Joel Mwika v Republic
The bottom line
#Kenya's Court of Appeal confirmed a 20-year defilement sentence, ruling minors cannot consent and second appeals only review legal errors.

#Scope of the Court's jurisdiction on second appeal
The Court's remit is restricted to matters of law under section 361(1) of the Criminal Procedure Code; findings of fact by the two courts below are not disturbed absent no evidence or perversity
Relying on Hamisi Mbela Davis and M'Riungu v Republic, the Court held that where appeal is confined to questions of law, the appellate court must accept findings of fact of the lower courts and not convert findings of fact or mixed findings into questions of law. Concurrent factual findings that the appellant committed defilement were based on credible evidence and could not be disturbed.
Proof of the ingredients of defilement (age, penetration, identification)
Age was proved by the complainant's evidence, her mother's testimony and the health card; penetration was proved by the complainant's evidence corroborated by medical evidence; identification was proved as the appellant was well known to the complainant
Both subordinate courts made concurrent findings on the three ingredients. The medical examination by PW5 confirmed defilement through a perforated hymen, perineal bruises and discharge. The complainant knew the appellant from church and the youth group, and he did not dispute knowing her, indeed claiming she was his girlfriend. The Court found no reason to depart from those findings.
Capacity of a minor to consent
A 14-year-old minor lacks the freedom and capacity to consent under section 42 of the Sexual Offences Act; the claim that the child willingly engaged in the act was untenable
Section 42 defines consent as agreement by choice with freedom and capacity to choose. A minor is deemed incapable of consenting. The complainant, aged 14 and living with mental disability, lacked capacity. The appellant's defence of framing arising from a land dispute and of willing participation was rejected as ousted by strong prosecution evidence, consistent with the findings of both courts below.
Propriety of the sentence
The 20-year sentence was the lowest in the statutory band under section 8(3) of the Sexual Offences Act and was lawful; severity of sentence on second appeal is a question of fact under section 361(2)
Section 8(3) prescribes a minimum of twenty years for defilement of a child aged between twelve and fifteen years. The appellant received the minimum. Since severity of sentence is a question of fact outside the Court's law-only remit, and the sentence was lawful, there was no basis for interference despite the appellant's plea of rehabilitation.
