Jansen v The State

The appellant, Cornelius Marthinus Jansen, was convicted in the Regional Court, Kempton Park, on two counts of contravening the Criminal Law Amendment (Sexual Offences and Related Matters) Act 32 of 2007. Count 7 alleged that between May 2008 and July 2008, the appellant unlawfully exposed his genitals to his minor child CJ, then three years old, by being naked in front of her, bathing with her, and rubbing his body and genitals with cream while she watched. Count 8 alleged that in July 2010, when CJ was five years old, the appellant sexually violated her by penetrating her vagina with his finger, or alternatively by touching, rubbing and pinching her vagina. He was acquitted on seven other counts. The appellant was sentenced to 10 years' imprisonment on count 7 and life imprisonment on count 8. The Gauteng Local Division dismissed his appeal against both convictions and sentences. He then appealed to the Supreme Court of Appeal with special leave. The State's case relied primarily on CJ's evidence as a single witness, aged six at trial, along with testimony from social workers, a district surgeon, and others. The appellant denied the allegations and presented evidence from a psychologist, social worker, and his then partner.

• Whether the State proved beyond reasonable doubt that the appellant exposed his genitals to CJ during May 2008 to July 2008
• Whether the State proved beyond reasonable doubt that the appellant raped or sexually assaulted CJ during July 2010
• Whether CJ's evidence as a single witness was satisfactory, reliable and truthful
• Whether the appellant's version could be rejected as false and not reasonably possibly true
• The proper judicial approach to evaluating evidence of a single witness in criminal proceedings

The appeal succeeded. The appellant's convictions on both counts 7 and 8 and the sentences imposed pursuant thereto (10 years' imprisonment on count 7 and life imprisonment on count 8) were set aside.

The binding legal principles established are: (1) Evidence of a single witness, while sufficient for conviction under section 208 of the Criminal Procedure Act, must be approached with caution and must be substantially satisfactory in every material respect; (2) In criminal proceedings, the standard of proof is beyond reasonable doubt - mere likelihood or speculation is insufficient; (3) An accused bears no onus to convince the court of the truthfulness of his or her explanation, and is entitled to an acquittal where the explanation tendered is reasonably possibly true; (4) Where a single witness provides contradictory accounts and implicates multiple different people in the same type of offence, this renders the evidence untrustworthy, less credible and unreliable; (5) Where there are alternative reasonable explanations for physical findings (such as self-inflicted injury), the court cannot conclude beyond reasonable doubt that only the accused could have caused such injuries; (6) Serious contradictions that go to the heart of a witness's evidence render that evidence insufficiently satisfactory to sustain a conviction.

The court noted that CJ was very young (three and five years old at the time of the alleged offences, six at trial), which contextualizes the evaluation of her evidence, though the court did not make any general observations about the competence or reliability of child witnesses as a class. The court also observed the problematic nature of the trial court's approach in count 7, where it stated "it is likely that the little girl must have seen her daddy's tottie on more than one occasion" - highlighting that likelihood is an insufficient basis for criminal conviction. The judgment also implicitly comments on the complexity of cases involving allegations of child sexual abuse where the child displays sexualized behavior, noting that such behavior may have multiple possible explanations including exposure to inappropriate conduct, coaching, or the child's own actions.

This case is significant in South African criminal law for reiterating and applying the principles governing single witness testimony in sexual offence cases. It emphasizes that while conviction on single witness evidence is permissible under section 208 of the Criminal Procedure Act, such evidence must be approached with caution and must be substantially satisfactory in every material respect. The case demonstrates the careful scrutiny required when the single witness is a young child and there are multiple contradictions in the evidence. It confirms that where a complainant makes contradictory allegations implicating multiple different people, and where there are alternative explanations for physical findings (such as self-inflicted injury through masturbation), the evidence cannot be considered sufficiently reliable for conviction beyond reasonable doubt. The judgment reinforces that an accused is entitled to acquittal where his or her explanation is reasonably possibly true, and that speculation or likelihood is insufficient to sustain a criminal conviction. The case serves as an important reminder of the evidentiary standards required in sexual offence prosecutions, particularly those involving child complainants.
