The respondent was convicted of rape in the Rustenburg Regional Court and sentenced to ten years’ imprisonment. During the trial, three state witnesses testified through an interpreter, and the oath was administered by the interpreter in the presence of the presiding magistrate. On appeal, the North West Division of the High Court held that this constituted an irregularity, found the witnesses’ evidence to be unsworn and inadmissible, and set aside the conviction and sentence. The State appealed to the Supreme Court of Appeal on a question of law concerning the interpretation of section 165 of the Criminal Procedure Act 51 of 1977.
