Notaras v Waverley Municipal Council & Anor

The applicants, Notaras, sought judicial review of a decision made by the respondent, Waverley Municipal Council, to refuse their development application for a dual occupancy dwelling. The second respondent, the Minister for Planning, was also involved. The applicants contended that the Council's decision was invalid due to a failure to properly consider the relevant planning controls and policies, specifically the Waverley Local Environmental Plan 1996 (WLEP 1996) and the Waverley Development Control Plan 1996 (WDCP 1996). The matter came before the High Court of Australia.

The central legal issue before the High Court was whether the Council had erred in law by failing to give adequate consideration to the provisions of the WLEP 1996 and the WDCP 1996 when determining the development application. Specifically, the applicants argued that the Council had misinterpreted or misapplied clauses relating to building height, site coverage, and the provision of open space, thereby rendering its decision unlawful. The Court was required to determine if the Council's assessment of the development against these planning instruments was so flawed as to constitute a reviewable error.

In their joint judgment, Heydon and Kiefel JJ found that the Council had indeed failed to properly consider the relevant planning controls. Their Honours observed that the Council's assessment of the proposed development against the WLEP 1996 and WDCP 1996 was superficial and did not engage with the specific requirements of those instruments. The Court emphasised that a decision-making authority must demonstrate a genuine and thorough consideration of all relevant planning controls and policies. The failure to do so, as occurred in this instance, amounted to an error of law. The Court concluded that the Council's decision was invalid.
