the State, the complaint is that the Council did not do enough to reduce pollution, but it is not possible to point to any specific act or omission that would have prevented harm to Mr Ryan[16].

1. The duty of care upon which the case against the Council was based was not made out.

1. Here, the issue is one not of duty, but of breach.
2. Wilcox J said:

"The Barclay companies acknowledge they owed a duty of care to consumers of their oysters. They deny they breached that duty and assert that, if they did, this did not cause the HAV infection suffered by [Mr Ryan] and relevant group members."

1. There was mention, in the course of argument in this Court, of the possible significance of the Trade Practices Act, and the causes of action it creates, upon the existence of a common law duty of care in the Barclay companies. That is an interesting topic, but in the light of the concession noted above, and the manner in which the case was argued, both in the Federal Court and in this Court, the present is not the occasion to pursue it.
2. Although counsel for Mr Ryan argued that the Barclay companies were negligent in the decisions they made in November 1996 as to when to cease and when to re-commence harvesting, Wilcox J did not accept that there was any causal connection between that conduct and the HAV epidemic. Wilcox J noted that it was accepted that Mr Barclay was at all material times aware of the existence of potential sources of viral pollution to the lake, and he knew that depuration was not adequate to remove viruses, and that oyster meat testing would not necessarily show viruses. Wilcox J summarised the negligence of the Barclay companies in the following sentence:

"In my opinion, in selling without warning oysters grown in waters known to be subject to possible undetectable viral contamination, both Barclay companies breached their duty of care to ultimate consumers of the oysters."

1. It is not clear what the words "without warning" add to that finding. It is hard to imagine that Wilcox J contemplated that the oysters might have been sold with a warning. Jonathan Swift wrote: "He was a bold man that first eat an oyster"[19]. It would be a bold fish merchant that displayed oysters for sale accompanied by a warning that they might be subject to undetectable viral contamination. The negligence found was in selling the oysters in the prevailing circumstances as known to the Barclay companies. The corollary is that they should have stopped selling Wallis Lake oysters until such time as improved quality assurance procedures made it reasonable to re-commence.
2. In the Full Court, Kiefel J decided the case on the basis "that even if the harvesting of oysters had not been prohibited in the circumstances prevailing, as it should have been, the Barclays companies should not have supplied oysters for sale until a sufficient period had elapsed by which the risk of contamination could be regarded as acceptable or tests sufficiently indicated that to be the case". Lee J agreed with Kiefel J.
3. Lindgren J was of a different view. He said:

"Having regard to the fact that it is not possible anywhere where human beings are to guarantee that purity of the water, it seems to me that the critical question in the present case is whether, as a result of what Mr Barclay knew or should have known about the quality of the water in the Lake, the Barclay companies' duty of care required them to do more than simply to suspend harvesting following a 'fresh', to depurate in accordance with Mr Bird's booklet and to test the flesh of sample oysters before and after depuration.

So far as Mr Barclay in fact knew, subject to the necessity of ceasing harvesting following a 'fresh', the water of the Lake was safe water in which to grow oysters. The Lake's oysters had never previously given rise to an outbreak of hepatitis A or of any other oyster-related disease, although no doubt there had previously been rainfall events similar to that of 23-25 November 1996. Mr Barclay testified that over the four year period from 1989 to 1993, he had regularly taken the Council's Mr Brooker out in his boat to test the water in the Lake at twelve locations and that the results were satisfactory. He said that in the 'paddock' where virtually all Barclay Oysters' harvesting was done, the results were always excellent. Apparently, depuration and suspension of harvesting following a 'fresh' had proved sufficient measures for the Lake's oyster growers to take in the past.

Depuration, suspension of harvesting and flesh testing cannot guarantee that an oyster is safe to eat. As his Honour observed, the starting point was to attack faecal contamination of the Lake at source. Whether it was reasonable for the Barclay companies to involve themselves in that activity requires

'a consideration of the magnitude of the risk and the degree of the probability of its occurrence along with the expense, difficulty, and inconvenience of taking alleviating action …' (Wyong Shire Council v Shirt...[20]).

His Honour thought that their duty of care required the Barclay companies to conduct their own sanitary survey of that part of the shoreline of the Lake, the rivers and islands that was publicly accessible, then attempt to procure governmental or local governmental involvement to ensure that any faecal contamination revealed by the survey was rectified.

But, with respect, his Honour did not consider the matters referred to in the passage from Wyong Shire Council v Shirt set out above from the viewpoint of the Barclay companies. Other particular questions arise. What about the future, would the Barclay companies be obliged to update their sanitary survey frequently and regularly? At what point, if any, would they become entitled to assume that the issue of faecal contamination of the Lake could be left to the authorities? If it is accepted that they would become entitled to make that assumption at some time, why was Mr Barclay not entitled to make it in November 1996?

His Honour had regard to the difficulty that there was no assurance that the authorities would act, saying that if they did not do so, Barclay Oysters should have re-laid the oysters in other waters for a period before sale. But this possibility was not put to any witness and the whereabouts of the other waters and the cost of relaying the oysters were matters not explored in the evidence. I think it appropriate, on the evidence, to regard the alternative as simply one of ceasing business entirely or of marketing the oysters with an effective warning that effectively brought home the risk that the oysters might carry the HAV. But such a warning would have put the Barclay companies out of business. Accordingly, in substance, the true alternative to the course of conduct in fact pursued was to cease business.

It seems to me that on the evidence of the lack of any previous outbreak of health problems arising from the consumption of oysters grown in the Lake and the lack of knowledge otherwise of Mr Barclay of the existence of an actual problem as distinct from potential sources of faecal contamination of the Lake, the Barclay companies' duty of care did not reasonably require them either to take the course that his Honour outlined or to suffer a closure of their business until somehow they could be completely assured that they were putting into the market a product that was free of defects."

1. The course of proceedings raises a question as to the approach this Court should take in an appeal where there are concurrent findings of negligence (or absence of negligence) at a trial and in an intermediate appellate court. A recent example of such an appeal was Woods v Multi-Sport Holdings Pty Ltd[21]. In that matter, a trial judge in Western Australia had decided that the owner of an indoor cricket facility, who undoubtedly owed a duty of care to an injured player, had not been negligent in failing to provide certain protective equipment and in failing to give a certain warning. That decision was unanimously upheld by the Full Court of the Supreme Court of Western Australia. By majority, a further appeal to this Court was dismissed. All members of this Court examined in detail the reasoning of the trial judge for the purpose of deciding whether error was shown. The two dissenting judges, McHugh and Kirby JJ, both found that there was error, and favoured reversing the decision of the trial judge and the Full Court.
2. As Hayne J pointed out in Woods[22], although a finding of negligence (or absence of negligence) is conventionally described as a finding of fact, it also involves a normative judgment. The reasons given by the minority in Woods in favour of reversing the decision of the Western Australian courts illustrate the point. There was no disagreement with the trial judge on any matter of primary fact. The disagreement was with the judge's appreciation of the reasonableness of the conduct of the respondent, and with the weight given, or not given, by the judge to certain considerations bearing upon that question.
3. Concurrent findings may exist at different levels of particularity, and either with or without an element of normative judgment. In Bridgewater v Leahy[23], a case concerning an allegation of unconscionable conduct, there were concurrent findings that a transferor of land was not under any special disability, and that a transaction was not unconscionable. Both findings were reversed, by majority, in this Court.
4. In Waltons Stores (Interstate) Ltd v Maher[24], Deane J, referring to concurrent findings that a party to litigation entertained a certain belief, and had acted on a certain inducement, (findings of primary fact, involving no value judgment), said:

"This Court should not, in the absence of special reason such as plain injustice or clear error, disturb them. In a context [in which] the cost of litigation has gone a long way towards effectively denying access to the courts to the ordinary citizen who lacks access to government or corporate funding, it is in the overall interests of the administration of justice and of the preservation of at least some vestige of practical equality before the law that, in the absence of special circumstances, there should be an end to the litigation of an issue of fact at least when the stage is reached that one party has succeeded upon it both on the hearing before the court of first instance and on a rehearing before the court of first appeal."

1. Later, in Louth v Diprose[25], Deane J added that it was immaterial that the concurrent findings were of primary fact or involved conclusions and inferences drawn from primary facts, or that there were differences in the reasoning of the primary judge and the first appellate court, or that there was a dissentient in the first appellate court. He did not expressly refer to a difference between purely factual conclusions and conclusions that involved the application of standards of behaviour. However, in Baffsky v Brewis[26], Barwick CJ, with whom Stephen, Mason, Jacobs and Aickin JJ agreed, referred to the rule in relation to "concurrent findings of fact or concurrent views as to the exercise of a discretion." There is no reason to deny the application of the rule to a finding of negligence. However, whether there is "plain injustice or clear error" might be affected by the extent to which the decision involves value judgment, explicit or implicit.
2. The rule that an ultimate court of appeal will only disturb a finding of fact that is shown to be clearly erroneous appears to have originated in the nineteenth century in Privy Council appeals from India, and to have been gradually developed and extended to appeals to the Privy Council from all parts of the British Empire, and then to all courts of last resort[27]. In Owners of the "P Caland" and Freight v Glamorgan Steamship Co[28] Lord Watson said:

"[I]t is a salutary principle that judges sitting in a Court of last resort ought not to disturb concurrent findings of fact by the Courts below, unless they can arrive at - I will not say a certain, because in such matters there can be no absolute certainty - but a tolerably clear conviction that these findings are erroneous. And the principle appears to me to be specially applicable in cases where the conclusion sought to be set aside chiefly rests upon considerations of probability."

1. The rule exists alongside, but is not co-extensive with, the requirement that an appellate court will recognise the limitations on its capacity to make factual judgments where they depend in part upon the observation of witnesses who have been seen only by the trial judge. It has a different rationale. The legal system does not provide a second level of appeal in order to give any sufficiently determined litigant a third chance of success. Indeed, since the introduction of the requirement of special leave, there is no general right of appeal to this Court. The rule involves an acceptance that it is unjust that a litigant who has twice succeeded on an issue of fact should be deprived of the benefit of the success merely because an ultimate court of appeal would have taken a different view of the facts.
2. A judgment as to the reasonableness of the conduct of the Barclay companies in response to the risk of contamination required an evaluation of "the magnitude of the risk and the degree of probability of its occurrence". It also required an examination of "the expense, difficulty and inconvenience" of the available alternatives. For practical purposes, the alternative was a cessation of harvesting for an indefinite period, or for the remainder of the harvesting season, of the kind that ultimately occurred on 14 February 1997. When Lindgren J said that the alternative was "to cease business", or "to suffer a closure of their business until somehow they could be completely assured that they were putting into the market a product that was free from defects", he can hardly have been referring to something different from that which was done by all growers of Wallis Lake oysters on 14 February 1997. By that time of course, viral contamination was no longer merely a risk; it was an established fact. Even so, the temporary cessation of harvesting in November 1996 was a response to a recognised increase in the risk of contamination. It was followed by a resumption of harvesting and selling over the Christmas and New Year periods. The critical question for the Federal Court was whether, in the light of what was known about the nature and degree of the risk of contamination, that resumption of commercial activity was reasonable. I am not persuaded that any of the four judges in the Federal Court misunderstood, or failed to address, that question. The answer given by the majority was fairly open. Lindgren J answered the question differently; but I am not persuaded that the majority view involved clear error or injustice.

1. I would dismiss the appeals of the Barclay Companies (No S258/2001) and of Mr Ryan (No S259/2001) with costs. I would allow the appeal of the State (No S261/2001) with costs.
2. I agree with the concluding paragraph of the orders proposed by Gummow and Hayne JJ.
3. GAUDRON J. I agree with the orders proposed by Gummow and Hayne JJ and with their Honours' reasons. There is, however, one matter upon which I would make separate comment. That matter concerns the relationship between certain specific obligations cast upon a corporation by the Trade Practices Act 1974 (Cth) ("the Act") and the general law of negligence.
4. For present purposes it is sufficient to refer to two provisions of the Act upon which Mr Ryan relied unsuccessfully at first instance. The first is s 52(1) which provides:

" A corporation shall not, in trade or commerce, engage in conduct that is misleading or deceptive or is likely to mislead or deceive."

Pursuant to s 82 of the Act, a person who suffers loss or damage by conduct that contravenes certain provisions of the Act, including s 52(1), is entitled to recover the amount of that loss or damage.

1. The second provision of the Act which invites attention is s 75AD, which is in Pt VA of the Act. That Part is concerned with the liability of manufacturers and importers of defective goods. "Manufactured" is defined in s 75AA to include "grown, extracted, produced, processed and assembled."
2. Section 75AD imposes liability on a corporation, which in trade or commerce supplies goods manufactured by it, to pay compensation to any individual who suffers injury because of a defect in those goods. By s 75AK(1), it is relevantly a defence to a claim for compensation under Pt VA of the Act, including s 75AD if it is established that:

"(a) the defect in the ... goods that is alleged to have caused the loss did not exist at the supply time; or

(b) they had that defect only because there was compliance with a mandatory standard for them; or

(c) the state of scientific or technical knowledge at the time when they were supplied by their actual manufacturer was not such as to enable that defect to be discovered".

1. Were the general law of negligence to develop to a point where, in circumstances in which ss 52 and 75AD operate, it imposed more onerous obligations than are imposed by those provisions, it would, in my view, be necessary to consider whether those provisions had supplanted the general law. And the same may well be true of other provisions in the Act. However, as the reasons of Gummow and Hayne JJ demonstrate, the general law of negligence has not yet developed to that point.
2. To say that it is not yet necessary to consider whether particular provisions of the Act have supplanted the general law in the circumstances in which they operate is not to say that the questions posed by particular provisions of the Act are unrelated to those posed by the general law of negligence. Thus, if the supply of goods by a corporation in trade or commerce without warning as to their possible dangers or defects does not constitute conduct that is likely to mislead or deceive for the purposes of s 52(1) of the Act, as was held at first instance in this case[29], it is difficult to conceive that, nonetheless, the general law would impose a duty to warn as to those dangers or defects.
3. Although different concepts inform the law of negligence, ordinarily there is a duty to warn only if there is a foreseeable risk that a person will be led to believe that something is safe when it is not. And if conduct by a corporation would have that consequence, it would seem inevitable that that conduct would be likely to mislead or deceive for the purposes of s 52(1) of the Act.
4. A somewhat different issue is raised by the defence provided by s 75AK(1)(c) to a claim for compensation under s 75AD for injury resulting from defective goods. At first instance, Mr Ryan's claim for compensation under s 75AD was dismissed because, in terms used in s 75AK(1)(c), "the state of scientific or technical knowledge at the time when [the oysters] were supplied ... was not such as to enable [the] defect to be discovered"[30]. Once it was concluded that scientific or technical knowledge did not permit discovery that the oysters grown at Wallis Lake had been contaminated by the hepatitis A virus, a question then arose as to what, if any, action could have been taken to avoid a risk of injury to Mr Ryan. As Gummow and Hayne JJ point out, the only possible courses, over and above the precautions already taken, were to cease selling oysters grown at Wallis Lake or, which was likely to have the same effect, to warn as to their possible viral contamination.

1. In December 1996 and early January 1997, Mr Ryan and his family consumed oysters purchased from Barclay Distributors Pty Ltd. The oysters were grown in the Wallis Lake in New South Wales. In late January 1997, Mr Ryan began to feel unwell. Blood tests revealed that he was suffering from the hepatitis A virus ("HAV"). The Department of Health reported that notifications of HAV began to increase in the week commencing 20 January 1997, peaking on 3 February 1997. By 10 February 1997, the Department had established a link between those infected with HAV and the consumption of oysters grown in the Wallis Lake. A New South Wales government taskforce ultimately attributed 444 cases of HAV to the consumption of oysters grown in the Lake.

1. HAV is spread by the "faecal-oral route" − it is contracted when humans ingest material contaminated with human faeces which contains the virus. It can only be transmitted through human faeces. HAV has an incubation period of between 15 and 50 days; most cases of infection occur within 30 days of contact. It is a resilient virus that can survive in the environment for periods of three months or longer.
2. Oysters are filter feeders, processing 10 to 20 litres of water per hour by sucking water in and excreting particles through the oyster's normal digestive processes. Some particles, including those that contain HAV, are retained while others are excreted. HAV does not attack oysters; ordinarily the virus is retained in the oyster's flesh. Viral contamination of the oyster is likely to be at a level of concentration that far exceeds the concentration of the virus in the water.

1. Wallis Lake is the largest oyster growing area in New South Wales. Although oysters have been grown in the Lake for nearly a century, there was no record of HAV contamination before the outbreak in late 1996. Occasionally, however, faecal contamination occurred in the Lake.
2. The catchment area of the Lake includes the major towns of Forster and Tuncurry, various smaller townships and homes built along the rivers and countryside but which are not part of any township. Sixty-five percent of the area of the Lake is within the boundaries of the Great Lakes Council. Faecal waste from septic tanks and treatment sites could escape at numerous points within the Lake's catchment area and enter the Lake through storm water drains. During the period 1989-1993, the Council occasionally detected faecal contamination when testing water in the Lake. It did no testing in 1996.
3. Faecal waste was more likely to enter the Lake after periods of heavy rainfall. Between 23 and 25 November 1996 − shortly before the HAV outbreak occurred − heavy rain fell in the Lake catchment area.

1. Since 1983, health regulations required oysters grown in New South Wales to be depurated for a period of at least 36 hours to avoid contamination. Under the depuration process the oysters are placed in tanks of clean and disinfected estuarine water to which ultra-violet light is applied to destroy viruses and bacteria in the water. However, the ultra-violet light does not destroy viruses unless it contacts them. Expert evidence established that while depuration, carefully performed, provides satisfactory results, shellfish can retain viruses after depuration when they are taken from heavily polluted waters. Polymerise chain reaction ("PCR") testing constitutes the only effective method of detecting HAV in oysters. In November 1996, however, that method was still in the research stage. Only a limited number of laboratories could carry out the tests. Moreover, PCR testing was very expensive, destroyed the oyster, and frequently returned false negatives.
2. Following heavy rain − known as a "fresh" − the practice of the industry was to suspend harvesting until the water had cleared. In accordance with this practice, Graham Barclay Oysters Pty Ltd did not harvest oysters between 23 and 27 November 1996. On 11 February 1997, when the Barclay companies became aware of the HAV outbreak, they ceased harvesting and recalled oysters they had sent to distributors and retailers. On 14 February 1997, all Wallis Lake oyster growers voluntarily ceased harvesting. The Barclay companies did not resume harvesting until the 1997-98 season.
3. Oyster flesh tests revealed that faecal contamination was widely disbursed throughout the estuary. A sanitary survey was conducted to locate the sources of the pollution and to eliminate them. The faecal contamination emanated from multiple points, the vast majority being land-based sources.

Liability of public authorities − the Council and the State

1. A public body invested with a discretionary statutory power may be in breach of a common law duty of care if it fails to exercise the power for the benefit of an individual or class of individuals. In these cases, failure to exercise the power given constitutes actionable negligence that sounds in damages[36]. In determining whether a public authority has breached a common law duty by failing to exercise a statutory power, it is essential to examine the words and policy of the legislation[37]. That is because the legislation may indicate that the legislature has legislated to cover the field and excluded all common law duties of care[38]. In other cases, the imposition of a common law duty may be inconsistent with or undermine the effectiveness of the duties imposed by the statute[39]. In some cases, the circumstances of the case − for example, active intervention by the authority or reliance by the plaintiff − may establish a duty of care. But the legislation may give the authority such a wide discretion to exercise the power in question that the tribunal of fact cannot find that the failure to exercise the power constituted a breach of the duty.
2. Legislatures often vest discretionary powers in public authorities for the specific purpose of protecting the community. Some powers may be vested in the authorities for the protection of a specific class of persons who may be exposed to risks of harm that they are powerless to avoid and sometimes unable to identify. But the legislature has made these powers exercisable at the discretion of the authorities, and the common law does not seek to convert the statutory discretion into a positive common law duty to exercise it for the benefit of the public or one of its members. This is so even in those cases where mandamus will lie to compel the performance of the public duty to give proper consideration to whether a public authority should exercise a power[40]. Mandamus lies for breach of a duty owed to the public. Any person with a sufficient interest in the performance of the duty may bring an action for mandamus requiring that the public authority comply with the conduct that is the subject of the duty. But common law duties are owed to individuals. Unless the proper inference from the statute is that an individual has "a personal right to the due observance of the conduct, and consequently a personal right to sue for damages if he be injured by a contravention"[41], breach of the statutory duty does not sound in damages.

