FSW v Republic (Criminal Appeal 3 of 2020) [2026] KECA 1190 (KLR)
The bottom line
#Kenya's Court of Appeal upheld a life sentence for incest, clarifying that life imprisonment for this crime is discretionary, not automatically mandatory.
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 the offence of incest (kinship, age of complainant, penetration/indecent act, and identity of the culprit) to the required standard
- 2.Whether the charge sheet was defective
- 3.Whether the appellant's rights under Article 50 of the Constitution were violated
- 4.Whether the appellant's defence was considered by the courts below
- 5.Whether the sentence of life imprisonment was lawful and appropriate, given the interpretation of the proviso to section 20(1) of the Sexual Offences Act
Key legal issues
#Ingredients of the offence of incest and sufficiency of proof
The ingredients are kinship within the prohibited range, age of the complainant, penetration or an indecent act, and identity of the culprit; all were proved beyond reasonable doubt on the evidence.
The complainant and her mother established paternity, which the appellant did not deny. Age was proved through the mother's testimony corroborated by the P3 form, PRC form and age assessment report. The complainant's consistent testimony, corroborated by medical evidence of an old broken hymen, established penetration and identity, qualifying under section 124 of the Evidence Act.
Scope of second appellate jurisdiction
As a second appellate court, the Court concerns itself only with matters of law under section 361(1)(a) of the Criminal Procedure Code; the appellant's grounds were primarily issues of fact.
The Court restated the settled principle that fact issues are settled by the trial court and first appellate court, and interference lies only where the lower courts considered matters they should not have, failed to consider matters they should have, or were plainly wrong. The memorandum of appeal raised primarily factual complaints, which could not succeed on second appeal.
Mandatory versus discretionary life sentence for incest under the proviso to section 20(1) of the Sexual Offences Act
The proviso to section 20(1) creates no mandatory minimum; 'shall be liable to imprisonment for life' confers a discretion to impose between ten years and life imprisonment.
Following M K v Republic, the Court contrasted section 8(2), which mandates life imprisonment for defilement of a child of eleven years or less, with the proviso to section 20(1), which uses 'shall be liable'. Adopting Opoya v Uganda, 'shall be liable' denotes a maximum, preserving sentencing discretion between ten years and life. Nonetheless, the life sentence imposed was affirmed as appropriate on the facts.
New grounds (defective charge sheet; Article 50 violations) raised for the first time on second appeal
Grounds not canvassed before the High Court and not elaborated on appeal fail.
The Court noted that the defective charge sheet and Article 50 grounds were neither raised before the High Court nor supported by elaboration before it, and the respondent additionally argued the charge sheet ground was not raised in the first appellate court. The appeal on those grounds was therefore rejected without further analysis.
Appropriateness of the life sentence on the facts
The trial court properly considered aggravating factors and mitigation; the life sentence was appropriate and is affirmed.
Although the proviso is discretionary, the sentencing court properly weighed the aggravating circumstances - repeated sexual assault of the appellant's own 14-year-old daughter and his role in procuring her abortion - together with mitigation. Both courts below correctly applied the law, and the Court of Appeal declined to interfere with the sentence.
Legal principles established
#- In a second appeal, the Court of Appeal is confined to matters of law and will not interfere with findings of fact unless the courts below considered matters they should not have, failed to consider matters they should have, or were plainly wrong on the evidence.
- The proviso to section 20(1) of the Sexual Offences Act does not create a mandatory minimum sentence of life imprisonment for incest with a victim under eighteen; it confers a discretion on the sentencing court to impose any term between ten years and life imprisonment.
- The age of a complainant in a sexual offences case may be proved by means other than a birth certificate or baptism card; failure to produce those documents is not fatal to the prosecution case.

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 conclusion, we find that this appeal has no merit and it is dismissed in its entirety. It is so ordered.
we are satisfied that the sentence stipulated in the proviso to Section 20 (1) of the Sexual Offences Act is not a minimum mandatory sentence of life imprisonment.
In a second appeal like this, by dint of section 361(1)(a) of the Criminal Procedure Code, this Court concerns itself only with matters of law, the issues of fact having been settled in the two courts below.
the failure by the prosecution to adduce a birth certificate or baptism card was not fatal to the case as age can be proved by other means.
This is not an issue for determination in this appeal, and we leave it for determination when it arises.
Issues in the judgment
#The judgment states the appeal 'was canvassed by way of written submissions on 17th March 2026', which is consistent with the delivery date of 26 June 2026, but the submissions of the respondent are dated 10th March 2026 while the appellant's submissions are undated; no material contradiction identified.
