C.2 Adjournment or temporary stay
15 At first glance, it might be thought that the adjournment or temporary stay of the Martini proceeding creates no downside comparable to the increased costs of the counterfactual. Certainly, the consideration of the downside of adjourning the Martini proceeding requires close thought.
16 This is a case where no undertaking has been given on behalf of Boral to not relitigate common issues in the Martini proceeding, in circumstances where issues were determined adversely to it in the Parkin proceeding. The absence of this undertaking is perhaps unsurprising in the circumstances. Mr Darke SC, counsel for the applicant in the Martini proceeding, frankly conceded during the course of his submissions that, were there an adjournment or temporary stay ordered, the applicant in the Martini proceeding wishes to "keep up his sleeve" the prospect that he could seek to relitigate the common questions in the event that they were determined adversely in the Parkin proceeding: T31.33-42.
17 It is worth pausing for a moment to consider this issue from the perspective of both the group members and also a respondent, since this issue has not really been the subject of any extended examination in the authorities.
18 I have previously made reference in a number of judgments to what I have described as the pivotal provision in Pt IVA of the Federal Court of Australia Act 1976 (Cth) (Act), being s 33ZB. This provision creates a statutory estoppel binding group members to any judgment that has been made; including a determination of common issues.
19 Pt IVA more generally provides for an opt out regime. An applicant can commence a representative proceeding without the consent of a group member. The safeguard, however, is that a group member is entitled to be given adequate notice to make an informed decision about whether they wish for their claim to be determined in the representative proceeding, or rather wish to opt out. At least as a matter of legislative theory, the structure of Pt IVA provides that a group member is not placed in the position of having their rights determined in a case, in which they have had no involvement, and conducted by legal representatives they have had no involvement in selecting. It follows that Pt IVA, by its very nature, involves the prospect, at least in theory, that individuals who do not wish their claim to be determined in the class action may be able to relitigate issues in a different proceeding.
20 I raised with the parties during the course of oral argument whether a judgment made on the common issues could somehow operate in rem so as to bind group members, including by an order made under s 33ZF of the Act. However, having considered this prospect, I do not think that it is a possible option, particularly because of the structural aspects of Pt IVA to which I have already made reference. This would flow from the caution expressed in BMW Australia Ltd v Brewster [2019] HCA 45; (2019) 374 ALR 627 (at 643 [70] per Kiefel CJ, Bell and Keane JJ) that a provision such as s 33ZF cannot be used as a mechanism to rewrite the scheme of the legislation.
21 It might be thought to be a risk so minimal as to be fanciful that an individual group member would seek to relitigate common issues adversely determined after a long and complex initial trial, but as a matter of statutory construction, and subject to considerations I will deal with below, it is legally possible.
22 The position in relation to a respondent may not be entirely dissimilar but it is different. Stepping back for a moment, it is worth recalling that a fundamental tenet of the Australian legal system is that individuals claiming or denying the existence of a legal right should have an opportunity to be heard, but that access to justice cannot confer an unfettered licence to litigate. There must be limits. Public confidence in the courts, the proportionate use of public resources, finality in litigation, the scandal of inconsistent judgments, certainty of rights and the predictability of future outcomes all require there be an end to litigation. Duplicative relitigation is manifestly unfair and brings the administration of justice into disrepute: see O'Hara J, "Litigation preclusion: to what extent could (or should) a litigant be barred by prior litigation to which it was not a party?" (2018) 46(3) Australian Bar Review 286 (at 286).
23 In Kirby v Centro Properties Ltd [2008] FCA 1505; (2008) 253 ALR 65, Finkelstein J, in dismissing an application for a stay of proceedings and granting leave to file written submissions on the appointment of a litigation committee (which in the events that happened did not occur), dealt with a submission, coincidentally made by Freehills, that suggested their clients would be free to relitigate issues in another proceeding which went to trial. His Honour said the following (at 69-70 [16]-[18]):
16. Possibly Freehills was under the impression that if that action went against their clients they would be free to re-litigate the issues in the other action. If so, they may have been mistaken. For example, in England in Hunter v Chief Constable of the West Midlands Police [1982] AC 529; [1981] 3 All ER 727 (Hunter), the case involving the so-called "Birmingham 6", the House of Lords held that it was contrary to public policy and an abuse of process for a person to challenge in civil proceedings a decision which had gone against that person in a criminal case against which he had not appealed. Hunter and his co-accused had been convicted, wrongly as it turned out, of murder. They alleged at the trial that the confessions upon which their convictions were based were made as a result of threats and violence. The judge (wrongly as history shows) found that did not happen. The jury in any event convicted them. Subsequently Hunter sued the police officers for assault. His claim was struck out as an impermissible collateral attack on the findings made at the criminal trial. In Arthur JS Hall & Co v Simons [2002] 1 AC 615; [2000] 3 All ER 673, the House of Lords said that ordinarily the principles of res judicata and issue estoppel would be adequate to cover collateral challenges to civil decisions. But they said the Hunter abuse of process principle could be relied upon if necessary. It is not clear whether the Hunter principle will be applied in full in Australia: compare Rogers v R (1994) 181 CLR 251; 123 ALR 417; [1994] HCA 42 with D'Orta-Ekenaike v Victoria Legal Aid (2005) 223 CLR 1; 214 ALR 92; [2005] HCA 12. But it is unlikely that any court would permit a party to relitigate a question or issue which has already been decided against him even though the other side cannot strictly satisfy the requirements of res judicata or issue estoppel.
