 It declared the Union of South Africa to be a "sovereign independent state" and explicitly adopted the Statute of Westminster into South African law.It also removed any remaining power of the Imperial Parliament to legislate for South Africa, and ended the King's direct involvement in the granting of Royal Assent.The Statute of Westminster applied to South Africa without needing ratification from its Parliament (unlike the case in Australia and New Zealand), so the Status Act was not legally necessary to establish South Africa's sovereign independence.
