41 Their Honours also noted in Ebner (at [24]) that in Webb v The Queen (1994) 181 CLR 41 (at 74), Justice Deane had identified at least four distinct, though overlapping, categories of cases involving disqualification for apprehended bias: interest; conduct; association; and extraneous information. In fact, in Webb, Justice Deane extended the 'conduct' category to: 'conduct including published statements'. While not adopting this categorisation as comprehensive/exclusive in Ebner, their Honours considered it provided a convenient frame of reference. As an example of the overlaps that may occur, their Honours pointed to the categories of interest and association and referred to the House of Lords decision in R v Bow Street Magistrate; Ex parte Pinochet Ugarte (No 2)[2000] 1 AC 119 ('Pinochet') (at [28]). Nonetheless, while accepting that the overlaps between these categories will probably give rise to some debate on this aspect, the bias raised by the applicant in this case would appear to best fall within the 'published statements' extension of the 'conduct' category described in Webb.
42 In the course of the joint judgment in Ebner (at [9] and [10]), their Honours referred to the English Court of Appeal decision in Locobail (UK) Ltd v Bayfield Properties Ltd [2000] QB 451 ('Locobail') to make the point that the test for disqualification for bias (even though it is expressed somewhat differently in England) provides the most effective protection of the right to an impartial tribunal. Elsewhere in Locobail, the Court of Appeal set out a list of circumstances that it thought would, and would not, lead to disqualification for bias. While not ignoring the difference in the test for disqualification and noting the different social, political and constitutional circumstances in England (as to which, see: Thomas J B, Judicial Ethics in Australia (2nd edition) at pp 147 and 233 - 237), I believe this list of circumstances provides some helpful guidance on the sorts of circumstances that may, and may not, lend to disqualification for bias. The list of circumstances is as follows (at [25] of Locobail):
'Everything will depend on the facts, which may include the nature of the issue to be decided. We cannot, however, conceive of circumstances in which an objection could be soundly based on the religion, ethnic or national origin, gender, age, class, means or sexual orientation of the judge. Nor, at any rate ordinarily, could an objection be soundly based on the judge's social or educational or service or employment background or history, nor that of any member of the judge's family; or previous political associations; or membership of social or sporting or charitable bodies; or Masonic associations; or previous judicial decisions; or extra-curricular utterances (whether in textbooks, lectures, speeches, articles, interview, reports or responses to consultation papers); or previous receipt of instructions to act for or against any party, solicitor or advocate engaged in a case before him; or membership of the same Inn, circuit, local Law Society or chambers (see KFTCIC v Icori Estero Sp A. (Court of Appeal of Paris 28 June 1991, International Arbitration Report, vol. 6,8 8/91)). By contrast, a real danger of bias might well be thought to arise if there were personal friendship or animosity between the judge and any member of the public involved in the case; or if the judge were closely acquainted with any member of the public involved in the case, particularly if the credibility of that individual could be significant in the decision of the case; or if, in a case where the credibility of any individual were an issue to be decided by the judge, he had in a previous case rejected the evidence of that person in such outspoken terms as to throw doubt on his ability to approach such person's evidence with an open mind on any later occasion; or if on any question at issue in the proceedings before him the judge had expressed views, particularly in the course of the hearing, in such extreme and unbalance terms as to throw doubt on his ability to try the issue with an objective judicial mind (see Vakauta v Kelly (1989) 167 CLR 568); or if, for any other reason, there were real ground for doubting the ability of the judge to ignore extraneous considerations, prejudices and predilections and bring an objective judgment to bear on the issues before him. The mere fact that a judge, earlier in the same case or in a previous case, had commented adversely on a party or witness, or found the evidence of a party or witness to be unreliable, would not without more found a sustainable objection. In most cases, we think, the answer, one way or the other, will be obvious. But if in any case there is real ground for doubt, that doubt should be resolved in favour of recusal. We repeat: every application must be decided on the facts and circumstances of the individual case. The greater the passage of time between the event relied on as showing a danger of bias and the case in which the objection is raised, the weaker (other things being equal) the objection will be.' (My emphasis)
43 The words 'prejudices and predilections', that I have emphasised in the quote from Locobail (above), were also used by Justice Hayne in Minister for Immigration and Multicultural Affairs v Jia (2001) 178 ALR 421 to describe what is meant by 'bias' in this context, as follows (at [183], Gleeson CJ and Gummow J concurring at [100]):
"… it is necessary to consider more closely what is meant by 'bias' and 'apprehension of bias'. 'Bias' is used to indicate some preponderating disposition or tendency, a "propensity; predisposition towards; predilection; prejudice." It may be occasioned by interest in the outcome, by affection or enmity, or, as was said to be the case here, by prejudgment. Whatever its cause, the result that is asserted or feared is a deviation from the true course of decision-making, for bias is "any thing which turns a man to a particular course, or gives the direction to his measures."
