(b) Autodesk Inc v Dyason (No 2) [1993] HCA 6; (1993) 176 CLR 300 (at 302 - 303), where Mason CJ (who dissented as to the outcome) referred to the passage set out above from Wentworth , and continued:
"But these statements do not exclude the exercise of jurisdiction to reopen a judgment which has apparently miscarried for other reasons, at least when the orders pronounced have not been perfected by the taking out of formal orders . So much was acknowledged by Brennan, Dawson, Toohey and Gaudron JJ in Smith v New South Wales Bar Association [1992] HCA 36; (1992) 176 CLR 256 at 264-266 when their Honours said:
'if reasons for judgment have been given, the power is only exercised if there is some matter calling for review.'
…
However, it must be emphasised that the jurisdiction is not to be exercised for the purpose of reagitating arguments already considered by the Court; nor is it to be exercised simply because the party seeking a rehearing has failed to present the argument in all its aspects or as well as it might have been put. What must emerge, in order to enliven the exercise of the jurisdiction, is that the Court has apparently proceeded according to some misapprehension of the facts or the relevant law and that this misapprehension cannot be attributed solely to the neglect or default of the party seeking the rehearing . The purpose of the jurisdiction is not to provide a backdoor method by which unsuccessful litigants can seek to reargue their cases." (emphasis added)
33 The "general rule" as to costs is that, subject to UCPR 42, they follow the event unless it appears to the Court that some other order should be made in whole or in part: UCPR 42.1. The appeal was determined, and Order 4, (as well as the order as to the costs of the appeal) was made, on that basis. The effect of Nationwide's notice of motion is that it seeks a rehearing on the issue of the costs of the liability hearing. The principles of finality to which we have referred clearly bear on whether we should accede to that application.
34 We turn then to the question whether UCPR 36.16(3) gives the Court power to set aside a costs order which has been entered. There is no binding decision of this Court supporting the proposition that that rule provides the power for which Nationwide contends. It relies on Hancock (at [10]) where the Court (Ipp, McColl and Basten JJA) tentatively opined:
"10 The precise scope of this provision [UCPR 36.16(3)] is unclear. Read literally, it might be thought to operate only in respect of orders which were not sought by any party. That reading seems implausible. Given its context, it is more likely that the distinction intended to be drawn is between substantive relief, to which the power does not extend, and ancillary or consequential relief, to which it does extend. On that understanding, a costs order would clearly fall within the latter category. Such a distinction would make practical sense because appropriate orders as to costs frequently depend upon the existence of offers of compromise which are properly not known to the Court until after substantive relief has been determined." (emphasis added)
35 However, on the facts of Hancock the Court did not have to determine whether UCPR 36.16(3) conferred the power for which Nationwide contends. Nor have subsequent decisions of this Court resolved that position. Rather they have created an unresolved tension. In Roads and Traffic Authority of NSW v Refrigerated Roadways Pty Ltd (No 2) [2009] NSWCA 336 (at [8]), Campbell JA (McColl JA and Sackville AJA agreeing), described Hancock (at [9] - [12]) as "contemplat[ing] the possibility that a costs order could be varied notwithstanding that no notice of motion was filed within 14 days after the order was entered in the Court's computer system, if there had been an oral application to vary it within the 14 day period, and if either UCPR 36.16(3) or section 14 Civil Procedure Act 2005 were invoked." His Honour suggested, without the benefit of argument, that a costs order made in response to an application for such an order in the notice of appeal, was one that "determines any claim for relief", and accordingly that UCPR 36.16(3) was not applicable.
36 Campbell JA's view accords with Roads and Traffic Authority of NSW v Palmer (No 2) [2005] NSWCA 140 where the Court considered Pt 40 r 9(4) of the Supreme Court Rules 1970 (NSW), which was in substantially the same terms as UCPR 36.16(3). The Court (per Giles JA, Spigelman CJ and Handley JA agreeing) (at [20] - [21]) held that costs orders determined claims for relief, the relief claimed being orders disposing of the costs of the trial and of the appeals, and hence did not fall within the limited exception that rule afforded. Palmer has not been referred to in any of the decisions of this Court or the first instance judges referred to below in which the scope of the UCPR 36.16(3) power has been considered.
37 Nationwide referred to first instance decisions which it contended supported the proposition that a claim for costs was not a "claim for relief" within the meaning of UCPR 36.16(3): Saul v Lin [2007] NSWSC 782, Vaughan v Hoskovich (No 2) [2010] NSWSC 835, Short v Crawley and Sundararajah.
38 It might be noted that with the exception of a bald statement in Saul v Lin (at [13]) none of those cases (nor any decision of this Court to which Nationwide referred) have considered the question whether even if, assuming without deciding, a claim for costs was not a "claim for relief", it nevertheless "determines any question (whether of fact or law or both) arising on any claim for relief": UCPR 36.16(3). There is much to be said for the view that UCPR 36.16 is intended to apply to all claims for substantive relief and orders ancillary thereto, and that the exception UCPR 36.16(3) carves out reflects the court's power to set aside, vary or discharge an interlocutory order: see Brimaud v Honeysett Instant Print Pty Ltd (1988) 217 ALR 44 (at 46) per McLelland J (as his Honour then was); Deputy Commissioner of Taxation v Meredith (No 2) (at [14]).
39 Giles JA's conclusion in Palmer formed part of the ratio of that decision and is binding on this Court in its consideration of UCPR 36.16(3) which, as we have said, is in substantially the same terms as the rule his Honour was considering. However Palmer was, and this case is being, decided on the papers without the benefit of oral argument. In those circumstances we would not wish to express a concluded view about the meaning of the rule. In any event, it is not necessary in our view for this Court to determine whether it has the power for which Nationwide contends. This is because there are a number of reasons why, even if it had that power, Nationwide's application should not be granted.