17. In the United States in Parklane Hosiery Co Inc v Shore 439 US 322 (1979) (Parklane), which was itself a class action case, the US Supreme Court held that the court has broad discretion to allow offensive, "non-mutual collateral estoppel" - that is, a plaintiff in a later action may, where it would promote judicial economy, consistency of result and would not otherwise be unfair, invoke issue estoppel against a defendant such as Centro to bar relitigation of an issue even if the plaintiff was not joined in the earlier action or in privity with a party to that action: Parklane at 329-31; see also V Morabito, "Defendant Class Actions and the Right to Opt Out: Lessons for Canada from the United States" (2004) 14 Duke J of Comp & Intl L 197, p 228 (collecting the US and Canadian authorities on "non-mutual collateral estoppel" or inherent jurisdiction to bar re-litigation of issues especially as applied in class actions).
18. Moreover, even if the principle identified in Parklane is not a part of the general doctrine of issue estoppel in Australia, I would certainly consider adopting it at least in the limited context of class actions, either pursuant to the court's authority under s 33ZF(1) of the Federal Court Act or possibly under the court's inherent jurisdiction to prevent an abuse of process. With respect to the latter, see Saffron v FCT (No 2) (1991) 30 FCR 578 at 583; 102 ALR 19 at 23 (Davies J), at FCR 588; ALR 28 (Lockhart J) and at FCR 599; ALR 37 (Beaumont J), where the Full Court suggested that while the Parklane principle was not a part of issue estoppel jurisprudence under Anglo-Australian law, it appeared to perform the same function and yield the same result as would obtain under the Australian abuse of process doctrine.
24 It seems to me that his Honour's comments need to be modified in the light of the High Court's comments in Brewster, but it is to be recalled that notions of justice and public confidence in the administration of justice must reflect contemporary values and must take into account the circumstances of a case, including the nature of representative proceedings.
25 In Rogers v The Queen (1994) 181 CLR 251, McHugh J stated (at 286):
Although the categories of abuse of procedure remain open, abuses of procedure usually fall into one of three categories: (1) the court's procedures are invoked for an illegitimate purpose; (2) the use of the court's procedures is unjustifiably oppressive to one of the parties; or (3) the use of the court's procedures would bring the administration of justice into disrepute.
26 As Lord Sumption JSC observed in Virgin Atlantic Airways Limited v Zodiac Seats UK Limited (formerly known as Contour Aerospace Limited) [2013] UKSC 46; [2014] AC 160 (at 180 [18]), it is only in relatively recent times that courts have endeavoured to impose some coherent scheme on this area of the law. This includes what his Lordship described as the "portmanteau term" of res judicata, which is used to describe a number of different legal principles with different juridical origins; although his Lordship noted (at 180 [17]) that "[a]s with other expressions, the label tends to distract attention from the contents of the bottle".
27 The question of in what circumstances can courts preclude the ability for relitigation runs through a variety of areas of the law. As class actions develop, and continue to increase as a mechanism by which courts quell controversies through the use of judicial power, it is necessary to give close thought to the circumstances in which a party to one representative proceeding, who has had a determination of common issues, is entitled to relitigate those issues. In my mind, it is difficult to understand why the principles of abuse of process are not sufficiently flexible to have regard to the bespoke circumstances in which a respondent in a representative proceeding, with all the ability to participate in that representative proceeding, is able to relitigate an adverse decision on issues which transcend that proceeding; that is, the common issues. The maxim interest rei publicae ut sit finis litium (it is for the common good that there should be an end to litigation) has a particular resonance when it comes to the determination of common issues in group proceedings.
28 Returning to the difficulty with adjourning temporarily the Martini proceeding, there is a risk that in the absence of an undertaking, both the applicant and group members in the Martini proceeding, and Boral, may consider themselves in a position to reagitate common issues. However, to adopt the expression of Mr Edwards, counsel for the applicant in the Parkin proceeding, such risk should be considered "vanishingly low", not only because of the potential legal impediments I have identified above, but also because it does not seem to be practicable that such an eventuality would result. From the perspective of the applicant in the Martini proceeding, this is a case involving funded litigation. It would be quite remarkable if, following an adverse determination of the common issues in the Parkin proceeding, it could be seriously said to be commercially viable for a funder to advance funds for the relitigation of those issues in another representative proceeding.
29 In relation to individual group members, the relitigation of common issues in a case such as the present would be very unlikely. Similarly, for Boral, even if, contrary to my preliminary view, there is an ability to relitigate common issues, there does not seem to me to be a realistic prospect this would occur, particularly in circumstances where any determination of the common issues could be the subject of an appeal.
30 In these circumstances, it follows that the risks of adjourning or ordering a temporary stay are relatively remote.
