United Nations Security Council resolution 623, adopted on 23 November 1988, the Council noted with grave concern the death sentence imposed upon anti-apartheid activist Paul Tefo Setlaba, on the basis of "common purpose" in South Africa. The resolution at the meeting urgently called by Zambia strongly urged the Government of South Africa to commute Setlaba's sentence and stay his execution in order to further avoid aggravating the situation in South Africa.[1]
