21 April 1982
A Group Areas Amendment Bill, introduced on 7 March 1982 and enacted on 21 April, maintained the existing commitment to the principle of separate residential areas, schools and amenities for different races, but excluded sports venues from its provisions. It is assumed that this step was taken in an effort to ease restrictions on participation of South African sportsmen in international games.
