Costs
35 As the applicants have been unsuccessful in their claims, the respondents seek an order for the payment of costs against the unsuccessful applicants. The applicants submit that the proper order in the circumstances of these proceedings is that each party should pay their own costs. The applicants rely on the public interest nature of the litigation. However, Hill Top Residents Action Group does seek an order that the proponent, the second respondent, pay Hill Top Resident Action Group's costs in relation to the proponent's defence of estoppel that was not pressed by the proponent at the hearing. The proponent submits that its decision not to press its estoppel defence was a sensible response to the commencement of fresh proceedings by the other applicant, Ms Strang, on the Friday before the hearing so as to render futile the proponent's estoppel defence against Hill Top Residents Action Group.
36 In my opinion, the proper order is that each party pay their own costs of each proceeding.
37 The power of the Court to order costs is in s 98 of the Civil Procedure Act 2005. Section 98(1) provides that, subject to rules of court, costs are in the discretion of the Court. The relevant rules of court include Pt 42 of the Uniform Civil Procedure Rules 2005 ("UCPR"). Part 42 r 42.1 provides that if the Court makes any order as to costs, the Court is to order that the costs follow the event unless it appears to the Court that some other order should be made as to the whole or any part of the costs. The Land and Environment Court has adopted specific court rules, including in relation to costs of proceedings in Class 4 of its jurisdiction, which can prevail over r 42.1 of the UCPR to the extent of any inconsistency between them: Civil Procedure Act, s 11 and UCPR, r 1.7 in Schedule 2. Part 4 r 4.2(1) of the Land and Environment Court Rules 2007 provides:
"The Court may decide not to make an order as for the payment of costs against an unsuccessful applicant in any proceedings if it satisfied that the proceedings have been brought in the public interest."
38 This rule is applicable to proceedings in Class 4 of the Court's jurisdiction. The present proceedings are in Class 4.
39 In Caroona Coal Action Group Inc v Coal Mines Australia Pty Limited and Minister for Mineral Resources (No 3) [2010] NSWLEC 59; (2010) 173 LGERA 280, I reviewed the authorities on the awarding of costs in public interest litigation. That review revealed that courts have used, in effect, a three step approach in determining whether to depart from the usual costs rule: first, can the litigation be characterised as having been brought in the public interest?; secondly, if so, is there "something more" than the mere characterisation of the litigation as being brought in the public interest? and thirdly, are there any countervailing circumstances, including in relation to the conduct of the applicant, which speak against departure from the usual costs rule?
40 Applying this three step approach, first, I find that the proceedings were brought to uphold and enforce public law obligations under the Act and to ensure that the Minister's exercise of power under Part 3A of the Act was lawful. This constitutes a public interest of a sufficient kind so as to allow characterisation of the proceedings as being brought in the public interest.
41 Secondly, I find the nature, extent and other features of the public interest involved in the litigation are significant and constitute something more than the mere characterisation of the proceedings as being brought in the public interest. The applicants' claim, which was identical in the two proceedings, concerned the proper construction and operation of three statutory provisions, s 75J(3) and s 75R(3) of the Act and cl 8O(1)(b) of the Regulation, which are pivotal to the process of deciding an application for approval of a project under Part 3A of the Act. The applicants' claim raised issues of statutory interpretation of general importance and the litigation has contributed, in a material way, to the proper understanding and administration of Part 3A of the Act. These circumstances have been recognised in the authorities as constituting something more than the mere characterisation of litigation as being brought in the public interest: see the authorities cited in 60 and (b) of Caroona (No 3). To these authorities may be added the recent decision in Gray v Macquarie Generation (No 2) [2010] NSWLEC 82.
42 Thirdly, there are no countervailing considerations that would lead the Court to order costs notwithstanding the public interest nature of the litigation. None of the countervailing considerations identified in the cases cited in [61] of Caroona (No 3) are applicable in these proceedings.
