Khabbaz v State Planning Commission

This matter concerned an appeal by way of rehearing concerning the validity of decisions made by the South Australian Commission Assessment Panel (SCAP) regarding a proposed development. The appellant, RJK, challenged the primary judge's finding that SCAP's decisions were valid. The proposed development involved a 16-level building, 53.9 metres in height, to be constructed on a 569 square metre allotment within the Capital City Zone, adjacent to the Park Lands Zone and across a narrow lane from the City Living Zone.

The central legal issues before the court were the proper construction of the Development Plan (DP) and whether SCAP had erred in fact or law in its assessment of the development proposal. Specifically, the court was required to determine the extent to which SCAP, as a planning authority, was constrained by the DP when assessing a development application, and how it should approach inconsistencies within the DP.

The court affirmed the principles governing the assessment of development proposals by bodies like SCAP. It was held that such authorities are not rigidly bound by the DP in the same way as a standard administrative decision-maker. Instead, they exercise a broad discretion within the policy parameters of the DP, while still being required to have proper regard to its relevant provisions. The court emphasised that the task involves not only assessing the proposal against specific provisions but also distilling the overall intent and purpose of the zone, considering stated objectives and principles of development control. The ultimate criterion is whether the development is conducive to the desired character and amenity of the zone, and planning authorities may need to resolve inconsistencies within the DP by reference to these broader considerations.
