#Executive summary
#Questions the Court framed

- 3.Whether the appellant's sentence was sound in law
Key legal issues
#Whether the prosecution proved the ingredients of defilement (age, penetration, identity) beyond reasonable doubt
Yes. Age was confirmed by testimony and the age assessment report; penetration was corroborated by medical evidence; recognition of the appellant as a paternal uncle and neighbour was reliable.
The Court held that the minor's age was settled by her testimony and the age assessment report produced by the clinical officer; medical evidence established penetration; and the familial relationship and ongoing sexual trysts made recognition reliable. Sections 48 and 77 of the Evidence Act answered the complaint about the document not being produced by its maker.
Whether the failure to call the minor's father and grandmother as witnesses was fatal
No. Section 143 of the Evidence Act requires no particular number of witnesses, and a conviction may rest on the victim's sole credible evidence under section 124.
The Court noted the complainant's sole evidence is sufficient if the court believes her and records its reasons; both courts found her truthful and consistent. The Bukenya adverse-inference argument failed because the missing witnesses' evidence was not shown to be essential or adverse.
Whether the mandatory life sentence under section 8(2) of the Sexual Offences Act is unconstitutional
No. Muruatetu I did not invalidate mandatory or minimum sentences under the Sexual Offences Act; the life sentence for defilement of a child aged eleven or below is lawful.
The Court relied on Muruatetu II and the Supreme Court's decision in Republic v Mwangi (ISLA), which clarified that Muruatetu I did not apply to the Sexual Offences Act and that statutory minimum sentences do not violate the Constitution, leaving courts no discretion to go below statutory minimums.
Legal principles established
#- In a second appeal the Court of Appeal is confined to matters of law and will not disturb concurrent findings of fact unless the courts below considered matters they should not have, failed to consider matters they should have, or were plainly wrong.
- A conviction in a sexual offence case may be sustained on the sole evidence of the victim under section 124 of the Evidence Act, provided the court records reasons for believing the victim.
- Recognition of an accused by a witness who knows him is more reliable than identification of a stranger, and no identification parade is required where the witness knew the accused.
- Courts are not at liberty to impose sentences below the statutory minimums set out in the Sexual Offences Act; the life sentence under section 8(2) is constitutional.

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.
Ultimately, the appeal on both conviction and sentence is devoid of merit, and is hereby dismissed.
From the foregoing, it is clear that the sentence of life imprisonment prescribed under Section 8(2) of the Sexual Offences Act remains lawful, constitutional, and binding upon trial courts.
both courts properly fell back to Section 124 of the Evidence Act which allows a court to convict an accused on the sole evidence of the victim in sexual ofience cases, provided that the trial court records reasons for believing that the victim was telling the truth.
Being a second appeal, we are restricted under section 362(1)(a) of the Criminal Procedure Code to considering matters of law only.
