Secretary, Department of Planning and Environment v Namoi Valley Farms Pty Ltd (No 6)

The matter before the court was an appeal by the Secretary, Department of Planning and Environment against a decision of the Land and Environment Court of New South Wales. The dispute revolved around the granting of development approval by the Department for a project by Namoi Valley Farms Pty Ltd. The applicants sought to construct a series of water storage dams on their land in the Namoi Valley region of New South Wales. The primary legal issues were whether the Department had acted lawfully and rationally in granting the approval, and whether the applicants had complied with all relevant legislative and regulatory requirements.

The court was required to determine if the decision to approve the development was made in accordance with the relevant planning and environmental legislation. It had to consider whether the decision-making process was procedurally fair, if the relevant statutory criteria were appropriately applied, and whether there was any error in the interpretation of the law. Additionally, the court had to examine whether the applicants had provided sufficient evidence to support their application and if the potential environmental impacts of the project were adequately assessed and managed.

The court found that the Department's decision-making process was procedurally fair and that the statutory criteria were appropriately applied. The court determined that there was no error in the interpretation of the law and that the applicants had provided sufficient evidence to support their application. However, the court held that the Department had failed to adequately assess and manage the potential environmental impacts of the project, particularly concerning the potential effects on water resources and biodiversity. Consequently, the court allowed the appeal and set aside the development approval granted by the Department.

The court ordered that the development approval be set aside and that the matter be remitted to the Department for reconsideration in light of the court's findings. The court also directed that the Department consider the potential environmental impacts of the project more thoroughly, including the effects on water resources and biodiversity, before making a new decision. Furthermore, the court ordered that the applicants provide additional information and evidence to support their application, addressing the specific concerns raised by the court.
