Capital Territory (Self-Government) Act 1988. The Self-Government Act constitutes a democratic government for the Territory consisting of a popularly elected Legislative Assembly which elects a Chief Minister from among its membership who, in turn, appoints an Executive consisting of a number of Ministers. The executive power of the Territory rests with the ACT Government, led by the Executive. The Executive is chaired by the Chief Minister (currently the Labor Party's Andrew Barr) and consists of Ministers appointed by them. The Executive are supported by the ACT Public Service, which is arranged into directorates, and a number of public authorities. The Chief Minister is the equivalent of a State Premier and sits on the National Cabinet. Unlike the States and the Northern Territory, there is no vice-regal representative who chairs the Executive. The Chief Minister performs many of the roles that a state governor normally holds in the context of a state; however, the Speaker of the Legislative Assembly gazettes the laws and summons meetings of the Assembly. The legislative power of the Territory is vested in the unicameral Legislative Assembly. The Assembly consists of 25 members who are elected from five electorates using the Hare-Clark single transferable voting system. The Assembly is presided over by the Speaker (currently the Labor Party's Joy Burch). The Assembly has almost all of the same powers as the state parliaments, the power to "make laws for the peace, order, and good government of the Territory", with limited exceptions relating to the Territory's unique relationship with the Commonwealth. The Hare-Clark voting system was adopted after a referendum in 1992 and was entrenched by another referendum in 1995. The electoral system cannot be made except by a two-thirds majority in the Assembly or a majority vote of support at a public referendum. There is no level of local government below the Territory government as in the States and the functions associated with local government are carried out principally by the Transport Canberra and City Services Directorate. There is an indigenous voice to the ACT Government, called the Aboriginal and Torres Strait Islander Elected Body. Despite the wide powers of the Territory government, the federal government continues to have power over the Territory. This includes an unused power to dissolve the Assembly and appoint a caretaker government in extraordinary circumstances. The federal and territory governments share some officers, such as the Ombudsman. The federal parliament also retains