44 Justice Hayne developed these concepts further at [185] - [186] as follows:
"Saying that a decision-maker has prejudged or will prejudge an issue, or even saying that there is a real likelihood that a reasonable observer might reach that conclusion, is to make a statement which has several distinct elements at its roots. First, there is the contention that the decision-maker has an opinion on a relevant aspect of the matter in issue in the particular case. Secondly, there is the contention that the decision-maker will apply that opinion to that matter in issue. Thirdly, there is the contention that the decision-maker will do so without giving the matter fresh consideration in the light of whatever may be the facts and arguments relevant to the particular case. Most importantly, there is the assumption that the question which is said to have been prejudged is one which should be considered afresh in relation to the particular case.
Often enough, allegations of actual bias through prejudgment have been held to fail at the third of the steps I have identified. In 1894, it was said that:
'preconceived opinions - though it is unfortunate that a judge should have any - do not constitute such a bias, nor even the expression of such opinions, for it "does not follow that the evidence will be disregarded." [emphasis added] (R v London County Council; Ex parte Empire Theatre (1894) 71 LT 638 at 639 per Charles J.)
Allegations of apprehended bias through prejudgment are often dealt with similarly."
45 Earlier, his Honour described the different constraints that apply to judicial decision-makers and the different circumstances in which they make their decisions as follows (at [178] - [179]):
'Courts in this country make decisions by procedures that are both formal and adversarial. They do so by the application of rules for decision-making which, although not always defined with absolute certainty, are generally discernible before the contest is joined and are set by legislative or judicial processes which are external to the judge. The process of adjudication is generally conducted in open court. The judge must give reasons for the decision that is reached.
Importantly, the rules about judicial prejudgment recognise that, subject to questions of judicial notice, judges, unlike administrators, must act only on the evidence adduced by the parties and must not act upon information acquired otherwise. No less importantly, the rules about judicial prejudgment proceed from the fundamental requirement that the judge is neutral. That requirement for neutrality is buttressed by constitutional and statutory safeguards. Those safeguards include not only the provisions for security of terms of office and remuneration but also extend to statutory provisions prohibiting interference with the course of justice. A judge can have no stake of any kind in the outcome of the dispute. The judge must not "[descend] into the arena and … have his vision clouded by the dust of the conflict.' The central task and, it may be said, the only loyalty, of the judge is to do justice according to law."
46 To my mind, the observations by the English Court of Appeal in Locobail and by Justice Hayne in Jia indicate that when an allegation of apprehended bias is based upon an expression of opinion by a judge, it is not so much that the opinion expressed may indicate some propensity, disposition or predilection on the judge's behalf that is critical. What is critical is that there is some real ground or real basis for concluding, in all the circumstances, that the judge will apply that opinion in the case at hand regardless of the facts and arguments presented in that case. Moreover, when the decision maker is a judge any consideration of this critical issue has to take account of the rules, processes and legal requirements that apply to the decision making role of all judges in Australia.
47 The High Court has also made it clear in a number of decisions before and after Ebner that apprehended bias must be 'firmly established': see The Queen v Commonwealth Conciliation and Arbitration Commission; ex parte Angliss Group (1969) 122 CLR 546 at 553 - 554, R v Lusink; Ex parte Shaw (1980) 32 ALR 47 at 50 - 51, Re JRL; ex parte CJL (1986) 161 CLR 342 at 532 and Re Minister for Immigration and Multicultural Affairs; ex parte Epeabaka (2001) 206 CLR 128 at 158.
48 As to the level of knowledge that the fair minded lay observer is imputed to have, in Johnson v Johnson (2000) 201 CLR 488 Chief Justice Gleeson and Justices Gaudron, McHugh, Gummow and Hayne observed (at [13]) that:
'Whilst the fictional observer, by reference to whom the test is formulated, is not to be assumed to have a detailed knowledge of the law, or of the character or ability of a particular judge, the reasonableness of any suggested apprehension of bias is to be considered in the context of ordinary judicial practice.'
49 Before that, in Laws v Australian Broadcasting Tribunal (1990) 170 CLR 70 at 87, Chief Justice Mason and Justice Brennan said:
'While it would not be proper to attribute to the fair minded observer the understanding that a lawyer would have of the capacity of the members of the Tribunal to make a independent decision uninfluenced by previously expressed opinions and conflicting interests (see Vakauta v Kelly (1989) 167 CLR 568), such an observer must be taken to appreciate that the defence filed by the Tribunal do not amount to assertions of belief or admissions.'
