The second issue: apprehended bias
39 There was no dispute between the parties as to the general principles applicable to a claim of apprehended bias. The test for apprehended bias in relation to curial proceedings is whether a fair-minded lay observer might reasonably apprehend that the judge might not bring an impartial mind to the resolution of the question to be decided: Ebner v Official Trustee in Bankruptcy (2000) 205 CLR 337 at [6] per Gleeson CJ, McHugh, Gummow and Hayne JJ; Johnson v Johnson (2000) 201 CLR 488 at [11] per Gleeson CJ, Gaudron, McHugh, Gummow and Hayne JJ. In Re Refugee Review Tribunal; ex parte H (2001) 179 ALR 425, Gleeson CJ, Gaudron and Gummow JJ observed (at 27]) that that formulation "owes much to the fact that court proceedings are held in public. There is some incongruity in formulating a test in terms of 'a fair-minded lay observer' when, as is the case with the Tribunal, proceedings are held in private". Their Honours continued (at [28]-[29]):
28 Perhaps it would be better, in the case of administrative proceedings held in private, to formulate the test for apprehended bias by reference to a hypothetical fair-minded lay person who is properly informed as to the nature of the proceedings, the matters in issue and the conduct which is said to give rise to an apprehension of bias. Whether or not that be the appropriate formulation, there is, in our view, no reason to depart from the objective test of possibility, as distinct from probability, as to what will be done or what might have been done. To do otherwise, would be to risk confusion of apprehended bias with actual bias by requiring substantially the same proof.
29. Though the test in administrative proceedings, as in curial proceedings, is, in our view, one of objective possibility, the non-curial nature of the body or tribunal in question and the different character of the proceedings must, as already indicated, be taken into account. …
40 In Isbester v Knox City Council (2015) 255 CLR 135, Kiefel, Bell, Keane and Nettle JJ said (at [20]-[23]):
20 The question whether a fair-minded lay observer might reasonably apprehend a lack of impartiality with respect to the decision to be made is largely a factual one, albeit one which it is necessary to consider in the legal, statutory and factual contexts in which the decision is made.
21 The principle governing cases of possible bias was said in Ebner to require two steps to be taken in its application. The first requires the identification of what it is said might lead a decision-maker to decide a case other than on its legal and factual merits. Where it is said that a decision-maker has an "interest" in litigation, the nature of that interest must be spelled out. The second requires the articulation of the logical connection between that interest and the feared deviation from the course of deciding the case on its merits. As Hayne J observed in Jia Legeng, essentially the fear that is expressed in an assertion of apprehended bias, whatever its source, is of a deviation from the true course of decision-making.
22 It was observed in Ebner that the governing principle has been applied not only to the judicial system but also, by extension, to many other kinds of decision-making and decision-makers. It was accepted that the application of the principle to decision-makers other than judges must necessarily recognise and accommodate differences between court proceedings and other kinds of decision-making. The analogy with the curial process is less apposite the further divergence there is from the judicial paradigm. The content of the test for the decision in question may be different.
23 How the principle respecting apprehension of bias is applied may be said generally to depend upon the nature of the decision and its statutory context, what is involved in making the decision and the identity of the decision-maker. The principle is an aspect of wider principles of natural justice, which have been regarded as having a flexible quality, differing according to the circumstances in which a power is exercised. The hypothetical fair-minded observer assessing possible bias is to be taken to be aware of the nature of the decision and the context in which it was made as well as to have knowledge of the circumstances leading to the decision.

41 In Isbester, Gageler J said (at [57]):
The test for the appearance of disqualifying bias in an administrative context has often been stated in terms drawn from the test for apprehended bias in a curial context. The test, as so stated, is whether a hypothetical fair-minded observer with knowledge of the statutory framework and factual context might reasonably apprehend that the administrator might not bring an impartial mind to the resolution of the question to be decided. Such statements of the test have nevertheless been accompanied by acknowledgement that the application of this requirement of procedural fairness "must sometimes recognise and accommodate differences between court proceedings and other kinds of decision making".

