The Supreme Court of Western Australia is the highest state court in the Australian State of Western Australia. It has unlimited jurisdiction within the state in civil matters (although it usually only hears matters involving sums of A$750,000 or more), and hears the most serious criminal matters.
The Principality of Hutt River, often referred to by its former name, the Hutt River Province, was a micronation in Australia, proclaimed on 21 April 1970 when farmer Leonard Casley declared his farm to be a sovereign state, the "Hutt River Province". He claimed to have seceded from Australia, which occurred during his dispute with the authorities concerning wheat production quotas. A few years later, Casley began styling himself as "Prince Leonard" and granting family members royal titles, although he did not include the word "principality" in the official name until 2006. In 2017, Casley's claim to rulership was taken over by his son Graeme, who dropped the claim to sovereignty on 3 August 2020.
The claimed territory was located 517 km (321 mi) north of Perth, near the town of Northampton in the state of Western Australia. It had an area of 75 square kilometres (29 sq mi), making it larger than several recognised countries. It was not recognised as a country by the Australian Government nor any other national government, and the High Court of Australia and Supreme Court of Western Australia rejected submissions arguing that it was not subject to Australian laws.
The Government of Western Australia, also known as the WA Government, is the executive branch of government for the Australian state of Western Australia. It comprises the State Cabinet, Executive Council and the public sector. The WA Government includes approximately 130 agencies and authorities delivering frontline and support services, employs approximately 240,000 people and had an expected operating expenditure of A$43.59 billion in the 2024–25 financial year.
The state's founding constitution was enacted in 1890, with the state being a democratic constitutional monarchy. Since federation in 1901, Western Australia has been a constituent state of the Commonwealth of Australia, and the Commonwealth Constitution regulates its relationship with the Australian Government. The legislative branch takes the form of the bicameral Parliament of Western Australia, comprising the Legislative Assembly (lower house), Legislative Council (upper house), and the monarch of Australia represented through the Governor. The judicial branch comprises the Supreme Court of Western Australia and the lower courts.
