Clive Frederick Palmer and the State Of Western Australia

The High Court of Australia considered a dispute between Clive Frederick Palmer and the State of Western Australia concerning the validity of certain legislation enacted by the Western Australian Parliament. The core of the dispute revolved around the *Limitation of Liability for State Actions Act 2020* (WA) (the Act), which sought to limit the liability of the State and its officers for actions taken in response to the COVID-19 pandemic. Mr Palmer challenged the constitutional validity of this Act.

The primary legal issue before the High Court was whether the Act was invalid by reason of its inconsistency with Chapter III of the *Commonwealth Constitution*, specifically concerning the separation of powers and the judicial power of the Commonwealth. Mr Palmer argued that the Act, by purporting to extinguish or limit existing causes of action and preventing future claims against the State and its officers, interfered with the exercise of the judicial power of the Commonwealth and was therefore beyond the legislative power of the Western Australian Parliament.

In its reasoning, the High Court affirmed the fundamental principle of the separation of powers under the Australian Constitution. The Court held that the Act, by retrospectively extinguishing or limiting causes of action that could be the subject of judicial determination, impermissibly encroached upon the judicial power vested in the courts. The Court found that the legislative power of a State does not extend to dictating the outcome of existing or potential litigation or to preventing the courts from exercising their constitutional function of adjudicating disputes. Consequently, the Act was found to be invalid to the extent of its inconsistency with Chapter III of the *Commonwealth Constitution*.
