The Cape Provincial Council was the provincial council of the Cape Province of South Africa. It was created by the South Africa Act 1909, with effect from the formation of the Union of South Africa on 31 May 1910. The first election to the provincial council took place on 15 September 1910 (also the day of the South African general election, 1910).
The provincial council continued to exist until 1986, when its functions were transferred to a strengthened executive authority appointed by the State President. The province itself was disbanded in 1994, when the provinces were reconstructed.
The provincial council was composed of members elected, by the first past the post electoral system, from single member electoral divisions. Provinces (like Cape Province) with more than 25 general roll seats in the House of Assembly used the same boundaries for provincial council elections as well.
In addition to the general roll electoral divisions, some additional provincial council seats were created in Cape Province for periods when black and coloured voters were still enfranchised, but had been removed from the general roll. This policy was effected (for black voters) by the Representation of Native Act 1936 and (for coloured voters) by the Separate Representation of Voters Act 1951.
Originally the term of the provincial council was five years, from the first meeting of the council after it was elected. The administrator of the province fixed the date for the meeting, but the provincial council had to meet at least once a year. The South African Parliament could alter the term by legislation (as it did when the provincial elections due in 1941 were postponed until 1943), but there was no general power to dissolve a provincial council before its statutory term expired.
Under the Constitution and Elections Amendment Act 1973, the State President was given the power to dissolve the provincial councils at the same time as the House of Assembly, so that the subsequent provincial election could take place on the same day as a parliamentary general election.
Executive powers were shared by the administrator and an executive committee. This arrangement was neither the traditional 'Westminster' model (such as that which existed at the Union level of government) or a United States style separation of powers between the executive and legislative parts of the government.
