8 It is common ground between the parties that the power to award costs arises pursuant to s 98 of the Civil Procedure Act 2005. However, the discretion to award costs must be exercised in accordance with r 3.7 of the Land and Environment Court Rules 2007 ("LEC Rules"). That rule applies to all proceedings in Class 1 of the Court's jurisdiction and provides:
"(1) …
(2) The Court is not to make an order for the payment of costs unless the Court considers that the making of an order as to the whole or any part of the costs is fair and reasonable in the circumstances.
(3) Circumstances in which the Court might consider the making of a costs order to be fair and reasonable include (without limitation) the following:
(a) that the proceedings involve, as a central issue, a question of law, a question of fact or a question of mixed fact and law, and the determination of such question:
(i) in one way was, or was potentially, determinative of the proceedings, and
(ii) was preliminary to, or otherwise has not involved, an evaluation of the merits of any application the subject of the proceedings,
(b) …"
9 Ms Duggan, counsel for the applicant, submits firstly on behalf of the applicant that the preliminary question before Jagot J falls squarely within r 3.7(3)(a) and that I should therefore conclude that it is fair and reasonable for me to award costs in favour of the applicant for the preliminary question determined by Jagot J. In support of this submission the applicant says that the question of permissibility was potentially determinative of the proceedings as between the parties in accordance with r 3.7(3)(a)(i). That is, if the question was determined in favour of the applicant then the issues raised by the respondent would be resolved. Alternatively, if the question was determined in favour of the Council the sub-division would not be permissible and the matter would not proceed to a hearing on the merits. The applicant also says that the circumstances satisfy r 3.7(3)(a)(ii) in that the question was preliminary to the evaluation of the merits of the development application by Commissioner Murrell at the consent orders hearing.