"The statutory power in question is not simply another of the multitude of powers conferred upon local authorities such as the Shire. It is a power addressed to the special risk of fire which, of its nature, can imperil identifiable life and property. Therefore, the nature of the power enlivens particular attention to its exercise and to the proper performance of a decision whether to give effect to it or not."

1. Similarly, in Brodie v Singleton Shire Council[49], Gaudron, Gummow JJ and I said that:

"on occasions, the powers vested by statute in a public authority may give it such a significant and special measure of control over the safety of the person or property of citizens as to impose upon the authority a duty of care. This may oblige the particular authority to exercise those powers to avert a danger to safety or to bring the danger to the knowledge of citizens otherwise at hazard from the danger. In this regard, the factor of control is of fundamental importance[50]."

1. Where a plaintiff claims that a public authority owed him or her an affirmative duty of care in a situation that has not yet been recognised by the common law, the court must examine a number of matters to determine whether the duty existed. I pointed to these matters in Crimmins v Stevedoring Industry Finance Committee[51]:

. Would a reasonable public authority reasonably foresee that its act or omission, including a failure to exercise its statutory powers, might result in injury to the plaintiff or his or her interests?

. Was the authority in a position of control and did it have the power to control the situation that brought about the harm to the injured person?

. Was the injured person or his or her interests vulnerable in the sense that the injured person could not reasonably be expected to adequately safeguard himself or herself or those interests from harm?

. Did the public authority know, or ought it to have known, of an existing risk of harm to the plaintiff or, in some cases, to a specific class of persons who included the plaintiff (rather than a risk to the general public)?

. Would the imposition of the duty of care impose liability with respect to the defendant's exercise of "core policy-making" or "quasi-legislative" functions?

. Is there any supervening policy reason that denies the existence of a duty of care?

1. If the first four of these questions are answered in the affirmative and the fifth and sixth questions in the negative, the court will ordinarily hold that the authority owed a duty of care to the plaintiff[52]. Conversely, if any of the first four questions are answered in the negative or either of the fifth and sixth questions are answered in the affirmative, ordinarily no duty of care will arise.

1. The first question in these appeals is whether the Council or the State should have reasonably foreseen that a failure to exercise its statutory powers might result in harm to oyster consumers by reason of the faecal contamination of oysters. If that question is answered in favour of the Council or the State, no duty of care existed. It would then be unnecessary to examine other features of the case to see if they pointed to a duty of care owed by the State or the Council to the plaintiff. In this and other cases, it is somewhat artificial to separate the issue of reasonable foreseeability from the issue whether the persons affected − oyster consumers − were so closely and directly affected by the conduct of the State or Council that either, or both, of them should have had the oyster consumers in mind when considering to act or not to act. However, in this case, the two issues seem sufficiently separate to warrant separate treatment.
2. In determining whether a defendant should have reasonably foreseen a risk of injury, it is not necessary that the defendant should have foreseen the precise risk of injury or how it occurred. It is sufficient that the risk is one of a class of risk that in a general way the defendant should have foreseen[53]. If the authority should have foreseen the class of risk, a further question arises as to whether the risk could be reasonably disregarded[54]. Reasonable foreseeability involves more than a question of fact. It involves a value judgment. Would a reasonable person in the position of the defendant not only have foreseen that his or her conduct − including omissions − gave rise to a risk of injury, but regarded it as sufficiently serious to consider what steps should be taken to avoid or reduce it?
3. On the evidence, both the State and the Council should have foreseen that the presence of faecal contamination gave rise to a risk of harm to the consumers of oysters. Oysters grown in waters, subject to the run-off of faecal matter, are subject to the risk of contamination from faecal pollution. That contamination carries with it the risk of HAV infection. Although depuration cleans oysters and makes them fit for human consumption, it does not guarantee the removal of contaminants. Both the State and the Council should reasonably have foreseen the risk of injury to the consumers of oysters from the faecal contamination of the Lake.
4. But would a reasonable public authority think that this risk of harm from faecal contamination was so negligible that it could be reasonably disregarded? In my opinion, although the risk of injury was very low, the consequences of faecal contamination were not so negligible that a reasonable authority would disregard the risk to anyone with whom it had a direct and close relationship. It is true that, in the history of oyster harvesting in the Wallis Lake region, no outbreak of the kind that occurred in this case had happened. However, health authorities and the industry knew the injurious consequences that could flow from the faecal contamination of oysters. One consequence was HAV infection. The likely effect of a HAV outbreak on oyster consumers makes it impossible to conclude that a public authority such as the State or the Council could reasonably disregard the risks of contaminated oysters being made available for consumption. No reasonable public authority would regard the risk of HAV from contaminated oysters as so small and inconsequential that it could be ignored without inquiring into what reasonable steps could be taken to avoid that risk, if other factors pointed to the existence of a duty of care.

Control − the power to control and knowledge of harm to the plaintiff

1. Central to the plaintiff's case that the State owed him a duty of care was the proposition that it exercised managerial control over the Wallis Lake oyster industry. Where an individual has control of land or chattels or undertakes a task, courts will usually find that that individual has a duty to take reasonable care for the safety of those entering the land or affected by the use of the chattels or the execution of the task[55]. Often enough the courts will have little difficulty in holding that a public authority that exercises its power to carry out, or an authority that undertakes to carry out, a task has a duty to take care for the safety of those affected by the task[56]. But the position of the Executive government of a polity is different from the position of individuals and other public authorities.
2. The powers and functions of the government of a polity are generally invested for the benefit of the general public. In the absence of a statutory direction, the mere existence of such a power in that government imposes no duty to exercise it for the protection of others. In that respect, its situation is analogous to a private citizen who, absent special circumstances, has no duty to take affirmative action to protect another person from harm[57]. Nor does the bare fact that the Executive government has exercised its powers from time to time create any duty to exercise its powers. Such exercises of power do not constitute "control" of an activity in the sense that that expression is used in the law of torts. They are merely particular exercises of powers that were invested in the Executive government for the benefit of the general public to be exercised at the discretion of the Executive government. Unless a particular exercise of power has increased the risk of harm to an individual, the Executive government of a polity does not ordinarily owe any common law duty to take reasonable care as to when and how it exercises its powers. No doubt circumstances may arise where conduct of the government, short of increasing a risk of harm, creates a duty of care. But such cases are less likely to arise than in the case of other public authorities. In particular, knowledge of specific risks of harm or the exercise of powers in particular situations is less likely to be a factor in creating a duty than in the case of an ordinary public authority. This is because the powers and functions of the Executive government are conferred for the benefit of the public generally and not for the benefit of individuals.

"(a) the State owned, and had powers of control over, the lake;

(b) through the Department of Fisheries, it established, and supervised the operations of, a mosaic of oyster leases;

(c) through the Department of Fisheries, it issued, and enforced the provisions of, aquaculture permits;

(d) through the Department of Health, the State supervised the depuration process, including the nature and location of water intake points and the design, construction and maintenance of depuration tanks and ultra-violet facilities;

(e) through the EPA, the State had powers under the Clean Waters Act to remove, disperse, destroy or mitigate pollution of waters (s 27) and to carry out inspections and investigations of premises (s 29);

(f) through a number of agencies, the State was a participant in the Wallis Lake estuary management committee, one of whose objectives was to prepare a management plan designed 'to sustain a healthy, productive and attractive estuary'; and, most importantly,

(g) through the Minister for Fisheries, it had the power − at any time, to prohibit the taking of oysters from the lake."

1. But these matters mean no more than that the Executive government of the State was exercising or could exercise various powers given to it by its legislature. They do not constitute "control" of the industry in any relevant sense.
2. The judgment of Gummow and Hayne JJ refers to the relevant legislation under which the Executive acted or could act[60]. In a political sense and for public law purposes, this legislation enabled the State to supervise and manage all fisheries in New South Wales and to control fisheries through the issuing of leases. However, supervision, management or control in this sense or for this purpose is different from the sorts of control that, in other cases concerning public authorities, have caused courts to hold that a duty of care existed. In Brodie, the legislation empowered the Council to design or construct roads and to carry out works or repairs upon them, powers that councils had frequently used. In those cases, councils had complete control over the state of the roads. They also had power to attend to any defects that would expose road users to injury. It was this combination of power, direct control and the undertaking of functions in accordance with their powers that gave rise to a duty of care. In Crimmins, the object of the powers vested in the Authority was to secure the expeditious, safe and efficient performance of stevedoring operations. The Authority could make whatever orders it saw fit including the regulation of stevedoring operations to encourage safe working conditions. The Authority had power to bring proceedings against any employer who did not comply with the provisions requiring safe working practices. But most important of all, the Authority had used its powers to direct waterside workers to places of work that contained reasonably foreseeable risks of injury to the workers. This last point alone was sufficient to create a duty of care although the case was not conducted on that basis. I do not regard Pyrenees as a "control" case. Rather it is a case where the Council came under a duty of care because it knew of the risk of harm to specific individuals, it had power to take steps to eliminate the risk and importantly, at an earlier stage, had given directions to eliminate the risk.
3. In my opinion, the State had no relationship with the consumers of oysters that imposed on the State an affirmative duty to protect those consumers from harm created by the growers and distributors of oysters. That is so, even though the State ought to have reasonably foreseen that, unless it acted, oyster consumers might suffer harm. Knowledge or imputed knowledge that harm may result from a failure to take affirmative action is not itself sufficient to create an affirmative duty of care.

1. The Local Government Act 1993 (NSW) granted the Council a wide array of powers to control pollution. Nevertheless, the statutory powers of the Council gave it less "control" over the Wallis Lake oyster industry than the "control" that the State had over the industry. Indeed, the Council, unlike the State, had no specific powers or functions in respect of oysters or the oyster industry. Nor did the fact that the Council had monitored the water quality of the Lake from 1989 to 1993 constitute "control" of those waters for the purposes of this branch of the law. The monitoring was carried out in the exercise of discretionary powers. It was for the Council to decide if and when it should monitor the Lake. Its monitoring created no relationship with oyster consumers such that the failure to continue monitoring was a breach of a common law duty of care. The Council had no control over the industry in any relevant sense.
2. However, the learned trial judge found[61] that the Council owed a duty of care to Mr Ryan because it knew of the risk of harm from faecal pollution and it had the power to deal with the pollution problem. As formulated by his Honour, the Council owed a duty of care to oyster consumers to take reasonable steps to minimise human faecal contamination of Wallis Lake. His Honour pointed to a number of matters within the knowledge of the Council that in his view created the duty. They included[62]:

. Wallis Lake was used for growing oysters for human consumption;

. the catchment area contained many potential sources for contaminating the Lake with human faecal material;

. the HAV virus is commonly transmitted in the faeces of infected persons;

. the HAV virus is capable of surviving for long periods in estuarine waters;

. no procedure (such as depuration or testing) can prevent HAV contaminated oysters reaching the public; and

His Honour also referred to the Council having extensive statutory powers to control the sources of pollution in the catchment area.

1. However, a public authority does not come under an affirmative duty of care merely because the authority knows that unless it acts an individual will suffer harm[63]. Nor is the present case like Pyrenees where the Council knew of a risk of harm to certain individuals from a specific problem.
2. In my opinion, the learned trial judge erred in finding that the Council owed any duty of care to Mr Ryan. There was simply no relationship between the Council and oyster consumers sufficient to create a duty of care. This Court no longer sees proximity as the criterion of a duty of care. But no duty of care can arise unless the relationship between the parties is one of neighbourhood in Lord Atkin's sense as stated in Donoghue v Stevenson[64]. To create a duty, the relationship between the public authority and persons affected by the conduct of the authority must be "so closely and directly affected by [its] act [or omission] that [it] ought reasonably to have them in contemplation as being so affected"[65] when it directs its mind to the relevant conduct in question. In considering whether it should exercise its powers over pollution, the Council was no more concerned with oyster consumers than any other section of the public or individual. There was no close and direct relationship between oyster consumers and the Council such that it had a duty to take care for the safety of each and every one of them. In that respect, the Council stood in a different position from that of the Barclay companies who had a direct relationship with the consumers of their product. Here there was nothing to suggest that the relationship between the Council and the consumers of Wallis Lake oysters imposed on the Council an affirmative duty to take reasonable care to protect those consumers from harm caused by eating those oysters.
3. Accordingly, the Full Court did not err when it upheld the Council's appeal against the trial judge's finding that the Council owed Mr Ryan a duty of care.

1. The Barclay companies accepted that they owed oyster consumers a duty of care to ensure that the oysters were safe for human consumption. The issues in relation to the Barclay companies related to the scope of the duty of care that they owed to oyster consumers and whether there was a breach of that duty.
2. At all material times, Mr Barclay knew that potential sources of viral pollution existed in Wallis Lake, that depuration was not adequate to remove viruses completely and that E-coli oyster meat testing would not necessarily reveal the existence of viruses. On this evidence, the learned trial judge held[66] that a prudent oyster grower needed to do more than depurate and rely on E-coli flesh tests because those steps provided insufficient protection against a known danger. His Honour said that the only real protection to consumers was to prevent viral contamination from occurring and the Barclay companies were obliged to take the steps reasonably open to it to obtain a virus-free growing environment. Failing this, the companies had to refrain from selling oysters unless they contained a warning about the risks of consumption.
3. His Honour saw the carrying out of a survey of sanitary sources as one way of reducing the risk of a contaminated environment. His Honour recognised that any sanitary survey would require State or local government involvement. But he said that, given that the Barclay companies produced a product that put consumers at risk, they could not say that the making of a sanitary survey was someone else's responsibility. The trial judge said that neither the Barclay companies nor any of the committees with which they were associated had attempted to procure any governmental involvement in making a survey[67]. His Honour concluded[68] that in selling oysters, grown in waters known to be open to possibly undetectable viral contamination, and without any warning as to this danger, the Barclay companies had breached the duty of care they owed to oyster consumers.
4. In the Full Court, Lee and Kiefel JJ formulated the duty differently from the trial judge but they dismissed the Barclay companies' appeal. Lee J said[69] the content of the duty required the Barclay companies to refrain from harvesting and selling oysters from the Lake when conditions had arisen which they knew had increased the risk of oyster contamination. Until the Barclay companies had taken the necessary steps to show that the resumption of oyster harvesting was safe, sales of oysters should have been halted. His Honour said that, if the trial judge had intended to limit the scope of the duty to the provision of notice to consumers of the nature of the risk at the time of sale, his statement of the duty was inadequate. Kiefel J found[70] that the duty required the Barclay companies to refrain from selling oysters for human consumption until a "sufficient period" had elapsed for the risk of contamination to be regarded as acceptable or testing indicated this to be so.

1. I would allow the appeals by the State and by Graham Barclay Distributors Pty Ltd with costs. I would dismiss the appeal by Mr Ryan with costs. I would allow the appeal by Graham Barclay Oysters Pty Ltd in so far as it concerns the issue of negligence but make no order as to costs.

1. These three appeals are brought against a decision of the Full Court of the Federal Court[75]. They involve the alleged liability in negligence of particular growers and distributors of oysters, and relevant local and State governments, for harm suffered by consumers of oysters. The consumers contracted the hepatitis A virus as a consequence of eating oysters grown at Wallis Lake. This is located within the Shire of Great Lakes in New South Wales. The oysters were harvested from waters polluted by human faecal contamination. One consumer, Mr Grant Ryan, instituted a representative action in the Federal Court under Pt IVA of the Federal Court of Australia Act 1976 (Cth), on behalf of himself and other consumers. Additional representative applicants were, by leave, subsequently joined to the proceeding[76]. The respondents were Graham Barclay Oysters Pty Ltd ("Barclay Oysters") and Graham Barclay Distributors Pty Ltd ("Barclay Distributors") (together "the Barclay companies") and other oyster growers and distributors, the Great Lakes Council ("the Council") and the State of New South Wales ("the State"). The Barclay companies, the Council and the State entered cross-claims against one another.
2. At first instance, the Federal Court (Wilcox J) held that the Council, the State and the Barclay companies were each liable in negligence to Mr Ryan and (subject to proof of damage) to the other 184 representative group members[77]. The Full Court of the Federal Court (Lee, Lindgren and Kiefel JJ), by differently constituted majorities, upheld an appeal by the Council, and dismissed appeals by the State and the Barclay companies. In this Court, Mr Ryan seeks to restore the initial finding of negligence against the Council, while the Barclay companies and the State seek to have the negligence findings against them overturned. The appeal by the State should be allowed and that by Mr Ryan against the Council should be dismissed. In the appeal by the Barclay companies, the appeal by Barclay Distributors should be allowed. (The appeal by Barclay Oysters raises other considerations with respect to the proper outcome to which reference later will be made.) In general terms, this result follows that favoured by Lindgren J in the Full Court.

1. The hepatitis A virus multiplies, and is symptomatic, only in humans. It is contracted when humans ingest material contaminated by infected human faeces. When grown in contaminated water, oysters retain pathogens, including the hepatitis A virus, in concentrated form. Hepatitis A is capable of surviving in food and in fresh or salt water for prolonged periods. There was evidence before the primary judge that the virus may survive in the environment for months or even years, remaining a potential threat for the whole of that time. The taste and appearance of oysters is not affected by the presence of hepatitis A.
2. The oyster harvesting season at Wallis Lake ordinarily extends from mid‑October until April. Barclay Oysters is the largest oyster grower at Wallis Lake. In the period 22‑25 November 1996, there was heavy rainfall in the region. The run‑off caused by heavy rain brings with it an increased risk of viral contamination of oysters. For this reason, oyster growers generally desist from harvesting during or after heavy rainfall. It appears that the Barclay companies ceased harvesting oysters by 9.00 am on 23 November 1996. They did not recommence harvesting until 27 November, two days after the rainfall had finished.
3. Sample oysters tested by the Barclay companies between 26 November 1996 and 9 January 1997 tested negative for E‑coli bacteria. This suggested, but did not establish, that the samples were free from viral contamination. During this period, the Barclay companies continued to harvest oysters and to supply them to distributors for sale to the public. In accordance with their usual practice, the Barclay companies depurated the oysters for 36 hours after harvesting them. Depuration involves the submersion of oysters in clean estuarine water, disinfected by ultra‑violet radiation. The primary judge found that this is a useful but not entirely effective means of ensuring the safety of shellfish.
4. On 21 December 1996, Mr Ryan's father purchased six dozen oysters from the Barclay companies. They were consumed by members of the Ryan family, including Mr Ryan, on Christmas Day. Mr Ryan's brother purchased a further 10 dozen oysters from the Barclay companies on 31 December, giving two dozen to Mr Ryan, who ate them a few nights later. On 30 January 1997, Mr Ryan began to feel unwell. On 3 February, he was diagnosed with hepatitis A.
5. Mr Ryan's diagnosis coincided with a general increase in hepatitis A notifications in New South Wales. By about 10 February 1997, the New South Wales Department of Health had established the probability of a connection between the hepatitis A epidemic and Wallis Lake oysters. On 11 February, Mr Barclay was informed of this connection by the Council and the Tamworth Area Health Service. The Barclay companies immediately recalled oysters from their customers. On 14 February 1997, the Wallis Lake growers decided to cease harvesting. The Barclay companies did not resume harvesting until the commencement of the 1997‑1998 season.