50 More recently, in Concrete Pty Ltd v Parramatta Design and Developments Pty Ltd [2006] HCA 55 at [177], Justice Callinan observed:
'It is axiomatic that the perception of a lay observer will not be as informed as the perception of a lawyer, particularly, a litigation lawyer. But the notional lay person should not be taken to be completely unaware of the way in which cases are brought to trial and tried.'
See also: Galea v Galea (1990) 19 NSWLR 263 at 279 per Kirby ACJ and Bowesco Pty Ltd v Zohar [2007] FCAFC 1 at [35] to [38].
51 Finally, on this aspect, Justice Lander provided, with respect, a good summary of most of these authorities in Australian Securities and Investment Commission v Reid [2005] FCA 1274 at [110] as follows:
'In summary, therefore, the inquiry is into the reaction of an observer who is reasonable and fair-minded, who has a general understanding of the facts and circumstances surrounding the case, who is not a lawyer but is not wholly uninformed and uninstructed about the law in general, and who would ordinarily think that a judge will act so as to ensure both the appearance and substance of fairness and impartiality without at the same time rejecting the alternative possibility. In a case such as this, the bystander will understand the Court's obligation which, if not maintained, will be enforced on appeal to act fairly and impartially.'
52 Albeit that it was delivered some 14 years before Ebner (but well after the first of the cases where the apprehension of bias principle was expounded), the examination of the connection between the identified cause of a possible disqualification and the issues that the judge or tribunal had to determine, was a matter that was considered by the Full Court of this Court in Attorney-General (NT) v Maurice (1987) 17 FCR 422. In that case an Aboriginal Land Commissioner ('the Commissioner') appointed under the Aboriginal Land Rights (Northern Territory) Act 1976 (Cth) ('the ALRA') was dealing with two Aboriginal land claims lodged under the ALRA - the Warumungu Land Claim and the Kenbi Land Claim. During the course of hearing the Warumungu Land Claim, the Commissioner made some comments that were highly critical of the Northern Territory Government. The Full Court described those comments in these terms: 'Statements and conduct [that] could reasonably be regarded as severely critical of the competence of the Northern Territory Government and as casting aspersions upon its integrity concerning its policies in relation to pastoral leases in the Northern Territory'(at 441).
53 With this in mind, the Full Court considered the issues that the Commissioner had to decide in each land claim to determine whether or not he should be disqualified for apprehended bias. In the Warumungu Land Claim, the Full Court held that the comments made by the Commissioner had no relevant bearing on the issues to be decided and that it could not be reasonably apprehended that the Commissioner might not resolve the issues before him in a fair and unbiased way (at 440 - 441). The Full Court therefore concluded that any evident attitude of the Commissioner's disaffection with the Northern Territory Government and its policies in relation to land tenure and other matters, could not, in its view, reasonably be said to call for the Commissioner's disqualification in that land claim (at 441).
54 The Full Court then considered the Kenbi Land Claim. It noted that in that land claim, the Commissioner had to embark upon an inquiry into the reasons why the Administrator of the Northern Territory made certain planning regulations under the Planning Act (NT) (No. 55 of 1999). In particular, the Commissioner had to determine whether the relevant regulation (Regulation 5) had been made for an improper purpose, namely of defeating the Kenbi Land Claim. The Full Court noted that in the process of making that determination, the Commissioner would be required to determine the bona fides of members of the Northern Territory Government in making the Cabinet decision which led to the making of the Regulation in question (at 441 - 442). Their Honours observed (at 442) that this issue was significantly different to the issues the Commissioner had to decide in the Warumungu Land Claim and ultimately concluded that the Commissioner should be disqualified from hearing the Kenbi Land Claim on the basis of the remarks he made about the Northern Territory Government because: "It might reasonably be apprehended by a fair-minded person that the Commissioner might not resolve the questions … relating to the validity of the Planning Regulations with a fair and unprejudiced mind."
55 In my opinion this decision provides a practical example of the application of the second step described in Ebner and the need, in that step, to look closely at the logical connection between the matter that is said to give rise to the concern about a lack of impartiality and the issues that have to be decided in the proceedings. Finally, I note that another, more recent, example of the application of the second step in Ebner is contained in the decision of Justice Tobias in City of Canada Bay Council v Bonaccorso Pty Ltd (No.2) [2007] NSWCA 368, particularly his Honour's conclusions at [17] and [18].
