Kirui v Republic (Criminal Appeal 50 of 2019) [2025] KECA 1086 (KLR)
The bottom line
#Kenya's Court of Appeal upheld a life sentence for defilement of a four-year-old, confirming mandatory sentences under the Sexual Offences Act remain lawful.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the prosecution proved the ingredients of defilement - age of the complainant, penetration and identity of the perpetrator - beyond reasonable doubt
- 2.Whether the charge sheet was incurably defective and the evidence marred by contradictions rendering the conviction unsafe
- 3.Whether the appellant's defence cast doubt on the prosecution case
- 4.Whether the sentence of life imprisonment under section 8(2) of the Sexual Offences Act was lawful, whether any notice of enhancement was required, and whether the mandatory life sentence is constitutional
Key legal issues
#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.

Quotable passages
#Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.
Accordingly, we afirm the conviction and uphold the sentence.
In the end, we find that the present appeal is unmerited.
By dint of the provision of section 361 of the Criminal Procedure Code, we are enjoined to consider only matters of law.
the prosecution must establish the following conjunctive ingredients: the age of the complainant, penetration, and the identification of the perpetrator
We have no discretion to reduce the sentence set out therein. We therefore find that the appeal against the sentence lacks merit and it is hereby dismissed.
Issues in the judgment
#The judgment is internally inconsistent on the complainant's age: the charge particulars state the child was 4 years old, while PW1 is recorded as testifying that she was 6 years old, though the Court nonetheless found age established as four years.
