The Transvaal section of the Supreme Court dismissed an appeal by the African National Congress (ANC) Secretary-General Walter Sisulu against a six years sentence of imprisonment. Sisulu was arrested at Liliesleaf farm, Rivonia, under Section 17 Act 37/1963 and charged with sabotage and attempt to overthrow the government. The dismissal of his appeal meant that he would have to serve six years in prison.
