12 Furthermore, it was reasonably open for the Tribunal to exercise its discretion in relation to costs in the way in which it did. At the time the Commission lodged its statement of issues, facts and contentions with the Tribunal on 27 October 2008, the Commission considered, on its own assessment, that the proposed subdivision would adversely affect the rural landscape values of the site and surrounding locality. The Commission, therefore, expressly raised the issue of visual impact in its statement of issues, facts and contentions. However, in preparation for the hearing, the Commission engaged Ms Stephanie Clegg, a senior environmental planner with the Department for Planning and Infrastructure, to assess the extent of the perceived adverse impact of the proposed subdivision. Ms Clegg advised the Commission that any adverse impact could be obviated by conditions. In consequence of this advice, the Commission, promptly, filed an amended statement of issues, facts and contentions, withdrawing its contention that the proposed subdivision should not be approved because of its adverse visual impact.