1. The trial judge accepted expert evidence that the pollution of the lake emanated from multiple sources. His Honour found that inadequately treated human effluent entered the oyster-growing areas of the lake primarily from land-based locations, although faecal discharge from one or more watercraft may have contributed to the problem. Much of the pollution came from stormwater drains and local sewerage facilities, including septic tanks in caravan parks, tourist facilities and private residences.
2. The Court dismissed claims by Mr Ryan that the Barclay companies were liable under s 74C (false descriptions) or s 75AD (defective goods causing injuries) of the Trade Practices Act 1974 (Cth) ("the Trade Practices Act") or had contravened s 52 (misleading or deceptive conduct) or the conditions implied by s 71 (merchantable quality and fitness for purpose) of that statute.
3. As noted, the primary judge held each of the Council, the State and the Barclay companies liable in negligence to the relevant consumers. His Honour further held that Mr Ryan was entitled to succeed in his personal claims against Barclay Oysters under s 74B (fitness for purpose) and s 74D (unmerchantable quality) of the Trade Practices Act. As the application of those provisions to the circumstances of the group members in the representative action required further findings of fact, the Court ordered that the portion of Mr Ryan's representative claim respecting ss 74B and 74D be reserved. Wilcox J awarded damages in Mr Ryan's personal claims at $30,000, apportioned equally between the three respondents.
4. Order 2 of the orders made by Wilcox J was as follows[78]:

"it be declared that [Mr Ryan] is entitled to succeed against each of [the Council, the State and the Barclay companies] in respect of that portion of his representative claim that alleges negligence, but only on behalf of those group members who prove damage has been suffered by them".

1. It is to be noted that, the dismissal of claims based on s 74C, s 75AD, s 52 and s 71 of the Trade Practices Act apart, the only final judgment at trial was that for Mr Ryan on his personal claims. The remaining claims the subject of the group proceeding were not finally decided. Orders that were made in connection with those other claims were, therefore, interlocutory orders. It then is apparent that it was inappropriate to make the order in the terms set out above which were expressed in the form of a declaration. "Interlocutory declaration" is a form of order not known to the law yet that, in effect, is the nature of the order that was made, expressed, as it was, in declaratory terms[79]. The making of an order in that form in this case was not only wrong, its making may obscure some questions which the claims made in the proceeding inevitably present.

1. The detailed provisions in the Trade Practices Act which were relied upon in this litigation may raise a question respecting the significance to be attached to comprehensive federal statutory provisions upon a particular subject where it is sought, concurrently, to develop the Australian common law in that field. In Perre v Apand Pty Ltd[80], reference was made to what in the United States is known as a "pre‑emption" doctrine. This restricts the development of the common law of the several States of the Union, in fields such as unfair competition, where federal legislation, respecting such matters as patents, copyright and designs, makes provision. In Australia, s 109 of the Constitution deals only with conflict between federal and State laws. It remains to be seen whether some adaptation of the "pre‑emption" doctrine may apply in the development of the Australian common law.
2. The relationship between claims made for relief in respect of contravention of provisions of the Trade Practices Act and common law claims, whether in negligence, deceit or otherwise, has not been examined in detail in any decision of this Court and was not the subject of detailed argument in the present matters. In those circumstances, we proceed on the assumption (which was not challenged) that a plaintiff may frame alternative claims in negligence and under the provisions of the Trade Practices Act relied on here. But it is to be recognised that claims of the kind which were made in these matters, in negligence and under the Trade Practices Act, were alternative claims, and that, if a group member succeeds in establishing the elements of both claims, that group member must elect which remedy will be taken[81]. That election would have to be made no later than at the time of seeking final judgment in the action.

1. A majority of the Full Court of the Federal Court (Lindgren J and Kiefel J, Lee J dissenting) allowed an appeal by the Council, holding that it owed no relevant duty of care to the oyster consumers. A differently constituted majority (Lee J and Kiefel J, Lindgren J dissenting) dismissed an appeal by the State, upholding the primary judge's conclusion respecting its liability in negligence to the consumers. By majority, the Full Court (Lee J and Kiefel J, Lindgren J dissenting) also upheld the primary judge's conclusion that the Barclay companies were liable in negligence to Mr Ryan. Further, the Full Court upheld the primary judge's conclusion with respect to the liability of Barclay Oysters under ss 74B and 74D of the Trade Practices Act. In the result, the Full Court reduced the damages awarded to Mr Ryan in his personal claims by $3,000 to correct what the parties agreed was an error in the calculation of the interest payable.
2. The grounds of the appeals to this Court are concerned only with the claims in negligence. It is convenient to consider the claims under three main headings: first, the position of the Council; secondly, the State; and, finally, the Barclay companies.

The claims in the Federal Court against the Council

1. These have fluctuated in the course of the litigation. By their re‑amended statement of claim dated 21 April 1998, Mr Ryan and the other applicants submitted that the Council owed them (i) a duty regularly to monitor and test the waters, sediment and sea grasses of the Wallis Lake region for contamination and to monitor the impact of private landholders and the Council's sewerage systems on the water quality; (ii) at least in and after late November 1996, a duty to warn oyster farmers, wholesalers and retailers and the general public of the likely contamination of Wallis Lake and the likely unsafety of oysters harvested therefrom; (iii) a duty to take steps, directly or indirectly, to cause oyster farmers in the Wallis Lake region to cease the harvesting or supply of oysters in and after November 1996; (iv) a duty to set up and supervise the Wallis Lake Estuary Management Committee to report on and implement steps in respect of the management of water quality in the Wallis Lake region; and (v) a duty not to contaminate Wallis Lake and to ensure that the lake's water quality was not compromised by the Council's systems for the management of sewage (including by ensuring the maintenance of sewerage facilities in a proper state of repair). As will appear, not all of these claims were ultimately pursued in this Court.
2. At trial, Wilcox J held that the Council owed a common law duty of care to oyster consumers to take those steps that were reasonably open to it to minimise human faecal contamination of the lake[82]. His Honour held that the Council had breached this duty by failing to take steps to identify pollution sources and by failing to take "whatever steps were necessary to ensure the problem was fixed", including through the exercise of certain statutory powers[83]. In particular, his Honour found that the "responsible reaction" to complaints which the Council was receiving in respect of malfunctioning septic tanks would have been to institute a "sanitary survey", especially of premises that drained to estuarine waters[84]. His Honour used the term "sanitary survey" to refer to a comprehensive inspection of the foreshores and tributaries of a waterway, complemented by a programme of water testing, to identify sources of pollution and determine their effect on the quality of the water. The trial judge found that, rather than instituting such a survey, the Council determined, in May 1996, to stop responding to complaints about malfunctioning septic tanks. Before this Court, the Council challenged that finding by Notice of Contention.

1. Before identifying the precise way in which the alleged duty was formulated by counsel for Mr Ryan in submissions to this Court, it is appropriate to describe the statutory provisions which empowered the Council to act in respect of the situation at Wallis Lake.
2. The Council is constituted as a body corporate under Ch 9 of the Local Government Act 1993 (NSW) ("the LG Act"). At the time of the events giving rise to this litigation, s 7 of that statute provided that the purposes of the LG Act included to provide the legal framework for an "environmentally responsible" system of local government (par (a)) and to require councils "to have regard to the protection of the environment in carrying out their responsibilities" (par (e)). Chapter 7 (ss 68‑185) of the LG Act was headed "What are the regulatory functions of councils?". Section 68 set out a wide range of activities which generally required prior council approval; these included broadly defined categories of conduct in respect of water supply, sewerage and stormwater drainage work and the management of waste. Failure to obtain a requisite approval, and the carrying out of an activity otherwise than in accordance with an approval, were rendered criminal offences by ss 626 and 627. Clause 45 of the Local Government (Water, Sewerage and Drainage) Regulation 1993 (NSW), made under s 748 of the LG Act, relevantly directed the Council, in determining an application under s 68 of the LG Act for approval to carry out sewerage work, to have regard to, among other things, "the protection and promotion of public health" and "the protection of the environment".
3. Further, the Council was empowered by s 124 of the LG Act to order specified persons to do or to refrain from doing a range of things in prescribed circumstances. The orders contemplated by that provision included: (i) orders requiring owners, occupiers, managers or licensed contractors to bring sewerage systems into compliance with relevant standards or requirements set or made by or under the LG Act (Item 5); (ii) orders requiring owners or occupiers of land to do or to refrain from doing specified things to prevent or to repair environmental damage, in circumstances where work carried out on land had caused or was likely to cause drainage-related environmental damage (Item 11); (iii) orders against any person apparently engaged in promoting, conducting or carrying out an activity that constituted or was likely to constitute a threat to public health or safety (where the activity was not regulated or controlled under any other Act by a public authority) (Item 15); and (iv) orders requiring owners or occupiers of premises not to use or to permit the use of a human waste storage facility on premises after a specified date, where such an order was necessary to protect public health (Item 25).

1. Before this Court, counsel for Mr Ryan contended that the Council owed the oyster consumers a duty (i) to exercise the powers conferred by ss 191 and 192 of the LG Act to carry out a sanitary survey of Wallis Lake and its tributaries and (ii) after identifying sources of pollution, to exercise its powers under ss 124 and 678 of the LG Act or s 27 of the Clean Waters Act to remedy those problems.
2. Similarly, counsel for the Barclay companies (in this respect supporting the case made by Mr Ryan) sought to apply to the present appeal a description in the joint judgment in Brodie v Singleton Shire Council[87] of the duty owed by authorities of the type considered in that case. There, Gaudron, McHugh and Gummow JJ said[88], in a passage with which Kirby J agreed[89]:

"Authorities having statutory powers of the nature of those conferred by the [Local Government Act 1919 (NSW)] upon the present respondents to design or construct roads, or carry out works or repairs upon them, are obliged to take reasonable care that their exercise of or failure to exercise those powers does not create a foreseeable risk of harm to a class of persons (road users) which includes the plaintiff. Where the state of a roadway, whether from design, construction, works or non-repair, poses a risk to that class of persons, then, to discharge its duty of care, an authority with power to remedy the risk is obliged to take reasonable steps by the exercise of its powers within a reasonable time to address the risk. If the risk be unknown to the authority or latent and only discoverable by inspection, then to discharge its duty of care an authority having power to inspect is obliged to take reasonable steps to ascertain the existence of latent dangers which might reasonably be suspected to exist."

1. By analogy to this reasoning, counsel for the Barclay companies envisaged a duty of care, owed by the Council to oyster consumers, to take reasonable care to identify and to remedy sources of pollution at Wallis Lake and its tributaries. Adopting and adapting the terms used in Brodie, the Barclay companies asserted a duty on the part of the Council to take reasonable care that the exercise of or failure to exercise its powers to carry out works and repairs on sewerage installations did not create a foreseeable risk of harm to a class of persons (consumers of produce from the lake, or, more narrowly, consumers of oysters) which included Mr Ryan and the other applicants in the Federal Court. Two factors in particular were said to justify a duty in these terms. These were that (i) the Council was the only party with actual knowledge of the progressive deterioration of the sewerage infrastructure which imperilled the purity of the waters of Wallis Lake, and (ii) the Council had extensive statutory powers to prevent or to redress that deterioration and to mitigate the effects of any pollution.
2. The accuracy of these two observations may be accepted. However, the co‑existence of knowledge of a risk of harm and power to avert or to minimise that harm does not, without more, give rise to a duty of care at common law. The totality of the relationship between the parties, not merely the foresight and capacity to act on the part of one of them, is the proper basis upon which a duty of care may be recognised. Were it otherwise, any recipient of statutory powers to licence, supervise or compel conduct in a given field, would, upon gaining foresight of some relevant risk, owe a duty of care to those ultimately threatened by that risk to act to prevent or minimise it. As will appear, the common law should be particularly hesitant to recognise such a duty where the relevant authority is empowered to regulate conduct relating to or impacting on a risk‑laden field of endeavour which is populated by self-interested commercial actors who themselves possess some power to avert those risks.
3. The existence or otherwise of a common law duty of care allegedly owed by a statutory authority turns on a close examination of the terms, scope and purpose of the relevant statutory regime. The question is whether that regime erects or facilitates a relationship between the authority and a class of persons that, in all the circumstances, displays sufficient characteristics answering the criteria for intervention by the tort of negligence.

"The statutory scheme that formed the background to the activities of the present respondents was, relevantly, a scheme for the protection of children. It required the respondents to treat the interests of the children as paramount. Their professional or statutory responsibilities involved investigating and reporting upon, allegations that the children had suffered, and were under threat of, serious harm. It would be inconsistent with the proper and effective discharge of those responsibilities that they should be subjected to a legal duty, breach of which would sound in damages, to take care to protect persons who were suspected of being the sources of that harm."

1. However, contrary to submissions put on behalf of the Attorney-General for Western Australia (as an intervener in this Court), the discernment of an affirmative legislative intent that a common law duty exists, is not, and has never been, a necessary pre‑condition to the recognition of such a duty. This may be contrasted with the action for breach of statutory duty, the doctrinal basis of which is identified as legislative intention[92].
2. An evaluation of whether a relationship between a statutory authority and a class of persons imports a common law duty of care is necessarily a multi-faceted inquiry. Each of the salient features of the relationship must be considered. The focus of analysis is the relevant legislation and the positions occupied by the parties on the facts as found at trial[93]. It ordinarily will be necessary to consider the degree and nature of control exercised by the authority over the risk of harm that eventuated[94]; the degree of vulnerability of those who depend on the proper exercise by the authority of its powers[95]; and the consistency or otherwise of the asserted duty of care with the terms, scope and purpose of the relevant statute[96]. In particular categories of cases, some features will be of increased significance. For example, in cases of negligent misstatement, such as Tepko Pty Ltd v Water Board[97], reasonable reliance by the plaintiff on the defendant authority ordinarily will be a significant factor in ascertaining any relevant duty of care.
3. The factor of control is of fundamental importance in discerning a common law duty of care on the part of a public authority[98]. It assumes particular significance in this appeal. This is because a form of control over the relevant risk of harm, which, as exemplified by Agar v Hyde[99], is remote, in a legal and practical sense, does not suffice to found a duty of care.
4. In Brodie, the council exercised physical control over the condition of the roads which it was empowered by statute to maintain and which themselves constituted the direct source of harm to road users[100]. The council's measure of control over the safety of the person or property of citizens was "significant and exclusive"[101]. So, too, the fact of control over, and knowledge of, land or premises has been significant in identifying the duty of care owed to users of land or premises by a statutory authority which controls and manages that land or premises[102]. Again, in Pyrenees Shire Council v Day[103], the Shire held a significant and special measure of control over the safety from fire of persons and property at the relevant premises. That degree of control was the touchstone of the Shire's duty to safeguard others from the risk of fire in circumstances where the Shire had entered upon the exercise of its statutory powers of fire prevention and it alone among the relevant parties knew of, and was responsible for, the continued existence of the risk of fire[104]. It will be recalled that, in Pyrenees, the only other party with that knowledge was the former tenants. They had not communicated it to the subsequent tenants or adjoining occupiers, who were the relevant parties in this Court.

1. These claims also have fluctuated in the course of the litigation. By their re‑amended statement of claim dated 21 April 1998, Mr Ryan and the other applicants contended that the State, in its various manifestations, owed them a range of duties of care. The applicants asserted:

(i) a duty on the part of the Minister for Fisheries ("the Minister") at all material times on and after 13 January 1995 to determine forthwith (1) a New South Wales Shellfish Quality Assurance Program, pursuant to reg 12B of the Fisheries Management (Aquaculture) Regulation 1995 (NSW) ("the Management Regulation") to which further reference will be made; the requisite programme was to include relevant local shellfish quality assurance programmes, and (2) a programme to ensure that shellfish were taken from estuarine waters to be sold for human consumption only if the shellfish met the quality standards specified in or under the programme and those waters met suitable environmental standards;

(ii) duties on the part of the New South Wales Shellfish Quality Assurance Committee ("the State Committee"), which was formed by the Minister under reg 12C of the Management Regulation, to supervise the administration of any State quality assurance programme, to advise the Minister with respect to any such State or local programmes, and to develop and implement public health and environmental education programmes for aquaculture farmers, including Wallis Lake oyster farmers;

(iii) a duty on the part of the Wallis Lake Shellfish Quality Assurance Committee, which also was formed by the Minister under reg 12C, to establish and administer a local shellfish quality assurance programme for the Wallis Lake region;

(iv) a duty on the part of the EPA[110] to take steps to ensure that the Council did not pollute the Wallis Lake region by its sewage treatment and depot facilities and that private land owners or users of the waters of the Wallis Lake region did not pollute the region, and a duty on the EPA to monitor in conjunction with the Council the quality of the water and environment in the region;

(v) duties on the part of the Director-General of the New South Wales Department of Health ("the Director-General") or the Minister for Health to ensure that (1) purification plant operators processing oysters from the Wallis Lake region complied with the conditions of their permits; (2) purification plants operated in such a way as to ensure that any bacteria or virus was removed from oysters so processed; and (3) Wallis Lake oysters were not harvested, sold or supplied at a time or times when the region was polluted or likely to be polluted such that it was likely that the oysters were not fit for human consumption.

1. The re‑amended statement of claim asserted that each of these duties had been breached, and that the injury to the consumers was consequent upon those breaches.
2. The trial judge concluded that the State owed a duty of care to oyster consumers to take those steps that reasonably were open to it to minimise the risk of consumers contracting a viral infection from the oysters. This duty was said to arise from the "substantial managerial control" which Wilcox J found the State exercised over the Wallis Lake oyster industry[111]. The "substantial managerial control" was said to lie in the State's ownership of the lake, its grant of oyster leases, its administration of aquaculture permits, its supervision of the depuration process, its participation in the Wallis Lake Estuary Management Committee, and its statutory powers to mitigate pollution, to carry out inspections and investigations and to prohibit the harvesting of oysters[112]. The Court decided that the State's duty was "clearly breached" by its failure, "[l]ong before November 1996", either to ensure the making of a comprehensive sanitary survey or to close the Wallis Lake fishery[113].
3. A majority of the Full Court (Lee J and Kiefel J, Lindgren J dissenting) dismissed the State's appeal. Lee J held that the State owed the oyster consumers a duty of care to ensure that the powers it had created were exercised to reduce the risk of harm to those consumers[114]. His Honour said that the State breached this duty[115]:

"by reason of its failure to manage the waters of the Lake by taking steps to have sanitary surveys of oyster-growing waters undertaken and sources of pollution, or potential pollution, identified and rectified and to implement controls on the harvesting of oysters in conditions known to increase the risk of oyster contamination and, in particular, in failing to close the Lake fishery when those conditions occurred in 1996 and keep the fishery closed until circumstances existed that made it safe for the harvesting of oysters for sale to the public to resume".

1. Kiefel J posited a narrower duty, which she defined in relation to events immediately subsequent to the heavy rainfall of November 1996. Her Honour expressed the view that, immediately following that rainfall, the Minister was empowered by the Fisheries Management Act 1994 (NSW) ("the Fisheries Management Act") to prohibit the harvesting of oysters from the Wallis Lake region for a specified period. Her Honour concluded that the State "thereby came under a duty to exercise its powers and prohibit harvesting until the Minister could be assured of the likelihood of the oysters' fitness for consumption"[116]. The State's failure to do so, in Kiefel J's view, constituted a breach of that duty.
2. By notice of contention dated 16 November 2001, Mr Ryan and the other first respondents to the appeal now before this Court submit that the decision of the Full Court should be affirmed on grounds other than those relied upon by that Court. The notice contends that the State owed a duty to the consumers to take reasonable care to protect them from reasonably foreseeable risks of injury as a result of the consumption of oysters. A duty formulated in these terms is said to arise from (i) the State's ownership of Wallis Lake; (ii) its statutory powers of "control" over Wallis Lake and the Wallis Lake oyster industry; (iii) the "substantial managerial control" which Wilcox J found the State exercised over the Wallis Lake oyster industry; and (iv) the State's knowledge of the risk of harm to consumers of oysters taken from Wallis Lake. The State is said to have breached this duty of care by neither (a) taking steps to have sanitary surveys of oyster growing waters undertaken and sources of pollution or potential pollution identified and rectified; nor (b) implementing controls on the harvesting of oysters in conditions known to increase the risk of oyster contamination; nor (c) closing the Wallis Lake fishery when those conditions occurred in 1996 and keeping the fishery closed until circumstances existed that made it safe for the harvesting of oysters for sale to the public.
3. In argument before this Court, the evolution of the case against the State continued. Counsel for Mr Ryan described the State's duty of care in the following terms. It was said that the State had relevantly embarked upon one limb of what was necessarily a two-limbed approach to oyster safety. That is, the State had instituted a system of compulsory 36‑hour depuration of oysters prior to sale[117], but it had failed to require what it knew was a necessary precondition to the effectiveness of depuration, being the carrying out of sanitary surveys to detect and to remedy pollution in oyster growing areas. It was submitted that, having embarked upon the management of the oyster industry in the way that it had, the State came under a duty of care to carry out the sanitary surveys that it knew were necessary to effectuate the depuration process. Further, if, after having identified sources of pollution, the safety of a particular oyster growing area could not be assured, the State was said to come under a common law duty to close the relevant fishery until the problem could be remedied.

