Motor Traffic Act (No 3) 1971 (ACT)

In the case before the Supreme Court of the Australian Capital Territory, the plaintiff sought a declaration that the Motor Traffic Ordinance 1936-1971 was invalid, arguing that it was beyond the legislative power of the Commonwealth. The plaintiff further sought an injunction preventing the Registrar of Motor Vehicles from enforcing the Ordinance and an order quashing certain decisions made under the Ordinance. The central legal issue before the court was whether the Motor Traffic Ordinance 1971, as amended, was validly enacted under the Federal Government's legislative powers. The court found that the Ordinance was validly enacted under the Federal Government's legislative powers as set out in section 51 of the Constitution, specifically the external affairs power and the territories power. The Ordinance was deemed necessary to implement international conventions and agreements concerning motor traffic and was relevant to the peace, order, and good government of the Australian Capital Territory. Therefore, the court dismissed the plaintiff's claims, holding that the Motor Traffic Ordinance 1971 was a valid exercise of the Federal Government's legislative powers. The court made no orders as the plaintiff's claims were dismissed.