42 The appellant's submissions in relation to the second issue can be summarised as follows.
(a) The circumstances which give rise to a reasonable apprehension of bias in this case are not limited to the mere fact of the matter having been remitted to the same Tribunal member who had rejected the appellant's claim the first time. Rather, it is the combined effect of remittal to the same member and the manner in which the member actually addressed the appellant's claims on the second occasion. To put it differently, the basis of the apprehension of bias is the manner in which the member addressed the appellant's claims in circumstances where those claims had already been the subject of a determination by the same member.
(b) Having a decision-maker consider and determine an issue upon which he or she has already expressed a firm opinion - much less made a final determination - is inherently fraught with risk. In the judicial context, it almost inevitably entails an apprehension of bias: Livesy v New South Wales Bar Association (1983) 151 CLR 288 at 300; British American Tobacco Australia Services Ltd v Laurie (2011) 242 CLR 283.
(c) It is accepted that different considerations apply in the Tribunal context, having regard to the more flexible and informal nature of the proceedings: Minister for Immigration and Multicultural Affairs v Jia Legeng (2001) 205 CLR 507 at [98]-[100], [181]; Ebner v Official Trustee in Bankruptcy (2000) 205 CLR 337 at [4]; Minister for Immigration and Citizenship v SZQHH (2012) 200 FCR 223 at [40]-[45]. That does not mean that grounds for apprehended bias are precluded when a matter is remitted to the same member; it just means that there may not necessarily be grounds for apprehended bias, depending on the circumstances of the case.
(d) The underlying concern in a case like the present is the difficulty that a person might have in departing from a previous clearly expressed view - "a recognition of human nature": British American Tobacco Australia Services Ltd v Laurie at [139]. That difficulty is no less present in the Tribunal context, notwithstanding that its legal significance can be tempered by the different nature of the decision-making paradigm: see, eg, Laws v Australian Broadcasting Tribunal (1990) 170 CLR 70 at 81-82, 91-92. The role of Tribunal members is not underpinned by the same constitutional and statutory safeguards which aid the avoidance of the appearance of prejudgment where judges are concerned: Vakauta v Kelly (1989) 167 CLR 568 at 584-585; Johnson v Johnson (2000) 201 CLR 488 at [12].
(e) The manner in which the Tribunal approached considering and expressing conclusions about risks the appellant would face in Karachi might give rise to a reasonable apprehension that it might have prejudged those questions. The basis for such an apprehension is captured most clearly, but by no means exclusively, in the Tribunal's use of language such as "the fact remains…", "still leads the Tribunal to consider …" and "However, the Tribunal does not consider these trends take place at a rate that would cause the Tribunal to depart from its view that the risk of the applicant suffering serious harm in Karachi is remote" (see the Second Tribunal Decision at [58], [61], set out above). When read in the context of the manner in which the issues were being considered and the conclusions expressed, these statements can be seen to be an accurate reflection of how the Tribunal was conducting its task, rather than a series of unfortunate turns-of-phrase.
(f) A fair reading of the Tribunal's reasons might easily give rise to an apprehension that the Tribunal had not freshly approached the question of risks the appellant would face in Karachi, but rather had treated its previous determination as an extant correct finding, and the fixed foundation for its second decision.
(g) An apprehension that the Tribunal had approached its task in such a manner is materially different from an apprehension that it had a mere 'predisposition' or 'tendency of mind', or that upon considering the appellant's claims afresh its reasoning might follow a path akin to that which it had previously followed. The Tribunal's mind is not required to be a blank sheet: Vakauta v Kelly at 575-576; Jia Legeng at [71]; SZQHH at [38]. What is required to be a blank sheet, and what a fair-minded and reasonably well-informed observer might apprehend might not have been treated as a blank sheet, is the Tribunal's task of considering afresh all questions of fact and law relevant to the appellant's claim for protection.
