Lane Cove Council v RTA

Lane Cove Council brought proceedings against the Roads and Traffic Authority (RTA) challenging the RTA's decision to alter signage that had been installed by the Council, which changed the traffic flow on a road from two-way to one-way, and erected a "No Entry" sign. The Council argued that the RTA had no authority to change the signage without consulting the Council, which had initially approved the installation of the signs. The case was heard by the Supreme Court of New South Wales. The central issue before the Court was whether the RTA had the power to alter traffic control measures that had been put in place by a local council. The Council contended that under the Roads Act 1993, the power to construct and maintain traffic control facilities lay with the local authority, while the RTA's role was limited to constructing and maintaining roads. The Court held that the RTA did indeed possess the authority to alter the signage, as the Act conferred upon the RTA the power to control traffic and to make changes to traffic signs where necessary for safety reasons. The Court found that the RTA's actions were within its statutory powers and did not require the approval of the local council. The Court further noted that the RTA had the discretion to make changes to traffic control measures to ensure the safety of road users. The Supreme Court therefore dismissed the Council's claim.
