#Proof of the essential ingredients of defilement
The prosecution proved the complainant's age, penetration and identification of the Appellant beyond reasonable doubt.
The Court reiterated that defilement under Section 8(1) of the Sexual Offences Act requires proof of the victim's age, penetration and identification of the perpetrator. The complainant's age was proved by her mother's evidence and an immunization card showing a birth date of 24th June 2005, corroborated by medical evidence and her teacher's testimony. Penetration was established by the complainant's testimony corroborated by the P3 and PRC forms showing a ruptured hymen and abrasions. The Appellant was positively identified through recognition, as he was known to the complainant as Peter.
Sufficiency of the immunization card as proof of age
The absence of the complainant's name on the immunization card did not render the proof of age unsafe where other credible evidence fixed her age.
The Appellant objected that the immunization card was unsigned, unnamed and only marked for identification. The Court held that age is not proved primarily by a birth certificate; the evidence of the mother who gave birth, supported by the doctor who examined the complainant, the complainant herself and a teacher's reference to her age, was sufficient. The concurrent finding that the complainant was 10 years old was not disturbed on second appeal.
Use of Section 124 of the Evidence Act to convict on uncorroborated child-victim evidence
The trial magistrate was entitled, having recorded reasons for believing the complainant, to convict on her sole evidence without the necessity of corroboration.
The proviso to Section 124 permits conviction on the sole evidence of the victim in a sexual offence where the court records reasons that it is satisfied the victim is telling the truth. The trial magistrate had ascertained the complainant as a competent and truthful witness. Here the evidence was in any event corroborated by medical evidence from Dr. Mohammed Monour, who found a ruptured hymen and abrasions and concluded there was penetration.
Recognition versus identification of the perpetrator
The Appellant was positively identified through recognition by the complainant, who repeatedly and firmly referred to him as Peter.
The complainant stated that the Appellant was well known to her and repeatedly referred to him as Peter, including when she told her teacher. The Court, applying Anjononi & others v Republic, held this was recognition, which is more satisfactory and reliable than identification of a stranger, depending as it does on personal knowledge of the assailant. The concurrent findings of the two courts below stood.
Fairness of trial under Article 50(2)(j) - access to the first report
Failure to provide the first report did not breach Article 50(2)(j) where the Appellant had the witness statements and cross-examined the witnesses without prejudice.
Article 50(2)(j) guarantees reasonable access to the evidence the prosecution intends to rely on, not a blanket right to all police information. The trial magistrate declined the request for the first report because witness statements had been supplied. The record showed the Appellant received those statements and ably cross-examined the prosecution witnesses, so the omission caused no prejudice and the ground failed.
Legal principles established
#- On a second appeal, the Court of Appeal is confined to matters of law and will not disturb concurrent findings of fact unless those findings are unsupported by evidence or the courts below misdirected themselves.
- Proof of a complainant's age in defilement cases may be by documentary evidence, oral evidence of the child, parents, guardian or medical evidence, provided the evidence is credible and reliable; a birth certificate is not the primary mode of proof.
- Under the proviso to Section 124 of the Evidence Act, a court may convict on the sole evidence of a child victim in a sexual offence if it records reasons that it is satisfied the victim is telling the truth.
- Recognition of an assailant known to the witness is more reliable than identification of a stranger.
- Article 50(2)(j) does not grant an accused a blanket right to access all information in police possession; the right extends to evidence the prosecution intends to rely on and any exculpatory material, and is qualified by reasonableness.
