The Statute of Westminster Adoption Act 1942 is an act of the Australian Parliament that formally adopted sections 2–6 of the Statute of Westminster 1931, an Act of the Parliament of the United Kingdom enabling the total legislative independence of the various self-governing Dominions of the British Empire. With its enactment, Westminster relinquished nearly all of its authority to legislate for the Dominions, effectively making them de jure sovereign nations. With the enactment of the Adoption Act, the British Parliament could no longer legislate for the Commonwealth without the express request and consent of the Australian Parliament. The act received Royal Assent on 9 October 1942, but the adoption of the Statute was made retroactive to 3 September 1939, when Australia entered World War II. The Act is more important for its symbolic value than for the legal effect of its provisions. While Australia's growing independence from the United Kingdom was well accepted, the adoption of the Statute of Westminster formally demonstrated Australia's independence to the world. Background Australia's progression to effective independence was gradual and largely without incident. New South Wales was founded as a British colony in Sydney in 1788. Other colonies split away from New South Wales or were separately established over the Australian continent in the ensuing decades. The colonies became self-governing during the second half of the 19th century, starting with Victoria in 1852, although well before this time, all of the colonies had non-elected Legislative Councils to advise their respective Governors on matters of administration. When the Commonwealth of Australia was formed with federation of the six colonies in 1901, following royal assent of the Commonwealth of Australia Act 1900, it became classified as a Dominion of the British Empire. This accorded Australia somewhat greater independence, though it was legally a self-governing British colony. After the end of World War I, each of the Dominions (including Australia, Canada, New Zealand and South Africa but not Newfoundland) independently signed the Treaty of Versailles, but under the collective umbrella of the British Empire. Each Dominion also became a founding member of the League of Nations in its own right. This was an important international demonstration of the independence of the Dominions. The Statute of Westminster During the 1926 Imperial Conference, the governments of the Dominions and of the United Kingdom endorsed the Balfour Declaration of 1926, which declared that the Dominions were autonomous members of the