1. Through the medium of the EPA, the State[118] has powers under the Clean Waters Act to remove, disperse, destroy or mitigate pollution of waters (s 27), to direct the removal, dispersion, destruction or mitigation of water pollution (s 27A) and to carry out inspections and investigations of premises (s 29). Under cl 21 of the Clean Waters Regulations 1972 (NSW), the EPA may direct occupiers of premises to undertake measures to control or to prevent the discharge into waters of pollutants from those premises. Together, these provisions empowered the State itself to conduct regular sanitary surveys of oyster growing areas including those at Wallis Lake.
2. Further, the State could require oyster growers to cooperate in the carrying out of a sanitary survey, or could make oyster harvesting in a particular area conditional on the prior completion of a sanitary survey. This could be achieved either as a condition of an aquaculture lease or permit or as an element of a commercial aquaculture industry development plan.
3. Part 6 (ss 142‑191) of the Fisheries Management Act is headed "Aquaculture management". Division 3 (ss 163‑180) thereof is entitled "Leases of public water land for aquaculture". Section 163 empowers the Minister, on application or by auction, public tender or ballot, to lease an area of public water land for use for aquaculture[119]. A lease of that type vests in the lessee (i) the exclusive right during the currency of the lease to cultivate within, and to take from, the leased area the species of fish[120] specified in the lease, subject to the provisions of or made under the Fisheries Management Act and the provisions of the lease and (ii) the ownership of all fish specified in the lease that are within the leased area (s 164). An aquaculture lease may be renewed by the Minister (s 167). The Minister may require as a condition of granting or renewing a lease that the lessee have a survey of the area carried out to a standard approved by the Minister or may, by notice, require the lessee to have such a survey carried out within a specified period (s 169). Failure to comply with such a notice is a breach of a condition of the lease (s 169(4)). The Minister is empowered by s 169(6) to enter into arrangements with representatives of the commercial aquaculture industry for the payment of the cost of carrying out surveys under s 169.
4. Section 163(3) provides that an aquaculture lease must specify the species of fish authorised to be cultivated within the leased area, but that this "does not authorise the use of a lease without an aquaculture permit". Aquaculture permits are provided for in Div 2 (ss 144‑162) of Pt 6 of the statute. Section 144 proscribes the undertaking of aquaculture without an aquaculture permit. Applications for aquaculture permits are to be made to the Minister in the manner prescribed by s 145. Section 146 empowers the Minister to refuse to issue a permit on specified grounds. An aquaculture permit is relevantly subject to such conditions as are specified in the permit or as the Minister notifies to the permit holder while the permit is in force; those conditions may be varied or revoked by the Minister at any time (s 152). A permit holder is guilty of an offence if, without lawful excuse, a condition of the permit is contravened (s 152(3)). Section 156 provides that a permit holder must, if the regulations so require, pay to the Minister an annual contribution towards, among other things, the cost of monitoring the quality of the environment in which aquaculture is undertaken and the cost of testing the quality of the fish cultivated. Pursuant to s 160, the Minister may, by notice in writing to the permit holder, cancel or suspend a permit on a number of specified grounds including the contravention by the permit holder of a condition of the permit.

1. Section 189 of the Fisheries Management Act provides:

"(1) The Minister may, by a fishing closure under Part 2, prohibit during a specified period the taking of fish or marine vegetation cultivated under an aquaculture permit from the area to which the permit applies if satisfied:

(a) that the area is in such a condition that the taking of fish or marine vegetation from the area ought to be suspended; or

(b) that the fish or marine vegetation are, or are likely to be, unfit for human consumption.

(2) Any such fishing closure does not prevent the taking of fish or marine vegetation for any purpose authorised by the regulations or the fishing closure.

(3) This section does not limit the application of a fishing closure under Part 2 to the taking of fish or marine vegetation from an area subject to an aquaculture permit and to which the permit does not apply." (emphasis added)

1. Part 2 (ss 8‑40) is headed "General fisheries management". Division 1 thereof provides for fishing closures. Section 8 states:

"(1) The Minister may from time to time, by notification, prohibit, absolutely or conditionally, the taking of fish, or of a specified class of fish, from any waters or from specified waters.

(2) Any such prohibition is called a fishing closure."

Read in isolation, s 8 does not, in terms, stipulate that ministerial satisfaction is a pre‑condition to the exercise of the power which the provision confers. However, the effect of s 8 in the present context is to give the force of law to action taken by the Minister under s 189. That latter provision pivots on the existence of ministerial satisfaction of either of the circumstances specified in sub‑par (a) or sub‑par (b) of s 189(1). Where that satisfaction exists, the discretion to prohibit the taking of fish is enlivened and the Minister's decision thereunder becomes, by virtue of s 8, a "fishing closure" enforceable under Div 1 of Pt 2 of the Fisheries Management Act.

1. Section 9 of that statute provides that notification of a fishing closure is to be published in the Gazette or, if the Minister considers that the closure is urgently required, in the local media or by notice in a prominent place adjacent to the applicable waters. The closure remains in force for the period (not exceeding five years) specified in the notification (s 10). It may be amended or revoked by the Minister (s 11). A person who takes fish in contravention of a fishing closure is guilty of an offence (s 14).
2. At the time of the contamination at Wallis Lake, Pt 4 (ss 44‑56) of the Food Act 1989 (NSW) ("the Food Act") was headed "Particular powers of the Director-General". Section 45(1)(b) thereof conferred power on the Director-General of Health, by order, to "prohibit the cultivation, taking, harvesting or obtaining, from an area specified in the order, of any food or of any food of a class or description so specified". Section 44 provided that any such order could "be made only when the Director-General has reasonable grounds to believe that the making of one or more such orders is necessary in order to prevent or mitigate a serious danger to public health". Successive provisions regulated the manner of making such orders (s 46), conferred a right of appeal to the District Court against an order (ss 47, 48), and rendered any failure to comply with an order a criminal offence (s 49).
3. Mr Ryan and the other applicants in the Federal Court did not, in terms, plead an independent common law duty on the part of the Minister to prohibit under s 189 of the Fisheries Management Act oyster farming from Wallis Lake during the period of contamination. They did plead in par 47 of their re‑amended statement of claim, however, that "but for" the negligence said to have occurred by virtue of the breaches of duties (i), (ii) and (iii) set out at the beginning of Pt B of these reasons, the Minister "would have" exercised his powers under s 189 to prohibit oyster farming during the period of contamination of Wallis Lake. The assumption appeared to be that, if the quality assurance programmes said to be required by those duties had properly been implemented by November 1996, they would have required the Minister, in the circumstances then pertaining, to close the fishery.
4. Notwithstanding the absence of a pleading in those terms, a duty to close the Wallis Lake fishery under s 189 formed part of the duty held to exist by the primary judge and by Lee J in the Full Court. Further, the power to close the fishery appeared to comprise the entire content of the duty of care identified by Kiefel J in the Full Court.

1. The Barclay companies concede that they owed a duty of care to their consumers, including Mr Ryan, to take reasonable care to ensure that the oysters they harvested and supplied were safe for human consumption. The immediate issue before this Court is whether the companies breached that duty. This requires consideration of the circumstances disclosed by the evidence before the primary judge.
2. At trial, Wilcox J concluded that, in selling without warning oysters grown in waters known to be subject to possible undetectable viral contamination, the Barclay companies had breached their duty of care[126]. His Honour suggested that the proper discharge of the duty would have involved procuring, or attempting to procure, governmental agreement to conduct a sanitary survey of the relevant area[127].
3. By majority, the Full Court (Lee J and Kiefel J, Lindgren J dissenting) upheld the primary judge's conclusion that the Barclay companies were liable in negligence to Mr Ryan. Lee J described the duty of care owed by the companies as being to refrain from harvesting and selling oysters from Wallis Lake when conditions had arisen that to the knowledge of the Barclay companies increased the risk of the oysters being contaminated. In his Honour's view, this duty was breached by the sale to the public of oysters before the Barclay companies "had taken the steps that were necessary to show it was safe to resume the harvesting and sale of oysters"[128]. Kiefel J defined the duty and its breach in similar terms. Her Honour held that the companies "should not have supplied oysters for sale until a sufficient period had elapsed by which the risk of contamination could be regarded as acceptable or tests sufficiently indicated that to be the case"[129]. (emphasis added)
4. The duty of the Barclay companies did not extend to ensuring the safety of oysters in all circumstances[130]. In Wyong Shire Council v Shirt, Mason J (with whom Stephen J and Aickin J agreed) stated[131]:

"In deciding whether there has been a breach of the duty of care the tribunal of fact must first ask itself whether a reasonable man in the defendant's position would have foreseen that his conduct involved a risk of injury to the plaintiff or to a class of persons including the plaintiff. If the answer be in the affirmative, it is then for the tribunal of fact to determine what a reasonable man would do by way of response to the risk. The perception of the reasonable man's response calls for a consideration of the magnitude of the risk and the degree of the probability of its occurrence, along with the expense, difficulty and inconvenience of taking alleviating action and any other conflicting responsibilities which the defendant may have."

Neither Lee J nor Kiefel J expressed themselves as approaching their task by the sequential reasoning process which Wyong Shire Council mandates.

1. An analysis of the competing considerations referred to in Wyong Shire Council is impeded, not assisted, by formulating the relevant duty of care in terms of its breach, which was the approach that the majority in the Full Court appeared to adopt. The use by Kiefel J in the passage quoted in [189] above of the words "sufficient" and "could be regarded" does not deny the cogency of the submission by the Barclay companies that duty was identified in terms of breach.
2. A duty of care that is formulated retrospectively as an obligation purely to avoid the particular act or omission said to have caused loss, or to avert the particular harm that in fact eventuated, is of its nature likely to obscure the proper inquiry as to breach[132]. That inquiry involves identifying, with some precision, what a reasonable person in the position of the defendant would do by way of response to the reasonably foreseeable risk. As Isaacs ACJ observed in 1924, "[n]o conclusion of negligence can be arrived at until, first, the mind conceives affirmatively what should have been done"[133]. The trial judge and the majority of the Full Court in the present case failed to identify with the necessary precision, by reference to considerations of the nature of those indicated in Wyong Shire Council, the reasonable response to the risk of harm that existed. In so failing, their Honours fell into an error of law. There is no serious dispute as to the facts to which the law is to be applied. Thus, it is appropriate for this Court to resolve the matter. For the reasons that follow, the proper application of principle requires a conclusion different to that reached in the Federal Court.
3. The risk of injury which eventuated in this case was not far-fetched or fanciful; it was real and was therefore foreseeable[134]. The Barclay companies knew that viral contamination of oysters could result from human faecal pollution of the waters in which oysters are cultivated. The companies knew that depuration alone was an inadequate guarantee of oyster safety. They were aware that there existed, in the vicinity of Wallis Lake, septic tanks, stormwater drains and other facilities which, if defective, could cause faecal pollution of the waters. There was some dispute about whether or not the Barclay companies had actual knowledge that any of those facilities were defective, or actual knowledge about the existence of specific pollution problems. Nonetheless, it was reasonably foreseeable that the conduct of the business of the Barclay companies involved a risk of injury to oyster consumers.

1. Mr Ryan's appeal (No S259/2001) should be dismissed with costs.
2. The State's appeal (No S261/2001) should be allowed with costs.
3. In the appeal by the Barclay companies (No S258/2001), the appeal by Barclay Distributors should be allowed with costs and that by Barclay Oysters allowed in so far as it concerns the issue of negligence but with no order as to costs.
4. The parties to each of these appeals should have 28 days within which to file draft minutes of consequential orders to be made by this Court in respect of the orders (including costs orders) made by the Full Court. In default of agreement between the parties to any of the appeals as to the form of the draft minutes for that appeal, each party is to file within that 28 day period its draft with short written submissions in support, indicating how the drafts of the parties differ.
5. KIRBY J. These appeals come from the Full Court of the Federal Court of Australia[135]. The most important question that they present concerns the principles governing the common law duty in negligence, both of a State of the Commonwealth and of a local government authority, where each is said to be liable for failing to exercise powers conferred upon it by legislation.
6. Once again this Court is required to consider whether, in the particular circumstances of the case, the law entitles a person who can prove damage to bring home the consequences not only to any private organisation that owed him a duty of care which it breached but also to public authorities whose breaches are said to lie in their failure to properly discharge their statutory powers[136].
7. One day this Court may express a universal principle to be applied in determining such cases. Even if a settled principle cannot be fashioned, it would certainly be desirable for the Court to identify a universal methodology or approach, to guide the countless judges, legal practitioners, litigants, insurance companies and ordinary citizens in resolving contested issues about the existence or absence of a duty of care, the breach of which will give rise to a cause of action enforceable under the common law tort of negligence[137]. Courts such as this should recall the prayer of Ajax[138]:

It is a supplication that must have occurred to many who have considered recent decisions on the subject of the duty of care: "[S]ave us from this fog and give us a clear sky, so that we can use our eyes"[139].

1. The differing approaches to the duty of care issue adopted in Perre v Apand Pty Ltd[140], a case of economic loss, have been described as an instance of "doctrinal chaos"[141]. Such differences concerning claims in negligence against public authorities impose special burdens in finding, understanding and applying the law. These burdens are intolerable. This fact is illustrated by the present case. The unfortunate judges of the Federal Court (including Wilcox J, the primary judge[142]) were obliged to spend many hours (and many pages of their reasons) demonstrating their consideration of the differing approaches adopted in this Court to the questions that had to be solved. Anyone in doubt about these propositions can read the Federal Court's reasons[143].
2. Only one unarguable principle emerges from the earlier decisions, reflected in the Federal Court's analysis. It is the self-evident one that any duty of a public authority at common law must be compatible with the legislative powers conferred, and duties imposed, on that authority[144]. It must conform to the apparent purpose of the legislature relating to the authority carrying out its duties according to statute[145]. As Lindgren J said in the Federal Court, the search for what the law expects must commence "with a close examination of the relevant legislation"[146]. As Kiefel J expressed it, "the principal focus must be upon the statutes which confer power on those entities"[147].
3. In deciding whether a breach of a statutory duty gives rise to a civil remedy for damages at the suit of an individual, Hayne J has pointed out, correctly in my view, that a court "is not assisted by references to the 'intention' of the legislature"[148]. Nor is a court entitled simply to give effect to its own ideas of what is desirable, attributing those ideas to the legislature's "intention"[149]. The same may be accepted as true in relation to the suggestion that a failure by a governmental authority to exercise its powers constituted negligence. However, once a decision-maker passes beyond these elementary principles of agreed doctrine, he or she enters a realm of great uncertainty in which there is no principle that currently commands universal assent, unless it be that such a principle is not presently discoverable[150].

1. The facts are set out in the reasons of the other members of this Court[151]. In broad outline they are simple. Early in 1997, a number of consumers, including Mr Grant Ryan, were diagnosed as suffering from hepatitis A. This is a serious, and potentially fatal, viral infection. Its aetiology is commonly attributed to contact with human faeces. In the case of Mr Ryan and many other persons, the outbreak of this condition was traced to the consumption of oysters harvested from Wallis Lake in New South Wales. The finding about the source of the infection is not disputed; nor that the cause was the pollution of Wallis Lake by human faecal contamination.
2. Mr Ryan, on his own behalf and on behalf of an expanded group of consumers in a like position whom he represented, commenced proceedings in the Federal Court claiming damages. He named three groups of defendants: the State of New South Wales ("the State"), the Great Lakes Council ("the Council"), a local government authority now deriving its existence and general powers from the Local Government Act 1993 (NSW) ("the LGA") and the two Graham Barclay companies responsible for the growing and harvesting of the oysters and for their distribution ("the Barclay companies"). Mr Ryan's proceedings were brought as a representative action[152]. Wallis Lake, where the Barclay companies operated, was within the area committed to the Council under the LGA.
3. Mr Ryan brought a claim against the Barclay company responsible for farming and harvesting the oysters (Graham Barclay Oysters Pty Ltd) ("Barclay Oysters") under the Trade Practices Act 1974 (Cth) ("the TPA"). Although, in the Full Court, there were appeals and cross-appeals in relation to the claims under the TPA, the Full Court confirmed the primary judge's conclusions with respect to the TPA claims. What happened is explained in the joint reasons of Gummow and Hayne JJ ("the joint reasons")[153]. The judgment against Barclay Oysters under the TPA was reduced fractionally for an error found to have been made in its computation[154]. However, this is not a matter that has concerned this Court.
4. Mr Ryan brought claims of common law negligence against all the parties. In his claims against the State, Mr Ryan relied on a number of State statutes and regulations affording powers to various officers or agencies of the State to take steps for the control of the production of oysters in State waters, such as Wallis Lake. The relevant provisions of these statutes appear in other reasons[155]. Likewise, powers specific to the protection of the environment, including the water environment such as Wallis Lake, were conferred by and under State legislation on local government authorities, such as the Council. These provisions too are set out in other reasons[156]. I will not repeat any of these details.

1. Four issues arise, expressed in terms of the suggested errors of the Full Court:

(1) Are the provisions of the TPA such as, in effect, to exclude the concurrent operation of the common law of negligence and therefore to confine Mr Ryan, as a matter of law, to his entitlements under the TPA against Barclay Oysters, which is uncontested in this Court?

(2) If not, in respect of common law negligence, did the State and/or the Council owe a duty of care to consumers such as Mr Ryan with respect to the contamination of the subject oysters (there was no contest that the Barclay companies owed him a duty of care)?

(3) If so (and in any event, in the case of the Barclay companies) did Mr Ryan establish a breach of the common law duty of care causing his damage so as to entitle him to recover damages against any or all of the State, the Council and the Barclay companies?

(4) In any case, did the primary judge err in law in including in his orders an order, in the form of order 2, declaring that Mr Ryan was entitled to succeed against the parties held to be liable to him?

1. In Crimmins v Stevedoring Industry Finance Committee[164] I pointed out that the first question to be decided, in considering whether the provisions of legislation are compatible with the imposition by the common law of a duty of care on individuals, is the ascertainment of whether the two forms of legal liability can co-exist. This is a problem that can arise in any area of the law, including cases having nothing whatever to do with claims for damages in negligence[165]. If, for example, it is clear that a legislature, with full constitutional powers to do so, has, in effect, completely and exhaustively covered the applicable subject matter of legal regulation, it will not be competent for a court to add to the legislative design additional and inconsistent legal duties which the court attributes to general principles of the common law. In such a case, the statutory provisions will expel the common law's capacity to so prescribe.
2. During argument of the appeal before this Court, a question was raised as to whether the express provision of the TPA with respect to liability to consumers for defective products (such as the subject oysters) constituted such a coverage of the subject field of law as to prevent development of the common law designed to impose other and different legal obligations on other and different parties, not the subject of such federal regulation.
3. In the past, it has been accepted that, notwithstanding the enactment of provisions in the TPA, important aspects of common law doctrine remain applicable and effective. An example is the interaction of the TPA with the common law rule against the restraint of trade[166]. In other areas of the law involving the application of the TPA, questions have arisen as to whether the TPA has covered the relevant field of legal regulation, leaving no room for the application in that field of pre-existing rules of the common law or of equity[167]. The question whether the common law can exist side by side with provisions of the TPA is one that has been noted by this Court in earlier decisions. Analogous issues have also received attention in the context of anti-trust law in the United States of America[168].
4. Because the issue of statutory "pre-emption" was not expressly raised by any party as a fundamental ground of objection to Mr Ryan's claims based upon the common law, it is appropriate to proceed on the assumption that the claims can exist concurrently. I am content to do this. A claimant could not, of course, recover twice but would be obliged to elect before enforcing judgment[169].

