D SUFFICIENT DOUBT?
17 To assess whether the first Décor limb is made out, it is sufficient to consider the proposed appeal at a reasonably impressionistic level and assess whether the proposed appeal is sufficiently arguable. Obviously enough, it will seldom be in the interests of the administration of justice (or consistent with promoting the overarching purpose in accordance with s 37M of the Act) to grant leave where an appeal has little prospect of success: MZABP v Minister for Immigration and Border Protection [2015] FCA 1391; (2015) 242 FCR 585 at 597-598 [62]-[63] (Mortimer J).
18 The issue that arose below was one of case management peculiar to the context of competing class actions. As the Full Court observed in Perera v GetSwift Ltd [2018] FCAFC 202; (2018) 263 FCR 92 at 125-126 [146]-[147]:
First, Pt IVA contemplates that there may be more than one proceeding against the same respondent in respect of the same subject matter and the same cause(s) of action (Bellamy's at [34]). A claimant has a choice whether to bring representative proceedings on behalf of "some or all" persons. If that choice is not made, one or more claimants may bring separate individual proceedings against the one respondent in respect of the same claims or may aggregate their claims into another representative proceeding. Thus the Part contemplates the possibility of a multiplicity of proceedings.
Moreover, even if representative proceedings are brought, one or more group members may opt out and bring their own individual proceedings, resulting in multiple proceedings against the same respondent. Indeed, such group members who have opted out may bring their own separate representative proceedings. Nothing in Part IVA precludes such an option. And to do so would neither be invalid nor an abuse of process. In other words, the structure of Part IVA permits of multiple proceedings including multiple representative proceedings.
19 Part IVA recognises the possibility of multiple class action proceedings and does not mandate that the respondent will only face one proceeding or one set of adverse legal costs. Having said this, the undesirability of multiple class actions for the one alleged wrong and the desirability of avoiding duplication of costs in the interests of the respondent and also group members is obvious.
20 As has been repeatedly stressed, the remedial expedient to be adopted when the Court is faced with competing class actions calls for discretionary judgments informed by all the circumstances of the case. Unsurprisingly, such judgments are ones upon which minds can (and do) legitimately differ. What is evident from the recent decisions of the Full Court in GetSwift and Klemweb is that not only do docket judges have considerable latitude to fashion a solution to deal with multiplicity of class actions, but also that the issue of potential duplication of costs is a relevant discretionary factor in fastening upon the appropriate case management solution.
21 One of the potential consequences of a case management decision which allows more than one class action to proceed is at least some duplication for costs, and mitigating any unfairness that might flow to a respondent or group members is part of the case management role of the docket judge implementing the decision which permitted more than one case to proceed. This is precisely what occurred in the circumstances of this case and the applications for leave to appeal must be considered in this context.
22 Each of the five proposed grounds of appeal interrelate and can be dealt with shortly.
23 The first proposed ground is that the primary judge erred by applying incorrect legal principles in determining whether the proposed costs limitation order should be made. In summary, the contention is that: (a) a "general principle" or "rule" exists to the effect that in the absence of an identified exception (being an actual or potential conflict of interest between multiple applicants or any trade rivalry justifying separate representation), where separate representation is allowed, multiple applicants cannot choose to be separately represented at the respondent's expense; and (b) the fact that both class actions were allowed to proceed was not a reason to decline to apply the general principle, but rather it enlivened its operation.
24 This ground does not have substantive merit. As counsel for BAL accepted, the so-called general principle as to double representation said to have been developed in the different context of ordinary inter partes litigation did not mandate the proper exercise of the primary judge's discretion. The Court's discretion as to costs issues is often described as unfettered although, given the requirement imposed by s 37M(3) of the Act to exercise any practice and procedure discretion in a way that promotes the overarching purpose, this may no longer be strictly accurate in this Court: see LFDB v SM (No 2) [2017] FCAFC 207 at [7] (Besanko, Jagot and Lee JJ). What is evident, however, is that given the broad discretion as to costs generally, the existence of two class actions did not require his Honour to deal with the issue in the way BAL sought it to be dealt with. The primary judge was correct to proceed on the basis that there is no rule which invariably dictates the approach required to be adopted to the costs awarded when more than one class action is brought in relation to the same alleged civil wrong, notwithstanding any general notion that ordinarily multiple applicants cannot choose to be separately represented at the respondent's expense without good reason.
