Promenade Investments Pty Ltd v State of New South Wales

Promenade Investments Pty Ltd (the appellant) appealed to the New South Wales Court of Appeal against a decision of the Supreme Court of New South Wales. The dispute concerned the validity of a notice issued by the Minister for Planning and Environment under section 39(1) of the *Environmental Planning and Assessment Act 1979* (NSW) (the Act), which purported to revoke a development consent previously granted to the appellant. The appellant argued that the Minister's notice was invalid and that the development consent remained in force.

The central legal issue before the Court of Appeal was whether the Minister had the power to revoke a development consent under section 39(1) of the Act after the consent had been granted and the development had commenced. Specifically, the Court had to determine the scope of the Minister's power to issue a notice under that section and whether it could be exercised retrospectively to invalidate a consent that had already been acted upon.

The Court of Appeal, comprising Kirby P, Mahoney AP, and Meagher JA, held that section 39(1) of the Act did not confer power on the Minister to revoke a development consent once it had been granted and the development had commenced. Kirby P reasoned that the language of the section indicated a prospective operation, and that to interpret it as having retrospective effect would be to permit the Minister to invalidate rights that had already accrued. Mahoney AP and Meagher JA concurred, finding that the notice issued by the Minister was beyond his statutory power and therefore invalid. The Court applied principles of statutory interpretation, emphasizing that powers conferred by statute must be exercised within their express or implied limits, and that retrospective interference with vested rights is generally not permitted unless clearly indicated by the legislation.

The appeal was allowed, and the notice issued by the Minister under section 39(1) of the *Environmental Planning and Assessment Act 1979* (NSW) was declared invalid. The Court ordered that the development consent granted to Promenade Investments Pty Ltd remained in force.
