The High Court of Australia is the highest court in the Australian judicial system. Established in 1903, it serves as the final court of appeal and has the authority to interpret the Australian Constitution. The court's primary role is to ensure that laws are applied consistently and fairly across the country. The High Court consists of seven justices, including a Chief Justice. It hears cases on a range of issues, including constitutional matters, criminal law, and civil disputes. Its decisions are binding on all other Australian courts, making it a crucial institution for upholding the rule of law in Australia.
