The applicant was convicted of raping a 13-year-old and sentenced to imprisonment, caning and fines based on evidence from the victim (child), her mother (eyewitness) and a clinical officer (medical examiner) who produced a PF3. On appeal the Court of Appeal examined four complaints: lack of a voir dire for the child witness, the medical examiner’s qualifications, sufficiency of the prosecution case, and reliance on uncorroborated eyewitness evidence. The Court found that a clinical officer is competent to conduct the medical examination and complete the PF3. However, because the trial court failed to conduct the mandatory voir dire under section 127(2) of the Evidence Act, the victim’s unsworn evidence had to be expunged. With that evidence removed, the Court concluded the remaining testimony — the mother’s ocular account and the PF3 — did not prove penetration by the applicant or identify him as the perpetrator beyond reasonable doubt. The conviction was therefore unsafe. The Court allowed the appeal, quashed the conviction and set aside the sentence, ordering the applicant’s immediate release unless lawfully detained. Issues Whether the evidence of a child witness recorded without a voir dire examination is admissible and can be relied upon to convict the applicant? Whether a clinical officer is a qualified medical practitioner competent to examine a sexual offence victim and complete the PF3 form? Whether the prosecution proved the offence of rape beyond reasonable doubt where the victim's evidence is expunged? Whether the evidence of an eyewitness (mother) and medical report can, without the victim's evidence, satisfactorily establish penetration and identity of the perpetrator? Held The Court held that a clinical officer is a qualified and authorized medical practitioner competent to examine a sexual offence victim and to complete the PF3; therefore the appellant's complaint against the clinical officer's qualifications was without merit. The Court held that under section 127(2) of the Evidence Act (as then in force) a child of tender age must be subjected to a voir dire/test of competency and understanding before their unsworn evidence is received, and where there is a complete omission to conduct that enquiry the child’s testimony must be discounted/expunged. The Court held that, after expunging the victim's (child witness) evidence for failure to conduct the voir dire, the remaining evidence (the mother’s ocular account and the medical report/PF3) was insufficient to prove beyond reasonable doubt that the applicant committed the rape: the mother’s evidence did not satisfactorily establish penetration or identity from the distance and circumstances described, and the medical report proves sexual intercourse but not the identity of the assailant. Accordingly, the Court held that the conviction was unsafe and allowed the appeal, quashing the conviction and setting aside the sentence, ordering the applicant’s immediate release unless otherwise lawfully detained. Order The appeal is allowed; the conviction is quashed and the sentence set aside. The applicant is to be released from prison forthwith unless he is otherwise lawfully held.
Criminal law — medical evidence — Clinical officer competent to examine sexual offence victim and complete PF3 — sexual offences — medical report proves intercourse but not identity. Conviction unsafe where victim’s evidence is expunged and remaining evidence fails to prove penetration and identity beyond reasonable doubt — Victim’s testimony is best evidence Evidence — Child witness — mandatory voir dire — omission mandates discounting/expunging testimony
