Tuwei v Republic (Criminal Appeal 27 of 2013) [2023] KECA 1298 (KLR)
The bottom line
#Kenya's Court of Appeal upheld a defilement conviction but replaced the mandatory life sentence with 35 years, confirming judges must have sentencing discretion.
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 complainant's age was proved
- 2.Whether the life sentence meted on the appellant was imposed in a lawful manner
Key legal issues
#Whether the complainant's age was proved to the required standard
The appeal against conviction fails; the complainant's age of 10 years was proved by her voir dire testimony and the P3 form estimate by Dr. Birech.
Age is an essential ingredient of defilement that must be proved beyond reasonable doubt, but documentary evidence is not the only means of proof. Here, the complainant stated during voir dire that she was 10 years old, and the trial magistrate found she understood the oath. Dr. Birech's P3 form estimated the same age. These two strands of evidence were corroborated and sufficient.
Whether the mandatory life sentence under section 8(2) of the Sexual Offences Act was lawfully imposed
The appeal against sentence succeeds; the mandatory life imprisonment is set aside and substituted with 35 years' imprisonment, taking into account aggravating and mitigating factors.
Because both courts below treated the life sentence as mandatory, the legality of the sentence is a matter of law within the Court's jurisdiction. Following recent jurisprudence holding that mandatory minimum sentences are unconstitutional to the extent they oust judicial discretion, the Court weighed the aggravating factors (tender age, breach of trust) against mitigation (previous conviction not sexual, young children) and substituted 35 years.
Scope of the Court's jurisdiction on a second appeal
Severity of sentence is a matter of fact, not law, but where the sentence was imposed on a mistaken view that it was mandatory, the appeal against sentence becomes a matter of law.
Section 361(1) of the Criminal Procedure Code confines second appeals to matters of law; severity of sentence is ordinarily a question of fact. However, because the courts below held the life sentence to be mandatory, the legality of the sentence became a question of law, giving the Court authority to interfere.
Legal principles established
#- On a second appeal, the Court of Appeal's jurisdiction is confined to matters of law and it will not disturb concurrent findings of fact unless based on no evidence, a perversion of the evidence, or a misapplication of the law.
- The age of the victim is an essential ingredient of the offence of defilement which must be proved beyond reasonable doubt, and it may be proved by consistent and corroborated oral evidence or documentary evidence; a birth certificate is not the only means of proof.
- The mandatory nature of minimum sentences under the Sexual Offences Act is unconstitutional because it deprives trial courts of sentencing discretion, though in appropriate cases the minimum sentences may still be imposed.
Court orders
#- 1.The appeal against conviction is dismissed
- 2.The appeal against sentence is allowed to the extent that the sentence of life imprisonment is set aside and substituted with a sentence of 35 years' imprisonment
- 3.The sentence shall run from the date of the appellant's conviction by the trial court on February 29, 2012

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.
This is a second appeal and therefore the jurisdiction of this Court is limited to matters of law. The law is clear that severity of sentence remains a matter of fact and not law.
In its wisdom, Parliament chose to categorise the gravity of that ofience on the basis of the age of the victim, and consequently, the age of the victim is a necessary ingredient of the ofience which ought to be proved beyond reasonable doubt.
On the contention that the age of the complainant was not established, it is our considered view that age is not proved primarily by production of a birth certificate.
The general inclination is that mandatory sentences are unconstitutional because they take away a trial court’s discretionary power to pass the most appropriate sentence in the circumstances of a particular case.
The appeal against sentence is allowed to the extent that the sentence of life imprisonment is set aside and substituted with a sentence of 35 years’ imprisonment. The sentence shall run from the date of the appellant’s conviction by the trial court on February 29, 2012.
Issues in the judgment
#The judgment describes Julius Kitsao Munyeso as a case where the Court of Appeal found the life sentence unconstitutional, and notes the issue is pending before the Supreme Court; however, the Court in this judgment nonetheless substitutes the life sentence with 35 years without overruling the life sentence generally. This is reconcilable but reflects an unsettled area of law.
The respondent's counsel is recorded as referring to the Maingi decision (which declared mandatory minimum sentences unconstitutional) while urging that the life sentence be affirmed, which the Court implicitly declined to fully adopt.