(h) The Tribunal's approach suggests a failure to appreciate the nature of its task on remittal. Its reasons reveal no process of starting afresh - rather, they are consistently expressed in a manner that might reasonably be apprehended as a continuation of its first decision. It is likely that the judge below also recognised the Tribunal's reasons as appearing to be a continuation of its first decision - relying as his Honour did (at [40]) on the Minister's submission that "the Act authorises the Tribunal to continue to review the decision to conclusion, even though the particular member has determined the matter previously". The case cited in support of that proposition (Applicant NAFF of 2002 v Minister for Immigration and Multicultural and Indigenous Affairs (2004) 221 CLR 1 at [26]-[27]) refers to s 414(1) of the Migration Act and says nothing about the proper approach where a matter has been remitted. To interpret it as requiring or allowing the Tribunal to treat its task on remittal as being to "continue … to conclusion" a decision which has been quashed runs contrary to what the High Court stated in Minister for Immigration and Multicultural Affairs v Wang (2003) 215 CLR 518 to be the effect of an order quashing a decision and remitting it for redetermination. In that case, Gummow and Hayne JJ said (at [67]): "The Court's orders, taken as a whole, provided for the Tribunal to begin again in its statutory task of reviewing the decision to refuse the respondent a protection visa" (emphasis added); see also [6]-[7] per Gleeson CJ. The same authority also makes clear why, in the context of the Tribunal's task, treating a review as a "continuation" of a quashed decision rather than one which it is "to begin again" is a matter of substance and not just form.
(i) Where the Tribunal has made a legal error - in the present case, by considering the reasonableness of relocation by reference to a narrow subset of potential risks that the applicant would face in Karachi - it is not possible to neatly disentangle the factual basis of the Tribunal's first decision from the applicable legal principles upon which that decision was founded, in error.
(j) A fair-minded and reasonably well-informed observer might reasonably apprehend that the Tribunal's factual enquiry in the present case had been skewed by the treatment of its task as a continuation of its first decision, and its previous findings as to the risks the appellant would face in Karachi as a fixed point of reference upon which to conduct that task - rather than as part of a decision which had been founded on a wrong legal principle and quashed at law.
(k) The circumstances which give rise to an apprehension of bias are not simply the remittal of the matter to the same Tribunal member, but the manner in which the Tribunal actually performed its task in circumstances where it had made previous findings on important facts in issue. The appellant could not waive his right to rely upon an apprehension of bias which was not apparent until the Tribunal made its decision and published its reasons: Vakauta v Kelly at 577-579, 587-588.
43 Although the appellant does not rely solely on the fact that the same member heard the matter on the second occasion, it is important to note that the appellant was on notice that the same member would be hearing the matter and did not object to that member hearing the matter. The letter dated 18 November 2013 to the appellant's solicitors and registered migration agent (referred to in paragraph [18] above) gave notice of the name of the member who would be hearing the matter on the second occasion. This member named was the same member as had heard the matter on the first occasion. No objection was taken either before or at the hearing to this member hearing the matter. If this were the only basis for the apprehended bias contention, the appellant would be taken to have waived his right to object (on the ground of apprehended bias) to the same Tribunal member hearing the matter on the second occasion: Vakauta v Kelly at 577-578 per Dawson J; Michael Wilson & Partners Limited v Nicholls (2011) 244 CLR 427 at [76] per Gummow ACJ, Hayne, Crennan and Bell JJ.
44 However, the appellant relies both on the fact that the same member heard the matter and on the contents of the Second Tribunal Decision to contend that a fair-minded lay observer might reasonably apprehend that the Tribunal member might not have brought an impartial mind to the resolution of the question to be decided. It is apparent from this description of the appellant's contention that it involves looking back ("might not have brought") rather than, as is usually the case in connection with apprehended bias, looking forward ("might not bring"). The appellant's contention also relies on the wording of the decision of the Tribunal to seek to establish apprehended bias by way of prejudgment. In Michael Wilson & Partners Limited v Nicholls, Gummow ACJ, Hayne, Crennan and Bell JJ said (at [67]):
As pointed out earlier in these reasons, an allegation of apprehended bias requires an objective assessment of the connection between the facts and circumstances said to give rise to the apprehension and the asserted conclusion that the judge might not bring an impartial mind to bear upon the issues that are to be decided. An allegation of apprehended bias does not direct attention to, or permit consideration of, whether the judge had in fact prejudged an issue. To ask whether the reasons for judgment delivered after trial of the action somehow confirm, enhance or diminish the existence of a reasonable apprehension of bias runs at least a serious risk of inverting the proper order of inquiry (by first assuming the existence of a reasonable apprehension). Inquiring whether there has been "the crystallisation of that apprehension in a demonstration of actual prejudgment" impermissibly confuses the different inquiries that the two different allegations (actual bias and apprehended bias) require to be made. And, no less fundamentally, an inquiry of either kind moves perilously close to the fallacious argument that because one side lost the litigation the judge was biased, or the equally fallacious argument that making some appealable error, whether by not dealing with all of the losing side's arguments or otherwise, demonstrates prejudgment.
