Vanderstock & Anor v The State of Victoria

The High Court of Australia heard an appeal in *Vanderstock & Anor v The State of Victoria*. The dispute concerned the constitutional validity of certain provisions of Victoria's *Climate Change Act 2022* (Vic) and the *Climate Change (Climate Change Council) Amendment Act 2022* (Vic). The appellants, Ms Vanderstock and Mr. Williams, challenged these laws, arguing they infringed upon the implied freedom of political communication protected by the Australian Constitution.

The central legal issue before the High Court was whether the impugned provisions of the Victorian legislation placed an unjustified burden on the implied freedom of political communication. Specifically, the Court had to determine if the Act's requirements for individuals and entities to disclose information about their greenhouse gas emissions, and the establishment of a Climate Change Council with certain advisory and reporting functions, were reasonably appropriate and adapted to serve a legitimate purpose in a manner compatible with the maintenance of the constitutionally prescribed system of representative and responsible government.

The Court ultimately found that the challenged provisions of the *Climate Change Act 2022* (Vic) and the *Climate Change (Climate Change Council) Amendment Act 2022* (Vic) did not impermissibly infringe the implied freedom of political communication. The majority reasoned that the laws were enacted for the legitimate purpose of addressing climate change, a matter of significant public concern and policy. The disclosure requirements and the Council's functions were considered to be reasonably proportionate means to achieve this purpose, and did not unduly restrict the capacity of individuals or groups to engage in political discourse concerning climate change policy. The Court emphasised that laws enacted for the purpose of addressing significant societal challenges, such as climate change, would generally be upheld unless they imposed a substantial and unjustified burden on political communication.
