Concurrently, the Curtin government enacted the Statute of Westminster Adoption Act 1942, under which Australia accepted the dominion status which Britain had conferred in 1930, but which the Australian federal government had not accepted until then. The Adoption Act took effect retroactively as of 3 September 1939, the outbreak of World War II. Although politically a product of the government's policy of re-orientation towards the United States, constitutionally, this marked the moment that Australia became an independent nation with a separate Crown, no longer subject to the supremacy of British law and the British Crown.
