CONSIDERATION
17 As the Minister does not seek his costs, the question in issue is whether the Minister has engaged in disentitling conduct sufficient to justify a costs order against him at first instance.
18 While the Minister is correct in his submission that the relevant conduct does not strictly fall within the categories of disentitling conduct described by McHugh J in Oshlack, they should not be read as being closed or exhaustive. There is however a question as to whether, and if so, to what extent, any disentitling conduct must be connected to, or the cause of, any delay or added costs in the proceeding.
19 In Arian v Nguyen, Ipp AJA (with whom Foster AJA agreed at [1]) considered the question as follows (at [38]):
It is rare for a successful party who is guilty of misconduct in the litigation to be ordered to pay the unsuccessful opponent's costs where the misconduct does not lengthen the proceedings unnecessarily, cause unnecessary issues to be canvassed or otherwise cause the costs of the litigation to be increased. Indeed, the court's entitlement to depart from the usual order that costs follow the event has sometimes been said, in effect, to be subject to the qualification that the misconduct in question occasioned unnecessary litigation and expense (see Huxley v West London Extension Railway Company (1899) 14 App Cas 26 at 32-33 per Lord Halsbury LC; Ritter v Godfrey [1920] 2 KB 47 per Atkin LJ at 60). In other cases, however, this qualification has not been mentioned: see for example Donald Campbell & Co v Pollak [1927] AC 732 at 811-812; Thorne v Doug Wade Consultants Pty Ltd [1985] VR 433 at 500; Jamal v Secretary, Department of Health (1988) 14 NSWLR 252 at 271-272; Re Elgindata Limited (No 2) (supra). On balance, it seems to me that while delay and increased expense brought about by improper conduct in the course of the litigation are highly relevant factors in the discretion to depart from the usual order as to costs, they are not essential to the exercise of that discretion. It would, in any event, be very unusual for misconduct of that kind not to cause unnecessary delay and expense.
(Emphasis in the original).
20 Similarly, in Grass v Minister, the Full Court observed (at [3]):
Although there cannot be an absolute rule about this, it is unlikely that such an order would be made unless the disentitling conduct could in some way be seen to have caused the existence of the litigation or to have prolonged its continuance. …
In that case, the relevant Commonwealth department had deceived the appellant by informing her that she could not be listed for a citizenship ceremony due to a long list, when in fact she was being investigated by the department: Grass v Minister (at [7]).
21 The Full Court in Grass v Minister went onto make the following findings (at [9]-[10]):
9 By the time the proceeding was commenced in this Court to quash that decision the full nature of the Department's deception was known. Whilst one may readily accept that the Department's deception is a sine qua non of the litigation, we do not accept that it is, relevantly, its cause. Mrs Grass did not commence the proceeding before Buchanan J because she was suffering under a misconception which had been induced by the Department. By that time the deception had run its course. The reason the proceeding was commenced was because she wished to contest the conclusions of the learned Federal Magistrate that s 26 of the Australian Citizenship Act 2007 (Cth) did not condition the cancellation power in s 25 and that the setting aside should only be prospective.
10 In those circumstances, we do not accept that the proceedings in this Court have been either engendered as a result of the misconduct or prolonged by it. This means that the nominated disentitling conduct has not had a prolongation effect. Assuming, without deciding, that it remains possible to make the order in those circumstances, we would not do so in any event. Although the events which originally engendered the litigation do not reflect well on the Department, the fact is that its position in this Court has been fully vindicated, without any criticism of the manner in which the litigation in this Court was conducted.
(Emphasis added.)
22 In this case, the relevant conduct on the part of the Minister, through his Department, occurred well in advance of the proceedings before the primary judge which were concerned with the validity of the Tribunal's decision. The respondent's successful challenge of his continued detention by the Minister was finally determined by Wigney J, with no application for leave to appeal his Honour's decision being made. While it can of course be accepted that the relevant conduct forced the respondent to make his application for habeas corpus, the respondent received a costs order in his favour on that application as the successful party.
23 Importantly as well, the judicial review proceedings before the primary judge were brought by the Minister to challenge the validity of the Tribunal's decision. This distinguishes the present case from instances where the instigation of proceedings is in effect caused by the conduct of the ultimately successful defendant: TAI-AO Aluminium (Australia) Pty Ltd v Cordukes [2004] FCA 1488; (2004) 51 ACSR 465 per Finkelstein J (at [10]-[11]); Verna Trading Pty Ltd v New India Assurance Co Ltd [1991] 1 VR 129, where the reversal of the ordinary rule was confined to the period prior to the defendant's true defence being revealed; and Nicholas Enterprises where Fisher J (at 221-222) only ordered the unsuccessful plaintiff to pay one third of the successful defendant's costs in circumstances where an employee of the defendant made untruthful statements prior to the proceedings which rendered the plaintiff's action reasonable.
24 Without in any way qualifying our findings as to the seriousness of the Minister's conduct (through his Department) as expressed in our previous judgment, it cannot be said that the conduct had the effect of prolonging or adding to the cost of the proceedings at first instance. While the present case is somewhat unusual in that the respondent's success at first instance, and the substance of the appeal to this Full Court concerned issues that were not advanced by either party at first instance, it can be reasonably assumed that had the primary judge not made the Unlawfulness Findings, the Minister would have succeeded at first instance on the identification of jurisdictional error in the Tribunal's decision. He would then presumably have received his costs as the successful party. As events unfolded, the appeal has primarily focussed on quite different issues.
25 In our assessment, these matters support the position advanced by the Minister that there be no order as to costs.
