Key legal issues
#Whether the 20-year sentence for defilement of a 14-year-old was harsh and excessive
The appeal on sentence was dismissed; the 20-year sentence, being the minimum prescribed by Section 8(3) of the Sexual Offences Act, was upheld as neither harsh nor excessive.
The appellant abandoned his appeal on conviction, leaving only sentence. Section 8(3) prescribes a minimum of 20 years for defilement of a child aged between 12 and 15. The trial court considered the complainant's age, the nature and gravity of the offence, and mitigation. The complainant was a vulnerable minor with no shown remorse or amends from the appellant. The court held that mandatory sentences offend the constitution only where they completely preclude judicial discretion, which was not demonstrated here. The sentence was therefore lawful and proportionate.
Whether mandatory minimum sentences under the Sexual Offences Act are unconstitutional for limiting judicial discretion
A mandatory minimum sentence is not unconstitutional merely because it limits discretion; unconstitutionality arises only where the prescribed sentence completely precludes the court from exercising any discretion in any circumstances.
Relying on the Muruatetu jurisprudence as applied in Christopher Ochieng v Republic, the court distinguished between a mandatory sentence that removes all discretion (potentially unconstitutional) and a minimum sentence that still allows a court to consider mitigating factors. In this case the trial court considered the age of the complainant, the nature of the offence and the gravity of harm, and the statute prescribes a floor rather than an invariable sentence, so there was no constitutional infirmity.
Legal principles established
#- On a second appeal under Section 361(1) of the Criminal Procedure Code, the Court of Appeal considers only questions of law and cannot interfere with findings of fact by the two lower courts unless they considered matters they ought not to have, failed to consider matters they should have, or were plainly wrong.
- A prescribed mandatory sentence is unconstitutional only where it completely precludes the court from exercising any discretion regardless of circumstances; where the statute prescribes a minimum sentence and mitigation was considered, an appellate court will not disturb the sentence.
- The 20-year minimum sentence for defilement of a child aged between 12 and 15 years under Section 8(3) of the Sexual Offences Act reflects clear legislative intent and does not, of itself, violate constitutional principles.

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.
Consequently, the appeal on sentence is hereby dismissed, and the sentence is upheld. Orders accordingly.
what renders a sentence unconstitutional is the fact that the prescribed mandatory sentence completely precludes the court from exercising any discretion regardless of whether or not the circumstances so require.
the mandatory 20year sentence for defilement involving a victim between the ages of 12 and 15 is a clear legislative intent.
By dint of the provisions of section 361 of the Criminal Procedure Code, we are enjoined to consider only matters of law.
Issues in the judgment
#The judgment does not state the case number of the present appeal, nor the case number or judge(s) of the High Court decision appealed from, and the coram gives only initial-based or full names inconsistently (DR. K. I. Laibuta vs F. OCHIENG).
