North Sydney Council v Ligon 302 Pty Ltd

The dispute in *North Sydney Council v Ligon 302 Pty Ltd* concerned the validity of a development consent granted by North Sydney Council to Ligon 302 Pty Ltd for the construction of a residential flat building. The applicant, North Sydney Council, sought to challenge the consent, alleging it was invalidly granted. The matter was heard by the High Court of Australia.

The central legal issue before the High Court was whether the development consent granted by the Council was void *ab initio* due to a failure to comply with the procedural requirements of the relevant planning legislation, specifically concerning the notification of the development application. The Court was required to determine the consequences of such a procedural defect on the validity of the consent.

The High Court held that the development consent was invalid. Brennan CJ, Toohey and McHugh JJ reasoned that the Council had failed to give proper notice of the development application as required by the *Environmental Planning and Assessment Act 1979* (NSW). This failure was not a mere irregularity but a fundamental breach of a statutory requirement that went to the root of the Council's power to grant consent. Consequently, the consent was void from its inception, and the Council was entitled to have it declared invalid.
