Case: Ebner v Official Trustee [2000] HCA 63 ; (2000) 205 CLR 337
Outcome: applied
In Ebner v Official Trustee [2000] HCA 63 ; (2000) 205 CLR 337 at 344-345 [6] - [8] Gleeson CJ, McHugh, Gummow and Hayne JJ said: 'Where, in the absence of any suggestion of actual bias, a question arises as to the independence or impartiality of a judge (or other judicial officer or juror), as here, the governing principle is that, subject to qualifications relating to waiver (which is not presently relevant) or necessity (which may be relevant to the second appeal), a judge is disqualified if 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 (R v Watson; Ex parte Armstrong [1976] HCA 39 ; (1976) 136 CLR 248; Re Lusink; Ex parte Shaw (1980) 55 ALJR 12; 32 ALR 47; Livesey v NSW Bar Association [1983] HCA 17 ; (1983) 151 CLR 288; Re JRL; Ex parte CJL [1986] HCA 39 ; (1986) 161 CLR 342; Vakauta v Kelly [1989] HCA 44 ; (1989) 167 CLR 568; Webb v The Queen [1994] HCA 30 ; (1994) 181 CLR 41; Johnson v Johnson [2000] HCA 48 ; (2000) 201 CLR 488). That principle gives effect to the requirement that justice should both be done and be seen to be done (R v Sussex Justices; Ex parte McCarthy [1924] 1 KB 256 at 259, per Lord Hewart CJ), a requirement which reflects the fundamental importance of the principle that the tribunal be independent and impartial. It is convenient to refer to it as the apprehension of bias principle. The apprehension of bias principle may be thought to find its justification in the importance of the basic principle, that the tribunal be independent and impartial. So important is the principle that even the appearance of departure from it is prohibited lest the integrity of the judicial system be undermined. There are, however, some other aspects of the apprehension of bias principle which should be recognised. Deciding whether a judicial officer (or juror) might not bring an impartial mind to the resolution of a question that has not been determined requires no prediction about how the judge or juror will in fact approach the matter. The question is one of possibility (real and not remote), not probability. Similarly, if the matter has already been decided, the test is one which requires no conclusion about what factors actually influenced the outcome. No attempt need be made to inquire into the actual thought processes of the judge or juror. The apprehension of bias principle admits of the possibility of human frailty. Its application is as diverse as human frailty. Its application requires two steps. First, it requires the identification of what it is said might lead a judge (or juror) to decide a case other than on its legal and factual merits. The second step is no less important. There must be an articulation of the logical connection between the matter and the feared deviation from the course of deciding the case on its merits. The bare assertion that a judge (or juror) has an "interest" in litigation, or an interest in a party to it, will be of no assistance until the nature of the interest, and the asserted connection with the possibility of departure from impartial decision making, is articulated. Only then can the reasonableness of the asserted apprehension of bias be assessed.'