1. Search for a methodology: Actions at common law for negligence probably still constitute the largest segment of civil litigation before Australian courts. It is therefore natural, and efficient if it be possible, for the law to afford a methodology or approach to such cases where liability is in dispute. Adopting a methodology encourages consistency and the avoidance of legal error.
2. There are certain "standard questions"[170] that dissect the composite notion of common law liability in negligence. Relevantly, those questions analyse the concept in terms of: (1) the duty of care; (2) the scope of the duty; (3) the breach; and (4) the causation of damage. Although these issues are commonly considered separately, it has been pointed out many times that "each element can be defined only in terms of the others"[171] and, for example, that "the actual nature of the damage suffered is relevant to the existence and extent of any duty to avoid or prevent it"[172]. These words teach an important lesson. Excessive analysis and undue intellectual subdivision of what is basically a unitary concept can lead a decision-maker into over-sophisticated elaboration of a notion that is, at its heart, a reflection of practicality and common sense. Long ago and far away, Oliver Wendell Holmes Jr said, correctly, that "the general foundation of legal liability in blameworthiness, as determined by the existing average standards of the community, should always be kept in mind"[173]. Although that was said years before Lord Atkin wrote his speech in Donoghue v Stevenson[174], it is reflected in what his Lordship said there[175]:

"The liability for negligence … is no doubt based upon a general public sentiment of moral wrongdoing for which the offender must pay. But acts or omissions which any moral code would censure cannot in a practical world be treated so as to give a right to every person injured by them to demand relief. In this way rules of law arise which limit the range of complainants and the extent of their remedy."

1. The Caparo three-stage test: Whilst Lord Atkin in Donoghue v Stevenson, building on earlier judicial attempts, propounded a unifying concept for liability in negligence at common law, and specifically for the circumstances giving rise to a legally enforceable duty of care, the defect in his analysis and in its acceptance in later cases as a "general unifying proposition"[176] or "statement of principle"[177] is the generality, even circularity, of the touchstone for defining the "neighbour" relationship[178]. The decision in Donoghue v Stevenson inevitably gave rise to attempted refinement, so as to retain the advantages of a unifying concept but to flesh out the detail concerning the manner of its application.
2. A major attempt in that direction was made in England in Anns v Merton London Borough Council[179]. Subsequently, the two-stage test expressed in that case was expanded by the House of Lords in Caparo Industries Plc v Dickman[180]. That decision was interpreted as establishing a settled approach. In order to decide whether a legal duty of care existed, the decision-maker was obliged to ask three questions. These were: (1) whether it was reasonably foreseeable to the alleged tortfeasor that the particular conduct or omission would be likely to cause harm to a person such as the claimant; (2) whether between that tortfeasor and the claimant a relationship existed that could be characterised as one of "proximity" or "neighbourhood"; and (3) if so, whether it was fair, just and reasonable that the law should impose a duty of a given scope upon that tortfeasor for the benefit of that person.
3. The Caparo test, sometimes worded in slightly different ways, continues to be applied in England. Variants of it are applied in other Commonwealth countries. As recently as 2001, in a unanimous decision, the Supreme Court of Canada in Cooper v Hobart[181] affirmed its adherence to an approach adapted from Anns via earlier Canadian decisions[182]. Correctly in my opinion, informed observers have described the Canadian approach as looking "remarkably familiar to the 'classic' incremental approach re-adopted by the House of Lords in cases such as … Caparo"[183].
4. Competing Australian approaches: Whilst these developments were occurring in other common law countries, Australian courts, led by this Court, continued with their attempts to propound alternative and different tests for establishing the existence of a duty of care. It was obvious that "foreseeability" alone was insufficient to give rise to the potentially onerous obligations of a legal duty to act. Hence the experiments with other concepts such as "proximity"[184] and "reliance" - including the fiction of "general reliance"[185].

(1) The adoption in this country of the three-stage test proposed in England in Caparo. This is the approach that I have consistently adopted, in Pyrenees Shire Council v Day[187]; Romeo v Conservation Commission (NT)[188]; Perre v Apand Pty Ltd[189]; Crimmins v Stevedoring Industry Finance Committee[190]; Brodie v Singleton Shire Council[191], and other cases. The approach has attracted academic favour[192]; but alas, no judicial support where it mattered; and

(2) The adoption of a notion that a range of other factors, sometimes called "salient factors", must be considered in order to determine the existence of a duty of care in a particular case[193]. A cornucopia of verbal riches has been deployed to identify what, in given proceedings, these "salient features" will be. Some of them appear in the Court's decision in Perre v Apand Pty Ltd[194]. Many of them are helpfully collected by Callinan J in these appeals ("vulnerability, power, control, generality or particularity of the class, the resources of, and demands upon the authority", the "core, or … non-core" functions or relation to "a matter of policy or executive action" and so on)[195].

1. Choosing the new approach: In 2001 in Sullivan v Moody[196] an appeal in which I did not participate, five members of this Court, in a unanimous joint opinion, rejected the three-stage test for a duty of care propounded in Caparo. Hints that this outcome was likely had been given in earlier decisions in which individual members of the Court had declined to embrace the Caparo approach[197]. It was clear from these earlier decisions, and clearer still from Sullivan[198], that the members of this Court were concerned that the frank acknowledgment, in the third stage of the Caparo approach, of the need to consider policy questions, could divert the courts (and decision-makers applying the law) from the clear application of discoverable legal norms into an evaluation of policy that is not properly the business of courts. This concern is a natural one and I understand it. Even in England it has led to the insistence by a number of the Law Lords upon the fact that they are concerned in this regard only with questions of legal principle or prescribed legal policy[199]. The flaw in the Caparo approach, discerned in the joint reasons in Sullivan, was that the question of liability might be "reduced to a discretionary judgment based upon a sense of what is fair, and just and reasonable as an outcome in the particular case"[200]. That, it was concluded, would introduce into judicial decision-making an unacceptable unpredictability based on an inappropriate methodology.
2. In the face of this explicit disapproval of the Caparo approach, my duty is to conform to the opinion that the majority of this Court has stated. This is not an area of the law where the interpretation of the Constitution imposes special obligations upon individual Justices to give effect to their opinions about the requirements of the basic law. Nevertheless, I relinquish my adherence to the Caparo approach with reluctance. It is, after all, the methodology adopted in the major common law legal systems with which Australian judges are familiar[201]. It at least provides a methodology or approach for the determination of a complex question, which a search for the so-called "salient features" of a case does not. Sullivan has been criticised, correctly in my respectful opinion, as involving "serious error"[202]. This Court has been taken to task for its repudiation of the idea that "policy" has a dominant role to play in the determination of duty issues. It has been castigated for embracing "a chimera"[203]. With the utmost respect, I agree with the comment made that in Sullivan this Court[204]:

"has acted without due care in abandoning [the Caparo] test. It is difficult to conceive how duty issues can properly be analysed without resort to each of the three elements in the test. It is clear that courts must look for factors which indicate a minimum ability to avoid the causation of damage and for factors which identify particular persons as being appropriately placed to take care so as to avoid such damage. Foreseeability and proximity, respectively, serve these functions. But the decision whether or not to impose a duty will be, ultimately, a normative one - a question of legal policy, if you like. For this reason, Caparo … is likely to remain an irresistible force in the law of negligence."

1. The resulting test: In somewhat different circumstances, Dixon J stated "for a mind that denies the correctness of reasoning" leading to a court's authority, it is "neither safe nor useful … to proceed to expound its meaning and implications"[205]. I share that feeling in this case. However, in order to provide some guidance in eliciting the test for establishing the existence of a duty of care, I must do my best in the situation that has now arisen.
2. The development of an approach, hinted at by me in Pyrenees[206], may provide an answer. The statements I made there acknowledged that the verbal attempts at identifying particular criteria for distinguishing cases where a duty of care existed (and where it did not) had failed; that candid policy evaluation was uncongenial to Australian judges or considered inappropriate; and that liability should therefore be imposed where it was judged that a reasonable person in the defendant's position could have avoided damage by exercising reasonable care and was in such a relationship to the plaintiff that he or she ought to have acted to do so[207]. Despite its overt circularity, this formulation might at least offer a return to the substance of Lord Atkin's speech in Donoghue v Stevenson. It might afford a broad formula that poses a factual (or jury) question and avoids the chaos into which other attempted formulae have lately led the law.
3. In similar terms, Priestley JA in Avenhouse v Hornsby Shire Council[208] was moved to remark in the New South Wales Court of Appeal:

"Courts … decide, in case after case, whether or not a duty of care exists in new situations. Consideration of all the cases of authority to date leads me to the view that the position in Australia … has returned to (or recognised the continuing applicability of) what it was immediately after the decision in Donoghue v Stevenson; that is, that the courts make decisions by first asking the question 'is the relationship between plaintiff and defendant in the instant case so close that a duty arose?' and then answering 'yes' or 'no' in light of the court's own experience-based judgment."

1. The difficulty with this formulation is that the reference in it to the relationship of the parties as one "so close that a duty arose" could quite easily slip back into the discredited notion that "proximity", alone, is a sufficient criterion for the assignment of a legal duty. However, so long as the "closeness" of the relationship contemplated is not confined to physical closeness, I see no great difficulty now (and some advantage) in leaving the features of the "relationship" of "neighbourhood" undefined and simply asking whether, in all the circumstances, it is such as to make it "reasonable to impose upon the one a duty of care to the other"[209]. This is always the ultimate question that must be answered in all cases of a disputed duty of care in negligence. Somehow in the end accumulated facts must be turned into an "ought".
2. In answering the "ultimate question", in a case involving the alleged neglect of a statutory authority to utilise the statutory powers that it undoubtedly enjoys, it will obviously be essential to analyse those powers carefully. It will be necessary to attempt to derive from the language and structure of the applicable legislation, viewed as a whole, a conclusion as to whether, in the particular case, the power conferred on the authority had been converted to the obligations of a duty. The reference to the "particular case" will, in turn, invoke a consideration of the multitude of special features of the relationship between the parties that I take it the multi-factorial or "salient features" approach requires. There is an irony that I would not wish to see overlooked. The course of the legal history followed in Anns and Caparo was actually initiated a few years earlier by the remarks of Lord Denning MR in Dutton v Bognor Regis Urban District Council[210]. In that case, Lord Denning suggested that the basis of the Council's liability lay in "control". This was a notion said by his Lordship to lie somewhere between "power" and "duty". Although that explanation was rejected by Lord Wilberforce in Anns[211], it is to be noticed how the concept of "control" on the part of a statutory authority is now re-emerging as crucial in this area of legal discourse[212].
3. Perhaps this is the ultimate lesson for legal theory in the attempted conceptualisation of the law of negligence and the expression of a universal formula for the existence, or absence, of a legal duty of care on the part of one person to another. The search for such a simple formula may indeed be a "will-o'-the wisp"[213]. It may send those who pursue it around in never-ending circles that ultimately bring the traveller back to the very point at which the journey began. Thus we seem to have returned to the fundamental test for imposing a duty of care, which arguably explains all the attempts made so far. That is, a duty of care will be imposed when it is reasonable in all the circumstances to do so. That is the test that Gummow J and I adopted in our joint reasons in the recent decision in Tame v New South Wales[214], decided after Sullivan. Even if the approach of the other members of the Court in that case does not do so explicitly, it is obvious that the "touchstone"[215] of reasonableness is fundamental to the way in which they determined the existence or otherwise of a duty of care[216]. So after 70 years the judicial wheel has, it seems, come full circle. In this way only is Ajax's prayer answered[217].

1. The duty of the State: In the already extended reasons in these appeals, I do not wish to repeat the features of the legislation and factual circumstances that are relevant to the determination of whether the State and the Council owed a duty of care to Mr Ryan. I have already acknowledged the important advantages that the primary judge enjoyed in considering all of the material. So far as the State is concerned, I am conscious of the fact that the primary judge, and the majority in the Full Court, concluded that a proper consideration of the applicable legislation, together with the factual evidence, imposed a duty of care on the State as the lessor of the oyster leases in Wallis Lake and the ultimate manager of fisheries (including oyster farming) in the State.
2. However, alike with other members of this Court[218] and for generally similar reasons, I have concluded that the State did not owe a duty of care to the ultimate consumers of oysters, such as Mr Ryan, to exercise its powers by and under legislation, in the ways propounded so as to prevent the contamination of the oysters that ultimately infected Mr Ryan and his co-plaintiffs. Once one approaches the matter in the way now suggested, it is difficult to draw from all of the circumstances a conclusion that the common law imposed legal liability on the State with respect to every person, such as Mr Ryan, for the failure of the State to implement the health and protective measures such as are contained in the applicable legislation.
3. Subject to any relevant substantive exemptions[219] or procedural protections[220], I agree with the joint reasons that it is not necessary, in order to construct a claim of common law negligence against a governmental entity or public authority in reliance upon that authority's failure to exercise powers conferred upon it by statute, for the claimant to prove that the statute evinced a specific purpose that an action at common law was to be included as one of the means of enforcing the statutory purpose. No such rule has hitherto been required by the common law. Where created as a distinct legal entity, a governmental body or public authority, like any other legal or natural person, must comply with the law. This includes the common law of negligence where it remains applicable.
4. When the two substantive claims against the State, into which the case of Mr Ryan ultimately evolved, are examined, namely failure to conduct sanitary surveys and failure to close the Wallis Lake fisheries at the relevant time, the problem of recognising the suggested duty of care on the part of the State is plain. The State Parliament had decided on a system of industry-funded self-regulation or co-regulation. In that context, and in the light of the level of the State's proved knowledge of the risks involved, the postulation of State intervention to conduct sanitary surveys in respect of Wallis Lake appears inconsistent with statute and unreasonable. In the same context, the suggestion that the State owed a duty, enforceable by the tort of negligence, to protect consumers such as Mr Ryan by closing down the Wallis Lake oyster industry for an unspecified time appears completely unreasonable and unrealistic. There was no actual knowledge of the State of a serious risk of infection. There had never been a previous case of infection traced to Wallis Lake oysters, although oysters had been farmed and harvested there for decades. The State and its agencies were not in control of the oysters or their manner of harvesting. In such circumstances, and in the context of the newly introduced form of industry self-regulation, such intervention by the agencies of the State before Mr Ryan became infected would, I believe, have been regarded, rightly, as an over-reaction and unnecessarily intrusive. I agree in this respect with the joint reasons[221].

1. The Barclay companies did not contest that they owed a duty of care to Mr Ryan and his co-plaintiffs. They could hardly do so following Donoghue v Stevenson. However, those companies submitted that no breach of their duty of care had been proved.
2. In judging the issue of breach, it is obviously necessary to relate it to the precise scope of the duty owed. Each of the Barclay companies was in a direct or indirect relationship with the ultimate consumers of the oysters. Those consumers were vulnerable, in the sense that they were dependent on the Barclay companies and would rarely, if ever, conduct tests of their own on the safety of oysters sold to them for consumption. Each Barclay company therefore had a specific duty, apart from statute, to ensure, so far as was reasonably practicable, the safety of the oysters offered to the market. It was not an absolute duty, as an insurer. But it was a high duty because of the serious (even potentially fatal) consequences of infection by needless exposure of the oysters to waterborne viruses, such as hepatitis A.
3. The issue before this Court is whether error has been shown in the decision of the majority in the Full Court, in refusing to disturb the primary judge's conclusion that a breach of the conceded duty had been proved. Mr Barclay, who spoke for both companies, acknowledged in evidence that he was aware at the relevant time of the existence of potential sources of viral pollution in Wallis Lake. He knew that depuration was inadequate to ensure the removal of such viruses and that flesh testing would not necessarily detect them. The primary judge had accepted that absolute assurance that the oysters were free of the hepatitis A virus was neither possible nor reasonable to expect. It was in these circumstances that the primary judge correctly focussed his attention, for the most part, upon what "significant contribution to risk reduction"[223] the Barclay companies could have instituted.
4. With the majority judges in the Full Court[224] and the joint reasons in this Court I would reject the hypothesis that the Barclay companies were negligent in failing to provide a warning to consumers of the risk that their oysters might have been contaminated. In particular cases, warnings can and do play an important part in the discharge of a duty of care[225]. However, the proposition that such a warning should have been provided with the subject oysters is unrealistic.

1. A comment is made in the joint reasons that may be read as critical of the action of the primary judge in providing an order in the form of a declaration of legal right that Mr Ryan was entitled to succeed against named parties "in respect of that portion of his representative claim that alleges negligence, but only on behalf of those group members who proved damage has been suffered by them"[231].
2. No objection appears to have been raised by any party at trial, or in the Full Court, to the making, or form, of that order. For all that this Court knows, the order may have followed the preparation of draft minutes of orders submitted by the parties, as is the usual course and the course contemplated by this Court's own orders in disposing of these appeals.
3. The making of the order is not a question raised by the appeals to this Court. I see no reason why this Court should initiate an objection of its own. Because it was not an issue, the point was not the subject of detailed written or oral submissions. At most, the question could have arisen in certain contingencies in settling any final orders of this Court. However, it would not arise in the disposition favoured by the joint reasons in the course of which the criticism is mentioned. I am far from convinced that it was beyond power, or "inappropriate"[232], for the primary judge to provide by his order as he did.
4. Under the Federal Court of Australia Act 1976 (Cth), that Court is constituted as a superior court of record and a court of law and equity[233]. It has national jurisdiction in a large number of matters, some of them with novel public interest features. As this case illustrates, the Federal Court enjoys specific and additional statutory powers to decide representative proceedings[234]. By s 33Z(1), which relates to the powers of the Federal Court to give judgment in representative proceedings, it is provided that (with emphasis added):

"The Court may, in determining a matter in a representative proceeding, do any one or more of the following:

(e) make an award of damages for group members, sub-group members or individual group members …

(f) award damages in an aggregate amount without specifying amounts awarded in respect of individual group members;

(g) make such other order as the Court thinks fit."

1. From these provisions, it is clear that the Parliament intended to arm the Federal Court with a wide and flexible armoury of powers, capable of being adapted to the particular needs and novel circumstances of representative proceedings and any matter in such proceedings. Representative proceedings are not traditional litigation; nor should they be subjected to all of the requirements of such litigation. To confine the grant of such a statutory power is incompatible with the oft-repeated statements in this Court concerning the construction of grants of such powers to superior courts[235]. In particular, it is inappropriate to impose upon such grants of power strictures derived from earlier times and traditional powers in litigation between individual parties.
2. Where the Federal Court is engaged, as it was here, in novel proceedings, this Court, in my view, should refrain from imposing limitations that are uncalled for[236]. The only authority cited to support the criticism of the primary judge's order relates to proceedings that have nothing to do with representative proceedings. For my own part, I can see no good reason why, in disposing efficiently of potentially complex representative proceedings, declarations of legal right as to a particular "matter" in the proceedings might not be appropriate at an interlocutory stage in order to clear away a part of the proceedings that has been finally decided[237]. But whether that is right or wrong, there is no reason why this Court should volunteer its opinion on the subject which, until properly challenged in this Court and necessary for decision, belongs to the procedural powers of the Federal Court as conferred by special statutory provision.

