At the conclusion of these exchanges the member ruled that he was not disqualified from hearing the case on account of bias. The review then proceeded. The applicant gave his evidence through an interpreter. Mr White was called to give evidence. His report was tendered and he was asked questions by both the solicitor and by the member about its contents and about other matters as well. When the evidence had been taken the solicitor again took up his complaint about the bias of the member. This time Mr White became involved in the discussion. This was most unsatisfactory. The applicant, who had been listening through his interpreter, intervened and said: "I am sure that this case will be rejected. The issue has got off track. If you ever hear that I have committed suicide in the future, you are the responsible person."
The applicant's prediction turned out to be correct. On 27 November 1996 the Tribunal confirmed the decision of the delegate of the Minister not to grant the applicant a protection visa. Conformably with the Migration Act reasons for that decision were given. In those reasons the Tribunal referred extensively to the evidence given by Mr White and summarized a good deal of it. Some of his evidence was contrasted with other evidence before the Tribunal. Reference was made to Mr White's inability to provide information in answer to questions put to him by the Tribunal. Then there appears the following passage:
"Of course, it does not follow that gaps in his knowledge inevitably leads to the conclusion that he is not an expert in Alevi matters for the purposes of this particular case, and the Tribunal has referred above to information he has provided that is both valuable and, in some instances, is reflective of information from other sources. However, regardless of whether or not he is an expert on Alevi matters, and after taking all of the information into account, the Tribunal finds that his conclusion that all Alevis except those who have been co-opted by the Turkish government are at a real risk of persecution is not supported by other country information from a variety of sources or by the Applicant's personal experiences. Indeed, the information on which he relies, while demonstrating some persecution of Alevis, does not support his conclusion. It shows that there are isolated incidents from time to time that sometimes have the most grave consequences for a small number of Turkey's 20 million Alevis, but it does not support a conclusion that the Applicant faces a real chance of persecution because he is an Alevi."
This sufficiently deals with the facts. I now turn to discuss the manner in which the applicant brings the matter before the Court. Section 476(1) of the Migration Act provides the grounds upon which a decision of the Tribunal may be reviewed. In his application for review the applicant relies on a number of grounds, two of which are presently relevant. The first is that provided by s 476(1)(a) namely that the procedures required by the Migration Act to be observed were not observed. The procedures which it is alleged had not been observed are those imposed by s 420(2)(b). By s 420(2)(b) the Tribunal is obliged to act "according to substantial justice and the merits of the case". The applicant contends that one of the incidents of this obligation is to act without the appearance of disqualifying bias and this had not been complied with. The second ground is that provided by s 476(1)(f) namely that the decision of the Tribunal was induced or affected by actual bias.
It is apparent that if actual bias on the part of the Tribunal is established its decision can be set aside. It is not apparent that this will be so if apprehended bias is shown. Ultimately this will depend on the resolution of a number of different questions. The first is whether s 420(2)(b) imposes a procedural obligation to the effect that a member of the Tribunal must not sit when there is a reasonable apprehension of his or her bias. If it does, the second question is whether a breach of that obligation is reviewable under s 476(1)(a) notwithstanding the terms of
s 476(2)(a) which deny as a ground of review a breach of the rules of natural justice.
I have addressed some of the issues that arise in connection with these questions in Thambythurai & Anor v Minister for Immigration and Multicultural Affairs & Anor (Federal Court, unreported, 16 September 1997). I will not repeat what I said in that case. However, to understand what follows I will briefly state a number of the conclusions that I reached:
(i) s 420(2)(b) does impose an obligation of a procedural kind on the Tribunal; (ii) a decision arrived at in breach of that obligation is reviewable under s 476(1)(a); (iii) s 476(2) does not inhibit that review.
The difficult question here is whether the content of the obligation imposed on the Tribunal by s 420(2)(b) includes a requirement not to act when there is an appearance of disqualifying bias as has been contended by the applicant. In Thambythurai I explained that such an obligation would normally be imposed on a tribunal that was required to act in accordance with "substantial justice". I also indicated that the precise content of the obligation imposed by
s 420(2)(b) must depend upon an examination of all of the provisions of the Migration Act which confer powers on or regulate the activities of the Tribunal. It is now necessary to undertake that task.
