SMN v Republic
The bottom line
#Kenya's Court of Appeal upheld a father's life sentence for defiling his six-year-old daughter, confirming DNA evidence is not required for defilement convictions.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether penetration of the complainant by the appellant was proved beyond reasonable doubt
- 2.Whether the prosecution evidence had probative value given the failure to call the Investigating Officer and absence of forensic/DNA testing
- 3.Whether the trial and first appellate courts failed to consider the appellant's defence
- 4.Whether the indeterminate life sentence under section 8(2) of the Sexual Offences Act is unconstitutional
Key legal issues
#Proof of penetration and identity in defilement
Penetration, identity of the perpetrator and age of the victim were proved beyond reasonable doubt by the complainant's testimony, corroborating witnesses and medical evidence
The complainant gave a detailed account of the sexual act, describing anal penetration and pain. Medical evidence showed anal and vaginal tears, bruising and discharge. The appellant was identified by PW1 and PW3 who saw him take the complainant away, and was known to all witnesses as her father.
Failure to call the investigating officer and absence of forensic/DNA evidence
Neither the absence of the investigating officer nor the lack of forensic or DNA testing undermined the conviction, as these are not essential elements of defilement
Section 143 of the Evidence Act requires no particular number of witnesses; the prosecution need only call sufficient witnesses to prove the charge. Where direct witness evidence is sufficient, failure to call the investigating officer causes no miscarriage of justice, and DNA evidence is not the only means of proving a sexual offence.
Constitutionality of the indeterminate life sentence under section 8(2) of the Sexual Offences Act
The life sentence is lawful; the Supreme Court did not invalidate minimum sentences in Muruatetu, and defining life imprisonment is a matter for Parliament, leaving this Court no jurisdiction to interfere
The Supreme Court in Muruatetu, Mwangi, Manyeso and Ayako affirmed that mandatory and minimum sentences remain constitutional and that setting the duration of a life sentence falls under legislative power. The Court of Appeal's contrary decision in Ayako was overturned by the Supreme Court.
Sufficiency of the appellant's defence
The appellant's defence was a mere denial that did not dislodge the evidence placing him with the victim and proving penetration
The appellant's claims of erectile dysfunction, being framed due to a marital grudge, and HIV status were unproved assertions raised without medical backing; they did not displace the direct and corroborated evidence of the prosecution witnesses.
Legal principles established
#- On a second appeal the Court is confined to matters of law under section 361 of the Criminal Procedure Code and will not interfere with concurrent findings of fact unless unsupported by the evidence
- Absence of forensic or DNA evidence does not vitiate a prosecution case for defilement or render a conviction unsafe; DNA testing under section 36(1) of the Sexual Offences Act is not mandatory
- Failure to call the investigating officer does not occasion a miscarriage of justice where the witnesses called sufficiently prove the charge and there is no evidentiary vacuum
- Life imprisonment under section 8(2) of the Sexual Offences Act remains lawful and constitutional; Muruatetu did not invalidate minimum sentences, and the duty to define the parameters of life imprisonment rests with Parliament

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.
We therefore have no jurisdiction to set aside or interfere with the sentence imposed on the appellant in light of the above-cited decisions by the Supreme Court, and can only observe that the appellant awaits a change in the law in this regard.
For these reasons, we uphold both the conviction of the appellant for the offence of defilement contrary to section 8 (1) and (2) of the Sexual Offences Act, and the sentence of life imprisonment. This appeal is accordingly dismissed in its entirety.
The absence of forensic or DNA evidence will therefore not vitiate the prosecution case or render a conviction unsafe.
By dint of the provision of section 361 of the Criminal Procedure Code, we are enjoined to consider only matters of law.
