Although Federation made Australia independent of Britain, legally the Commonwealth was a creation of the British Imperial Parliament, through the "Commonwealth of Australia Constitution Act" 1900 (Imp), which applied to Australia. As a result, there was continued uncertainty as to whether British Imperial laws still applied to the Commonwealth. This was fixed by the "Statute of Westminster 1931", adopted by the Commonwealth via the "Statute of Westminster Adoption Act 1942". The Statute of Westminster freed the Dominions, including the Commonwealth, from Imperial laws and controls. Legally, this is the moment of Australia's national independence.
