Context: In South Africa, a "two apex" system existed from 1994 to 2013. The Supreme Court of Appeal (SCA) was created in 1994 and replaced the Appellate Division of the Supreme Court of South Africa as the highest court of appeal in non-constitutional matters. The SCA is subordinate to the Constitutional Court, which is the highest court in matters involving the interpretation and application of the Constitution. But in August 2013 the Constitution was amended to make the Constitutional Court the country's single apex court, superior to the SCA in all matters, both constitutional and non-constitutional.
