The Parliament of the United Kingdom passes the South Africa Act 1909, creating the Union of South Africa from the British Colonies of the Cape of Good Hope, Natal, Orange River Colony, and the Transvaal Colony.
The South Africa Act 1909 was an Act of the British Parliament which created the Union of South Africa from the British colonies of the Cape of Good Hope, Natal, Orange River Colony, and Transvaal. The Act also made provisions for admitting Rhodesia as a fifth province of the Union in the future, but Rhodesian colonists rejected this option in a referendum held in 1922. The South Africa Act was the third major piece of legislation passed by the Parliament of the United Kingdom with the intent of uniting various British colonies and granting them some degree of autonomy. Earlier, the British North America Act, 1867 had united three colonies (the Province of Canada (which was split into Ontario and Quebec) Nova Scotia, and New Brunswick) and the Commonwealth of Australia Constitution Act, 1900 had united the Australian colonies.
The Parliament of the United Kingdom is the supreme legislative body of the United Kingdom, the Crown dependencies and the British overseas territories. It alone possesses legislative supremacy and thereby ultimate power over all other political bodies in the UK and the overseas territories. Parliament is bicameral but has three parts, consisting of the sovereign (Crown-in-Parliament), the House of Lords, and the House of Commons (the primary chamber). Both houses of Parliament meet in separate chambers at the Palace of Westminster in the City of Westminster, one of the inner boroughs of the capital city, London.
The House of Lords includes two different types of members: the Lords Spiritual, consisting of the most senior bishops of the Church of England; and the Lords Temporal, consisting mainly of life peers, appointed by the sovereign, and of 92 hereditary peers, sitting either by virtue of holding a royal office, or by being elected by their fellow hereditary peers. Prior to the opening of the Supreme Court in October 2009, the House of Lords also performed a judicial role through the Law Lords.
The House of Commons is an elected chamber with elections to 650 single-member constituencies held at least every five years under the first-past-the-post system. By constitutional convention, all government ministers, including prime minister, are members of the House of Commons or, less commonly, the House of Lords and are thereby accountable to the respective branches of the legislature. Most cabinet ministers are from the Commons, whilst junior ministers can be from either house.
With the global expansion of the British Empire, the UK Parliament has shaped the political systems of many countries as ex-colonies and so it has been called the "Mother of Parliaments".In theory, the UK's supreme legislative power is officially vested in the Crown-in-Parliament. However, the Crown normally acts on the advice of the prime minister, and the powers of the House of Lords are limited to only delaying legislation; thus power is de facto vested in the House of Commons.
