The law concerning the test to be applied when an application is made for a judge to recuse herself or himself is well established. It is sufficient for present purposes to refer to the following passage of the Victorian Court of Appeal in AJH Lawyers Pty Ltd v Careri:[10]
The relevant principles governing the issue of apprehended bias are well settled. Essentially, there are eight relevant principles.
...
Secondly, as noted in Antoun,[11] judges should not "too readily accept recusal because a party has demanded it".[12] Further, as held in Ebner,[13] "[j]udges have a duty to exercise their judicial functions when their jurisdiction is regularly invoked and they are assigned to cases in accordance with the practice which prevails in the court to which they belong. ... If one party to a case objects to a particular judge sitting, or continuing to sit, then that objection should not prevail unless it is based upon a substantial ground for contending that the judge is disqualified from hearing and deciding the case".[14] That being said, the principle that a judge should not disqualify him or herself too readily is not a "blanket that smothers the effect of disqualification where it has already arisen".[15]
Thirdly, the test for a reasonable apprehension of bias was stated in Johnson[16] as being "whether a fair-minded lay observer might reasonably apprehend that the judge might not bring an impartial and unprejudiced mind to the resolution of the question the judge is required to decide".[17] The word "might" in the phrase "might not bring an impartial and unprejudiced mind" was clarified in Ebner as referring to "possibility (real and not remote), not probability".[18] On the basis of Ebner, where, as in this case, "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".[19]
Fourthly, the apprehension in question is apprehension that the judge will not decide the case impartially, not merely an apprehension that he or she "will decide the case adversely to one party".[20]
Fifthly, the application of the test involves two steps. The first step is "the identification of what it is said might lead a judge ... to decide a case other than on its legal and factual merits".[21] The second step is the "articulation of the logical connection between the matter and the feared deviation from the course of deciding the case on its merits".[22] Contrary to AJH Lawyers' submission,[23] the two-step approach is applicable to cases of apprehended bias on the ground of prejudgment.[24] In such a case, the matter to be identified in the first step is the conduct of the judge said to give rise to apprehension of bias. And the logical connection that needs to be articulated in the second step is the logical connection between the conduct of the judge and the feared prejudgment of a question the judge is required to decide.[25]
Sixthly, "the perception of a lay observer will not be as informed as the perception of a lawyer, particularly a litigation lawyer".[26] The fictional lay observer "is not to be assumed to have a detailed knowledge of the law, or of the character or ability of a particular judge".[27] Yet the fictional observer is taken to understand the dynamics of modern judicial practice. Modern 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".[28] "[T]he expression of tentative views during the course of argument as to matters on which the parties are permitted to make full submissions does not manifest partiality or bias".[29]
Seventhly, "[a] line is drawn between forthright and robust indications of a trial judge's tentative views on a point of importance in a trial and an impermissible indication of prejudgment that has the effect of disqualifying the judge from further conduct of the proceedings".[30] A key factor determining whether that line has been crossed is the extent to which the views expressed by the judge appear to be final rather than merely tentative.[31]
Finally, ["j]udges do not have to devote unlimited time to listening to unmeritorious arguments. Sometimes, a brief hearing will suffice".[32] That having been said, when a party makes an application, the judge must normally give the party some reasonable opportunity to make submissions in support of that application.[33] This is so even if the judge's preliminary view is that the application will be unmeritorious.[34] If the judge refuses an application before receiving any submissions, the impression created by that conduct is not erased if the judge, after having announced his or her decision, agrees to listen to the party's submissions under sufferance.[35]
