Caleb Okumu Oungo v Republic
The bottom line
#Kenya's Court of Appeal upheld a life sentence for defilement, confirming that DNA evidence is not required to secure a conviction.
What this practically means
#Executive summary
#Key legal issues
#Proof of the victim's age
Age of four and a half years was proved by the father's testimony and the birth certificate produced by the mother
The court applied the settled principle that age may be proved by documents or oral evidence of parents or guardian. The father testified the child was born in May 2013 and the mother produced the birth certificate, consistent with an age of four and a half years at the time of the offence. This constituted sufficient credible and reliable evidence of age.
Proof of penetration
Penetration was proved by the complainant's testimony corroborated by medical evidence of lacerations and a broken hymen
Relying on Bassita vs. Uganda, the court held that penetration may be proved by direct or circumstantial evidence and medical corroboration, though desirable, is not mandatory. MAA's evidence of pain was consistent with the clinical officers' and doctors' findings of lacerations and a broken hymen, establishing penetration beyond reasonable doubt.
Identification of the perpetrator and corroboration
Identification was by recognition and was proper; absence of DNA testing does not negate the case
MAA identified the appellant as the 'uncle' who lured her with chips and took her to his house, pointing him out to her father. The court applied Waingwe vs. Republic on the superiority of recognition evidence and IMA vs. Republic on DNA, holding section 36 of the Sexual Offences Act does not make DNA mandatory.
Constitutionality of the mandatory life sentence
The Court of Appeal lacks jurisdiction to interfere with the lawful mandatory sentence, and the issue was raised too late
Following the Supreme Court's decision in Republic vs. Mwangi (ISLA as amicus), the court held that as long as section 8 of the Sexual Offences Act remains valid, the mandatory minimum sentences remain lawful. Further, the appellant had not challenged constitutionality before the High Court and was precluded from raising it at this stage.
Legal principles established
#- A second appellate court is confined to matters of law and will not interfere with findings of fact unless no reasonable tribunal could have reached that conclusion
- Age of a defilement victim may be proved by birth certificate, baptism card, oral evidence of the child, parents, guardian or medical evidence, provided it is credible and reliable
- Penetration may be proved by direct or circumstantial evidence; the victim's evidence need not always be corroborated by medical evidence
- Absence of a DNA test does not negate the prosecution's case in a defilement charge
- Recognition of an assailant is more satisfactory and reliable than identification of a stranger
- An appellate court will not interfere with sentence unless it is manifestly excessive or the trial court acted on wrong principles or overlooked material facts
- Where the constitutionality of a mandatory minimum sentence was not raised before the trial court or the High Court, it cannot be raised for the first time before the Court of Appeal
