The State v Nkulunkulu Sidney Katoo

The respondent was charged in the High Court, Port Elizabeth, with kidnapping and rape, alternatively sexual intercourse with an imbecile, arising from the disappearance of a 16-year-old complainant who was later found in his room and medically confirmed to have had recent sexual intercourse. The respondent admitted intercourse but alleged it was consensual and denied knowledge of the complainant’s mental incapacity. The State sought to call the complainant as a witness, but the trial court ruled her incompetent to testify under s 194 of the Criminal Procedure Act 51 of 1977 due to severe mental retardation. As a result, the respondent was acquitted on both counts. The State sought to reserve a question of law regarding the refusal to allow the complainant’s evidence.

The application to reserve the question of law was granted. The reserved question was answered in the affirmative. The respondent may be retried on count 2 (rape/sexual intercourse with an imbecile) in terms of s 324 of the Criminal Procedure Act. The acquittal on count 1 (kidnapping) stands and may not be retried.

The case clarifies the proper interpretation of s 194 of the Criminal Procedure Act and reinforces the presumption of witness competency in s 192. It confirms that mental retardation or imbecility does not automatically render a witness incompetent and emphasises the duty of trial courts to conduct a proper enquiry into competency. The judgment also underscores the obligation of lower courts to follow binding precedent and protects complainants’ dignity by reiterating limits on admissibility of sexual history evidence.
