The Negligence Claim
53 Both parties referred us to Gould v Vaggelas (1985) 157 CLR 215 at 236 where Wilson J set out the principles to be applied when considering whether a misrepresentation has induced the representee to enter into a contract.
"1. Notwithstanding that a representation is both false and fraudulent, if the representee does not rely upon it he has no case.
2. If a material representation is made which is calculated to induce the representee to enter into a contract and that person in fact enters into the contract there arises a fair inference of fact that he was induced to do so by the representation.
3. The inference may be rebutted, for example, by showing that the representee, before he entered into the contract, either was possessed of actual knowledge of the true facts and knew them to be true or alternatively made it plain that whether he knew the true facts or not he did not rely on the representation.
4. The representation need not be the sole inducement. It is sufficient so long as it plays some part even if only a minor part in contributing to the formation of the contract."
54 In particular the plaintiffs claimed that Santow J failed to consider whether Mr Wilson's representations played some part, even if only a minor one, in contributing to the formation of the contract. The plaintiffs gave no evidence that they did. Counsel referred us to passages in Mr Mahlo's evidence where he said that he told his wife that the bank manager had suggested to him that they should consider purchasing 'Allawah' to make their operation more viable, that they should get bigger or get out and that, with the security that the bank manager indicated, it would be a good idea. However, Santow J was not satisfied on the evidence that the idea for the purchase was Mr Wilson's and that the Mahlos were encouraged by him to make a decision which was not their own. More than once his Honour expressed his satisfaction that Mr Mahlo had made his own decision to purchase 'Allawah'. This seems to me only consistent with the conclusion that whatever Mr Wilson may have said about the desirability of making the purchase or about interest rates, wheat prices, property values or security, played no part in inducing the plaintiffs to purchase 'Allawah'.
55 In San Sebastian Pty Limited v The Minister (1986) 162 CLR 340 at 355 Gibbs CJ, Mason, Wilson and Dawson JJ referred to the relationship of proximity as an integral constituent of the duty of care concept embracing a general limitation upon the test of reasonable foreseeability of vital importance when the plaintiff's claim is for pure economic loss. Nevertheless, proximity was not thought by all members of the Court capable of constituting a universal criterion of liability; see per Brennan J, as his Honour then was, at 368-9. In Perre v Apand Pty Limited (1999) HCA 36 (12 August 1999) at 74 McHugh J, after referring to the speech of Lord Oliver in Murphy v Brentwood District Council [1991] 1 AC 398 at 487 and the necessity to find something more than the mere occurrence of economic loss and the fact that its occurrence could be foreseen, said:
"For some years in this Court, the 'something more' was 'proximity' which Deane J suggested in Jaensch v Coffey (1984) 155 CLR 549 at 584 'involves the notion of nearness or closeness'. However, this Court no longer sees proximity as the unifying criterion of duties of care; Hill v Van Erp (1997) 188 CLR 159 at 176-177, 210 and 237-239; Pyrenees Shire Council v Day (1998) 192 CLR 330 at 414. The reason that proximity cannot be the touchstone of a duty of care is that it 'is a category of indeterminate reference par excellence': McHugh 'Neighbourhood Proximity and Reliance' in Finn (ed) Essays on Torts (1989) 5 at 13, also 36-39; see also Stapleton 'Duty of Care Factors: A Selection from the Judicial Menus' in Cane & Stapleton (eds) The Law of Obligations - Essays and Celebration of John Fleming (1998) 59 at 60-62."
56 But as Gleeson CJ pointed out at 5 there remains a need to constrain a duty to avoid any reasonably foreseeable financial harm by "some intelligible limits to keep the law of negligence within the bounds of commonsense and practicality"; Caparo Industries plc v Dickman [1990] 2 AC 605 at 633 per Lord Oliver of Aylmerton; see also Caltex Oil (Australia) Pty Limited v The Dredge 'Willemstad' (1976) 136 CLR 529 at 573 per Stephen J.
