23 December 1980
Four black newspapers, Post Transvaal, Saturday Post, Sunday Post and the Sowetan, were banned, technically on the same day that the eight week strike of black journalists ends. Six days later, in the Rand Supreme Court, Justice Coetzee, refused to lift the banning order on the four aforementioned newspapers. In addition to that, the security police served the president and vice-president of the Black journalists' trade union Media Workers of South Africa with three-year banning orders. A storm of protest erupted, even from the strongly pro-government Afrikaans press.
