Key legal issues
#Whether the offence of incest was proved beyond reasonable doubt
Yes. The ingredients of penetration, relationship within prohibited degrees of consanguinity, and the victim's age were all established by consistent, mutually corroborative evidence.
PW2, a child of four to five years, gave clear testimony that the appellant inserted his 'susu' into her vagina. PW3 found the appellant and child undressed together. Medical evidence showed a perforated hymen, blunt trauma and discolouration of the labia minora, and red blood and pus cells on swab. Relationship and age were uncontroverted. The absence of spermatozoa was not fatal, penetration being provable by oral and circumstantial evidence.
Whether the appellant's defence was properly considered
Yes. Both courts below considered and rejected the frame-up defence, which was a mere denial unsupported by evidence.
The appellant claimed PW3 fabricated the charge after domestic quarrels, but did not address the actual date of the incident and produced no supporting evidence. Both the trial court and the first appellate court evaluated and rejected the defence. A trial court must consider a defence but may reject it where it raises no reasonable doubt; a bare denial cannot dislodge prosecution evidence.
Whether there is any basis for interfering with the conviction and sentence
No. The conviction was supported by evidence and the life sentence was lawful under section 20(1) of the Sexual Offences Act.
The offence involved defilement of a child aged four to five by her own father, an offence liable to life imprisonment. Following Wanjema v Republic, an appellate court interferes with sentence only where it is illegal, founded on wrong principles, or manifestly excessive. None of those circumstances was demonstrated, so both conviction and sentence were affirmed.
Legal principles established
#- On a second appeal the Court of Appeal is confined to matters of law and will not interfere with concurrent findings of fact unless based on no evidence.
- The evidence of a child victim in a sexual offence can sustain a conviction without corroboration if the trial court believes the child and records reasons for that belief under the proviso to section 124 of the Evidence Act.
- Absence of medical evidence or spermatozoa is not decisive of penetration, which may be proved by the victim's oral evidence or circumstantial evidence.
- A mere denial unsupported by evidence does not dislodge the prosecution case or avail an accused an acquittal.
- An appellate court will not interfere with a sentence unless it is illegal, founded on wrong principles, or manifestly excessive.
Court orders
#- 1.Affirmation of both the conviction and the sentence
- 2.Dismissal of the appeal in its entirety for lack of merit

Relief refused
#Setting aside the conviction for insufficiency of evidence of penetration
Penetration was proved by the complainant's testimony corroborated by PW3 and medical evidence; absence of spermatozoa not fatal
Remittal to the High Court for resentencing
The sentence of life imprisonment under section 20(1) of the Sexual Offences Act was lawful; no basis for interference demonstrated
Costs

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.
A second appeal must be confined to points of law and this Court will not interfere with concurrent findings of fact arrived at in the two courts below unless based on no evidence.
the absence of medical evidence to support the fact of penetration is not decisive, as the fact of penetration can be proved by the oral evidence of a victim or by circumstantial evidence.
In the result, we affirm both the conviction and the sentence, and dismiss the appeal in its entirety for lack of merit.
