A government notice published on 6 November 1964 gave the names of 303 persons on whom banning notices under the General Laws Amendment Act of 1963 (the so-called 90 Day Act), consisting largely of amendments to the Suppression of Communism Act, had been served up to 30 April 1964. Of that total, 68 were listed Communists, but 235 were not. Amongst this last group have been Liberal Party members. The strict security legislation aroused huge protests. By the end of 1964, 671 persons had been charged with contravention of the security laws and the campaign of violence to overthrow the South African government had almost been broken. Nearly all the revolutionary leaders had either been banned, jailed or fled the country.