1. In relation to Mr Ryan's appeal (No S259/2001) and the State's appeal (No S261/2001), I agree in the orders proposed by Gummow and Hayne JJ, including the provision of time in which the parties may file draft minutes of consequential orders.
2. The appeal of the Barclay companies (No S258/2001) should be dismissed with costs.
3. CALLINAN J. The principal question which these appeals raise is whether the conferral of various statutory powers to regulate uses of land and waters, creates duties of care, in respect of the non-exercise or breach of which, affected persons may sue: in short, in what circumstances are statutory powers and functions to be regarded as duties?

Oysters are cultivated and thrive in Wallis Lake, which lies north of the Hunter River in New South Wales. There, holders of permits cultivate and harvest oysters from aquaculture leases granted by the State of New South Wales ("the State"). When heavy rain falls in the catchment of the lake run-off increases, and with it does the potential for pollution of waters and marine life growing in them, including oysters. These crustaceans, which daily ordinarily ingest and expel large quantities of water are particularly susceptible to contamination by faecal matter which may be carried by run-off into lakes and streams. This is so because changing conditions of temperature and salinity may reduce the creature's capacity to excrete contaminated water. Accordingly, harvesting is customarily suspended during, or for a relatively short period after rain. A question arises in this case as to the appropriate duration of the suspension of harvesting. One consequence of the contamination of oysters is that they may become a source of Hepatitis A which is a highly infectious disease. It can survive for long periods in marine sediments. There is no practicable test to detect its presence in waters, or in the flesh of an oyster. 2. In the catchment, for which the Great Lakes Council ("the Council") was responsible and to its knowledge, there were defective septic tanks and other sources of faecal contamination. Before May 1996 the Council's policy was merely to respond to complaints about inadequate treatment of waste. After that month, the Council discontinued even that policy. This discontinuation was not motivated by an insufficiency of resources. 3. In November 1996, heavy rain fell on the catchment area of the Wallis Lake. Oysters were thereafter harvested from it. In the first three months of 1997 there was a surge in the number of reported Hepatitis A cases in New South Wales. The source of this infection was fairly clearly shown to be oysters taken from Wallis Lake after November 1996. This was the first recorded event of the high incidence of an infection originating in the lake. There had however been a similar occurrence in the Tweed River in New South Wales in 1989 to 1990. 4. A class action was brought in the Federal Court on behalf of Mr Ryan and 184 other people who became ill from Hepatitis A as a result of the consumption of contaminated oysters. They claimed in negligence and for breach of the Trade Practices Act 1974 (Cth) ("the Act"). The action was brought against growers (leaseholders) and suppliers of the oysters, the Council and the State of New South Wales ("the State"). No distinction was drawn in these proceedings between the growing company and the related distributing company so far as negligence is concerned, and it is therefore convenient to treat them as one on that issue. 5. At first instance the Federal Court (Wilcox J) gave judgment in favour of Mr Ryan, apportioned liability equally among the defendants and made the following orders[238]:

"1. Judgment be entered in favour of the first applicant, Grant Ryan, in respect of his personal claim, in the sum of $30,000 against each of the following respondents:

It be declared that the first applicant is entitled to succeed against each of the said respondents, in respect of so much of his representative claim as alleges negligence, but only on behalf of those group members who prove damage has been suffered by them.

The first applicant's representative claim of breaches by Graham Barclay Oysters Pty Ltd of ss 74B and 74D of the Trade Practices Act 1974 (Cth) be reserved.

Otherwise the first applicant's representative claim of breaches of the Trade Practices Act be dismissed.

The said respondents pay to the first applicant his costs of the action incurred to date, whether in relation to his personal or representative claim.

The burden of orders (1), (2) and (5) be apportioned between the said respondents as follows:

(c) Graham Barclay Oysters Pty Ltd and Graham Barclay Distributors Pty Ltd - together one third;

and judgment be entered on the cross-claims accordingly.

The matter be listed for further directions at 9.30am on Friday 9 April 1997 or such other time as my Associate may notify the parties."

1. Appeals and cross-appeals were heard by the Full Court of the Federal Court constituted by Lee, Lindgren and Kiefel JJ. In the result, the State, as to one half of the damages, the Council as to one quarter, and Barclay, also as to one quarter, were held to be liable for the loss and damage caused to Mr Ryan by the consumption of the contaminated oysters.

1. Wilcox J summarized the case against the State in this way[239]:

"There are four elements to the applicant's case against the State. First, what counsel describe as their client's 'essential case' is that the State failed to prepare or implement any proper oyster management plan for the lake. This has a number of aspects.

Secondly, the applicant claims [the NSW Environment Protection Authority] failed properly:

(a) to carry out its functions in relation to land, buildings thereon and discharge therefrom so as to ensure they were not sources of pollution; or

(b) appropriately to monitor the water quality of the lake.

Thirdly, the applicant says the Health Department failed to properly monitor and regulate the depuration facilities of oyster farmers; 22 out of the 32 facilities being found defective after the HAV outbreak.

Fourthly, it is said the Heath Department failed to ensure that appropriate water was used for depuration. The suggestion is that Barclay Oysters' depuration intake pipe was too close to the lake floor, so the depuration water was likely to contain virus-bearing sediment."

1. It is unnecessary to deal with the third and fourth of the bases because his Honour summarily dismissed them and no complaint is made about that. He dealt in greater detail with the first two elements in this way[240]:

"In developing the first point, counsel for the applicant note that cl 12B of the Fisheries Management (Aquaculture) Regulation 'required' the Minister to 'determine ... a program to assure the quality of shellfish taken from estuarine waters for sale for human consumption'. This was to be the New South Wales shellfish quality assurance program. There was also to be a local program for each estuary. Counsel observe this Regulation took effect on 1 May 1995; but when the Wallis Lake 'rainfall event' occurred 18 months later, there was not yet either a New South Wales program or a Wallis Lake local program; and this notwithstanding the years of work that preceded the making of the Regulation and the development of a Tweed River quality assurance program following the Norwalk virus epidemic in that estuary in September 1996. Counsel point out that State officers had always known depuration was an inadequate protection against viruses. The fact that a Wallis Lake quality assurance program was approved by the Minister on 19 March 1997, only five weeks after the cause of the HAV outbreak was established, demonstrates the delay was not due to policy or budgetary considerations or the need for extensive consultation. Indeed, they say, the relevant policy had been formulated before the Regulation was promulgated: the program had to 'assure' quality. Given the known limitations of depuration, this meant a quality assurance program would need more than depuration; in practical terms, a sanitary survey and water monitoring. As we have seen, the program approved in March 1997 included both these features. Counsel argue this program could, and should, have been approved earlier. Had it been approved and implemented before November 1996, they suggest, the HAV outbreak would not have occurred.

In relation to the EPA, counsel say that authority failed properly to regulate pollution from the caravan parks; if it be accepted that pollution from that source significantly contributed to the contamination of Wallis Lake and the HAV outbreak, the State is responsible for EPA's neglect.

The council, the Barclay companies, Sciacca and Tadeven all support the applicant's claim against the State.

Counsel for the council say this is not a case of a government being involved in an undertaking only to the extent of determining general policy and making legislation; through the Department of Fisheries, the State was actively involved in the day to day management of the fishery. The State leased the oyster leases to the growers, stipulated the terms of the aquaculture permits under which they operated and received and retained the rentals they paid. Through the Department of Fisheries, it was represented on the Wallis Lake oyster quality assurance committee which, on 22 February 1993, laid down what the Committee Chairman, Mr Moran, called 'stringent guidelines ... regarding the harvesting of oysters in Wallis Lake'. Officers of the Department of Health supervised the depuration process and, for that purpose, required growers to maintain oyster purification log books. They approved and inspected growers' depuration facilities. However, importantly in counsel's submission, those officers were aware of the limitations of the depuration process; in particular its limited effectiveness against viruses. In his publication 'Purification Technology for New South Wales Oysters', Mr Bird had pointed out purification 'is not a perfect system and will not guarantee the absolute public health safety of raw oysters'; depuration was justified as the 'only alternative' on 'a cost risk basis'. Mr Bird had referred to the need to warn consumers about the risks associated with the consumption of raw seafood: '[e]ducation of consumers [about those risks] should be on-going and effective'. Yet there is no evidence of any warning to oyster consumers, whether generally or in relation to Wallis Lake oysters, still less on-going 'education'; and this despite the fact that the Department knew there was no oyster management plan or water testing program for Wallis Lake."

1. His Honour stated his reasons for holding the State liable as follows[241]:

"The substance of the only case against the State that seems open to the applicant is not unlike that which I have upheld against the council: that the State failed to exercise its management powers in such a way as to minimise the risk of HAV infection of oyster consumers. I accept the submission that neither the Fisheries Management Act [1994 (NSW)] nor the Fisheries Management (Aquaculture) Regulation imposed an obligation on the Minister to approve a quality assurance program within any particular period of time. In any event, I would not be prepared to say a delay of about 18 months, between the making of the Regulation and the Wallis Lake 'rainfall event', was so excessive as to constitute a breach of the Minister's obligation, under cl 12B of the Regulation, to approve a quality assurance program. Section 143 of the Act requires consultation with the industry and the public prior to the making of a 'development plan' - a term that seems to include a local quality assurance program. While the evidence does not suggest frenetic activity in relation to the preparation of the New South Wales program or any local program, I cannot say the pace was unreasonably slow."

"This is not a case where the alleged negligence of a government lies in failing to enact appropriate legislation. It is not a case, like McMullin v ICI Australia Operations Pty Ltd[243], where the claim made against government depended on policy, rather than operational, factors[244]. What ought to be the content of a New South Wales shellfish quality assurance program was, no doubt, a matter of policy; to be determined at a political level by the responsible Minister. The same comment may be made about any decision by the Minister to approve or not approve a local quality assurance program. Decisions of that nature fall within Gummow J's description 'quasi‑legislative activity of public authorities'[245]. They are not cognisable by the law of negligence. Consequently, it would have been immaterial, if it were the fact, that a New South Wales or local program had been made that did not include a requirement of a sanitary survey.

However, it does not follow that the absence of a sanitary survey is irrelevant to the case against the State. Although the State cannot be made liable for failing to make a general prescription for sanitary surveys, it may be made liable for ignoring the necessity of a sanitary survey in relation to its management of a particular oyster growing area. In the present case, the State did more than lay down rules and leave the industry to manage itself. Through various agencies, the State actively involved itself in the management of the Wallis Lake oyster industry. This is understandable. The State had a direct financial interest in the industry, as a lessor of oyster leases, as well as indirect financial interests and (presumably) social and political concerns. The determination by the Fisheries Department of the areas to be leased to oyster growers, and the supervision of their use, were activities within the operational area; as were the depuration activities of the Health Department and any decisions by the Minister as to the closure or non-closure of the fishery. The EPA was involved in inspections and directions in relation to premises in the Wallis Lake catchment area. Decisions by EPA regarding the necessity to inspect premises for the purpose of determining whether they were sources of water pollution were decisions in the operational area. In sum total, through various agencies, the New South Wales government exercised substantial managerial control over the Wallis Lake oyster industry. It exercised that control by day-to-day operational decisions.

It is interesting to note that State functionaries themselves recognised the State's managerial role in relation to oyster fisheries. The advisory committee that prepared the 1992 New South Wales oyster quality assurance program included Mr Bird and an officer of the Department of Fisheries. In discussing the concept of quality assurance, the Committee referred to the Health Department's 'powers of enforcement, investigation and if necessary, prosecution' …. In his Second Reading Speech [for the Fisheries Management Act], the Minister for Fisheries spoke about aquaculture permits becoming 'the tool by which the industry is managed' …. Aquaculture permits were to be issued by his Department, managing on behalf of the State.

It seems to me the State's involvement in the management of the Wallis Lake oyster fishery was so extensive and significant as to warrant the conclusion that it gave rise to a duty of care to oyster consumers. As with the council, the State was not obliged to undertake a quality assurance role or guarantee the safety of the oysters harvested in the lake. But it was under a duty to take those steps that were reasonably open to it to minimise the risk of consumers contracting a viral infection from the oysters.

If the State was under a duty of care, that duty was clearly breached. In the extract from their submission … counsel for the State describe 'the requirements for sanitary surveys' as being 'notorious in the industry'. This description accords with the evidence in this case. There is overwhelming evidence as to the desirability of investigation of possible sources of pollution of a shellfish growing area. Although the Americans and Europeans adopt different methods of monitoring water quality, they agree on the need for regular sanitary surveys. As the witnesses made clear, there ought to be a sanitary survey before an area is used for commercial shellfish production. The stated reason is compelling. Depuration cannot be relied on to remove viruses from shellfish. The only way of safeguarding consumers is to prevent the shellfish becoming contaminated in the first place; that means preventing human faecal contamination of growing area waters. Although it may rarely be possible to eliminate the possibility of water contamination, a thorough initial shoreline survey will go a long way towards this, provided it is supplemented by regular subsequent surveys."

1. In the Full Court of the Federal Court, Lee J, after summarizing the relevant legislation, expressed his conclusion in the following paragraphs[246]:

"The State was aware that oyster growers may harvest oysters during or after heavy rain and that no controls had been implemented by the State to prevent such action. In 1981 the State had imposed the depuration system on growers after oysters contaminated by the Norwalk virus had harmed the health of approximately 2,000 people in 1978. The State was aware that depuration alone was not a sufficient safeguard against harm resulting from oysters taken from polluted waters. In 1989/1990 1,200 people suffered harm to health after consuming oysters contaminated by Norwalk or Parvo viruses taken from the waters of the Tweed River. The State understood that pollution of the waters of the Tweed River from which the oysters were taken was caused by human sewage originating either from sewerage systems and septic tanks adjacent to the waters or from vessels navigating the waters. The State closed the Tweed River for a period of not less than two months after the outbreak.

The foregoing amply supports conclusions that the risk of harm being caused to consumers of oysters taken from the Lake was foreseeable; that the State had knowledge of or ought to have known facts that defined the magnitude of that risk; and that in the absence of action by the State to reduce that risk of harm by steps available to it and reasonable in the circumstances, consumers would be exposed to a greater risk of harm than they would either expect or be able to ascertain. No question of 'core policy' was involved in the foregoing nor any decision by the State not to legislate in respect of the matter.

Accordingly, it was open to his Honour to conclude, as he did, that the State was under a duty of care to ensure that powers it had created were exercised to reduce the risk of harm being caused to consumers of oysters and further, to find that the State had breached that duty of care by reason of its failure to manage the waters of the Lake by taking steps to have sanitary surveys of oyster-growing waters undertaken and sources of pollution, or potential pollution, identified and rectified and to implement controls on the harvesting of oysters in conditions known to increase the risk of oyster contamination and, in particular, in failing to close the Lake fishery when those conditions occurred in 1996 and keep the fishery closed until circumstances existed that made it safe for the harvesting of oysters for sale to the public to resume.

Further, it was open to his Honour to conclude that on the balance of probabilities it was the failure of the State to act as described and meet the duty of care imposed upon it, that caused Mr Ryan to suffer injury."

1. Kiefel J, who was of the same opinion as Lee J, in affirming the finding of negligence by the primary judge, summarized her opinion in this way[247]:

"The rainfall in the catchment in November 1996 created a known and significant risk of faecal contamination of oysters, carrying with it a risk of viral infection including HAV. The purpose of the powers given to the Minister to prohibit the harvesting of oysters from an area for a specified period clearly had, as its purpose, the protection of members of the public who might be consumers of oysters, where the Minister had reason to be concerned about the fitness of the oysters for human consumption, as he must have had here if properly informed. In my view, the State thereby came under a duty to exercise its powers and prohibit harvesting until the Minister could be assured of the likelihood of the oysters' fitness for consumption. It was reasonably able to do so, as the letter from the NSW Shellfish Quality Assurance Programme affecting a ban, after reports of the diagnosis of HAV in persons, shows.

In submissions the State complained that, in some respects, his Honour's findings towards a conclusion of negligence went beyond the case as pleaded by its opponents. The power of the State to effect a closure was, however, squarely raised. There was, in any event, little by way of evidence which could have been addressed to it."

"My conclusion that the State was not shown to be liable is, I think, supported by various approaches to the issue. First, I do not think that the array of statutory powers referred to, including the power given by s 189(1) of the Fisheries Management Act to close an oyster fishery where the Minister was satisfied that, relevantly, oysters were, or were likely to be, unfit for human consumption, gave rise to the duty. A duty to exercise that power would, in my view, in accordance with Pyrenees[249] and Lutz[250], not arise unless, at least, the State knew that the oysters to be harvested would be, or would be likely to be, unfit for human consumption. But there had not previously been an outbreak of hepatitis A arising from the consumption of oysters harvested from the Lake. The Lake's growers' practices of depuration and suspension of harvesting for a sufficient period following a 'fresh' had apparently worked in the past. Of course, the possibility of the irresponsible grower was always of general concern, but this did not rise to the required level to impose a duty to exercise statutory powers. Similarly, although, no doubt, instances of faecal contamination over time can be pointed to, the evidence did not establish that the standard of purity of the Lake's water was known to the State to be dangerous by being, for example, significantly lower than that of the water in which oysters were satisfactorily grown and harvested elsewhere in the State or overseas.

But let it be assumed that the standard throughout the State was lower than the standard insisted upon in Europe and the United States of America. It may be said that the State government failed in its duty to the public in this respect. That is, it may be said that in the interests of public health the State should have adopted a different régime from that which it did adopt. In particular, it may be said that the State should have adopted a system involving sanitary surveys of the estuaries or flesh testing or both. I do not think, however, that a failure of that kind, which I would characterise as a failure of policy, necessarily indicates breach of an actionable duty of care to those members of the public who consume oysters.

A further point in relation to 'fishing closures' under s 189 of the Fisheries Management Act is that the duty proposed would have to be understood as one requiring the Minister to consider the question whether he should be satisfied that the Lake's oysters were or were to be likely to be unfit for human consumption. To my mind this highlights, at least in relation to that particular power, the fact that what is involved is a question of priorities and allocation of resources.

I accept the State's submission that, rightly or wrongly, the government of the day took a policy decision in 1994-1995 to the effect that the State would distance itself from the day to day management of the oyster industry in favour of a system of industry-based control to be implemented through two bodies representative of the industry: a State QAP Committee and local estuary-based QAP committees. I do not mean to suggest that by merely recording a policy of 'non‑involvement', a public authority can necessarily avoid incurring legal liability. It is hard to accept that the formal adoption of a policy of non‑intervention would have saved the Shire in Pyrenees or the Council in Lutz. The nature of their legislative powers and the facts and circumstances of their knowledge of the particular danger and the steps taken in relation to it would have prevailed to render them liable nonetheless. But in the present case the State did act consistently with its policy. It did not, for example, embark upon testing the growing waters of the Lake's oyster fishery or the flesh of oysters taken from it. There is no scope for saying that partial action gave rise to 'a common law duty to take care which is to be discharged by the continuation or additional exercise of [partially exercised] powers'[251].

The State's policy is to be contrasted with the learned primary judge's finding that the State 'managed' the oyster fishery in the Lake. A question arises as to the meaning of the notion of 'management' in the present context. The State had ultimate control but this is not management of a kind that would generate a duty of care. Moreover, I do not think the State's roles of licensing and inspecting depuration facilities, inspecting premises from an environmental viewpoint through the EPA, granting oyster leases, issuing aquaculture permits, participating in the Lake's Oyster Quality Assurance Committee as from 14 December 1992, or providing the State's employee, Dr Kerry Jackson, to coordinate the State QAP as from 2 September 1996, constituted 'management' of the day to day oyster and harvesting activity of a kind that would give rise to a duty of care.

I do not accept Mr Ryan's submission that his Honour should have found that the State owed him a duty to ensure that the local QAP was in place by November 1996. His Honour felt unable to reach that conclusion on the evidence and I do not think it is shown that this was a finding of fact at which he was not entitled to arrive.

Mr Ryan submits that control of the fishery was 'ceded' to the State. But in one sense, so is virtually every aspect of the control of the production of food. The individual consumer cannot protect himself or herself and so is 'vulnerable' and hopes that someone will have taken steps to minimise the risk to his or her health. But is it to be said that in every case of 'food poisoning', the State must be liable for having failed to exercise its statutory powers? It seems to me that as a matter of policy the law refrains from imposing the kind of duty on which Mr Ryan is obliged to rely.

