It made similar amendments to the Defence Act to abolish capital punishment in the military justice system.
A schedule to the act contained similar amendments to laws of the formerly independent bantustans, which remained in force for their territories.
These mandatory sentencing provisions were initially to have effect only for two years, subject to extension by Presidential proclamation.
The act prescribes life imprisonment for certain convictions of murder or rape; subsequent amendments added certain terrorism-related crimes, genocide and crimes against humanity under the Rome Statute of the International Criminal Court, and human trafficking.
