Section 75 of the Constitution of Australia provides that the High Court shall have original jurisdiction in matters including "(iii) in which the Commonwealth, or a person suing or being sued on behalf of the Commonwealth, is a party" and "(v) in which a writ of Mandamus or prohibition or an injunction is sought against an officer of the Commonwealth." Since this jurisdiction is conferred by the Constitution, it can be removed only by amending the Constitution, which requires a national referendum. Nor, by the same token, can it be restricted; for example, jurisdiction over decisions made under a particular statutory provision cannot be ousted by a privative clause. Section 76 of the Constitution allows the Commonwealth parliament to legislate for additions to the High Court's original jurisdiction; such additions can be removed or altered by repealing or amending that legislation.