I would not conclude, so far as it may remain relevant, that Mr Ryan 'specifically relied on' the State to protect him. There was no dealing between the State and Mr Ryan before he consumed the oysters. As noted earlier, the doctrine of 'general reliance' no longer enjoys support in the High Court as a touchstone of the existence of a duty of care of a public authority to exercise statutory powers.

In my view, on the evidence the State did not 'manage' the shellfish industry in the Lake in any way that might have given rise to a duty of care in favour of Mr Ryan.

If I had thought that the State owed a duty of care to Mr Ryan, I would have held that the State was not shown to have breached it. The case would have called for consideration of what steps the State, acting reasonably, would have taken. This would have immediately raised considerations of the kind referred to by Mason J in Wyong Shire Council v Shirt[252] … as discussed in the context of breach in relation to the Council's appeal. I have referred to some of these considerations as relevant to the State in the context of my treatment of the duty issue above. In the case of the State, questions of the magnitude of the risk, the fact that the Lake's oysters had not previously caused a problem and the cost to the State of taking (and maintaining) the course of action described by his Honour in all of the State's oyster-growing estuaries would have arisen.

For the reasons I gave for allowing the Council's appeal, it is not shown that the course of action that his Honour decided was required (the taking of the steps that were reasonably open to minimise faecal contamination of the Lake) would have prevented Mr Ryan from contracting hepatitis A.

A suggested alternative ground of the State's liability

Because I have held that the State did not owe Mr Ryan a duty of care at all, I need not consider whether it was required to exercise its power to close the fishery (exercise of that power would have prevented Mr Ryan from contracting hepatitis A). But I would not have been prepared to find on the hearing of this appeal that it was required to do so. The issue is one that would call for the making of findings by the primary judge, particularly as to the reasonableness of the State's being required to monitor pollution at the shoreline of all its oyster-growing estuaries and closing oyster-growing businesses from time to time, in the light of the magnitude of the risk in question.

This leaves to be dealt with Mr Ryan's notice of contention insofar as it relates to the State's appeal.

I gave reasons for not accepting Mr Ryan's contention relating to causation based upon a duty to minimise faecal contamination of the Lake when dealing with the Council's appeal.

Another contention relating to the State is that his Honour should have found the State owed to Mr Ryan a duty of care to implement a specific local QAP which required:

(i) a comprehensive and competent sanitary survey of the Lake's oyster fishery 'and surrounding area'; and

(ii) in the absence of such a survey, a closure of the fishery, particularly after a heavy rainfall episode, until such a survey was carried out and it was then safe to re‑open the fishery.

I would not accept the contention. For the reasons given above, it was not incumbent upon the State to exercise its powers at all, in my view.

The remaining contention relating to the State is that his Honour should have found that the State, through the EPA, breached a pleaded duty to ensure that, relevantly, 'the relevant caravan parks' did not pollute the Lake. His Honour rejected the submission by reference to Bendix[253], that is, because although the escape of sewage effluent from caravan parks increased the risk, this was not enough: it would have to be shown that it materially contributed to the actual suffering of the illness by Mr Ryan. With respect, I agree with his Honour."

1. Wilcox J held the associated Barclay companies as grower and supplier to be liable. He said[254]:

"Notwithstanding the attention given to the matter at the hearing, I am not persuaded there was a causal connection between the HAV epidemic and the harvesting undertaken by Barclay Oysters on 23 November 1996 or on 27 November and the immediately succeeding days. The cause of the epidemic was the widespread HAV contamination of the lake. I see no reason to believe the date of harvesting was a critical factor in relation to any particular consumer contracting the disease.

I accept Mr Barclay's evidence that, at all times, he endeavoured to implement the requirements set out in Mr Bird's publication. There is no evidence of any deficiency in Barclay Oysters' depuration plant, in design, construction or maintenance, or in relation to its manner of operation. However, this does not mean the Barclay companies must be exonerated of negligence.

The existence of a duty of care is conceded; the only issues relate to breach of duty and damage. As to breach, it seems to me the applicant is able to establish his case out of matters conceded by Mr Barclay himself. Mr Barclay agreed he was at all times aware:

(a) of the existence of potential sources of viral pollution of the lake;

(b) that depuration was not adequate to remove viruses; and

(c) that E-coli oyster meat testing would not necessarily show viruses.

In this situation, it seems to me apparent that a prudent oyster grower needed to do more than depurate and rely on E-coli flesh tests; ex hypothesi those steps would be an insufficient protection against the known danger. I do not agree with the State's submission that Barclay Oysters' omission lay in its failures further to defer harvesting after the November rain and to carry out PCR flesh testing and faecal coliform water testing. Useful though these measures might have been, they would not necessarily have protected consumers of the oysters. As already explained, viruses could have remained in the water, or in unharvested oysters, for many weeks after cessation of the rain, and after faecal coliform levels had dropped back to normal limits; and their existence would not necessarily have been revealed by PCR testing. The only real protection to consumers was to prevent viral contamination in the first place. As is the case with the council and the State, Barclay Oysters was not obliged to ensure the absence of viruses, but it was obliged to take the steps reasonably open to it to obtain a virus-free growing environment and, if this was impossible, to refrain from selling oysters for human consumption, except perhaps with a warning about the risk in eating them.

Counsel for the Barclay companies cross-examined the witnesses who urged the need for a sanitary survey by obtaining their agreement that they would not ordinarily expect this to be undertaken by a single producer. Counsel seemed to assume that this agreement absolved their clients from any responsibility for the absence of a sanitary survey. I do not see the matter that way. The Barclay companies could have made a significant contribution to risk reduction by having a few men walk that part of the foreshores of the lake, rivers and islands that is publicly accessible - and that is most of it - and list all items of apparent concern. However, a satisfactory sanitary survey required access to all premises and possession of enforcement powers. Governmental or local governmental involvement was essential. This does not let the Barclay companies off the hook; neither they nor any of the committees with which they were associated attempted to procure governmental or local governmental involvement. The evidence does not reveal any approach to the council or a State agency for the making of a sanitary survey, with or without support (manpower or financial) from the local industry. The Barclay companies (and, apparently, the other local oyster producers) were as oblivious to the need for a sanitary survey as was the State. Given that they actually produced the product that put consumers at risk, they cannot escape some responsibility for the lack of a sanitary survey.

If the oyster producers had endeavoured, and failed, to persuade the council or the State to undertake a proper sanitary survey, they would have needed to consider other options. One option - presumably expensive - might have been to relay the oysters in other waters for a period before sale. There may have been other possibilities. It is not necessary to go into them. It is enough to say it was not sufficient for the Barclay companies (or any other producer) to shrug off their knowledge of the possible pollution of the lake by saying this was someone else's responsibility.

In my opinion, in selling without warning oysters grown in waters known to be subject to possible undetectable viral contamination, both Barclay companies breached their duty of care to ultimate consumers of the oysters. Because it is apparent that the viral infection sustained by Mr Ryan, and the group members who became ill after consuming Barclay oysters, stemmed from the contamination of the lake, there is a clear causal connection between the breach and the damage.

It does not follow that all distributors of Wallis Lake oysters are liable in negligence to HAV infected consumers of their oysters. Barclay Distributors is in the unusual position of being controlled by a person (Mr Graham Barclay) who is also the controller of a grower company. Barclay Distributors is therefore fixed with an unusual degree of knowledge about the circumstances of production of the oysters it distributes. Its knowledge may exceed that of distributors based elsewhere; and, even more so, people (perhaps including restaurateurs) who purchase oysters for commercial purposes without knowledge of the circumstances, even location, of their production."

1. Lee J and Kiefel J in the Full Court agreed with the conclusion of the primary judge that the Barclay companies were negligent. Lindgren J was of a different opinion.
2. Kiefel J, with whom Lee J generally agreed on the issue of Barclay's negligence said this[255]:

"His Honour the primary judge referred to the evidence of Mr Barclay, that he was aware of the existence of potential sources of viral pollution of the lake; that depuration was not adequate to remove viruses; and that flesh testing would not necessarily detect viruses. His Honour referred to what the Barclays companies should have done and focussed, principally, upon the 'significant contribution to risk reduction' it could have made. For the reasons I have given with respect to steps which his Honour found might have been undertaken by others, but which were not likely to amount to prevention or detection, I am respectfully unable to agree that this was the proper measure of the duty owed by the Barclays companies. His Honour however also identified, as an alternative to attempts to prevent contamination, and in the event that it proved impossible to obtain a virus-free growing environment, the requirement that the Barclays companies refrain from selling oysters for human consumption, except perhaps with a warning about the risk in eating them. Ultimately, it was the absence of warning when selling which his Honour held to constitute negligence.

It follows from the view I have expressed above concerning the State's duty, and the basis for it, that even if the harvesting of oysters had not been prohibited in the circumstances prevailing, as it should have been, the Barclays companies should not have supplied oysters for sale until a sufficient period had elapsed by which the risk of contamination could be regarded as acceptable or tests sufficiently indicated that to be the case. That was the effect of the expert evidence. A cessation of harvesting and supply during and up to a few days after the rainfall could never suffice; nor could 36 hours of depuration thereafter. His Honour determined liability, ultimately, on the basis that a warning was not given of the danger which remained in consuming oysters from the area. The requirement of a warning would of course render nugatory the supply of oysters for sale."

1. Lindgren J summarized his dissenting opinion in this way[256]:

"It seems to me that on the evidence of the lack of any previous outbreak of health problems arising from the consumption of oysters grown in the Lake and the lack of knowledge otherwise of Mr Barclay of the existence of an actual problem as distinct from potential sources of faecal contamination of the Lake, the Barclay companies' duty of care did not reasonably require them either to take the course that his Honour outlined or to suffer a closure of their business until somehow they could be completely assured that they were putting into the market a product that was free of defects."

1. In dealing with the position of the Council, the local authority in whose jurisdiction the Lake lay, Wilcox J first summarized its powers and duties. Not surprisingly, these included extensive powers to supervise and manage the treatment of effluent, and to insist upon the abatement of sources of it. Next, his Honour referred to the Council's awareness of problems of seepage from septic tanks and the need to take steps to deal with them. His Honour's reasons for holding the Council liable in negligence are to be found in the following passage[257]:

"The applicant need not prove the particular source or sources of the HAV contamination. The HAV oyster contamination came from human faecal pollution of the lake. The expert evidence establishes the probability that this pollution came from multiple points, predominantly land-based. All of those points were subject to council control. The pollution occurred because the council did not exercise its powers in a responsible manner; although it knew there was a problem, the council allowed the continuation of pollution from those points. It does not matter that it is impossible to say which of those pollution points introduced the HAV contaminated faeces into the lake.

It is not necessary to determine whether the council owed a duty of care to the oyster growers. It was certainly not obliged to undertake general quality control of the oysters harvested from the lake. However, if the content of the supposed duty of care is defined merely as being an obligation to exercise the Council's statutory powers in such a manner as to minimise pollution of the lake, I see no reason for rejecting such a duty; like Mr and Mrs Day in Pyrenees[258], the growers were entitled to expect the council to exercise its powers in such a manner as to avoid a nuisance that would damage their property (the oysters) and cause them consequential loss.

If there was a duty of care to oyster consumers, as I hold, there can be little doubt it was breached. Prior to the HAV epidemic, the council took no steps to identify point pollution sources. Although the 1989-1993 water tests showed high faecal coliform levels after rain, including in stormwater drains, council took no steps to ascertain - for example by E‑coli tests of that water - whether human sewage effluent contributed to those high levels. Given that the drains served the towns of Forster and Tuncurry, this was at least a distinct possibility. If tests had revealed significant E-coli levels, this would have indicated a problem of discharge from sewerage pumping stations or septic tanks. Armed with that information, the council could have taken samples from various locations along the stormwater drains to trace the source of the pollution and then taken whatever steps were necessary to ensure the problem was fixed. All this would have been no more than good housekeeping for a local government authority that took its responsibilities seriously. It is the Shoalhaven Council approach, according to Mr Papworth.

However, it is not necessary for the applicant to depend upon council's failure to trace effluent emissions. The evidence establishes council was aware of serious sewage effluent problems in the villages (Nabiac and Cooloongolook) draining to the lake's tributaries. Anybody who gave the matter thought would have realised there was a possibility that viruses in that effluent might reach the lake and contaminate the oysters. That suspicion would have been heightened (at least in relation to Nabiac) if the person read the Laxton report, a copy of which was in council's possession.

Closer to home, numerous sites were contributors, or potential contributors, to estuarine pollution; for example, the two caravan parks, the Little Street public toilet, the toilet pits on the islands and the houseboats on the lake. If council did not know about these problems, that was because it chose not to look. Until May 1996, council's policy was merely to respond to complaints; and this despite the fact that council's officers knew the complaints they received represented only the tip of the iceberg, that pollution from septic tanks was a widespread problem. The responsible reaction to such knowledge would have been to institute a sanitary survey, especially of premises that drained to estuarine waters. Astonishingly, in May 1996 council's officers took the opposite course, determining not even to respond to complaints. It may not be coincidence that the HAV outbreak occurred shortly after the first heavy rain of the next oyster season."

"Counsel for the Council submit the establishment in 1993 of the Wallis Lake oyster farmers quality assurance committee brought to an end any responsibility council might have had for ensuring the estuarine water quality was satisfactory for the growing of oysters; the oyster farmers took over responsibility for water quality, in conjunction with relevant State officers.

One difficulty about this submission is that council was a major participant in the committee; Mr Chadban and Mr Powell were members and Mr Chadban acted as Secretary. The membership of the committee reflected the fact that the oyster growers, the council and various State agencies all saw themselves as having an interest in the safety of Wallis Lake oysters. The committee's deliberations show its members recognised this involved attention to water quality."

"I find the council breached its duty of care to the applicant and group members. As it is clear the breach occasioned damage to the applicant, he is entitled to recover against the council in respect of his personal claim. He is also entitled to recover against the council in relation to his representative claim, subject to proof of the damage suffered by group members."

1. The Full Court upheld the Council's appeal. Kiefel J said this[261]:

"It is clear from his Honour's reasons that it was considered that there was much that the Council could have done. So much can, I think be accepted. That does not however, in my respectful view, answer the question whether it came under a duty to take action."

"A conclusion that the Council was under an obligation to use the powers it had to protect oyster consumers from injury cannot, in my view, be reached without ascertaining the nature of those statutory powers and what they were directed to. It will be recalled that in Pyrenees[263] there was coincidence between the action which was necessary to prevent the fire, the powers given to the Council and the purpose for which they were given. In my view the provisions here referable to water pollution and public health, whilst no doubt sufficient to authorise the undertaking of surveys or water testing, were not such as to place the Council in a position where it was obliged to prevent the risk of injury, assuming for present purposes that it could have done so effectively. His Honour set out the relevant statutory provisions. The Local Government Act 1993 (NSW), pursuant to which the Council obtained its wider powers, had amongst its stated purposes the provision of the legal framework for an effective and environmentally responsible local government. More specifically, the Council had the power to approve the carrying out of 'sewerage work', which was defined to include works relating to septic tanks or effluent systems and Council sewers. In that connexion, it was to have regard to 'the protection and promotion of public health'. It had power to require compliance to 'relevant standards' relating to sewerage systems and to require that owners or occupiers of premises (a term widely defined) do or refrain from doing, specified things 'to prevent environmental damage' or to cease an activity which was a threat to public health. It had the power to abate a nuisance, or to require that it be abated. It had powers of entry into premises in aid of its other powers. It had a general power to remove, disperse, destroy or mitigate the pollution of water, at the direction of the Environmental Protection Authority. There was, however, no statutory provision which had as its apparent purpose the prevention of contamination of oysters, the water in which they were grown, or the protection of consumers, and which required the Council to use one or more of its powers in a given circumstance to achieve those ends. The powers given to the Council, referred to above, which allowed it to undertake some action and which might have had some effect upon the risk in question may be contrasted with those in Pyrenees, by which the Council could be said to have been obliged to act so as to ensure the defective fireplace was remedied or not used. It may also be observed that the Council's argument, concerning the lack of definition of the content of any alleged duty, reflects the lack of an obligation directed to a specific end."

"Had the Council undertaken the management strategies referred to by his Honour it would follow from the evidence that the best outcome would have been a reduction of the risk. A finding that it would actually 'minimise' is not, with respect, apparent and in any event the Council could not have acted such as to prevent the viral contamination and the injury in question.

In order to involve liability, action or inaction must be sufficiently important and closely connected with the incident in question so as to make it reasonable, on a broad commonsense view, to regard its author as responsible for it in law: Fitzgerald v Penn[265]. As to the possibility that any inaction on the Council's part could be said to have materially increased the risk of injury, the Council referred to the decision of Mason P in Bendix[266], where his Honour held that the law did not equate that situation with one where it could be said the defendant materially contributed to it (as to which see March v E & MH Stramare Pty Ltd[267]). It does not seem to me that the Council's position is to be determined by such considerations, for in my view any general omission on its part could only be said to have left oyster consumers exposed to the same risk. The only relevant increase in risk arose not from its conduct, but from the effect of heavy rainfall. Tested another way, one could not say, on balance, that the performance of the duty identified would have averted the harm"[268].

1. After discussing the cases, Lindgren J stated his conclusion in this way[269]:

"In my respectful opinion, it would be not an incremental development but a major change of direction in the law if we were to hold that the Council owed an actionable duty of care to the oyster consuming public in the circumstances of this case.

The Council would be under a duty to exercise each of its powers where injury to members of the public was foreseeable if it did not do so, even if, as here, the exercise of the power could do no more than reduce the risk of the injury. The Council would have to take all steps reasonably available to it in respect of all of the powers or be subject to the risk of indeterminate and potentially huge liabilities, the extent of which was beyond its control."

1. Lee J agreed with the primary judge. His Honour was of the opinion that the proper application of the reasoning of this Court in Crimmins v Stevedoring Industry Finance Committee[270] dictated that result.

1. Because the primary judge's finding of negligence against the State was made on the basis that the State was "the ultimate manager of the fishery"[271], it is necessary to consider the statutory powers and functions of the agencies of the State to which the parties referred.
2. In the Fisheries Management Act the statutory definition of "fish" includes "oysters" (s 5). Commercial oyster growers were required to hold an aquaculture permit (s 144).
3. The responsibility for the grant of oyster leases and the issue of aquaculture permits was the Minister's (s 146). He or she had power to determine commercial aquaculture industry development plans (ss 58 and 143) as well as a general power to close any fishery, and a specific power to prohibit harvesting if satisfied that fish (including oysters) were, or were likely to be, unfit for human consumption (s 189).
4. On 1 May 1995 the Fisheries Management (Aquaculture) Regulation (NSW) came into force. It required the Minister to determine a commercial aquaculture industry development plan to assure the quality of shellfish taken for human consumption (reg 12B). It also required the Minister to appoint State and local Shellfish Quality Assurance Committees (reg 12C), the latter having responsibility for the establishment and administration of local shellfish quality assurance programs in designated growing areas (reg 12E).
5. By November 1996, the State Committee had been appointed but the New South Wales Shellfish Quality Assurance program had not been developed. In December 1992 however, local oyster growers established a voluntary local shellfish quality assurance committee.

1. The principal submission of the State was that changes to the legislation and the regulations in 1994 and 1995 indicated considered rejection of any idea that the State would assume responsibility for quality control management in any local oyster growing area: that this was not only a policy decision, it was also a disavowal of any active day-to-day role in any local growing area.
2. The introduction of these regulations, the State submits, brought to fruition a long discussed regime for quality assurance to be funded and administered by the industry itself.
3. It follows, the State submits, that the regulatory changes, because they rejected any requirement for classification of oyster growing areas, and because they did not require mandatory sanitary surveys, must be taken to have recognized the existence of foreseeable risks in every oyster growing area. Moreover, they must be taken to have recognised the likely continuation of those risks, at least until the establishment of a quality assurance program. Those matters, the State contended, are incompatible with the existence of a duty of care to consumers of oysters.
4. The State's regulatory powers were not therefore powers of day-to-day control. They were regulatory powers, the exercise of which depended on the evaluation of competing economic and community interests inconsistent with the existence of a common law duty of care requiring their exercise[272].

