Applicable Principles
12 By s 25(2B)(ab) of the FCA Act, a single judge or a Full Court may:
(ab) make an interlocutory order pending, or after, the determination of an appeal to the Court; or
It is further provided in s 25(2B)(bc) that a single judge or a Full Court may:
(bc) vary or set aside an order under paragraph (ab), (ba) or (bb); or
There is clearly a statutory foundation for the interlocutory orders made by White J and there is also a statutory power (s 25(2B)(bc)) to set aside that order. The question is whether the power should be exercised.
13 It is to be noted that the power to set aside an order would ordinarily be exercised by the Court which made the order: see, for example, Dunstan v Human Rights and Equal Opportunity Commission [2007] FCA 1326 per Gyles J (at [4]). However, given the way in which the application arose, in my opinion it is appropriate that I determine the application.
14 A discretion to vary or set aside an order after it is entered is also conferred by r 39.05 of the Federal Court Rules 2011 (Cth). Unlike r 39.05, which confines the discretion to vary or set aside orders to the discrete circumstances enumerated, the power under s 25(2B)(bc) is not similarly confined. I note that the application of r 39.05 of the Rules in the context of the Court's exercise of appellate jurisdiction is a question which has not been directly addressed: Finch v Heat Group Pty Ltd (No 3) [2016] FCA 102 per Murphy J (at [22]); and Mulholland v Australian Electoral Commission (No 2) [2014] FCA 917 per Mortimer J (at [23]); cf AAI15 v Minister for Immigration and Border Protection [2018] FCA 1110 per Tracey J (at [28]). I have not heard argument on the issue, but I will assume, without deciding, that the principles established by this Court as relevant to an assessment of the exercise of the discretion conferred by r 39.05 of the Rules are apposite in the context of an application brought pursuant to s 25(2B)(bc) of the FCA Act.
15 In the r 39.05 context, this Court has identified the following principles as relevant:
(a) the scope of the power to vary or set aside an order or judgment after entry is more circumscribed than that provided for in relation to the pre-entry situation. It should be exercised with caution and in exceptional circumstances, mindful of the overarching principle of the finality of litigation: Australian Securities and Investments Commission v ActiveSuper Pty Ltd (No 4) [2013] FCA 318 per Gordon J (at [6] and the authorities therein cited);
(b) the discretion to vary an order is not confined, but must be exercised judicially and the Court must have regard to all the evidence and arguments before it at the time of the application: Campaign Master (UK) Limited v Forty Two International Pty Ltd (No 4) (2010) 269 ALR 76 per Yates J (at [68]);
(c) the power conferred must be exercised in a way that best promotes the overarching purpose identified in s 37M of the FCA Act, of facilitating the just resolution of disputes according to law as quickly, inexpensively and efficiently as possible; and
(d) the Court must also consider the rights and interests of third parties. Orders may be varied or set aside where the party in whose favour the order was made consents, provided that doing so will not detrimentally affect the rights or interests of third parties: Australian Securities and Investments Commission v Yandal Gold [2003] FCA 77 per Merkel J (at [23]); Perre v Apand [2004] FCA 1220 per Selway J (at [10]-[11]).
16 It would be wrong to regard these as discrete considerations. The emphasis placed by this Court in cases considering the setting aside or variation of orders on the need for there to be "exceptional circumstances" reflects the importance placed, including on appeal, on the finality of litigation. The principle of finality of litigation has an important role to play which, having regard to considerations of case management, is not unimportant even in cases concerning orders of a procedural nature. It is to be borne in mind that the FCA Act and Rules must be interpreted and applied, and every power conferred by them must be exercised or carried out, in the way that best promotes the overarching purpose identified in s 37M of the FCA Act of facilitating the just resolution of disputes according to law as quickly, inexpensively and efficiently as possible. That overarching purpose will not be achieved, but will be subverted, by a too-ready resort to, or incautious application of, the power to vary or set aside orders that have been made and entered.
17 In this context it is appropriate to have regard to what the High Court (Gummow ACJ, Hayne, Heydon, Crennan and Kiefel JJ) said in Burrell v The Queen (2008) 238 CLR 218 (at [18]-[21]). Their Honours held that the end of a court's powers to consider and determine a controversy cannot depend on whether one party asserts that the court has made some error in the conclusion that it reached. If that were the criterion, they said, there would never be an end to some disputes. Their Honours also held that the court's own belief that it had made an error (taken alone) did not allow it to reopen a decision. Their Honours held that a formal recording of the order of a superior court, such as this court, is 'the point at which the court's power to reconsider the matter is at an end'.
18 It is with these principles borne in mind that I turn to the parties' submissions.
