The Authorities
5 In Oshlack v Richmond River Council (1998) 193 CLR 72 ("Oshlack"), Gaudron and Gummow JJ held that a trial judge who decided not to order an unsuccessful party to pay a successful party its costs had not erred in the exercise of his discretion in taking the following matters into account:
(1) The fact that proceedings may be characterised as "public interest litigation" may be a factor which contributes to a conclusion of "special circumstances" so as to justify a departure from the ordinary rule that the unsuccessful party pays the successful party's costs. However, of itself it is not sufficient to justify a departure;
(2) The fact that the unsuccessful applicant had pursued the litigation in order to ensure compliance with the law and not for the purposes of private gain;
(3) The fact that a significant number of members of the public shared the unsuccessful applicant's concerns and in that sense there was a "public interest" in the outcome of the proceeding; and
(4) The fact that the basis of the challenge was arguable and had resolved significant issues about an Act of Parliament and its administration.
6 Their Honours referred to the concept of public interest and said (at 84):
That is a 'nebulous concept' unless given, as the primary judge did in the present case, further content of a legally normative nature. It also tends, in this litigation, to distract attention from the legal issue which is at stake.
7 A matter may be in the public interest because a substantial section of the public are affected by the subject matter of the litigation. By contrast, a matter may not be in the public interest for the purpose of determining the appropriate order as to costs simply because members of the public are interested in the result. There may be cases where the circumstances are such that public confidence in the rule of law is advanced by the hearing and determination of the important issues by a Court. There may be a significant public interest in the determination of important and difficult questions of law.
8 In Ruddock v Vadarlis & Ors (No 2) (2001) 115 FCR 229 ("Ruddock v Vadarlis (No 2)"), Black CJ and French J reviewed the general principles relating to the award of costs. Their Honours referred to a number of matters including the effect of conferring a discretion on Courts of summary jurisdiction to award costs in criminal proceedings, the awarding of costs by reference to a party's conduct in a proceeding, the award of costs on an appeal and the decision in Oshlack. In the case before them their Honours ordered that there be no order as to costs either of the appeal or the application at first instance. Their Honours said (at 242 [29]):
This is a most unusual case. It involved matters of high public importance and raised questions concerning the liberty of individuals who were unable to take action on their own behalf to determine their rights. There was substantial public and, indeed, international controversy about the Commonwealth's actions. The proceedings provided a forum in which the legal authority of the Commonwealth to act as it did with respect to the rescued people was, and was seen to be, fully considered by the Court and ultimately, albeit by majority, found to exist. The case is quite different in character from the predominantly environmental litigation in which may [sic] of the previous decisions concerning the impact of public interest considerations on costs awards have been made. Having regard to its character and circumstances the appropriate disposition is that there be no order as to the costs of the appeal or the application before North J.
9 In Save the Ridge Inc (Association No AO3329) v Commonwealth and Anor (2006) 230 ALR 411, the Full Court of this Court considered the question of the costs of an appeal in a case involving environmental legislation.
10 It is important to note that different weight may be given to the relevant considerations on an appeal from the weight given to the same considerations in a proceeding at first instance. For example, the clarification of the law and rule of law considerations, may not, depending on the circumstances, have the same weight on an appeal.
11 The Full Court decided that there was insufficient reason to depart from the ordinary rule. In the course of its reasons, the Court made the following observations. First, in the case of an appeal raising a novel question of much general importance and of some difficulty, a Court may decline to order that an unsuccessful party pay the costs of a successful party. At the same time, it was relevant in that case that the appeal raised points "which were, although not unimportant, much more limited in their application" than those raised in Ruddock v Vadarlis (No 2) (at 415 [13]). The fact that a case raised important and difficult questions did not of itself amount to special circumstances. Secondly, the fact that an appellant sought no financial gain from the litigation did not of itself justify a departure from the usual order as to costs. Thirdly, the Court said that the extended standing provisions under the EPBC Act was not a reason to more readily depart from the usual order as to costs.
12 In Blue Wedges Inc v Minister for the Environment, Heritage and the Arts and Others (2008) 165 FCR 211 ("Blue Wedges Inc"), Heerey J, sitting at first instance made no order as to costs in the case of a proceeding involving the EPBC Act. His Honour took into account the following matters: (a) the applicant represented a large number of community and environment groups and had been actively campaigning about the environment of Port Phillip Bay over many years; (b) the condition of Port Phillip Bay was a matter of high public concern and not only for the four million or so Victorians who lived around it; (c) in the case before the trial judge what was in the public interest and what the public were interested in coincided; and (d) the application raised novel questions of general importance as to the approval process under the EPBC Act.
13 In Bat Advocacy NSW Inc v Minister for Environment Protection, Heritage and the Arts and Anor (No 2) (2011) 280 ALR 91, the Full Court was invited to deal with the costs not only of the appeal, but also the costs at first instance. It declined to deal with the costs at first instance. As to the costs of the appeal, the Court said that the fact that some members of the public demonstrated some interest in the issue of the removal of the grey-headed flying foxes ("GHFF") from the Royal Botanic Gardens in Sydney was not sufficient to establish special circumstances. The Court also took into account the fact that the appeal before the Court raised factual matters which had no precedent value to future decisions under the EPBC Act or about the GHFF and the fact that, although arguable, the grounds of appeal could not be said to have strong prospects of success.
