The Supreme Court was first established in 1910 by the South Africa Act, which was passed by the Imperial British Parliament when South Africa achieved dominion status within the Empire. The Supreme Court Act (59 of 1959) set out to consolidate all the previous legislation and rules governing the Court and continues to serve as its primary constitutional authority. The Constitution Act (78 of 1995) further confirms the existence of the Supreme Court and states explicitly that the Court has no testing right over original legislation passed by Parliament. The Court does however have a testing right over delegated legislation, ordinances of the provinces and executive decrees, as these must be in line with Acts of Parliament.