57 At 27 Gaudron J said:
"It may well be that, at this stage, the notion of proximity can serve no purpose beyond signifying that it is necessary to identify a factor or factors of special significance in addition to the foreseeability of harm before the law will impose liability for the negligent infliction of economic loss."
58 At 93 McHugh J said:
"If a case falls outside an established category, but the defendant should reasonably have foreseen that its conduct would cause harm to the plaintiff, we have only to ask whether the reasons that called for or denied a duty in other (usually similar) cases require the imposition of a duty in the instant case. ………But in an area of law such as awarding damages for negligently inflicted economic loss, which is still developing and which has been recently cast adrift from any unifying principle, there is no alternative to a cautious development of the law on a case by case basis. Perhaps another unifying principle may emerge and gain widespread acceptance."
59 At 201 Gummow J said:
"I prefer the approach taken by Stephen J in Caltex Oil . His Honour isolated a number of 'salient features' which combined to constitute sufficiently close relationship to give rise to a duty of care owed to Caltex for breach of which it might recover its purely economic loss. In Hill v Van Erp and Pyrenees Shire Council v Day , I favoured a similar approach, with allowance with for the operation of appropriate 'control mechanisms'."
60 At 333 Hayne J said:
"It is because of the lack of definition of terms like 'proximity' and 'fairness' that it has been said that the law in this area should develop incrementally. And so it must for as long as no unifying principle emerges. But that is far from saying that the law should develop without explicit recognition of the factors that are considered important in deciding whether there is a duty to take care to avoid pure economic loss. The identification of those factors is essential to any ordered development of the law in this area."
61 At 406 Callinan J said:
"I turn now to a consideration of the factors which in combination I think relevant in this case and which establish a sufficient degree of proximity, foreseeability, a special relationship, determinancy of a relative small class, a large measure of control on the part of the respondent, and special circumstances justifying the compensation of the appellants for their losses."
62 Kirby J adhered to the criteria, expressed by him in Pyrenees Shire Council v Day at 419-420, of "foreseeability", "proximity" and competing "policy" to provide the answer, in a particular case, as to whether or not a duty of care existed in law giving rise to an entitlement to recover economic loss.
63 In the context of what was then thought to be the necessary relationship of proximity, the majority in San Sebastian Pty Limited v The Minister emphasised the role of inducement and reliance. Their Honours said at 355:
"When the economic loss results from negligent misstatement, the element of reliance plays a prominent part in the ascertainment of a relationship of proximity between the plaintiff and the defendant, and therefore in the ascertainment of a duty of care. ……
In cases of negligent misstatement, reliance plays an important role, particularly so when the defendant directs his statement to a class of persons with the intention of inducing members of the class to act or refrain from acting, in reliance on the statement, in circumstances where he should realise that they may thereby suffer economic loss if the statement is not true."
64 Though the concept of proximity is no longer to be regarded with foreseeability as a touchstone of liability, inducement combined with reliance continues to play an important role and remains a factor of special significance in determining whether liability for negligent misstatement will be imposed. But in the present case there was nothing to suggest that Mr Wilson intended to induce the plaintiffs to purchase the property. He denied that he had sought to influence them and accepted that in the economic climate it would have been reckless to do so. This perhaps throws up one aspect of the distinction between an actionable misrepresentation and a mere statement of opinion in the course of business negotiations.
65 Santow J found on the evidence that Westpac was under no duty to advise the appellants on the merits of the purchase. That conclusion was open to his Honour. It was open on the evidence for his Honour to conclude that nothing Mr Wilson said, in the context in which he said it, gave rise to such a duty and, equally, that nothing Mr Wilson said about the merits of the acquisition played any part in inducing the plaintiffs to go ahead with it. No representation made by Mr Wilson was intended to induce the plaintiffs to buy 'Allawah'. Accordingly, the decision to enter into the contract gives rise to no inference of inducement. None of the plaintiffs gave evidence of inducement. Moreover, there was no finding and apparently no evidence that any statements Mr Wilson made about future interest rates and wheat prices were not perfectly reasonable opinions to hold at the time.
66 In my opinion the appeal based on the plaintiffs' claim that Westpac gave the plaintiffs negligent advice fails.
