Legal principles
6 The Court has a broad discretionary power to award costs pursuant to s 43(2) of the Federal Court of Australia Act 1976 (Cth) (Act). The discretion must be exercised judicially, not arbitrarily or capriciously, having regard to the relevant principles and the justice of the case in all the circumstances and cannot be exercised on grounds unconnected with the litigation: Summers v Repatriation Commission (No 2) [2015] FCAFC 64 (Summers) at [13]-[14] (Kenny, Murphy and Beach JJ), citing Trade Practices Commission v Nicholas Enterprises Pty Ltd (No 3) [1979] FCA 143; (1979) 28 ALR 201 at 206-207 (Fisher J); InterPharma Pty Ltd v Hospira, Inc (No 4) [2018] FCA 45 (InterPharma) at [8] (Kenny J).
7 In the ordinary course, in the absence of special circumstances justifying some other order, the general rule is that costs will be awarded to the successful party, that is, costs will follow the event: Summers at [14]; Ruddock v Vadarlis (No 2) (2001) 115 FCR 229; [2001] FCA 1865 (Ruddock) at [11] (Black CJ and French J). In at least a public interest context, however, a case that was close or difficult and where there was no obvious fault on the part of the unsuccessful party, the proposition that costs automatically follow the event may result in unfairness. However I note that this would not justify a "global modification" to the usual rule, rather it would indicate the "desirability of avoiding calcification of the discretion with rigid rules governing its exercise": Ruddock at [13] (Black CJ and French J).
8 Rule 40.04(a) the Federal Court Rules 2011 (Cth) (FCR) provides that:
If no order for costs is made on an interlocutory application or hearing, the costs of the application or hearing:
(a) if an order is made in favour of any party - follow the event; or
(b) if no order is made in favour of any party - are taken to be costs in the cause of the successful party to the proceeding.
9 Costs orders in favour of parties that have succeeded in obtaining orders on an interlocutory basis, consistently with the default positon, are commonly made in circumstances where a party has succeeded on a discrete issue, such as the determination of a separate question in advance of a final hearing, although each case will turn on its particular facts and circumstances: Taylor (liquidator), in the matter of Heading Contractors Pty Ltd (in liq) v Heading (No 2) [2021] FCA 925 at [18] (Charlesworth J).
10 In that context, the making of a costs order following the grant of an interim injunction should be further informed by the following specific principles.
11 First, there is a marked distinction between an interlocutory order that disposes of a separate question or a discrete issue in advance of a final hearing and an interim injunction that is obtained for the purpose of preserving the status quo pending a final determination of an applicant's cause of action. In the latter case, the Court has not conclusively determined any controversy between the parties, it has only made a preliminary assessment of the strength of an applicant's cause of action and had regard to the balance of convenience pending trial: Australian Securities and Investments Commission, in the matter of Whitebox Trading Pty Ltd v Whitebox Trading Pty Ltd (No 2) [2017] FCA 385 at [6] (Gleeson J).
12 Second, an order that each party's costs be costs in the cause or that an applicant's costs be costs in the cause following the determination of an application for an interlocutory injunction, has been described as the "usual order". It has been said to be "a shorthand form of giving effect to the principles that govern the court's discretion … where there are no countervailing or different circumstances to warrant the exercise of the discretion in a different manner": His Eminence Metropolitan Petar, Diocesan Bishop of the Macedonian Orthodox Church of Australia and New Zealand v The Macedonian Orthodox Community Church St Petka Incorporated & Anor (No 2) [2007] NSWCA 142 (Metropolitan Petar) at [27] (Beazley, Giles and Hodgson JJA); Boscolo v TCN Channel Nine Pty Ltd (No 2) (unreported, Supreme Court of New South Wales, Young J, 28 April 1994) at [20].
