Benson Waweru Mwithuka v Republic
The bottom line
#Kenya's Court of Appeal dismissed a defilement appeal, confirming that child-witness protections benefit the child, and life imprisonment could not be reduced.
What this practically means
#Executive summary
#Key legal issues
#Compliance with sections 31 and 32 of the Sexual Offences Act in the taking of the evidence of a vulnerable child witness
Section 32 has both substantive and procedural compliance aspects. The information required under section 32 is for the benefit of the vulnerable witness, not the accused, since section 31 excludes an accused person from the category of vulnerable witnesses. Compliance may be established from the record and the testimony even without express recording, and the failure, if any, caused no prejudice to the appellant.
The court analysed section 32(1) and (2), distinguishing the duty of the prosecution to inform the witness (or her parent, guardian or person in loco parentis) from the duty of the trial court to enquire whether the witness has been informed. It found the trial court conducted a voire dire, declared PW1 a vulnerable witness and appointed her mother as intermediary, and the mother's testimony showed she understood her role. Following M.M. v Republic, the object of intermediary proceedings is fairness to all parties and the welfare of the child, so a technical omission without prejudice cannot benefit the accused.
Whether the offence of defilement was proved — corroboration of the intermediary's evidence and proof of penetration
The offence was proved. Because PW1's evidence was taken through an intermediary, section 31(10) of the Sexual Offences Act barred conviction solely on the uncorroborated evidence of the intermediary; however, each element of the offence — age, penetration and identity — was corroborated by independent evidence, including the medical evidence of PW2 and the testimony of PW3.
The court adopted the definition of corroboration in Khalif Haret v Republic as evidence tending to confirm other evidence, not confirmation of everything. Age was proved by testimony and the clinic card; penetration was established by PW1's testimony read in the context of her age, the discovery by her mother of pain in her private parts, and the medical finding of a torn hymen, which the court held corroborated the intermediary's evidence; identity was not in issue given the parties were acquainted and related. The court concurred with the detailed findings of the learned Judge of the High Court on penetration.
Whether the Court of Appeal could interfere with the sentence of life imprisonment on a second appeal
No. Section 361(1)(b) of the Criminal Procedure Code bars a second appeal against sentence unless the sentence was imposed without jurisdiction or enhanced by the High Court; severity of sentence is a matter of fact outside the Court's remit, and the ground had not been raised before the first appellate court.
Relying on the Supreme Court's decision in Republic v Mwangi; Initiative for Strategic Litigation in Africa (ISLA) & 3 Others (Amicus Curiae), the court reaffirmed that the Court of Appeal's jurisdiction on second appeals is limited to matters of law and it cannot interfere with the High Court's decision on facts unless the courts below considered matters they ought not to have, failed to consider matters they should have, or were plainly wrong on the evidence as a whole. The appellant's complaint that the life sentence was harsh and excessive was a matter of fact and had not been raised or addressed by the first appellate court, so it fell outside the Court's jurisdiction.
Legal principles established
#- On a second appeal under section 361(1)(a) of the Criminal Procedure Code, the Court of Appeal's jurisdiction is confined to matters of law and it must defer to concurrent findings of fact by the two courts below unless those findings were made on no evidence, on a perversion of the evidence, or no tribunal properly directing itself would have made them.
- Under section 361(1)(b) of the Criminal Procedure Code, the Court of Appeal on a second appeal may not interfere with sentence unless the sentence was imposed without jurisdiction or was enhanced by the High Court; severity of sentence is a matter of fact outside the remit of a second appeal.
- Sections 31 and 32 of the Sexual Offences Act are protective provisions for the benefit of the vulnerable witness, not the accused; substantive and procedural compliance may be established from the evidence even where the record does not expressly record compliance, and a failure of strict compliance cannot be exploited by an accused where no prejudice results.
- Where a complainant's evidence is taken through an intermediary, section 31(10) of the Sexual Offences Act requires that an accused shall not be convicted solely on the uncorroborated evidence of the intermediary; corroboration means evidence tending to confirm other evidence and each element of the offence must be corroborated.
