The Minister's submissions
34 The Minister accepts that the leading case on bias is the High Court's recent decision in CNY17. In addition, the Full Court of this Court has delivered judgments in a number of subsequent proceedings in which bias has been alleged. The Minister submits that the following core principles can be derived from the authorities:
(1) The applicable test for apprehended bias is whether a fair-minded lay observer might reasonably apprehend that the decision-maker might not bring an impartial mind to the resolution of the questions the decision-maker is required to decide: CNY17 at [17] (Kiefel CJ and Gageler J), [56] (Nettle and Gordon JJ), [132] (Edelman J); FSG17 v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2020] FCAFC 29; 274 FCR 456 (FSG17) at [32(b)]; MBJY v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2021] FCAFC 11 (MBJY) at [33]; BYX17 v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2021] FCAFC 41 (BYX17) at [3].
(2) The fair-minded observer is taken to know "the nature of the decision, the circumstances which led to the decision and the context in which it was made. The fair-minded lay observer has 'a broad knowledge of the material objective facts … as distinct from a detailed knowledge of the law or knowledge of the character or ability of the [decision-maker]'": CNY17 at [58]. Further, the fair-minded observer, "though not a lawyer, is taken to know both the nature of the decision-maker and the nature of the process that the decision-maker is required to undertake": MBJY at [33].
(3) The test involves two steps: identifying what it is that might lead a decision-maker to decide a case other than on its legal and factual merits; and secondly, articulating a logical connection between the identified thing and the feared deviation from deciding the case on its merits: CNY17 at [57] (Nettle and Gordon JJ), cited in BYX17 at [33]; MBJY at [35].
(4) Whether the fair-minded observer would apprehend bias will always be a factual assessment to be decided in the legal, statutory and factual context of the case: MBJY at [37], citing Isbester v Knox City Council [2015] HCA 20; 255 CLR 135 at [21] (Kiefel CJ, Bell, Keane and Nettle JJ); BYX17 at [35].
(5) An aspect of that context is the particular decision-maker in question. The "content as to what is expected of the decision-maker will often be different in the case of quasi-judicial proceedings compared to a person making a purely administrative decision": MBJY at [36], citing Hot Holdings Pty Ltd v Creasy [2002] HCA 51; 210 CLR 438 at [7].
(6) It is possible, in certain circumstances, for a fair-minded observer to apprehend a subconscious effect on the mind of a decision-maker even if material is consciously and expressly put aside: FSG17 at [32(d)]. This is an aspect of the application of the law to the context of the particular case.
(7) The question whether the reasons of the decision-maker may be taken into account in determining bias is complex: SZQYM v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2020] FCA 779; 169 ALD 579 at [106]. However, the current state of the law appears to be that:
at least where the complaint is of apprehended bias in relation to the decision to be made (rather than a complaint in relation to the process that was followed) the contents of a decision may be brought to account as part of the context in determining whether from the perspective of a fair-minded lay observer there was a reason why the decision may not be independent and impartial: MBJY at [50].
(8) It is possible for a departure from impartial decision-making to be established where the decision-maker is shown to have knowledge of a prejudicial but inadmissible fact or circumstance that gives rise to an apprehension of bias on the basis that the decision-maker will be influenced by that fact. This will depend on whether the material, in the context of the case, is of a kind that may affect the decision-maker, including subconsciously: Webb v The Queen (1994) 181 CLR 41 (Webb) at 74; CNY17 at [57], [70], [92], [134]; MBJY at [51].
(9) It is relevant and ameliorates the potential prejudicial effect of material if the decision-maker ventilated the material with the person at a hearing: FSG17 at [36] and [44]; Webb at 53. It is also relevant, though it cannot determine the issue, that the decision-maker expressly sets aside prejudicial material from consideration: FSG17 at [39]-[40].
(10) It is not sufficient to show simply that prejudicial and inadmissible material was before the decision-maker. Rather, it is necessary to show that the fair-minded observer might think that the decision-maker might lead to the decision-maker being influenced such as to depart from a neutral evaluation of the merits: MBJY at [52].
35 The Minister accepts that the 2018 Emails were prejudicial in character because they revealed that the appellant had been charged with serious sexual offences. The Minister also accepts that the material was not relevant to the Tribunal's task, because it was not part of the Tribunal's task to consider s 36(1C) in a review under Part 7. The Minister submits that, notwithstanding that mistake, there was no jurisdictional error, because the Tribunal ultimately made no finding on the s 36(1C) question.
36 The Minister submits that the material that was before the Tribunal would not lead a lay observer, in the circumstances of the present case, to consider that there might have been a subconscious effect on the mind of the Tribunal, leading to an apprehension of bias, for the following reasons.
37 First, the Minister submits that it is apparent from the Tribunal's decision that it raised the criminal charges with the appellant, and allowed him to respond to the material: see Exhibit A.1, being the transcript of the hearing before the Tribunal Member on 1 November 2018 (Tribunal Transcript) at pp. 21-22. The Minister submits that the ventilation of the prejudicial material at the hearing substantially reduces the risk of apprehended bias in the mind of the lay observer: FSG17 at [36]-[44]. The Minister submits that the Tribunal Transcript of the hearing makes plain that the Tribunal was interested in the outcome and the process in respect of the charges rather than the investigation itself.
38 Second, the Minister submits that the Tribunal expressly set aside the criminal charges material for the purpose of its decision. The Minister submits that the Tribunal stated at [27] of its Reasons that it made no findings about s 36(1C) of the Act and that the criminal charges material "does not form part of my reasons for making the decision in this review". The Minister submits that the Federal Circuit Court correctly accepted that the Tribunal "expressly disavowed" the material or expressly did not rely on the material: FCC Judgment at [40] and [41].
39 Third, the Minister submits that the Tribunal was abundantly clear about the material it had been given, its own actions after considering the material (conducting some limited further investigations), that it had raised the material with the appellant, why it considered the material to be relevant, and then why it had set the material aside from the decision. This transparency, the Minister submits, stands against any concern of unconscious influence of the material in the mind of the lay observer.
40 Fourth, the Minister submits that the statutory scheme in this case is important and stands against a finding of bias. The Minister submits that, in contrast to the statutory scheme in CNY17, in the present case, under Part 7, the Tribunal was obliged to hold a hearing and was obliged to put adverse information to the appellant. In this case, the appellant was able to present to the Tribunal whatever relevant evidence he wished. These features, in the Minister's submission, distinguish this case from CNY17 and reduce the risk of bias.
41 Fifth, the Minister submits that the nature of the decision-maker is relevant. The Minister submits that, as Allsop CJ noted in MBJY at [3]:
The Tribunal under its constitutive legislation is an independent quasi-judicial body of skill and stature. A fair-minded lay observer would be taken to appreciate such matters. The stature and independence of the Tribunal is a feature of importance in the review of, and public confidence in, Commonwealth decision making.

42 The Minister submits that the fact that it was the Tribunal making the decision in this case, by contrast with other cases, reduces the risk of bias.
