For a conviction based on a complainant's evidence alone in sexual offence cases under s 269 of the Criminal Procedure and Evidence Act, the evidence must be clear, satisfactory and credible. A sexual complaint must meet the requirements established in S v Banana: (1) it must be made voluntarily without leading, inducing or intimidating questions; and (2) it must be made without undue delay to the first person to whom the complainant could reasonably be expected to report. Failure to report at the earliest opportunity, particularly when police are present at the scene and during subsequent interactions, fundamentally undermines credibility and raises suspicion of fabrication. Where the State fails to lead evidence from the first recipient of a delayed complaint or explain the circumstances of the complaint, it fails to prove guilt beyond reasonable doubt and the accused must receive the benefit of the doubt.
