The case reaffirms the peremptory nature of sections 162–164 of the Criminal Procedure Act and underscores the duty of trial courts to properly determine the competence of child witnesses. It highlights the importance of a careful, child-appropriate enquiry into a witness’s understanding of the duty to speak the truth, the proper application of the cautionary rule in sexual offence cases involving child witnesses, and the need to avoid misdirections that undermine an accused’s right to a fair trial.