(Footnote omitted, bold emphasis added.)
45 We do not read the above as precluding reliance on reasons for decision in support of an argument of apprehended bias. For example, the reasons for decision may record some aspect of the conduct of the hearing and be relied upon as evidence of that conduct. Or they may disclose some fact not previously known to the parties which supports an allegation of apprehended bias. However, as the above passage makes clear, one needs to be careful not to invert the proper order of inquiry by first assuming the existence of reasonable apprehension.
46 In Vakauta v Kelly, the High Court held that the observations made about the doctor in the course of the judgment amounted to ostensible bias because they would lead to the conclusion, in the mind of the reasonable or fair-minded observer, that the judge was heavily influenced by views he had formed on other occasions rather than by an assessment based on the case in hand: see at 573-574 per Brennan, Deane and Gaudron JJ, at 579 per Dawson J, at 588 per Toohey J. This case makes clear that, in some circumstances, apprehended bias may arise or be apparent from reasons for decision.
47 In the present case, and having regard both to the fact that the same member heard the matter and the content of the reasons for decision, we do not think a fair-minded lay observer might reasonably apprehend that the Tribunal member might not have brought an impartial mind to the resolution of the issue to be determined (namely, the relocation issue). While it is true that the Tribunal member referred on a number of occasions in the Second Tribunal Decision to the earlier decision, this was only natural in circumstances where he had decided the matter on the first occasion. It would have been artificial to have considered the matter without reference to the earlier decision and the reason why the Federal Circuit Court had overturned that decision and remitted the matter for reconsideration. However, the Tribunal member did refer to updated country information which makes clear that he was cognisant of the need to consider the matter afresh. Further, the Tribunal's statement of the relocation issue in paragraph [43] of the Second Tribunal Decision (quoted in paragraph [20] above) indicates that this issue was being approached afresh in light of the First Federal Circuit Court Decision. The appellant particularly relies on certain statements in paragraphs [58] and [61] of the Second Tribunal Decision (being the emphasised words in those paragraphs in the quotation set out in paragraph [22] above). But when these emphasised passages are read in the context of the decision as a whole, we think they are in fact a reference to the views that the Tribunal expressed in paragraphs [45] and [46] of the Second Tribunal Decision rather than to views expressed in the First Tribunal Decision. In the last sentences of paragraphs [45] and [46] (quoted in paragraph [21] above), the Tribunal expressed a view that certain risks of harm were "remote". In paragraph [58], the Tribunal said that "the fact remains" and that a certain matter "still leads the Tribunal to consider that the risk of the applicant suffering serious harm in that city because of his religion is remote". We think the Tribunal was here referring back to the view expressed at the end of paragraph [45] of its reasons. Likewise, we think that the sentence in paragraph [61] of the Second Tribunal Decision that reads, "However, the Tribunal does not consider these trends take place at a rate that would cause the Tribunal to depart from its view that the risk of the applicant suffering serious harm in Karachi is remote" is referring back to the view expressed in paragraph [46] of that decision. Thus we do not think it correct to say that the Tribunal started with its first decision and then considered whether the position adopted in that decision should be departed from. Rather, the Tribunal considered the relocation issue afresh (this time addressing the matter, not just on the basis of Convention reasons, but more generally, as it was directed to do by the First Federal Circuit Court Decision).
48 For these reasons, the primary judge was correct to conclude that the contention of apprehended bias was not made out.