25 In reaching this conclusion, the primary judge, with respect correctly, understood that there was some risk of duplication consequent on his Honour's decision to allow two proceedings to go forward but, as his Honour noted, he had a range of case management tools to prevent duplicative costs of substance being incurred and, to the extent that such prophylactic steps were insufficient, any prejudice (to either BAL or group members) could be addressed later.
26 Much emphasis was placed in oral submissions by counsel for BAL on the very recent decision of the High Court in Northern Territory v Sangare [2019] HCA 25 in which Kiefel CJ, Bell, Gageler, Keane and Nettle JJ explained at [24] that it "is well established that the power to award costs is a discretionary power, but that it is a power that must be exercised judicially, by reference only to considerations relevant to its exercise and upon facts connected with or leading up to the litigation" and, notwithstanding the width of the discretion, the "formulation of principles to guide the exercise of the discretion avoids arbitrariness and serves the need for consistency". In that case, the important guiding principle was that the successful party is generally entitled to its costs and there was no suggestion of any conduct on the part of the successful party that could have justified refusing the successful party an order for its costs.
27 No comparable error is evident here. We do not consider the primary judge did anything other than exercise his discretion by reference only to considerations relevant to its exercise and upon facts connected with the litigation with which his Honour was dealing; indeed we would respectfully agree with the pragmatic approach adopted by his Honour. In the context of the present case, the concern regarding duplicative costs was better dealt with by case management directions aimed at reducing duplicative or excessive costs and by permitting the issue to be addressed later to the extent necessary. It is certainly preferable to making an order capping the quantum of potentially recoverable costs the applicants could spend vindicating the claims while BAL would have no equivalent fetter on the sum it could spend in the defence of those claims. The asymmetry and unfairness of a one-sided order of that nature is manifest (although we note that a "cost capping" order in such terms is no longer sought in the proposed appeals).
28 The second proposed ground is that the primary judge erred in misstating and misapplying the legal principles "under what [his Honour] described as the 'English approach'" (which the primary judge characterised as only providing for such of the costs of the applicants to be disallowed as were unreasonably duplicated). It is somewhat difficult to understand what this second proposed ground adds. Although the primary judge considered there was some difference between the relevant Australian and English authorities, BAL submits that in circumstances (such as those found by the primary judge) where there is no conflict or potential conflict between the multiple parties and their relationship does not otherwise justify joint representation, an application of the English principles will produce the same result as under Australian law. Whether there is some difference between the position here and in the United Kingdom is not to the point: the issue is whether recognisable error is disclosed in the exercise of his Honour's discretion not to make the costs capping order now. For reasons explained above, there was no such error.
29 The third, fourth and fifth proposed grounds also add little.
30 The third proposed ground posits that because the primary judge applied the wrong legal test, his focus was on whether there had been (or would be) unnecessary or unreasonable duplication of work and costs by the applicants. Similarly, the fourth proposed ground is that because the wrong legal test was applied, the primary judge failed to take account of a relevant consideration, which, in effect, was said to be the authorised exceptions to the so-called general principle (the absence of any conflict or trade rivalry) were not present. Finally, the fifth proposed ground (the alleged error in finding there was no compelling reason for the proposed costs limitation order being made prospectively) is also said to be a result of the primary judge being diverted from the correct test. As set out above, these grounds cannot succeed once it is appreciated that it was open to his Honour, in the exercise of his discretion, to reject cost capping and making orders which would apply on a taxation that may never take place. It was open to the primary judge to address any duplication of costs occasioned by the decision to allow two class actions to be addressed as his Honour did.