The first section that is relevant is s 411 where the decisions that are reviewable by the Tribunal are set out. In substance they are decisions to refuse to grant or to cancel a protection visa. Thus the Tribunal is an essential part of the mechanism by which Australia carries out its obligations towards refugees as required by the Refugees Convention and the Refugees Protocol. Next there is s 420 itself. Sub-section (1) provides that the Tribunal's objective, in carrying out its functions, is to be "fair, just, economical, informal and quick". This instruction, in combination with the language of s 420(2)(b), certainly suggests that the Tribunal is required to conduct itself in a way that persons who are affected by its decisions, as well as persons who observe the performance of its functions, can be satisfied that the Tribunal is unbiased and that it appears to be unbiased. This is so that parties as well as the public will have confidence in the administration of justice through the medium of the Tribunal. Then there is s 467. It provides that a member who has a conflict of interest in relation to a review must disclose that conflict and not take part in the review without obtaining the consent of the Principal Member or the Minister (as the case requires) as well as the consent of the applicant. Section 467(2) provides that there will be a conflict of interest where "a member has any interest, pecuniary or otherwise, that could conflict with the proper performance of the member's functions in relation to that review". Bias, whether real or apprehended, often results from a conflict of interest. By enacting s 467, the Parliament has taken a significant step towards ensuring that a member who sits will be free from the taint of bias. However, as I will later show, actual bias and apprehended bias can arise in circumstances far removed from any conflict of interest.
The next relevant section is s 476(1)(f) by which actual bias is made one of the prescribed grounds of review. The obvious point to note is that this ground is confined to actual bias and does not encompass apprehended bias. The other point to note is that while actual bias is made a ground of review it is by no means clear what constitutes the source of the obligation to act without bias. There is no express obligation to be found in the Migration Act requiring the Tribunal to act without bias. In the absence of an express stipulation it seems to me that there are three possible sources for the duty. First, the obligation may be implicit in the Migration Act itself: more correctly in Part 7 of the Migration Act. It will be recalled that in Salemi v McKellar No. 2. (1977) 137 CLR 396 the High Court held that an exercise of power by the Minister for Immigration under s 18 of the Migration Act to deport the appellant was not dependant on the observance of natural justice (which incorporates the rule against bias) because, as a matter of the construction of the statute, no such obligation was imposed. However, by the time FAI Insurances Ltd v Winneke (1982) 151 CLR 342 came to be decided the obligation to accord natural justice no longer depended on the construction of a statute. Natural justice was recognised as an entrenched common law right, absent a clear statutory intent to exclude it. So, ordinarily, it would be unlikely that the source of the obligation is an implication in the statute. The second possible source is the common law. This would conform with the views of the High Court expressed in a series of cases since FAI Insurances, including Kioa v West (1985) 159 CLR 550, Haoucher v Minister for Immigration and Ethnic Affairs (1990) 169 CLR 648, Attorney-General (NSW) v Quin (1989-1990) 170 CLR 1and Annetts v McCann (1990) 170 CLR 596. However, section 476(2)(a ) provides that a breach of the rules of natural justice is not a ground of review of a decision of the Tribunal. If the common law rules of natural justice were the source of the obligation to act without bias there would be an inconsistency between s 476(1)(f) and s 476(2)(a) which, on the plain meaning of the opening words of s 476(1), namely that s 476(1) is "subject to sub-section (2)," would probably be resolved in favour of s 476(2)(a). Such a result is so plainly unintended that it is unlikely that the common law is the source of the obligation. The last possible source is s 420(2)(b). I think that this is the most likely source for two reasons. First, as I indicated in Thambythurai, an obligation to act "according to substantial justice and the merits of the case" would ordinarily have as an incident a requirement to act in accordance with the rules of natural justice. The second reason is the process of elimination I have undertaken. However, if I am wrong in this conclusion it would be necessary to hold that the obligation arose by implication from the statute.
Further, it seems to me that ss 420, 467, 476(1)(f) and 476(2)(a) demonstrate that it was the intention of the Parliament to impose as statutory obligations on the Tribunal only certain of the requirements of the common law rules relating to bias. Those obligations are (a) the principles relating to actual bias as imposed by s 420(2)(b) or as imposed by implication, and (b) the principles relating to apprehended bias in so far as they have been adopted by s 467. Apart from the operation of s 467, I am of the view that the principles of the common law relating to apprehended bias were not intended to apply to the Tribunal.
