This Act removed the requirement that internment be linked with states of emergency.
It amended five other Security Acts and embodied the 1967 Suppression of Communism Act with some amendments. The 'Sobukwe' clause for indefinite detention was deleted and a new provision for indefinite preventive detention was created instead. A Review Committee was established to review detentions within two months and could recommend further detention.
Prohibition of bail and detention of potential witnesses were provided for. Restrictions on movement of banned persons were included.
The Act was repealed by the Internal Security Act No 74 of 1982 and the Internal Security and Intimidation Amendment Act No 138 of 1991 except for s 10.
Section 10 was repealed by the State of Emergency Act No 86 of 1995.
