JMO v Republic (Criminal Appeal E057 of 2023) [2026] KECA 1427 (KLR)
The bottom line
#Kenya's Court of Appeal reinstated a life sentence for incest, ruling that judges cannot swap charges for defilement when both carry equal punishment.
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 High Court was entitled to substitute a charge of incest contrary to section 20(1) of the Sexual Offences Act with that of defilement contrary to section 8(1) as read with section 8(2) of the Act
- 2.whether the ingredients of the offence of defilement or incest were established
- 3.whether an unlawful sentence was imposed
Key legal issues
#Whether the High Court could substitute a defilement conviction for incest under section 179 of the Criminal Procedure Code
No. Defilement was not a minor or cognate offence to incest because both carry a possible life sentence; the substitution was an error of law.
Section 179 permits conviction on a minor offence only where the offence proved is lesser than that charged. A cognate offence shares essential elements with the primary offence but differs in degree or severity. Incest under section 20(1) attracts a sentence of not less than ten years or life, while defilement under section 8(1) as read with 8(2) attracts a mandatory life sentence for a child under 11. Since the substituted offence was not minor to incest, the High Court could not rely on section 179 to swap the convictions, and its finding was set aside.
Whether the elements of incest were established despite the High Court's finding of no proof of paternity
Yes. The evidence showed the appellant was the husband of the complainant's mother, and the statutory presumption of knowledge of the relationship was never rebutted; 'father' includes a half-father.
PW2 and PW4 testified that the appellant was the husband of PW1's mother and that it was the mother who reported the defilement. The appellant himself admitted a dispute with his wife. Under section 22(3) of the Sexual Offences Act, the accused is presumed to know the relationship unless the contrary is proved; the presumption that he knew he was the stepfather was not rebutted. Section 22(1) defines father to include a half-father, a stepfather or a person standing in place of a father, so the trial court's conviction for incest was legally sound.
Whether the concurrent factual findings on age, penetration and identification should be disturbed
No. The court saw no basis to interfere with the concurrent findings that the complainant was four years old, penetration occurred, and she identified the appellant.
As a second appellate court, its jurisdiction is confined to matters of law under section 361(1) CPC. The concurrent findings of the trial court and the High Court on the complainant's age (four years, in baby class), the medical evidence of penetration from PW5, and PW1's recognition of the appellant were supported by the record and disclosed no error of law warranting interference.
Whether an unlawful sentence was imposed
No. The trial court's life sentence for incest, an offence for which the accused was liable to life imprisonment, was lawful and was reinstated.
The appellant's complaint about the excessiveness of sentence was, in any event, outside the court's second-appeal jurisdiction under section 361(1)(b) CPC, which prohibits appeals against sentence except where enhanced by the High Court. The trial court's sentence on the main count of incest was within the statutory prescription and was reinstated together with the conviction.
Legal principles established
#- In a second appeal, the Court of Appeal is confined to matters of law only; it may not re-evaluate facts or review the severity of sentence except where an error of law occurred
- A cognate or minor offence under section 179 of the Criminal Procedure Code must be lesser in degree or severity than the primary charge; where the substituted offence carries an equal or greater punishment, section 179 cannot be invoked to swap the charge
- Under section 22(3) of the Sexual Offences Act, an accused is presumed, unless the contrary is proved, to have known the relationship existing between him and the other party to the incest; under section 22(1), 'father' includes a half-father, being a stepfather or a person standing in place of a father
Court orders
#- 1.Appeal partially allowed by setting aside the decision of the High Court quashing the trial court's conviction and sentence on incest and substituting it with conviction and sentence for defilement contrary to section 8(1) of the Sexual Offences Act
- 2.The conviction and sentence of the trial court (incest, life imprisonment) reinstated

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.
The upshot is that we partially allow the appeal by setting aside the decision of the High Court quashing the conviction and sentence by the trial court on incest and substituting thereof with the conviction and sentence for the offence of defilement contrary to section 8(1) of the Sexual Offences Act. We instead reinstate the conviction and sentence of the trial court.
If the evidence proves the elements of incest and defilement and both charges carry similar or possibly similar sentence of life imprisonment, then section 179 of the Criminal Procedure Code could not possibly and simply be relied upon to swap the charges and convictions because the substitute offence of defilement was not minor to incest.
Further, under subsection 22(1) of the Sexual Offences Act, a father includes a half-father which means a stepfather or an individual who stands in place of a father including a mother’s partner.
Accordingly, we are satisfied that the High Court as the first appellate court erred in law when the learned Judge stated;
Our primary duty is to reach a legally sound finding.
Issues in the judgment
#The record refers to the appeal coming up for hearing on 29th April, 2026 and judgment delivered 10th July, 2026, but the respondent's written submissions are dated 28th April, 2026, a date after the appellant's submissions reference and immediately before the hearing date; the chronology is internally consistent but the case number of this appeal is not stated in the judgment.
The judgment quotes the High Court's quashed decision within its own text (order substituting conviction), which could be mistaken for the Court of Appeal's own order if read out of context.
