Ngeno v Republic (Criminal Appeal 52 of 2019) [2025] KECA 1079 (KLR)
The bottom line
#Kenya's Court of Appeal dismissed a defilement appeal, confirming that a birth certificate alone can prove a child's age and that mandatory 20-year sentences 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 ingredients of the offence of defilement (age of the complainant, penetration, and identification of the perpetrator) were proved
- 2.Whether the failure to call W. as a witness was fatal to the prosecution's case
- 3.Whether the sentence of 20 years imprisonment was excessive or unlawful
- 4.Whether the evidence of the complainant was fatally received without voire dire examination
Key legal issues
#Proof of the complainant's age where documents conflict
The age of the complainant was proved by the birth certificate showing a date of birth of 17th January 2002, corroborated by the oral evidence of PW1 and PW2; inconsistencies in the P3 form and appointment card do not create reasonable doubt
The Court reaffirmed Mwalango Chichoro Mwanjembe and Hadson Ali Mwachongo: age may be proved by a birth certificate, baptism card, oral evidence of the child, parents, guardian or medical evidence. Where a birth certificate is produced as an exhibit the court need not look further. The birth certificate, showing birth on 17th January 2002, was specific and corroborated, so the trial and first appellate courts did not err in finding the complainant was 14 years old.
Whether penetration was proved despite the absence of DNA evidence tying the appellant to the pregnancy
Penetration was proved; pregnancy and paternity are not the only means of proving defilement, and the complainant's evidence, corroborated by the medical examination, established penetration
Following Williamson Sowa Mbwanga, paternity of the complainant's child is a different question from whether the accused defiled her. The proviso to section 124 of the Evidence Act permits conviction on the victim's evidence alone where the court is satisfied she is telling the truth, and section 36(1) of the Sexual Offences Act does not oust that provision. The complainant's narration and the clinical findings of PW3 established penetration beyond doubt.
Identification of the perpetrator and the defence of mistaken attribution
The appellant was positively identified: the complainant knew him, spent two nights in his house, and the defence of coercion by the father was an afterthought never raised in cross-examination
The complainant knew the appellant as an employee of their neighbour and narrated spending two nights with him at his house. The appellant's claim that W. had a relationship with the complainant was denied in cross-examination, and his claim that the complainant was coerced by her father was never put to any prosecution witness. The Court therefore found the identification proper and the defence an afterthought.
Failure to call W. as a witness
The failure to call W. was not fatal to the prosecution's case because the prosecution need only call witnesses sufficient to prove its case, and the evidence on record sufficed
The Court held that the learned Judge correctly appreciated the legal principles on the prosecution's duty regarding witnesses and properly applied them. Since the evidence already on record proved the offence against the appellant, the non-calling of W. could not vitiate the conviction. This aligns with Bukenya & others v Uganda and Julius Kalewa Mutunga as urged by the respondent.
Legality of the mandatory 20-year minimum sentence under the Sexual Offences Act
The sentence was legal and affirmed; the Court is bound by recent Supreme Court decisions upholding sentences under the Sexual Offences Act
Relying on Republic v Mwangi (ISLA), Republic v Ayako and Republic v Manyeso, the Court noted that the Supreme Court recently reiterated the legality of the sentences prescribed by the Sexual Offences Act, 2006. The Court of Appeal is bound to implement those sentences. Separately, a challenge to sentence severity would in any event fall outside section 361(1) as a matter of fact. The 20-year sentence was therefore lawful and affirmed.
Legal principles established
#- On a second appeal under section 361(1) of the Criminal Procedure Code, the Court of Appeal is confined to matters of law and may not interfere with findings of fact 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 birth certificate produced as an exhibit is the best evidence of a complainant's age in a defilement case; where it is produced, the court need look no further, though age may also be proved by other credible evidence
- Proof of penetration does not require pregnancy, DNA evidence or rupture of the hymen; the slightest penetration of the female sex organ by the male sex organ is sufficient to constitute defilement
- The prosecution is only obligated to call witnesses sufficient to prove its case; failure to call a particular witness is not fatal where the evidence on record establishes the offence
- Issues, including the absence of voire dire examination and the constitutionality of mandatory sentences, raised for the first time on a second appeal cannot be determined by the Court of Appeal
Court orders
#- 1.The appeal is dismissed in its entirety
- 2.The sentence of 20 years imprisonment imposed by the courts below is affirmed

- Section 361(1) of the Criminal Procedure Code (second appeal limited to matters of law)
Relief refused
#Reduction of the 20-year mandatory minimum sentence
The Supreme Court has reiterated the legality of sentences under the Sexual Offences Act; the Court of Appeal is bound to implement them, and sentence severity is a matter of fact outside its second-appeal jurisdiction
Setting aside the conviction on account of absence of voire dire examination of the complainant
The issue was raised for the first time in this Court and is barred on second appeal
Costs
No costs order recorded in the judgment
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.
In the end, we find the appeal lacking in merit and dismiss it in its entirety. It is so ordered.
This Court is therefore bound to implement the sentences as prescribed by the Act. It therefore follows that the sentence of 20 years imprisonment was legal, and we afirm it.
The key ingredients that must exist to found a conviction in an ofience of defilement are firstly, that the complainant is a child, secondly, that there was penetration, and thirdly, that the person charged was positively identified as the person who committed the ofience.
Where a birth certificate is produced as an exhibit, the Court needs not look further to ascertain the age of the complainant.
the prosecution is only obligated to call witnesses suficient to prove their case. In this case, as we have already held, the evidence on record proved the case against the appellant. The failure to call W. as a witness was therefore not fatal to the prosecution’s case.
we are barred from determining these issues on the basis that they have not been subjected to the constitutional and legal framework of the appellate system.
Issues in the judgment
#The judgment records the complainant's father as saying she went missing on 10th March 2002, which conflicts with the charge particulars dated 11th-12th March 2016; apparently a typographical error for 2016
The judgment does not state the appeal number of this second appeal, the case number in the High Court, or the trial court's case number
