The primary costs order sought by the respondents
6 The primary costs order sought on behalf of the respondents was based upon the following propositions:
(1) the majority of the hearing time, the evidence and the written submissions related to the applicants' application for an anti-suit injunction, while a significantly less amount of hearing time, evidence and written submissions related to the respondents' interlocutory application;
(2) the question of whether this court was a "clearly inappropriate forum" was the main issue in respect of the respondents' interlocutory application, albeit also an issue that needed to be determined in deciding the applicants' interlocutory application. Upon determining that question, no significant additional time was required to decide the respondents' interlocutory application, such that deciding the clearly inappropriate forum question for the anti-suit injunction was also dispositive of the respondents' interlocutory application;
(3) in relation to the written submissions:
(a) the applicants' submissions dated 13 April 2017 regarding the anti-suit injunction and service on the second respondent were 25 paragraphs in length, of which only three (paragraphs 1, 24 and 25) related to the respondents' interlocutory application, with all other paragraphs dealing with the applicants' anti-suit injunction;
(b) the respondents' outline of submissions in respect of the anti-suit injunction and the application under r 13.01 of the Federal Court Rules 2011 (Cth) was 15 pages in length with various paragraphs and sub-paragraphs, of which 11 paragraphs and two separate subparagraphs dealt with the issue of clearly inappropriate forum in respect of both interlocutory applications, while the rest of the document dealt with the anti-suit injunction;
(c) the respondents outline of reply to the applicants' submissions dated 20 April 2017 was 9 pages in length, but only paragraphs 3(b) and 5(a) dealt with the issue of clearly inappropriate forum in respect of both interlocutory applications, while the remainder dealt with the issue of whether significant procedural advantages could be obtained in the United States proceedings that could not be obtained in the Australian proceedings, as well as some factual issues; and
(d) the applicants' submissions in reply dated 20 April 2017 were 13 paragraphs in length (plus an attached copy of the reasons for judgment of the Superior Court of California of 25 January 2017), with only three of those paragraphs relating to the question of clearly inappropriate forum in respect of both interlocutory applications and the balance dealing solely with the applicants' anti-suit injunction;
(4) the applicants' extensive and voluminous evidence upon which it relied at the hearing was originally served in relation to the anti-suit injunction application, whereas only a small part of the respondents' evidence related specifically to the respondents' interlocutory application - the applicants therefore effectively forced the respondents to deal with and respond to their voluminous and extensive evidence in respect of the anti-suit injunction;
(5) a trial judge has the benefit of wide discretionary powers as to costs and may separate a discernible issue at trial in respect of a costs order, with apportionment being a matter of impression and evaluation, which is a question of discretion and not mathematical precision, citing Bostick Australia Pty Ltd v Liddiard (No 2) [2009] NSWCA 304 at [38]:
The principles governing the making of an order as to costs so as to reflect the time taken in dealing with a particular issue in which the successful party in the proceedings or on the appeal did not succeed were reviewed by this Court in Elite Protective Personnel Pty Ltd & Anor v Salmon (No 2) [2007] NSWCA 373. Those principles may be summarised as follows:
• Where there are multiple issues in a case the Court generally does not attempt to differentiate between the issues on which a party was successful and those on which it failed. Unless a particular issue or group of issues is clearly dominant or separable it will ordinarily be appropriate to award the costs of the proceedings to the successful party without attempting to differentiate between those particular issues on which it was successful and those on which it failed: Waters v P C Henderson (Aust) Pty Ltd (Court of Appeal, 6 July 1994, unreported).
• In relation to trials it has been said that it may be appropriate to deprive a successful party of costs or a portion of the costs if the matters upon which that party was unsuccessful took up a significant part of the trial, either by way of evidence or argument: Sabah Yazgi v Permanent Custodians Limited (No 2) [2007] NSWCA 306 at [24]. A similar approach is adopted on appeal.
• If the appellant loses on a separate issue argued on the appeal which has increased the time taken in hearing the appeal, then a special order for costs may be appropriate which deprives the appellant of the costs of that issue: Sydney City Council v Geftlick & Ors (No 2) [2006] NSWCA 374 at [27].
• Whether an order contrary to the general rule that costs follow the event should be made depends on the circumstances of the case viewed against the wide discretionary powers of the court, which powers should be liberally construed: State of New South Wales v Stanley [2007] NSWCA 330 at [18] per Hislop J (with whom Beazley and Tobias JJA agreed).
• A separable issue can relate to "any disputed question of fact or law" before a court on which a party fails, notwithstanding that they are otherwise successful in terms of the ultimate outcome of the matter: James v Surf Road Nominees Pty Ltd (No 2) [2005] NSWCA 296 at [34].
• Where there is a mixed outcome in proceedings, the question of apportionment is very much a matter of discretion and mathematical precision is illusory. The exercise of the discretion depends upon matters of impression and evaluation: James v Surf Road Nominees Pty Ltd (No 2), citing Dodds Family Investments Pty Ltd v Lane Industries Pty Ltd (1993) 26 IPR 261 at 272.
These principles were applied in City of Canada Bay Council v Bonaccorso Pty Ltd (No 3) [2008] NSWCA 57 at [22] and most recently in Turkmani v Visvalingham (No 2) [2009] NSWCA 279.
7 As may be seen from the above passages in Bostick, where there are multiple issues in a proceeding a court will ordinarily not attempt to differentiate between the issues on which a party was successful and those on which it failed. Departure from this general position, however, may be appropriate where the particular issues in respect of which costs are sought were "clearly dominant" or "separable" from the balance. This is the critical gateway by which the respondents assert that apportionment of costs is appropriate in the present case.
8 Centrally, the respondents contended that the issue of the application for an anti-suit injunction and the issue of the application for a striking out of these proceedings, which were both heard together on 26 April 2017, could be "separable" in the Bostik sense for the purposes of apportionment of costs. It was submitted that the respondents had been successful in defeating the former application, and the applicants in defeating the latter. In those circumstances, the basis for a costs order in the respondents' favour was that there was a substantial difference in the time taken, evidence and submissions for each of the applications. In particular, it was submitted that the largest part of the case went to the question arising under the applicants' unsuccessful application for an anti-suit injunction, namely, whether the proceedings in this Court offered complete relief to the respondents, in that no advantage by way of procedure or potential relief could be obtained by the respondents in maintaining the United States proceedings. Most of the evidence adduced by Mr Herold was in relation to this application. The dominance of this issue in the written submissions was again emphasised.
9 In response, senior counsel for the applicants submitted that the test restated in Bostick of a dominant or separable issue was not able to be met in this case because the issues overlapped to such an extent that it was necessary and appropriate to address the common issues once and once only, without identifying under which rubric or which interlocutory application they were being addressed. It was submitted that a great deal of the Court's time was taken with consideration of the question of appropriate forum, which was common to both applications. Each party had to meet a burden of showing oppressiveness of the litigation and appropriateness or inappropriateness of the forum, which was sensibly addressed as an issue common to both applications. It was appropriate for the respondents to bring an interlocutory application so that the whole question of appropriate forum could be determined at the one time, which is what happened.
10 It was submitted on behalf of the applicants in the alternative that even if the only interlocutory application that had been brought was for an anti-suit injunction, and that had still failed, it would have been appropriate to order that costs be costs in the cause because it is unknown what the fate of the arguments advanced will be at the full hearing.
11 In reply, counsel for the respondents asserted that costs in the cause would not have been appropriate if only the anti-suit injunction application had been made and failed. The burden of the reply submission was that, if only the anti-suit injunction had been heard and determined, with the same outcome, the result as to costs would and should have resulted in a costs order in the respondents' favour.
