The Sixteenth Amendment of the Constitution of South Africa transferred Merafong City Local Municipality from North West to Gauteng, altering the boundary between the two provinces. It alters the sections of Schedule 1A to the Constitution that define the geographical areas of the two provinces. The amendment came about in response to the ongoing, and sometimes violent, protests by the people of Khutsong, which had previously been transferred from Gauteng to the North West by the Twelfth Amendment.
