The respondent was convicted in the Nelspruit Regional Court of raping his 13-year-old niece and sentenced to life imprisonment. The conviction was based on the complainant’s testimony, corroborating evidence from her sister, medical evidence, and DNA evidence linking the respondent to vaginal swabs taken from the complainant. On appeal, the Gauteng Division of the High Court set aside the conviction and sentence, primarily on the basis that the State had failed to properly prove the chain of custody and authenticity of the DNA evidence, and released the respondent. The Director of Public Prosecutions then appealed to the Supreme Court of Appeal under s 311 of the Criminal Procedure Act 51 of 1977, contending that the High Court committed an error of law by ignoring material admissible evidence and the trial court’s findings.
