Consideration
6 In my view, it is likely that the lay evidence of the witnesses called by each of the parties will take between four to six weeks for each of the sides; i.e. a total of between eight and twelve weeks. I accept that this is a broad-brush view. Nonetheless, given the intensity of the issues between the parties taken with the significant and large factual landscape that divides them, I think that it will be necessary for the parties to conduct extensive cross-examination of the principal lay witnesses for the purposes of making out or defending the substantive factual issues between them.
7 There will be some significant argument, which I deferred, over objections to expert evidence and there are other experts whose evidence must be given, albeit neither party anticipates that they will take a considerable time. Neither party is able to say whether, if a reference were ordered to commence on 4 June 2012, arrangements could be put in place to enable that to occur immediately. However, it may take no more than about a week to arrange a hearing room and other facilities so that the reference could run smoothly.
8 The premise upon which I had given my reasons on 24 May 2012 was that both sides opposed a hearing taking place next year and each had urged on 18 May 2012 that I retain the hearing date fixed, albeit opting for the different modes of trial, in Optiver's case before a judge, and the Tibra parties, before a referee or a judge. I discussed the potential consequences for the conduct of any hearing arising from the parties' claims for confidentiality in my earlier reasons.
9 The objectives of case management are stated in s 37M of the Federal Court of Australia Act 1976 (Cth), which I set out in my earlier reasons. They include the efficient use of the judicial resources available for the purposes of the Court and the efficient disposal of the Court's overall caseload (s 37M(2)(b) and (c)). The utilisation of an alternate mode of trial in the Court that s 54A now provides is a matter that the Court is entitled to consider. That is particularly so where a trial by a judge is likely to take an indeterminate time in excess of the parties' earlier estimates and other considerations do not suggest that a reference will not be an appropriate means to achieve the objectives in s 37M. One reason, in an appropriate matter, to make an order for reference under s 54A could be that there is a real likelihood that the hearing time for the matter would remove a judge from being able to hear other matters in his or her docket for a considerable and indeterminate time beyond an earlier agreed, but superseded, shorter hearing fixed in the Court: see Aon Risk Services Australia Limited v Australia National University (2009) 239 CLR 175 at 217-218 [111]-[114] per Gummow, Hayne, Crennan, Kiefel and Bell JJ.
10 It is not appropriate to allow the hearing fixed for eight weeks from 4 June 2012 to run on to its conclusion beyond the time the parties asked the Court to fix. The choices that I offered in my reasons of 24 May 2012 were predicated on the basis that both parties wanted a hearing to begin on 4 June 2012 but could not guarantee that it would conclude in the allotted time. If they could not agree to limit their cases so that it would, they could consent to an immediate reference or a hearing in 2013.
11 The issue now presented involves balancing the interests of justice between keeping the parties to a hearing commencing at a time they had both prepared for and urged, the impact of Dr Zobel's recently advised circumstances, the impact of further delay for the Tibra parties and the desire of Optiver, now, to adjourn the hearing before a judge until next year. While I am conscious that there is no certainty in Dr Zobel's view that he will be sufficiently recovered by about 27 August 2012, at the moment I think I must act on the basis that that is accurate. Optiver has only itself to blame for not raising this as an issue much earlier than it did. As it accepts, Dr Zobel's circumstances provide reason why it wishes to have the hearing date vacated. Any lack of certainty as to Professor Zobel's prognosis not being based on medical evidence must redound on Optiver.
12 In my opinion it is not desirable, in the interests of justice, to adjourn the hearing date for which the parties had prepared or to accede to Optiver's recent change of course, over the Tibra parties' opposition. As I have indicated, it is likely that, although these things cannot be predicted with precision, by the time Dr Zobel anticipates he will be recovered from his operation in late August 2012, a referee will be able to take his evidence concurrently with other experts. It may be that that is an underestimate because the cross-examinations of the lay witnesses may take longer than my current estimate and there may be some delays during the course of the reference.
13 Nonetheless, it seems to me that it is more in the interests of justice to have the parties start at the scheduled time for hearing for which they have prepared now and run it through to its conclusion before a referee than it is to delay the proceedings further so that it can be heard by a judge early next year. I am confident that the referee will be able to manage the proceedings efficiently and that the parties will accept that they are bound by the mode of trial that the Court has selected in doing so, including their obligations under Pt VB of the Federal Court of Australia Act.
14 For these reasons I will order that the proceedings be referred to a referee. It is necessary to make directions for the conduct of the reference.
