The Judiciary Act 1903 regulates the structure of the Australian judicial system and confers jurisdiction on Australian federal courts. It is one of the oldest pieces of Australian federal legislation and has been amended over 70 times. Amongst other things, the Act regulates the exercise of the jurisdiction of the High Court of Australia, confers jurisdiction on the Federal Court of Australia, provides for the right of barristers and solicitors to practice in Federal courts, and establishes the Australian Government Solicitor.
