Government of Australia
The Commonwealth of Australia was formed in 1901 as a result of an agreement among six self-governing British colonies, which became the six states. The terms of this contract are embodied in the Australian Constitution, which was drawn up at a Constitutional Convention and ratified by the people of the colonies at referendums. The Australian head of state is the Queen of Australia who is represented by the Governor-General of Australia, with executive powers delegated by constitutional convention to the Australian head of government, the Prime Minister of Australia.
Reserved powers doctrine
The reserved powers doctrine was a principle used by the inaugural High Court of Australia in the interpretation of the Constitution of Australia, that emphasised the context of the Constitution, drawing on principles of federalism, what the Court saw as the compact between the newly formed Commonwealth and the former colonies, particularly the compromises that informed the text of the constitution. The doctrine involved a restrictive approach to the interpretation of the specific powers of the Federal Parliament to preserve the powers that were intended to be left to the States. The doctrine was challenged by the new appointments to the Court in 1906 and was ultimately abandoned by the High Court in 1920 in the "Engineers' Case", replaced by an approach to interpretation that emphasised the text rather than the context of the Constitution.
The Constitution sets up the Commonwealth of Australia as a federal polity, with enumerated limited specific powers conferred on the Federal Parliament. The constitutional convention held in Adelaide in 1897, passed a resolution that, as the first condition for the creation of a federal government, "the powers, privileges and territories of the several existing colonies shall remain intact, except in respect of such surrenders as may be agreed upon to secure uniformity of law and administration in matters of common concern." The intention of the framers of the Australian Constitution has been said to be "to create a federal government, albeit of limited jurisdiction, which would be responsive to the popular will in specified matters of national concern and to superimpose it upon existing colonial or state governments which were seen as each adequately responsive to the popular will within their respective territorial constituencies."
