Samuel Muya Njuguna v Republic
The bottom line
#Kenya's Court of Appeal confirmed that a child aged 11 years and 10 months counts as 11, so the mandatory life sentence for defilement stands.
What this practically means
#Executive summary
#Key legal issues
#Identification of the offender
The appellant was properly identified; the complainant knew him previously and the offences occurred in broad daylight on three consecutive days
The complainant knew the appellant as a herdsman in the same locality, the incidents occurred in broad daylight giving ample opportunity to observe, and the assault was repeated over three days. The Court found no basis to doubt the honesty and capacity of PW1 and declined to disturb the concurrent findings of the two courts below.
Proof of penetration
Penetration was proved to the required standard by the complainant's testimony, corroborated by the mother and the clinical officer's findings
Section 2 of the Sexual Offences Act defines penetration as partial or complete insertion of genital organs, the anus included; neither spermatozoa nor ejaculation is required. PW1 gave a detailed graphic account, the mother noted behavioural changes, and the P3 findings were consistent with penetration. The concurrent findings stood.
Computation of the complainant's age and the alleged lacuna in Sections 8(2), (3) and (4) of the Sexual Offences Act
No lacuna exists; a child of 11 years and 10 months falls within Section 8(2) and attracts the mandatory life sentence
Applying the Age of Majority Act, the Interpretation and General Provisions Act and common law rules, age is attained at the close of the day preceding the anniversary of birth; fractions of a year are not recognised. Reading the provisions harmoniously with the Act's protective preamble, the Court followed Hadson Ali Mwachongo and declined to follow Alfayo Gombe Okello's lacuna reasoning.
Constitutionality of mandatory sentences under the Sexual Offences Act
The Muruatetu jurisdiction does not extend to Sexual Offences Act offences, so the mandatory life sentence challenge fails
The Court acknowledged the appellant's argument on mandatory sentences as attractive but held that the Supreme Court has clarified that Muruatetu does not apply to offences under the Sexual Offences Act, foreclosing the challenge to the mandatory life sentence.
Legal principles established
#- A second appeal is confined to matters of law and the Court will not interfere with concurrent findings of fact unless based on no evidence, a misapprehension of the evidence, or wrong principles
- In computing age under Section 8(2) of the Sexual Offences Act, a child aged 11 years and any number of months is treated as 11 years old until the day preceding the twelfth birthday; there is no lacuna between the age brackets in Sections 8(2), (3) and (4)
- Where there is an ambiguity in the phraseology of sentencing, the accused is entitled to the benefit of the least severe prescribed punishment
