Section 1 of the Australian Constitution sets up a democratic legislature, the bicameral Parliament of Australia. This is the Queen and two houses, the Senate and the House of Representatives. Section 51 of the Constitution sets out the Commonwealth Government's legislative powers and gives certain powers and responsibilities (known as "heads of power") to the federal government. All remaining responsibilities are kept by the six States. Each State has its own constitution, so that Australia has seven sovereign Parliaments, none of which can take over the powers of any other. The High Court of Australia rules on any arguments between the Commonwealth and the States, or among the States, about their powers.