1. Mr Ryan drew attention to several of the provisions of the Local Government Act 1993 (NSW) ("the Local Act") as manifesting in sum a statutory obligation on the part of the Council to take steps for the prevention of contamination of the lake in default of which an infected consumer such as he might sue. First, reference was made to stated purposes of the Act: "to provide the legal framework for an effective, efficient, environmentally responsible … system of local government in New South Wales" (s 7(a)); "to give councils … a role in the management … of the resources of their areas" (s 7(d)); and, "to require councils … to have regard to the principles of ecologically sustainable development in carrying out their responsibilities" (s 7(e)). Mr Ryan also pointed out that s 68 of the Local Act provided that certain activities, including the disposal and management of waste within the area of the local authority, could only be undertaken with the prior approval of the Council. Reference was also made to s 125 which empowered the Council to abate a nuisance, and s 191 which authorized the Council, by its employees or others, to enter premises in order to carry out a function, which would include the abatement of an effluent nuisance. Similarly, s 192 made provision for inspections and investigations by the Council and the recovery of the cost thereof pursuant to s 197. Other sections and regulations of the Act, such as s 678 and s 697, and reg 45, were also the subject of submissions because they enlarged the powers of the Council to take steps for the abatement of nuisances, and the protection of public health.
2. Mr Ryan also drew the attention of the Court to the Clean Waters Act 1970 (NSW). Section 27 of that Act conferred upon the Council power to do such things, and to take such action as might be necessary to remove, disperse, destroy, or mitigate pollution, and to enter and inspect places and premises at the expense of a person responsible at that person's expense.

1. Mr Ryan's submission is that there is no doubt that the Council did have statutory power to protect him and other consumers of oysters: the fact that the Council's powers are not expressed to be duties should not be fatal to his claim. As to the nature and purpose of the powers of the Council, he draws attention to s 7 of the Local Act, from which the true legislative purposes may be inferred. These, together with the powers granted by the interconnected provisions of that Act and other legislation, amount not only to a formidable array of power, but also a duty to exercise that power. So to hold would not, it is argued, be to produce an incompatibility with other functions and powers of the Council: nor would recognition of a duty of care in these circumstances distort the law or impinge upon the exercise of other statutory powers. Mr Ryan further argues that the class to which he belongs is not an indeterminate one, that its members can be clearly identified, and that it is a class for whose benefit it should be accepted the Council would, and should exercise its powers. The exercise of the relevant powers would not involve the taking of legislative, or quasi-legislative steps, and would not relate to a "core-policy"[273] function. Mr Ryan made the further point that the injury that he suffered was physical injury, and not pure economic loss, towards the former of which the law has more consistently been tender than the latter. The Council had a large measure of control over the situation, that is to say the state of sanitary containment in the area of the Council. Consumers were particularly vulnerable and had little or no means of self-protection against contaminated oysters.
2. Mr Ryan's submission which I have summarized adopts much of the language and some of the tests which have been formulated by various justices of this Court in other cases.
3. However, as will also appear, the tests have not commanded unanimous support, and the situations in which their application has been considered may all be distinguished from one another.

1. As long ago as 1880 Earl Cairns LC said this:[274]

"[t]here may be something in the nature of the thing empowered to be done, something in the object for which it is to be done, something in the conditions under which it is to be done, something in the title of the person or persons for whose benefit the power is to be exercised, which may couple the power with a duty, and make it the duty of the person in whom the power is reposed, to exercise that power when called upon to do so."

It may, with respect, be doubted whether it is possible to make a more accurate or better statement in relation to the powers and obligations of a statutory authority. Another way of expressing his Lordship's view is to say that there has to be something either unique (as it was in Crimmins[275] case) or special about the role, or involvement of the authority, or the relationship between it and the affected person, or special about the non-exercise of the power such as marked irrationality in abstention from employing it[276], before liability may be sheeted home to the former[277]. It is of course understandable that courts should strive to find and state a principle capable of universal application, but so far such a principle has remained just as elusive as has any alternative formula to "beyond reasonable doubt" in criminal cases, although from time to time various opinions have held sway. The test propounded by Mason J in Sutherland Shire Council v Heyman[278], of general reliance which I would read to be little different from that stated by Deane J in that case, enjoyed a considerable amount of support. It was adopted and applied by McHugh JA in the Court of Appeal in New South Wales in Lutz,[279] and restated by his Honour in the High Court in Pyrenees[280] albeit with some qualifications. But Pyrenees also sounded its demise on its express disapproval by three of the Justices, Brennan CJ[281], Gummow[282] and Kirby JJ[283]. The Chief Justice in that case was influenced by the speech of Lord Hoffmann (with whom Lord Goff of Chieveley and Lord Jauncey of Tullichettle agreed) in Stovin v Wise[284], which had been decided shortly before the Court was called upon to reconsider what had been said by Mason J in Sutherland. Lord Hoffmann said[285]:

"In the case of a mere statutory power, there is the further point that the legislature has chosen to confer a discretion rather than create a duty. Of course there may be cases in which Parliament has chosen to confer a power because the subject matter did not permit a duty to be stated with sufficient precision. It may nevertheless have contemplated that in circumstances in which it would be irrational not to exercise the power, a person who suffered loss because it had not been exercised, or not properly exercised, would be entitled to compensation. I therefore do not say that a statutory 'may' can never give rise to a common law duty of care. I prefer to leave open the question of whether the Anns case[286] was wrong to create any exception to Lord Romer's statement of principle in the East Suffolk case[287] and I shall go on to consider the circumstances (such as 'general reliance') in which it has been suggested that such a duty might arise. But the fact that Parliament has conferred a discretion must be some indication that the policy of the act conferring the power was not to create a right to compensation. The need to have regard to the policy of the statute therefore means that exceptions will be rare.

In summary, therefore, I think that the minimum preconditions for basing a duty of care upon the existence of a statutory power, if it can be done at all, are, first, that it would in the circumstances have been irrational not to have exercised the power, so that there was in effect a public law duty to act, and secondly, that there are exceptional grounds for holding that the policy of the statute requires compensation to be paid to persons who suffer loss because the power was not exercised."

1. Another test altogether, and indeed a potentially far-reaching one, was stated by Gibbs CJ in Sutherland. His Honour said[288]:

"Once it is accepted, as it must be, that the ordinary principles of the law of negligence apply to public authorities, it follows that they are liable for damage caused by a negligent failure to act when they are under a duty to act, or for a negligent failure to consider whether to exercise a power conferred on them with the intention that it should be exercised if and when the public interest requires it."

1. Only Wilson J agreed with the Chief Justice in Sutherland, and the statement that I have just quoted has not been adopted or applied in this Court since Sutherland.
2. In Pyrenees, Kirby J was attracted to a third test which involved three stages and which had been expressed and applied by the House of Lords in Caparo Industries Plc v Dickman[289]. It involves the asking of three questions, as to foreseeability, relationship, and what should be regarded as fair, just and reasonable in the circumstances. His Honour was the only Justice to embrace that test in Pyrenees, and it has been expressly rejected in this country subsequently in Perre v Apand Pty Ltd[290].
3. I will put to one side for the time being the decision of this Court in Crimmins[291] and go to the more recent case of Brodie v Singleton Shire Council[292] in which this Court effectively abolished the distinction between nonfeasance and misfeasance on the part of road authorities upon which the "highway rule" was based. There, Gaudron, McHugh and Gummow JJ in adopting a test of control, said this[293]:

"The decisions of this Court in Sutherland Shire Council v Heyman[294], Pyrenees Shire Council v Day[295], Romeo v Conservation Commission (NT)[296] and Crimmins v Stevedoring Industry Finance Committee[297] are important for this litigation. Whatever may be the general significance today in tort law of the distinction between misfeasance and non-feasance, it has become more clearly understood that, on occasions, the powers vested by statute in a public authority may give it such a significant and special measure of control over the safety of the person or property of citizens as to impose upon the authority a duty of care. This may oblige the particular authority to exercise those powers to avert a danger to safety or to bring the danger to the knowledge of citizens otherwise at hazard from the danger. In this regard, the factor of control is of fundamental importance[298].

It is often the case that statutory bodies which are alleged to have been negligent because they failed to exercise statutory powers have no control over the source of the risk of harm to those who suffer injury. Authorities having the control of highways are in a different position. They have physical control over the object or structure which is the source of the risk of harm. This places highway authorities in a category apart from other recipients of statutory powers."

1. Their Honours did not see the possibility that courts might be called upon to examine the allocation of resources by a highway authority as reason to maintain the highway rule[299]. The formulation which their Honours adopted is set out in the following paragraph[300]:

"The duty which arises under the common law of Australia may now be considered. Authorities having statutory powers of the nature of those conferred by the LG Act upon the present respondents to design or construct roads, or carry out works or repairs upon them, are obliged to take reasonable care that their exercise of or failure to exercise those powers does not create a foreseeable risk of harm to a class of persons (road users) which includes the plaintiff. Where the state of a roadway, whether from design, construction, works or non-repair, poses a risk to that class of persons, then, to discharge its duty of care, an authority with power to remedy the risk is obliged to take reasonable steps by the exercise of its powers within a reasonable time to address the risk. If the risk be unknown to the authority or latent and only discoverable by inspection, then to discharge its duty of care an authority having power to inspect is obliged to take reasonable steps to ascertain the existence of latent dangers which might reasonably be suspected to exist."

1. Although Hayne J was also in favour of the abolition of the highway rule, his Honour's formulation of the duty of care to replace it was somewhat different from the formulation in the joint judgment. In a passage which resonates with the statement of Earl Cairns LC and the speech of Lord Hoffmann that I earlier quoted, his Honour said this[301]:

"Rather, reference must be made[302] to 'the nature, scope and terms of the statute, including the nature of the evil against which it is directed, the nature of the conduct prescribed, the pre-existing state of the law, and, generally, the whole range of circumstances relevant upon a question of statutory interpretation' (emphasis added). Ordinarily, the more general the statutory duty and the wider the class of persons in the community who it may be expected will derive benefit from its performance, the less likely is it that the statute can be construed as conferring an individual right of action for damages for its non-performance. In particular, a statutory provision giving care, control and management of some piece of infrastructure basic to modern society, like roads, is an unpromising start for a contention that, properly understood, the statute is to be construed as providing for a private right of action."

1. Crimmins does, I think, stand apart from the other cases to which I have referred. Whilst it was a case in which the Court effectively treated powers and functions as giving rise to duties of care, the factual and statutory contexts were both very special. What distinguished the powers and functions there was that if they were not in fact exercised, then the industry which was a uniquely organized one, would hardly have been able to function at all, or with any degree of efficiency[303].
2. The most recent case which has some bearing upon this one is Modbury Triangle Shopping Centre Pty Ltd v Anzil[304]. Its relevance lies in the Court's reluctance, and ultimate refusal there, to impose upon an occupier, a duty to take reasonable care to prevent harm inflicted by the criminal behaviour of a third party. It is not without significance in these appeals, that almost certainly those persons within the area of the Council who failed to prevent the run-off of faecal effluent were guilty of offences against regulations or enactments, as indeed may the Council itself have been in respect of areas which it occupied. However, as to these, a caravan park and other public areas it cannot be established that they alone, or at all, were the source of the faecal matter which caused the contamination and illness.
3. In my opinion, the authorities to which I have referred do not stand for one clear test which is applicable to this case. Even though the Council here did have some measure of control of the land, and the management of waste on it in its area, it was not in the same position as a highway authority. The reasoning of the three Justices responsible for the joint judgment in Brodie[305] depends in part at least upon the fact that highway authorities stand in a different position from other authorities in that they have actual physical control and occupation of the dedicated road area the source of the risk of harm. In that sense they are in a similar position to occupiers and in a category apart from other recipients of statutory power.

1. I return to where I started in this section of my reasons, to the statement of Earl Cairns LC which requires that there be something in all of the circumstances, including of course the terms of the conferral of the powers, which requires that the power be coupled with a duty; or, as Hayne J put it in Brodie, "[something in] the whole range of circumstances relevant upon a question of statutory interpretation"[306]; or as Lord Hoffmann put it in Stovin v Wise, irrationality in an abstention from exercising the power[307] or some other exceptional matter, or indicator of an intention to permit a person to sue. Unless these conditions are satisfied, in my opinion no relevant duty of care will arise.
2. True it may be, that vulnerability, power, control, generality or particularity of the class, the resources of, and demands upon the authority, may each be, in a given case, a relevant circumstance, but none should, I think, of itself be decisive. Nor do I think it convenient or satisfactory to pose a test whether a particular function of an authority involves a core, or a non-core function, or relates to a matter of policy or executive action[308]. Not the only problem about such a test is the inevitable difficulty of distinguishing functions, and the need for statutory authorities to make a political assessment of priorities.
3. In my opinion, no better test can be stated than that of Earl Cairns LC modified to take account of Lord Hoffmann's opinion as to irrationality of abstention from exercise, or other exceptional circumstance, and which in form only, but not in substance I would regard as being similar to that of Hayne J in Brodie. It was, it may also be observed, a test which quite clearly appealed to Brennan J in Sutherland as appears from his Honour's citation of it in that case.

1. Applying the test to which I have just referred, I would conclude that the State is not liable. There had been no previous serious outbreak of Hepatitis A as a result of faecal contamination of the waters of the lake. There was a management council in place which had been supported by both the Council and State which, not unreasonably, could be expected to ensure that the industry regulated itself in a way that not only would protect the public as oyster consumers, but also would, in the interests of oyster growers and suppliers themselves, take steps to maintain control of quality and purity. There seems to be no suggestion that the rainfall in November 1996 was unprecedented. What I have just said also bears upon the submission that the State should have exercised its power under s 189 of the Fisheries Management Act to close the oyster fishery in the lake for a longer period than the growers themselves did. The absence of previous outbreaks, and the apparently satisfactory nature of what had been done in the past provides an answer to this. I do not think that in the circumstances, that elsewhere, and on other occasions, for instance the infectious contamination had occurred in the Tweed River in 1989 to 1990, meant that the State should have adopted further measures and caused the fishery to be closed for longer than it was. That might mean that an outbreak in the lake was foreseeable, but foreseeability alone is not enough to establish liability. It is an overstatement in my opinion to say, as the primary judge did, that the involvement of the State in the management of the fishery was so extensive that it gave rise to a duty of care to oyster consumers. His Honour the primary judge dwelt at some length on the need for regular sanitary surveys. No doubt these were highly desirable. But with all due respect, they were not the answer, although they might have been the first step in providing it. Their particular utility would lie only when effect was given to them by the taking of all necessary steps to abate the potential sources of contamination which they revealed. Such a process, however desirable it might be, would require time, money, labour, other resources, and possibly the deferral of other highly desirable measures. The State, furthermore, was not in the position of a highway authority having actual physical control of the land from which the effluent was released.
2. It follows that I do not think that there is any particular circumstance in this case which gives rise to a duty of care, a breach of which by the State would entitle an infected oyster consumer such as Mr Ryan to sue it. I do not overlook such important features as that the State did have and exercised a measure of control over the industry, that a matter of public health was involved, and that an oyster consumer is vulnerable and without any personal means whatsoever of guarding against a contaminated oyster. These are all relevant considerations. But they are not unique ones. Daily, agencies of the State and local authorities are concerned with issues of public health. In practical terms it would be impossible for any authority to police all potential sources of dangerous food just as it would be for such an agency to identify and eradicate all potential sources of danger of any kind. What distinguished the source of danger in Pyrenees is not present here: its precise identification by the Council and inadequate attempts by it to remove it. The massive obligation of the State to which a contrary view would give rise is a relevant and important circumstance to which I should have regard, and which, although not decisive, weighs in the balance. In abstaining from doing more than it did the State was not, in my opinion, acting irrationally.

1. For the purposes of this case I am unable to distinguish in any significant way between the State and the Council. In form only, rather than in substance (with three exceptions only) their powers were much the same. The first two exceptions are that the State could have been a great deal more interventionist in the management of the oyster fishery had it wished, and it did have the power of closure. However, had the Council brought to the attention of both the participants in the industry and the public, facts which it knew as well as the State, as to the sources of potential contamination, and the risks to which they gave rise, the practical consequence would probably have been the same, that oysters from the lake would not have been consumed by members of the public until their quality could be reasonably assured. It is correct, as Kiefel J put it in the Full Court there was no doubt much that the Council could have done. The third exception is that unlike however in the case of the State, there was no statutory provision which had as its particular purpose the possible management of the industry or the prevention of contamination of oysters. There was no direct and active involvement by the Council in the control of the industry in anything like the same way as the Council involved itself in the attempt to eradicate the potential source of a fire in Pyrenees. Asking the same questions and applying the same test as I have in relation to the State, I conclude that the Council is not liable. The disposition of the appeals involving the Council should result in its not being held liable to Mr Ryan.

1. The law so far as the liability of Barclay is concerned is well settled. It was obliged to take reasonable care for the safety of persons who consumed its oysters. So much was conceded by Barclay. Bearing upon that matter are these facts: of most importance that Barclay was carrying on a commercial activity in the cultivation and sale of oysters, that Barclay was not only obliged to have, but also had a great deal of knowledge about the cultivation and harvesting of oysters, and in particular of the potential for infection after heavy rain; that oysters were susceptible to faecal contamination; and that there were numerous potential sources of such contamination in the catchment of the lake. Useful measures were available and had been adopted by Barclay but they could provide no complete defence against Hepatitis A infection.
2. The trial judge made a finding that Barclay could have made a significant contribution to the reduction of risk by causing an inspection to be made of the foreshores of the lake. Barclay was armed with the knowledge of outbreaks of Hepatitis A on other occasions in other places. Hepatitis A is a particularly unpleasant and dangerous illness. By a combination of inspections (as held by the primary judge) and a suspension of harvesting for longer than a few days, the risk might have significantly been reduced. As grower and supplier for profit, Barclay could and should be expected to provide safe oysters. These matters led the trial judge to make what was essentially a finding of fact, that in failing to adopt those measures Barclay was in breach of its duty of care to Mr Ryan.
3. I might not perhaps have reached the same conclusion myself. As Starke J pointed out in Australian Knitting Mills v Grant[309] untoward results or accidents cannot with the greatest of care be wholly eliminated in any industrial process, an observation which could be made with at least equal force to a process of production of natural products. There were however facts upon which his Honour was entitled to reach the conclusion as to the liability of Barclay that he did. There are now concurrent findings of fact to a similar effect by two judges of the Full Court. Notwithstanding therefore the evidence of an absence of any previous outbreak by reason of contaminated oysters from Wallis Lake, and Barclay's incapacity itself to remove the sources of contamination, relevant factors which Lindgren J in dissent thought decisive, I am not prepared to depart from the holding of negligence against Barclay by the primary judge and the majority in the Full Court.

1. The judgment and orders of the Full Court of the Federal Court should be quashed and judgment and orders as follows substituted:
2. Judgment be entered in favour of Mr Ryan in the sum of $25,000 with interest of $2,000 against Graham Barclay Oysters Pty Ltd and Graham Barclay Distributors Pty Ltd ("Barclays");
3. Order that Barclays pay Mr Ryan's costs of the trial, and the appeals to the Full Court of the Federal Court and this Court confined to the litigation of the issues between them;
4. Order that Mr Ryan pay the costs of the State of New South Wales and the Great Lakes Council, of the trial, the appeals to the Full Court of the Federal Court and this Court;
5. Order that Barclays pay to Mr Ryan a sum equal to the additional costs incurred by him by reason of the litigation of issues arising solely between Barclays and the State and the Council or any of them inter se, at and of the trial, the appeal to the Full Court of the Federal Court and this Court; and
6. Order that the matter be remitted to the primary judge for the trial of any outstanding issues and disposition of the action.
