Discretionary considerations
46 Despite Mahoney AP's statement in Garrard, there is no absolute right to have an ex parte order set aside; there is a discretion in the court whether to do so or not: Dormeuil Frères SA v Nicolian International (Textiles) Ltd [1988] 3 All ER 197 at 199 ("Dormeuil").
47 In Dormeuil, Browne-Wilkinson VC expressed the view that the appropriate time for the court to hear and determine an application to discharge a search order on the ground that it was obtained as a result of material non-disclosure is at the trial because, the order usually having been executed, the only consequence of the non-disclosure will be to affect the plaintiff's liability under his undertaking as to damages, and interlocutory proceedings are not the appropriate time for the court to hear evidence and determine allegations of what has happened in the past.
48 In Dart Industries v Bryar (1997) 38 IPR 389 at 419, Goldberg J, agreeing with Browne-Wilkinson VC, said that "save in exceptional cases it is not the correct procedure to apply to discharge an ex parte injunction on the grounds of lack of full disclosure at the interlocutory stage of the proceedings". Goldberg J also accepted "the tentative view expressed by Sir Nicholas Browne-Wilkinson VC in Tate Access Floors Inc v Boswell [[1991] Ch 512 at 532-3] that investigations of the circumstances in which an ex parte Anton Piller [or search] order was granted should be restricted to those cases where there has been a serious failure to make a material disclosure". His Honour declined to discharge the search order in that case. See also Liberty Financial Pty Ltd v Scott [2002] FCA 345 at [71].
49 In WEA Records Ltd, Donaldson MR said at 727:
In the instant case the Anton Piller order is spent in the sense that it has been executed. However, the defendants seek to go back to the beginning of the action saying that, regardless of whether the fruits of the order are such as to show that it was abundantly justified, the judge had insufficient material to justify his action at the ex parte stage. They therefore invite us to set the ex parte order aside and to order the return of the …seized material …
I regard this as wholly absurd. The courts are concerned with the administration of justice, not with playing a game of snakes and ladders. If it were now clear that the defendants had suffered any injustice by the making of the order…the defendants would have their remedy in the counter-undertaking as to damages. But this is a matter to be investigated by the High Court judge who is seised of the matter…
50 In Brags Electrics Pty Ltd v Gregory [2010] NSWSC 1205, Brereton J declined to set aside an Anton Piller order. At [17], he summarised the relevant principles as follows:
First, where an Anton Piller order is made ex parte (as it ordinarily will be), an applicant to set the order aside bears an onus of showing some reason why it should be set aside. However, it may be a sufficient reason to set aside the order that the grounds for such an order were not satisfied. Secondly, where such an application is made on the ground that there has been bad faith or material non-disclosure, then the court may set aside the order ab initio, but otherwise a discharge will operate in futuro only. Thus, where an application is made to set aside or discharge the order on the basis that the grounds for making such an order were not established, that will be of little utility if made after the order has been executed. At least in the absence of bad faith or non-disclosure, the remedy for a defendant where it is shown ultimately that an Anton Piller order ought not have been made, is not to have the order set aside, but pursuant to the undertaking as to damages. Thirdly, on an application to set aside an Anton Piller order, the court may take into account on the hearing of the application the "fruits of the order" - that is to say, any evidence or admission procured as a result of the order - and any further evidence adduced in the meantime.
51 In Campaign Master (UK) Ltd v Forty Two International Pty Ltd (No 4) (2010) 269 ALR 76 at [69], Yates J said (albeit not in the context of an application to set aside an ex parte application):
…even in the case of orders of a procedural nature, the principle of finality of litigation does have a role to play which, having regard to considerations of case management, is not unimportant. It is to be borne in mind that the civil practice and procedure provisions respecting this court, including its rules made under the Federal Court of Australia Act, 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 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, even where the orders are of a procedural nature.
52 In JC Techforce, Branson J identified the following two factors "telling against the exercise of the discretion" to set aside a search order, after the order had been executed:
(1) the failure of the respondents to identify any utility which would result from the setting aside of the order;
(2) the delay (of three months) which attended the making of the application.
