Suppression of Communism Act, 1950
South African law, renamed the "Internal Security Act" in 1976

The Suppression of Communism Act, 1950 (Act No. 44 of 1950), renamed the Internal Security Act in 1976, was legislation of the national government in apartheid South Africa which formally banned the Communist Party of South Africa and proscribed any party or group subscribing to communism, according to a uniquely broad definition of the term. It was also used as the basis to place individuals under banning orders, and its practical effect was to isolate and silence voices of dissent.
Description
The Act, which came into effect on 17 July 1950, defined communism as any scheme aimed at achieving change—whether economic, social, political, or industrial—"by the promotion of disturbance or disorder" or any act encouraging "feelings of hostility between the European and the non-European races [...] calculated to further [disorder]". The Minister of Justice could deem any person to be a communist if he found that person's aims to be aligned with these aims, and could issue an order severely restricting the freedoms of anyone deemed to be a communist. After a nominal two-week appeal period, the person's status as a communist became an unreviewable matter of fact, and subjected the person to being barred from public participation, restricted in movement, or imprisoned.
The government justified passage of the Act by noting the involvement of members of the South African Communist Party in the internal resistance to apartheid, the subversive tactics of communist parties more widely, as well as the perceived threat of the Soviet Union in the emerging Cold War and decolonisation.
The opposition in the House of Assembly protested certain functions of the act, such as the possibility to ban individuals purposely advocating communist goals, circumventing the normal rule of law guarantees in the South African legal system. The government responded by watering down the act, explicitly outlining the right to due process before penalties (i.e. fines or imprisonment) were executed, requiring the Minister of Justice to submit requests to ban to a three-member committee, affording the right to redress by those issued a banning order, as well as exempting labour unions from the sanctions included in the act.

Why this record matters
The subject matters to the history & society register because the source frames it as south African law, renamed the "Internal Security Act" in 1976. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Jul 9, 2026. The linked authority identifier is Q1671012. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1950 and 1976.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
