Bay Simmer Investments Pty Ltd v State of New South Wales

Bay Simmer Investments Pty Ltd appealed to the Court of Appeal of New South Wales against orders of the Land and Environment Court that dismissed its summons. The dispute concerned the validity of a development consent granted by the Minister's delegate for a project identified as State Significant Development (SSD) 6069.

The Court of Appeal was required to determine whether the development application was a "staged development application" under section 83B of the *Environmental Planning and Assessment Act 1979* (NSW), and consequently, whether section 79C of the Act applied to the application. A further issue was whether the consent authority was required to consider the "construction-related impacts" of the development when assessing the application.

The Court of Appeal reasoned that the development application was not a staged development application within the meaning of section 83B. It held that the consent authority had erred in its approach by not applying section 79C to the application, which necessitated consideration of construction-related impacts. The Court concluded that the development consent granted was invalid.

The appeal was allowed, and the orders of the Land and Environment Court were set aside. The Court of Appeal declared the development consent invalid, set it aside, and ordered that the State of New South Wales pay Bay Simmer Investments Pty Ltd's costs in both the Land and Environment Court and the Court of Appeal.