If the foregoing analysis is correct then whatever might be the scope of operation of
s 420(2)(b) it does not require the Tribunal to avoid the appearance of disqualifying bias. In other words, to construe s 420(2)(b) as imposing a procedural obligation on the Tribunal to avoid the appearance of disqualifying bias would not be consistent with the disclosed intention of Parliament. I should say that I do not regard this result as wholly unsatisfactory because "conflict of interest" is broadly defined in s 467(2). But its area of operation is still much narrower than the common law would require.
Having reached the conclusion that, on the proper construction of 420(2)(b), the obligation to act in accordance with "substantial justice" does not require the Tribunal to avoid the appearance of disqualifying bias, strictly it is unnecessary for me to deal any further with this part of the applicant's case. However, because it forms such a significant part of the applicant's claim and because I might be wrong in my view of s 420(2)(b) I propose to proceed on the assumption that the applicant's construction of s 420(2)(b) is to be preferred.
A general principle that applies to judges and administrative decision-makers alike was that stated by Lord Esher MR in Allinson v General Council of Medical Education and Registration [1894] 1 QB 750 at 758:
"In the administration of justice, whether by a recognised legal Court or by persons who, although not a legal public Court, are acting in a similar capacity, public policy requires that, in order that there should be no doubt about the purity of the administration, any person who is to take part in it should not be in such a position that he might be suspected of being biassed."
This had not always been so. When Blackstone published his Commentaries between 1765 and 1769 he wrote (Comm.vol iii at 361):
By the laws of England also, in the times of Bracton and Fleta, a judge might be refused for good cause; but now the law is otherwise, and it is held that judges and justices cannot be challenged. For the law will not hold a possibility of bias or favour in a judge, who is already sworn to administer impartial justice, and I whose authority greatly depends upon that presumption and idea."
Now however, the cases show that if a decision-maker is actually biased or if it can be "firmly established" that a reasonable observer might believe that the decision-maker will not approach his task fairly and with an unprejudiced mind, the decision-maker is disqualified from sitting: R v the Commonwealth Conciliation and Arbitration Commission; Ex parte The Angliss Group (1969) 122 CLR 546 at 553-54, R v Australian Stevedoring Industry Board; Ex parte Melbourne Stevedoring Co Pty. Ltd. (1953) 88 CLR 100 at 116.
There are very few cases in the law reports where a finding of actual bias has been made against a judge. This no doubt reflects well on our system of justice. To some extent, however, it is also a reflection of the fact that where a finding of presumed or constructive bias can be made there is no need to consider the much more serious allegation of actual bias. Where the courts have considered the question of actual bias the focus of the enquiry has been whether the decision-maker has brought a "closed mind" to the enquiry: see for example Re Gooliah and Minister for Immigration and Citizenship 63 DLR (2d) 224 at 229 and Vakauta v Kelly (1989) 167 CLR 568 at 576. There are conflicting decisions on what needs to be shown to establish that a decision-maker has a "closed mind". One view is that expressed by Devlin LJ in R v Barnsley Licensing Justices; Ex parte Barnsley and District Licensed Victuallers' Association [1960] 2 QB 167. His Lordship said at 187 that:
"[t]he court might come to the conclusion that there was such a likelihood [of bias] without impugning [the statement of the decision maker] that he was not in fact biased. Bias is or may be an unconscious thing and a man may honestly say that he was not actually biased and did not allow his interest to affect his mind, although, nevertheless, he may have allowed it unconsciously to do so".
This passage was cited with approval by Lord Goff in R v Gough [1993] AC 646 at 659. On this view actual bias need not be wilful. Another view is that to make out a case of actual bias it is necessary to show that the decision-maker's mind was intentionally closed. Support for this approach is found in Anderton & Ors v Auckland City Council & Anor [1978] 1 NZLR 657 at 687 where Mahon J said:
"A party attacking a decision, or seeking prohibition against pending adjudication, may prove actual bias. The relative infrequency of decisions upholding this allegation is explicable, as already indicated, by the firm mandate of juristic policy that an inquiry into judicial motivation is undesirable. Actual bias entails, as a necessary ingredient, the operation of unlawful motive or intent in reaching the decision, and the objective presence of that likelihood exonerates the reviewing tribunal from any determination as to whether the adjudication is disqualified for actual bias or whether the decision was controlled by that vitiating factor. But actual bias may be alleged and proved." (citations omitted)
It is hard to see why this approach is correct. I accept that most often actual bias will result from an intentional state of mind. But this will not always be so. For so long as the possibility exists that bias may be unconscious there is no reason in principle why a claim should not succeed in that circumstance. The wrong involved is the failure to decide a case impartially. Whether that failure was deliberate or not should be beside the point in so far as the validity of the decision is concerned.
