of the Judiciary Act 1903. Whilst it may seem that the inclusion of constitutional matters in section 76 means that the High Court's original jurisdiction regarding constitutional matters could be removed; In practice, section 75(iii) (suing the Commonwealth) and section 75(iv) (conflicts between states) are broad enough that many constitutional matters would still be within jurisdiction. The original constitutional jurisdiction of the High Court is now well established: the Australian Law Reform Commission has described the inclusion of constitutional matters in section 76 rather than section 75 as "an odd fact of history." The 1998 Constitutional Convention recommended an amendment to the constitution to prevent the possibility of the jurisdiction being removed by Parliament. Failure to proceed on this issue suggests that it was considered highly unlikely that Parliament would ever take this step.

Appellate jurisdiction The court is empowered by section 73 of the Constitution to hear appeals from the Supreme Courts of the States and Territories; as well as any court exercising federal jurisdiction. It may also hear appeals of decisions made in an exercise of its own original jurisdiction.

Special leave may only be granted where a question of law is raised which is of public importance, involves a conflict between courts or "is in the interests of the administration of justice". Special leave hearings are typically presided over by a panel of two or three justices of the High Court. Parties are typically limited to an oral submission of 20 minutes, in addition to any written submissions. Appeals to the Privy Council Appeals to the United Kingdom's Privy Council was a notable controversy when Australia's constitution was drafted. Section 74 of the constitution as it was put to voters, stated that there would be no appeals to the privy council in any matter involving the Constitution of the Commonwealth or State Government. The section as enacted by the Imperial Parliament was different. It prohibited appeals on constitutional matters, excepting where the High Court certified it appropriate for the appeal to be determined by Privy Council. This occurred only once, and the High Court has said it would
