rEASONABLE APPREHENSION OF BIAS
4 The test for apprehended bias was recently considered by the High Court in QYFM v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2023] HCA 15; 409 ALR 65 at [37] (Kiefel CJ and Gageler J), [67] (Gordon J), [221] (Gleeson J), [274] (Jagot J) which affirmed the test in Ebner v Official Trustee in Bankruptcy [2000] HCA 63; 205 CLR 337. Apprehended bias exists when "a fair-minded lay observer might reasonably apprehend that the judge might not bring an impartial mind to the resolution of the question the judge is required to decide".
5 The Ebner test comprises a two-step process. First, it calls for the identification of the factor which might lead a decision maker to determine the matter other than on its legal and factual merits. Secondly, the test refers to the identification of a logical connection between the relevant factor and the risk of the matter being decided other than on its legal and factual merits: Ebner at [8] (Gleeson CJ, McHugh, Gummow and Hayne JJ).
6 For a logical connection to be established per the second step of the test, there must be "a cogent and rational link between the association and its capacity to influence the decision": Aussie Airlines Pty Ltd v Australian Airlines Pty Ltd & Qantas Airlines Ltd (1996) 65 FCR 215 at 235.
7 Referring to the test as the "double might test", Charlesworth J in Burgess v Minister for Immigration & Border Protection (2018) 259 FCR 197 said at [35]-[36]:
The first "might" concerns the likelihood (to be assessed by the Court) of the lay observer forming the reasonable apprehension. The second "might" concerns the content of the apprehension itself. It concerns the assessment (notionally made by the lay observer) of the likelihood of the decision-maker having a foreclosed mind (as opposed to having a predisposed opinion) and so deviating from the course of deciding a case on its merits.
Judicial statements to the effect that an allegation of apprehended bias must be distinctly made and clearly established are not to be understood as altering the degrees of likelihood inherent in the test itself: see MZZXM v Minister for Immigration & Border Protection [2016] FCA 405 at [106] and the cases cited therein. Each "might" in the double might test connotes a degree of likelihood that is lower than that which may be required by the civil standard of proof in an ordinary fact-finding context. It must nonetheless be shown that the reasonable lay observer might apprehend that the decision-maker might have a foreclosed mind. It is not sufficient to demonstrate that the observer may have "a vague sense of unease or disquiet" on the question: Jones (as President of the Victorian Farmers Federation Chicken Meat Group) v Australian Competition and Consumer Commission (2002) 76 ALD 424 at [100] (Weinberg J).
8 In QYFM, it was accepted that a third step is required, namely a consideration of the reasonableness of the asserted apprehension of bias: [38] (Kiefel CJ and Gageler J), [67] (Gordon J), [225] (Gleeson J), [275] (Jagot J).
9 In Johnson v Johnson (2000) 201 CLR 488; [2000] HCA 48, the High Court considered that the reasonableness of any asserted apprehension of bias is adaptable to modern litigation practices. At [13], the High Court stated:
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. The rules and conventions governing such practice are not frozen in time. They develop to take account of the exigencies of modern litigation. At the trial level, modern judges, responding to a need for more active case management, intervene in the conduct of cases to an extent that may surprise a person who came to court expecting a judge to remain, until the moment of pronouncement of judgment, as inscrutable as the Sphinx. In Vakauta v Kelly Brennan, Deane and Gaudron JJ, referring both to trial and appellate proceedings, spoke of "the dialogue between Bench and Bar which is so helpful in the identification of real issues and real problems in a particular case." Judges, at trial or appellate level, who, in exchanges with counsel, express tentative views which reflect a certain tendency of mind, are not on that account alone to be taken to indicate prejudgment. Judges are not expected to wait until the end of a case before they start thinking about the issues, or to sit mute while evidence is advanced and arguments are presented. On the contrary, they will often form tentative opinions on matters in issue, and counsel are usually assisted by hearing those opinions, and being given an opportunity to deal with them.

10 A number of characteristics are attributed to the fair-minded lay observer which are summarised by Kiefel CJ and Gageler J in QYFM at [47] - [49] as follows:
Being "fair-minded", the observer "is neither complacent nor unduly sensitive or suspicious". Yet the observer is cognisant of "human frailty" and is all too aware of the reality that the judge is human. The observer understands that "information [as well as attitudes] consciously and conscientiously discarded might still sometimes have a subconscious effect on even the most professional of decision-making".
Being "lay", the observer "is not to be assumed to have a detailed knowledge of the law, or of the character or ability of a particular judge". Though the observer may be taken to understand that the judge, by reason of professional training and experience and fidelity to the judicial oath or affirmation, will have a greater capacity than most to discard "the irrelevant, the immaterial and the prejudicial" and to discharge the judicial function uninfluenced by past professional relationships, "the public perception of the judiciary is not advanced by attributing to the … observer a knowledge of the law and an awareness of the judicial process that ordinary experience suggests not to be the case". This indicates that the observer will see the person who is currently a judge as the person who was formerly an advocate and may be less inclined to dissociate the advocate from the cause advocated than would someone steeped in the adversary process with a cultivated sense of the ethics of the legal profession and the profundity of the judicial oath.
Nor is the observer so abstracted and dispassionate as to be insensitive to the impression that the circumstances in issue might reasonably create in the mind of the actual party who is asserting an apprehension of bias. The observer can be taken to appreciate that a party - especially an individual, and especially a non-citizen facing deportation on the basis of his conviction - might understandably experience a justifiable sense of disquiet in seeing his former prosecutor turn up as one of his judges.