Constructive or apprehended bias is of a very different character. It does not depend at all on the state of mind (whether conscious or unconscious) of the decision-maker. It is concerned with appearances - that is, the appearance of justice being done: R v Sussex Justices; Ex parte McCarthy [1924] 1 KB 256 at 259. Constructive or apprehended bias can arise in many different circumstances. One clear example is that of a pecuniary interest in the outcome of a case: Dimes v Grand Junction (1852) 3 HLC 759 where an order was set aside because the Lord Chancellor was a shareholder in the company concerned. Another example is that described as "incompatibility" by Isaacs J in Dickason v Edwards (1910) 10 CLR 243 at 259. It arises when the decision-maker has some other position in the case. A common instance would be where the decision-maker is officially connected with a party. Another example is where there is a relationship, of friendship or otherwise, between the decision-maker and a party: Ex parte Blume; Re Osborn (1958) 58 SR (NSW) 34 where there was a close friendship between a judge and a party's spouse. Another example again, and the one with which we are concerned in this application, is what has been called predetermination or prejudgment. By this I mean the situation where, as a result of earlier events, a decision-maker has formed views about an issue of law or fact that will arise for his or her determination. It is not surprising that this situation frequently occurs. Now the legal implications need to be explored.
What the cases establish is that ordinarily prejudgment or predetermination alone will not be a disqualifying factor. Something more must be shown. Usually what must be shown is that there is a reasonable apprehension that the decision-maker will not alter his or her preconceived position regardless of the evidence that may be led. Mason J explained this in Re JRL; Ex parte CJL (1986) 161 CLR 342 at 352:
"It needs to be said loudly and clearly that the ground of disqualification is a reasonable apprehension that the judicial officer will not decide the case impartially or without prejudice, rather than that he will decide the case adversely to one party. There may be many situations in which previous decisions of a judicial officer on issues of fact and law may generate an expectation that he is likely to decide issues in a particular case adversely to one party. But this does not mean either that he will approach the issues in that case otherwise than with an impartial and unprejudiced mind in the sense in which that expression is used in the authorities or that his previous decisions provide an acceptable basis for inferring that there is a reasonable apprehension that he will approach the issues in this way. In cases of this kind, disqualification is only made out by showing that there is a reasonable apprehension of bias by reason of prejudgment and this must be 'firmly established'".
The same point was made in the joint judgment of Gaudron and McHugh JJ in Laws v Australian Broadcasting Tribunal (1990) 170 CLR 70 at 100 where their Honours said:
"A reasonable bystander does not entertain a reasonable fear that a decision-maker will bring an unfair or prejudiced mind to an enquiry merely because he has formed a conclusion about an issue involved in the inquiry ... When suspected pre-judgment of an issue is relied upon to ground the disqualification of a decision-maker, what must be firmly established is a reasonable fear that the decision-maker's mind is so prejudiced in favour of a conclusion already formed that he or she will not alter that conclusion irrespective of the evidence or arguments presented to him or her."(citations omitted)
Here the emphasis is on the partiality of the decision-maker not merely on the existence of a predetermined view. Partiality exists when the decision-maker has a closed mind because of his or her earlier views. But the facts must show a reasonable fear that the mind of the decision-maker is closed. However, there is one circumstance where little more would need to be shown than the fact that a judge or tribunal has formed a particular opinion as a result of an earlier case. That circumstance is where there has been an adverse view taken of the honesty or creditworthiness of a witness, at least an important witness, or a party. Then partiality will be presumed. Two decisions of the High Court should be referred to in this connection. The first is R v Watson; Ex parte Armstrong (1976) 136 CLR 248 where at 264 Barwick CJ, Gibbs, Stephen and Mason JJ said:
"As the cases show, there are some matters on which a judge may have pre-conceived opinions, and yet be qualified to sit, but speaking generally the credit of an essential witness, where the case may turn on credibility, is not one of them."
