CONSIDERATION
6 As Black CJ and French J noted in Ruddock v Vadarlis (No 2) (2001) 115 FCR 229 at [9], the Court's power to award costs pursuant to s 43 of the Federal Court of Australia Act 1976 (Cth) is not fettered by any stated legislative presumption about the manner of its exercise. Nonetheless, it must be exercised judicially and not against a successful party except for some reasons connected with the case.
7 In Ruddock v Vadarlis (No 2) at [17], Black CJ and French J noted the relevance to the exercise of the Court's discretion to award costs of an appeal raising a novel question of general importance. Their Honours cited Perrett v Commissioner of Superannuation (1991) 29 FCR 581 at 594 where, in the context of a statutory appeal from the Administrative Appeals Tribunal, the Full Court said:
The court should consider the matter of costs, bearing in mind the result of the appeal but also taking into account the reasonableness of the applicant in bringing that appeal and the general importance of the clarification of the law for such an authority as the respondent.
8 The principal issues to be determined on this appeal concerned the proper construction of the Environment Protection and Biodiversity Conservation Act 1999 (Cth) ("the EPBC Act"). They were thus issues of critical importance to the Minister in the performance of his responsibilities as the Minister responsible for the administration of that Act.
9 That difficulty attended at least the issue concerning the proper construction of s 42 of the EPBC Act is demonstrated by the different views on this question adopted by Branson and Finn JJ, on the one hand, and Tamberlin J on the other. The reasons for judgment of the learned primary judge, which deal with the question somewhat summarily, suggest that this issue did not loom large at first instance. The evidence discloses that the difficulties attending the proper construction of certain provisions of the EPBC Act, including s 42, were probably not recognised by the Minister's departmental advisers. For these reasons, and notwithstanding the reasons for judgment of the primary judge, it was of general importance both to the Minister and to the public that the law concerning the proper construction of the provisions of the EPBC Act with which this appeal was concerned should be clarified.
10 Significance may also be seen to attach to the fact that the appellant was concerned, along with a large segment of the Australian community, to avoid harm to the Australian environment. The appellant was not seeking financial gain from the litigation; rather it appropriately sought to resolve a dispute, which had engaged the emotions of many, concerning the proper administration of the EPBC Act in the Court rather than elsewhere (see Oshlack v Richmond City Council (1998) 193 CLR 72 per Gaudron and Gummow JJ at [20] and [59] and Kirby J at [136]-[144]).
11 For the above reasons, while we do not consider it appropriate to withhold from the Minister an order for costs in his favour, we have concluded that it would be appropriate to limit the costs to be recovered by the Minister. In our view the appropriate order is that the appellant pay 70% of the Minister's party/party costs, including reserved costs, of the appeal.
12 For the following reasons we also consider it appropriate to limit the costs to be recovered by Gunns. Gunns had an obvious interest in the proceeding both at first instance and on appeal. It was its proposal to construct and operate a bleached Kraft pulp mill that was the subject of the decisions of the Minister that the appellant challenged. Gunns was for this reason a proper party to the proceedings. However, no conduct of Gunns was challenged by the appellants. Nor did Gunns have any reason to conclude that the Minister would not deploy appropriate legal resources to defend the appeal. On appeal, as at first instance, the Minister retained both senior and junior counsel to appear for him. Gunns also retained both senior and junior counsel. It was not apparent to the Court that Gunns' legal representatives saw their role as being principally to supplement, assuming it to be necessary, the written and oral submissions of the Minister. Rather, Gunns sought to participate on equal terms with the Minister in the defence of the appeal. This was illustrated by, but not limited to, Gunns substantial written submissions on the issue of whether the Minister had acted for an improper purpose.
13 Orders for costs are made to compensate a successful party. The ordinary rule that costs follow the event assumes that a successful party will have incurred costs because the unsuccessful party made it necessary for the successful party to do so (Ruddock v Vadarlis (No 2) per Black CJ and French J at [12]). Having regard to the fact that it was the Minister who was the more appropriate contradictor on this appeal, we consider that Gunns played a larger role in the appeal than was necessary. The extent to which the costs recoverable by Gunns should for this reason be limited is a matter of judgment or impression; it is not susceptible to precise calculation. In all the circumstances we have concluded that it is appropriate to limit the costs recoverable by Gunns to 40% of its party/party costs, including reserved costs, on the appeal.
