Hunter's Hill Council v Minister for Local Government; Lane Cove Council v Minister for Local Government; Mosman Municipal Council v Minister for Local Government; North Sydney Council v Minister for Local...

Four local councils, Hunter's Hill, Lane Cove, Mosman, and North Sydney, brought proceedings against the Minister for Local Government, challenging the validity of certain provisions of the Local Government Amendment (Council Mergers) Act 2016 (NSW). The councils argued that the Act unconstitutionally imposed a council merger process on them, contrary to section 109 of the Constitution. The matter was heard in the Supreme Court of New South Wales.

The primary legal issue before the Court was whether the provisions of the Act were valid and consistent with the Commonwealth Constitution, specifically section 109, which mandates that when a state law is inconsistent with a federal law, the federal law prevails. The councils contended that the Act was unconstitutional because it intruded on powers reserved to the states under the Constitution. The Minister for Local Government defended the Act, arguing that it was a valid exercise of the state's power to legislate on matters concerning local government.

The Court determined that the Act was a valid exercise of the state's legislative power. It held that the Act did not conflict with any federal laws and thus did not contravene section 109. The Court further found that the state had the authority to impose a council merger process as part of its broader regulatory framework for local government. The provisions of the Act were deemed to be within the scope of the state's legislative competence and did not infringe upon any reserved powers of the states.

The Court dismissed the claims brought by the councils, finding that the Act was valid and did not contravene the Commonwealth Constitution. Consequently, the orders of the Court reflected this decision, upholding the provisions of the Local Government Amendment (Council Mergers) Act 2016 (NSW). The councils' applications were dismissed with no orders for costs.