The second is Livesey v New South Wales Bar Association (1983) 151 CLR 288. There the High Court considered the case of the New South Wales Court of Appeal Division sitting on an application to strike a barrister off the roll. There was a possibility that a particular witness would give significant evidence on that application. Two members of the Court of Appeal had previously expressed "strong views that she was a witness without credit ... whose evidence should be rejected." In its joint judgment the High Court said at 294:
"(T)he question whether a judge who is confident of his own ability to determine the case before him fairly and impartially on the evidence should refrain from sitting because of a suggestion that the views which he has expressed in his judgment in some previous case may result in an appearance of pre-judgment can be a difficult one involving matters 'of degree and particular circumstances may strike different minds in different ways.'" (citation omitted)
Later the High Court said at 299-300:
"Necessity and the extraordinary case ... make it impossible to lay down an inflexible rule; each case must be determined by reference to its particular circumstances...
[A] fair minded observer might entertain a reasonable apprehension of bias by reason of prejudgment if a judge sits to hear a case at first instance after he has, in a previous case, expressed clear views either about a question of fact which constitutes a live and significant issue in the subsequent case or about the credit of a witness whose evidence is of significance on such a question of fact."
In the result the High Court was unanimous in holding that the two judges were disqualified from sitting. Somewhat similar facts were considered in Australian National Industries Ltd v Spedley Securities Ltd (in liq) and Ors (1992) 26 NSWLR 411. The collapse of the Spedley group led to a number of complicated actions being instituted in the Commercial Division of the Supreme Court. The cases were assigned to one judge in the expectation that a good deal of judicial time and costs would be saved. In deciding one action the judge was very critical of the honesty of a number of the directors of Spedley and was also critical of the conduct they engaged in. He was asked to disqualify himself from hearing any other case involving those persons. The Court of Appeal (by a majority of 3:2) held that the judge was disqualified on the basis that a suspicion of bias was inevitable having regard to the nature of his earlier findings: see especially Mahony JA at 441-442 and Meagher JA at 428. Later cases in New South Wales have doubted whether Spedley was correctly decided: see eg R v Masters (1992) 26 NSWLR 450. I have no doubt that on the facts of the particular case the Court of Appeal correctly applied the principles relating to apprehended bias.
There is a qualification that should be made to the proposition that if a view is held by a decision-maker about the reliability or honesty of a party or an important witness that alone will result in an apprehension of disqualifying bias. This qualification was noted by the High Court in Vakauta 167 CLR at 584-585. The issue that arose in that case was whether the preconceived views held by a trial judge about certain expert medical witnesses prevented that judge from hearing a case involving those witnesses. In that connection the High Court drew a distinction between expert and non-expert witnesses. Brennan, Deane and Gaudron JJ said at 571:
"Both necessity and common sense require that the distinction be drawn between the case where a judge has some pre-conceived views about the expertise or reliability or professional opinions of an expert medical witness and the case where a judge has pre-conceived views about the credit or trustworthiness of a non-expert witness 'whose evidence is of significance on ... a question of fact' which 'constitutes a live and significant issue' in the case."
The High Court drew this distinction for the very practical reason that it would become impossible for courts if a judge was disqualified from hearing a case merely because the judge held an adverse view about an expert witness. There are many areas of the law where a small number of expert witnesses regularly give evidence. It would not take too long before all decision-makers would be disqualified from sitting on a case involving those witnesses. But it is also correct to say, in my opinion, that although there will not be a reasonable apprehension of bias merely because a judge has expressed an adverse opinion about an expert witness, the manner and nature of the criticism, as well as the circumstances in which it is made, may well justify such an allegation. In other words a close examination of the facts and circumstances surrounding the formation of an adverse view about an expert witness may show a reasonable apprehension that the judge will not have an open mind towards the evidence that expert will give in a later case.
I think that another distinction should also be drawn. It is the distinction between the case where prejudgment is alleged against a judge or tribunal that is, by its constituting legislation, presided over by a person with legal training and that where prejudgment is alleged against a lay tribunal. Apprehended bias may be more easily made out, in my opinion, in the case of a lay tribunal than the case of a decision-maker whose legal training, experience and commitment to judicial office enable him or her to bring an unbiased mind to a case: see the comments of Toohey J in Vakauta at 585.
