#Scope of second appellate jurisdiction
The Court is enjoined to consider only matters of law and will not interfere with concurrent findings of fact absent demonstrated misdirection or plainly wrong conclusions.
Section 361 of the Criminal Procedure Code confines a second appeal to questions of law. The Court adopted the Karani formulation: interference is permitted only where the two courts below considered matters they should not have, failed to consider matters they should have, or were plainly wrong on the evidence as a whole, in which case the error amounts to a matter of law. No such misdirection was demonstrated here.
Ingredients of defilement proved
Age, penetration and identity of the perpetrator were each established beyond reasonable doubt on the evidence of PW1, PW2 and PW7 and the P3 form.
The complainant's age of four years was corroborated by the mother, the clinician and the P3 form. Penetration was proved by the torn hymen and blood clots observed the same day, satisfying the definition in section 2 of the Sexual Offences Act. Identity was established by the complainant's testimony, her mother catching the appellant in the act, and his flight and arrest nearby. The appellant's unsworn defence was a mere denial.
Mandatory life sentence under section 8(2) of the Sexual Offences Act
The life sentence was lawful; it was not enhanced, and the Supreme Court's recent decisions affirm the mandatory nature of the sentence, leaving this Court no discretion to reduce it.
The trial court sentenced the appellant to life imprisonment and the High Court upheld, rather than enhanced, that sentence, so no notice of enhancement was required. Relying on the Supreme Court's decisions in Joshua Gichuki Mwangi and Manyeso, the Court held the mandatory life sentence under section 8(2) lawful, rejecting the submission that it is archaic or unconstitutional.
Legal principles established
#- On a second appeal under section 361 of the Criminal Procedure Code, the Court of Appeal is confined to matters of law and cannot interfere with findings of fact of the lower courts 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.
- A conviction for defilement requires proof, conjunctively, of the age of the complainant, penetration, and identification of the perpetrator.
- The mandatory life sentence under section 8(2) of the Sexual Offences Act is lawful, as affirmed by the Supreme Court, and the Court of Appeal has no discretion to reduce it.
