Lockyer Valley Regional Council v Westlink Pty Ltd

Lockyer Valley Regional Council sought leave to appeal a decision of the Planning and Environment Court that allowed Westlink Pty Ltd's appeal and approved its application for a development permit to construct a natural gas-fired electricity peaking station. The primary concern was the interpretation and application of section 3.5.14(2)(b) of the Integrated Planning Act, specifically whether the primary judge correctly assessed the conflict between the proposed development and the planning scheme, and if sufficient grounds existed to justify the development permit. The applicant argued that the primary judge misinterpreted the planning scheme, wrongly characterised the conflict, misapplied the legal test from Weightman v Gold Coast City Council, and failed to address certain arguments adequately.

The legal issues focused on whether the primary judge had erred in interpreting the planning scheme, correctly characterising the conflict, and applying the legal test for determining the sufficiency of grounds in the context of a conflict. The applicant also questioned whether the absence of negative impacts could be considered a ground and whether it was relevant that a public entity could have undertaken the same project. Additionally, the applicant contended that the primary judge did not adequately address the argument that the development could be accommodated on a designated industrial site in the regional plan. The court had to determine if there were material errors of law in the primary judge's decision.

The Court of Appeal granted the application for leave to appeal and allowed the appeal. It set aside the order of the Planning and Environment Court and remitted the appeal to that Court for redetermination. The Court found that the primary judge had indeed erred in his interpretation of the planning scheme and in characterising the conflict. Additionally, it was determined that the primary judge misapplied the legal test for determining the sufficiency of grounds and failed to consider relevant arguments. The Court ordered that the appeal be heard by a different judge and set out the costs to be borne by each party.
