["MS Asike-Makhandia", "EC Mwita", "B Ongaya"]

The prosecution proved age, penetration, and the appellant’s identity through the complainant’s mother, medical evidence, and circumstantial evidence showing the child was last in the appellant’s custody; the alleged inconsistencies were minor and not fatal; and life imprisonment was the only lawful sentence prescribed by section 8(2) for defilement of a child aged nine months.

Derrick Sisia alias Kuka v Republic

Court

High Court

Case number

Criminal Appeal E015 of 2025

Judge

["JN Kamau"]

The prosecution proved age, penetration, and identification beyond reasonable doubt. The complainant’s evidence was consistent and corroborated by witnesses and medical evidence, identification was by recognition under moonlight of a known neighbour, and no DNA test was necessary on the facts. The sentence of life imprisonment was lawful under section 8(2) of the Sexual Offences Act and could not be interfered with by the High Court in light of binding superior authority.

Okitopus v Republic (Criminal Appeal E176 of 2022) [2026] KECA 1472 (KLR) (24 July 2026) (Judgment)

Court

Court of Appeal

Case number

Criminal Appeal E176 of 2022

Judge

["PM Gachoka", "WK Korir", "L Ndolo"]

The complainant’s testimony, corroborated by eyewitness accounts and medical evidence, proved penetration and identified the appellant as the perpetrator beyond reasonable doubt. The life sentence was lawful because section 8(2) of the Sexual Offences Act mandates imprisonment for life for defilement of a child aged eleven years or less, and the Court of Appeal had no jurisdiction to reduce it on a second appeal.

Juma v Republic

Juma v Republic (Criminal Appeal E034 of 2024) [2026] KECA 1304 (KLR) (10 July 2026) (Judgment)

Court

Court of Appeal

Case number

Criminal Appeal E034 of 2024

Judge

["AK Murgor", "KI Laibuta", "JM Ngugi"]

The appeal failed because the record showed the complainant was born on 27 March 2011 and was therefore 11 years old at the time of the offence, bringing the case squarely within section 8(2) of the Sexual Offences Act. The other elements of defilement were concurrently found proved on credible evidence, and no legal error justified interference on second appeal. The statutory life sentence under section 8(2) remained lawful and constitutional.

Mwangi v Republic

Mwangi v Republic (Criminal Appeal E060 of 2022) [2026] KEHC 9504 (KLR) (23 June 2026) (Judgment)

Court

High Court

Case number

Criminal Appeal E060 of 2022

Judge

["DKN Magare"]

The prosecution proved all elements of defilement beyond reasonable doubt: the complainant was seven years old, medical and testimony evidence established penetration, and the appellant was the perpetrator identified consistently by the child and corroborated by surrounding evidence. The alleged alibi did not place the appellant elsewhere at the material time and failed. The asserted inconsistencies were immaterial. The sentence of life imprisonment was mandatory under section 8(2) of the Sexual Offences Act and was therefore lawful.

Gituamba v Republic

Court

High Court

Case number

Criminal Miscellaneous Application E120 of 2023

Judge

["PN Gichohi"]

The High Court dismissed the application because it lacked jurisdiction to disturb a mandatory life sentence that had already been affirmed on appeal, and because the applicable Supreme Court authority left any redefinition of life imprisonment or alteration of section 8(2) of the Sexual Offences Act to Parliament, not the Judiciary.

Court

Court of Appeal

Case number

Criminal Appeal 40 of 2019

Judge

["M Ngugi", "PM Gachoka", "MB Kairaria"]

The Court found that the concurrent findings of the trial court and the High Court properly established the complainant's age, penetration, and the appellant's identity, and that the appellant's defence was considered and rejected. It further held that the mandatory life sentence was lawful and constitutional for defilement of a child aged eleven years or less. The appeal therefore failed on both conviction and sentence.

Case number

Criminal Appeal 98 of 2018

Judge

["P Nyamweya", "LA Achode", "JM Mativo"]

The complainant was proved to be six years old, penetration was established by direct testimony and medical evidence, and the appellant’s bare denial did not dislodge the prosecution case. The trial and first appellate courts properly evaluated the evidence, and the mandatory sentence of life imprisonment under section 8(2) of the Sexual Offences Act is lawful and constitutional.
