St Alder & Ors v Waverley Local Council & Anor

The High Court of Australia, comprising French CJ and Kiefel J, considered a dispute between the St Alder group (the applicants) and Waverley Local Council and another party (the respondents). The proceedings concerned the validity of certain development consent conditions imposed by the Council.

The central legal issue before the High Court was whether the conditions imposed by the Council on the development consent were invalid for uncertainty. Specifically, the applicants argued that the conditions were so vague and imprecise that they failed to provide adequate guidance as to what was required for compliance, thereby rendering them legally unenforceable.

The Court's reasoning focused on the principles of certainty in administrative law. It was held that for a condition to be valid, it must be sufficiently clear and precise to inform the consent holder of their obligations. The Court examined the specific wording of the conditions in question and determined that they lacked the necessary clarity. Consequently, the Court found that the conditions were void for uncertainty, as they did not establish a discernible standard of performance or compliance.

The High Court made orders allowing the appeal and declaring the impugned conditions of the development consent invalid.
