B RELEVANT PRINCIPLES
7 This application brings into focus an issue which, at the margins, can have some complexity: that is, how one deals with apprehended bias in the context of interlocutory judgments.
8 As is well known, in its original jurisdiction, this Court follows a "docket system". The principle is that a matter is allocated to the docket of a particular judge at or about the time of its commencement, with the intention that, subject to any necessary reallocation, the proceeding will remain with that judge for the purposes of case management, determining any interlocutory applications, and eventual final disposition.
9 In my view, there are substantial advantages to the docket system over other systems of case allocation. It allows a single judge to case manage a dispute effectively and consistently with modern case management imperatives. It also allows a judge to acquire a familiarity with the underlying issues, which allows for the efficient identification and narrowing of the real issues required to be decided in order to quell the controversy: see Beaumont J, "Managing Litigation in the Federal Court" in Opeskin B and Wheeler F (eds), The Australian Federal Judicial System (Melbourne University Press, 2000) 160 (at 168).
10 Despite this, the docket system does have at least some potential disadvantages (even though these disadvantages are substantially outweighed by the advantages). There is always a risk that a judge who decides an interlocutory matter may appear to have prejudged issues or have been exposed to extraneous information in a way that may create an apprehension of bias, and therefore disqualifies the judge from further hearing the case. There is also a further risk that a judge who is intensely involved in the management of the case may lose the appearance of detachment traditionally associated with the judicial role, although, at least in my experience of the docket system, this might be regarded as a fairly remote and academic risk. A useful discussion of apprehended bias in the context of interlocutory judgments is provided by Ms Anna Olijnyk in "Apprehended Bias and Interlocutory Judgments" (2013) 35 Sydney Law Review 761, in which Ms Olijnyk draws attention to these risks (at 766).
11 One reason why the present difficulty does not often arise is that, in the vast bulk of cases, the resolution of interlocutory applications does not give rise to making factual findings following evidence challenged by cross-examination. As Bleby J explained in Southern Equities Corp Ltd (in liq) v Bond [2000] SASC 450; (2000) 78 SASR 339 (at 368 [129]):
[I]t should not be assumed that, merely because a judge has been responsible for the pre-trial case management of a particular case and will obviously have made decisions adversely affecting one party or another, the judge is necessarily precluded from conducting the trial. Indeed, there would be few interlocutory applications, a decision on which would be likely to give rise to a reasonable apprehension of bias. This is particularly so because most contested applications are decided on affidavit evidence where either the facts are not in dispute or where, as in the case of an interlocutory injunction, the judge merely has to be satisfied that the facts deposed to raise a serious question to be tried. Usually, findings on such issues will be cast in language which could not possibly found a successful submission of apprehension of bias.
12 But there will sometimes be cases, such as the present, where cross-examination, even relatively lengthy cross-examination, is appropriate to determine a contested issue. This is merely a particular instance of the more general notion that any discussion of apprehended bias requires close attention to the precise context and there is danger in generalising as to the application of principle. Every case must be considered by reference to its individual circumstances.
13 Recently, in the Australian Law Reform Commission's final report Without Fear or Favour: Judicial Impartiality and the Law on Bias (Report No 138, December 2021), the following was said in relation to allegations of pre-judgment arising from interim rulings (at [10.72], [10.77]):
10.72 The ALRC Case Review and comments to the ALRC Survey of Judges highlighted interim decisions against a party as the catalyst for a significant number of requests for disqualification. These objections are usually dismissed on the grounds that a judge deciding an issue against a party does not, without more, give rise to an apprehension of bias.
10.77 … given the prevalence of applications for disqualification related to interim rulings and interlocutory orders this would be an important area to consider addressing in each trial court's guidelines
In this area, at least three key principles are well established and often repeated in the case law:
• The fact that an order has been made against a party is not in itself a disqualifying ground [see Piepkorn v Caroma Industries Ltd [2000] FCA 1230 (at [10] per Wilcox J); Cavar v Greengate Management Services Pty Ltd [2016] FCA 961 (at [31] per Bromwich J); Callas v Callas [2018] FCCA 4 (at [148] per Judge Altobelli)].
• The expression of a tentative view by a judicial officer in the course of a hearing, in particular, a directions hearing, does not necessarily indicate that the judge has closed their mind [see Concrete Pty Ltd v Parramatta Design & Developments Pty Ltd [2006] HCA 55; (2006) 299 CLR 577 (at 610-611 [112]-[114] per Kirby and Crennan JJ); Johnson v Johnson [2000] HCA 48; (2000) 201 CLR 488 (at 493 [13] per Gleeson CJ, Gaudron, McHugh, Gummow and Hayne JJ). See further GlaxoSmithKline Australia Pty Ltd v Reckitt Benckiser Healthcare (UK) Ltd [2013] FCAFC 150 (at [43] per Allsop CJ, Middleton and Katzmann JJ)].
• A previous decision of the same fact or expression of clear views about the credit of a relevant witness, whether in the same proceedings or different proceedings, will amount to a disqualifying ground [see, for example, Jess v Jess (2021) 63 Fam LR 545 (at [396] per Alstergren CJ, Strickland and Kent JJ); Bob Jane Corporation Pty Ltd v ACN 149 801 141 Pty Ltd [2015] FCA 1343 (at [20]-[22] per Besanko J); British American Tobacco Australia Services Ltd v Laurie [2011] HCA 2; (2011) 242 CLR 283 (at 333 [145] per Heydon, Kiefel and Bell JJ); Livesey v New South Wales Bar Association (1983) 151 CLR 288 (at 300 per Mason, Murphy, Brennan, Deane and Dawson JJ); R v Watson; Ex parte Armstrong (1976) 136 CLR 248 (at 264 per Barwick CJ, Gibbs, Stephen and Mason JJ)].

14 There is no need for me to rehearse the authorities concerning the principles of apprehended bias at length. It seems to me that what is outlined above (at [10.77]), with reference to the authorities cited, is a useful summary of the current state of the law as to these principles as they apply to interlocutory matters.
15 It suffices to note that the general proposition is that the issue is to be determined by asking whether "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": Ebner v Official Trustee in Bankruptcy [2000] HCA 63; (2000) 205 CLR 337 (at 344 [6] per Gleeson CJ, McHugh, Gummow and Hayne JJ).
16 The only additional point I will make about the authorities is that there is an obvious tension, particularly evident in the present circumstances, between the duty to sit, which has been described "as equally strong as the duty to not sit where disqualified", and the concern about the cost, delay, reputational damage and inconvenience of an appellate court taking a different view from a primary judge as to whether they ought to have disqualified himself or herself: see Without Fear or Favour: Judicial Impartiality and the Law on Bias (at [7.20]); Laird v Tatum, 409 US 824 (1972) (at 837 per Rehnquist J).
17 Although a judge should not readily accede to an application for disqualification, the High Court has also said that there may be cases where the objection is substantial and it may be appropriate for the judge to disqualify himself or herself in a case of real doubt: Re JRL; Ex parte CJL (1986) 161 CLR 342 (at 352 per Mason J); Ebner (at 348 per Gleeson CJ, McHugh, Gummow and Hayne JJ).
