The Constitution vests in the Parliament the legislative power of the Common- wealth. The legislature is bicameral, which is the term commonly used to indicate a Parliament of two Houses. Although the Queen is nominally a constituent part of the Parliament the Constitution immediately provides that she appoint a Governor-General to be her representative in the Commonwealth.3 The Queen's role is little more than titular as the legislative and executive powers and functions of the Head of State are vested in the Governor-General by virtue of the Constitution4, and by Letters Patent constituting the Office of Governor-General.5 However, while in Australia, the Sovereign has performed duties of the Governor-General in person6, and in the event of the Queen being present to open Parliament, references to the Governor- General in the relevant standing orders7 are to the extent necessary read as references to the Queen.8 The Royal Style and Titles Act provides that the Queen shall be known in Australia and its Territories as: Elizabeth the Second, by the Grace of God Queen of Australia and Her other Realms and Territories, Head of the Commonwealth.9 There have been 21 Governors-General of Australia10 since the establishment of the Commonwealth, seven of whom have been Australian born. The Letters Patent, of 29 October 1900, constituting the office of Governor- General, 'constitute, order, and declare that there shall be a Governor-General and Commander-in-Chief in and over' the Commonwealth. The Letters, inter alia, make provision for the appointment of a Governor-General from time to time and provide that the Governor-General shall be keeper of the Great Seal of the Commonwealth. They recognise that 'certain powers, functions, and authorities were declared to be !
