Samuel Murithi Kanyi v Republic
The bottom line
#Kenya's Court of Appeal confirmed a life sentence for defilement of an 8-year-old, ruling mandatory life sentences remain lawful until the Supreme Court says otherwise.
What this practically means
#Executive summary
#Key legal issues
#Proof of the ingredients of defilement
Age (8 years, proved by P3 form and medical notes), penetration (medical evidence of bruises, bleeding, swollen vagina and perforated hymen) and identity (complainant identified the appellant the same day and remained credible) were all proved beyond reasonable doubt.
The court restated the conjunctive ingredients of defilement and tested each against the record. Age was supported by documentary medical evidence consistent with Mwalango Chichoro Mwanjembe. Penetration was established by the medical officer's findings made on the day of the offence. Identity was not in issue as the offence occurred in daylight and the minor pointed out the appellant the same day; her testimony withstood cross-examination.
Scope of a second appeal
As a second appeal, only matters of law fall for determination; concurrent factual findings will not be disturbed absent omission, commission, or plainly wrong conclusions.
Relying on section 361 of the Criminal Procedure Code and Manyeso v Republic, the court held that it does not revisit matters of fact unless the courts below considered matters they ought not to have considered, failed to consider matters they should have, or were plainly wrong on the evidence as a whole. No such error was demonstrated here.
Constitutionality of the mandatory life sentence under section 8(2) of the Sexual Offences Act
The life sentence was lawful and constitutional, following the Supreme Court's holdings in Republic v Joshua Gichuki Mwangi and Republic v Manyeso.
The court noted that section 8(2) of the Sexual Offences Act is couched in mandatory terms, so the trial court had no discretion. Following the Supreme Court's pronouncements, a life sentence is the only available sentence for the offence until the Supreme Court rules differently or Parliament amends the law. The sentence was therefore neither harsh nor unconstitutional.
Legal principles established
#- On a second appeal, the Court of Appeal is confined to matters of law and will not interfere with concurrent findings of fact of the two lower courts unless those courts considered matters they ought not to have, failed to consider matters they should have, or were plainly wrong.
- A mandatory sentence of life imprisonment for defilement under section 8(2) of the Sexual Offences Act is lawful and constitutional, per the Supreme Court's holdings, and is the only available sentence until the Supreme Court rules differently or the law changes.
- The evidence of a minor as a single identifying witness in a sexual offence can solely sustain a conviction where the court is satisfied the witness is telling the truth.
