RELEVANT PRINCIPLES
10 In Oshlack v Richmond River Council (1998) 193 CLR 72 the appellant had sought a declaration that a development consent order the council had granted was void and of no effect. Notwithstanding his failure to obtain such an order, the appellant was not ordered to pay the costs of the respondent. The New South Wales Court of Appeal reversed that order but the High Court, by majority, in turn allowed the appeal from the decision of the Court of Appeal. In the joint judgment of Gaudron and Gummow JJ (at [49]), their Honours said:
[49] The primary judge reasoned from a starting point which favoured costs orders against the appellant as the unsuccessful party. However, he correctly drew a distinction earlier expressed as follows by Menzies J, with the concurrence of Kitto, Taylor and Windeyer JJ:
"Prohibitions and restrictions such as those under consideration are directed towards public health and comfort and the orderly arrangement of municipal areas and are imposed, not for the benefit of particular individuals, but for the benefit of the public or at least a section of the public, viz those living in the municipal area."
Having characterised the nature of the litigation as concerned with public rather than private rights, Stein J stated that "something more" than the categorisation of proceedings as public interest litigation was needed before a successful defendant should be denied costs. Stein J then isolated the factors identified in pars (iii), (iv) and (v) of the summary given earlier in these reasons as sufficient special circumstances. In proceeding to exercise in this fashion the discretion conferred by s 69, Stein J did not take into account considerations which can be said to have been definitely extraneous to any objects the legislature could have had in view in enacting s 69 and in relation to the operation of s 69 upon proceedings instituted under s 123 of the EPA Act. The contrary is the case. (footnotes omitted)
Earlier in the judgment (at [20]) there was reference to the factors mentioned by their Honours. Those factors were:
…
(iii) The appellant's pursuit of the litigation was motivated by his desire to ensure obedience to environmental law and to preserve the habitat of the endangered koala on and around the site; he had nothing to gain from the litigation "other than the worthy motive of seeking to uphold environmental law and the preservation of endangered fauna".
(iv) In the present case, "a significant number of members of the public" shared the stance of the appellant as to the development to take place on the site, the preservation of the natural features and flora of the site, and the impact on endangered fauna, especially the koala. In that sense there was a "public interest" in the outcome of the litigation.
(v) The basis of the challenge was arguable and had raised and resolved "significant issues" as to the interpretation and future administration of statutory provisions relating to the protection of endangered fauna and relating to the ambit and future administration of the subject development consent; these issues had "implications" for the Council, the developer and the public. (footnotes omitted)
11 Subsequently, in Ruddock v Vadarlis (No 2) (2001) 115 FCR 229, Black CJ and French J observed (at [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.
12 As noted in Horn v Australian Electoral Commission [2008] FCA 43 (at [20]), the opportunities to challenge the decisions of a Minister or Commonwealth agency does not mean that a Minister or such agency should be deprived of an order in respect of their costs (see Save The Ridge Inc v Commonwealth (2006) 230 ALR 411 (at [17]-[18]) and Williams v Minister for Environment & Heritage (2004) 132 LGERA 368 per Gray J with Tamberlin J in agreement (at [40])).
13 Espousing the public interest alone is not a grant of general immunity from costs (Oshlack per Kirby J (at 123)). There is no general principle from Oshlack that usual costs orders should not apply if the subject matter of the litigation is a matter of public interest (Ruddock (No 2) (at [21])). The appellant appears to accept and we give importance to the observation by Burchett J in Australian Conservation Foundation v Forestry Commission (Tas) (1988) 81 ALR 166 (at [171]) where his Honour observed that just because a body is set up to pursue causes which its founders consider to be in the public interest (and which indeed may be in the public interest), it does not follow that those against whom it proceeds in court should be deprived of the ordinary protection of a right to a costs order in their favour in the event that the claim prove unfounded.