13 The following rationale for a costs in the cause order was advanced by the New South Wales Court of Appeal in Metropolitan Petar at [21]:
The rationale for making an order that costs be costs in the cause is that, at the stage of granting an interlocutory injunction, the court is not in a position to adjudicate on the ultimate outcome of the proceedings. Rather, provided there is a reasonable case to be tried, the Court's focus in deciding whether to grant the application for interlocutory relief is on other considerations and, in particular, on determining whether, on the balance of convenience, an injunction ought to be granted. Accordingly, if a plaintiff who applies for an interlocutory injunction is not ultimately successful in the proceedings, that plaintiff should not receive the costs of the application for an injunction which, when the matter is considered in overview cannot be sustained. However, as already explained, each case must depend upon its own facts.
14 Third, the usual but not invariable practice is that, in the absence of any specific disentitling conduct, the appropriate costs order in circumstances in which an applicant has been successful in obtaining an interlocutory injunction is that costs be the applicant's costs in the cause rather than each party's costs in the cause: Metropolitan Petar at [32]; Devereaux Holdings Pty Limited v Pelsart Resources NL (No 2) (unreported, Supreme Court of New South Wales, Young J, 24 July 1985) (Devereaux) at 2; Ausino International Pty Ltd v Apex Sports [2006] NSWSC 1119 at [55]-[56] (Campbell J); Novartis AG v Hospira Pty Limited (No 2) [2012] FCA 1113 at [10] (Yates J); Dincel Construction System Pty Limited v AFS Systems Pty Ltd [2017] FCA 262 (Nicholas J) subsequent to the delivery of reasons as noted in Dincel Construction System Pty Limited v AFS Systems Pty Ltd (No 3) [2017] FCA 919 at [3] (Nicholas J); cf InterPharma at [11]-[12] (Kenny J); Sigma Pharmaceuticals (Australia) Pty Ltd (ACN 004 118 594) v Wyeth (2009) 81 IPR 339; [2009] FCA 595 (Sundberg J); James v Commonwealth Bank of Australia (No 2) [2015] FCA 599 at [20] (Katzmann J) (but the order in that case for costs to be each party's costs in the cause was made because of late amendments by the successful applicant where an earlier order was made that costs follow the event).
15 The prevailing practice with respect to the making of costs orders following the grant of interlocutory injunctions was, with respect, usefully summarised by Young J in Devereaux at 2, at least as at the date of his Honour's judgment:
My researches as to the local practice as to costs when an interlocutory injunction is granted but then the proceedings are dismissed on final hearing, have not led to any definitive rules being uncovered, but the following seems to be what commonly happens in such cases:
(a) If the material before the Judge on the interlocutory hearing discloses that there is an arguable or prima facie case and it is more or less conceded in argument that such is the case so that an interlocutory injunction is granted, then costs of the interlocutory injunction are costs in the cause, though sometimes they may be made plaintiff's costs in the cause;
(b) If in the situation set out in (a), the defendant does not concede the inevitability of an interlocutory injunction being granted, then the proper order is that the plaintiff's costs be his costs in the cause, or even that the defendant pay the plaintiff's costs in any event;
(c) If the main matter argued on the interlocutory application is a question of law which is fully argued, then very often the appropriate order will be that the winner of the argument gets an order for his costs of the interlocutory application in any event, though the order may be that the costs are those of the successful party in the cause;
(d) If the motion is treated by the parties as merely being a minor step in the final proceedings, then the appropriate order is that each party's costs being their costs in the cause;
(e) If there is an interlocutory motion which is properly brought, and both parties are partially successful, both parties' costs should be costs in the cause;
(f) If an interlocutory motion for injunction is properly brought and fails, then either both parties' costs will be costs in the cause, or alternatively the proper order will be that the defendant's costs be costs in the cause.
16 Fourth, it may be preferable to make a costs order at the conclusion of a hearing of an application for an interlocutory injunction, rather than an order reserving the question of costs, when regard is had to the complexity of the issues and arguments raised and the volume of substantive evidence adduced: see InterPharma at [11] (Kenny J); cf Reckitt Benckiser Healthcare (UK) Ltd v GlaxoSmithKline Australia Pty Ltd (No 2) (2013) 103 IPR 472; [2013] FCA 736 (Rares J) and Eli Lilly and Company v Generic Health Pty Ltd [2013] FCA 1254 at [82] (Nicholas J).
