Samuel Mburu Wanyoike v Republic [2018] KECA 350 (KLR)
The bottom line
#Kenya's Court of Appeal confirmed that partial penetration and victim testimony alone can prove defilement, dismissing the appeal and upholding a life sentence.
What this practically means
#Executive summary
#Key legal issues
#Whether penetration was proved as an ingredient of defilement
Penetration was proved to the required standard by the evidence of the complainant, her grandmother and the clinical officer who found partial penetration despite an intact hymen.
The Court, confined to questions of law on second appeal, found the concurrent findings of the two lower courts well supported. Section 2 of the Sexual Offences Act defines penetration as partial or complete insertion of genital organs. PW1 saw watery discharge; the complainant described pain; the clinical officer testified to tenderness and partial penetration. The appellant was also arrested at the scene.
Whether medical evidence or a DNA test linking the appellant to the offence was necessary
Medical evidence is not indispensable to prove defilement; oral evidence of the victim and circumstantial evidence suffice.
Relying on its own precedents, the Court held that defilement is complete upon partial or complete insertion of genital organs, and the fact of rape or defilement is proved by evidence, not by a DNA test. The absence of medical evidence linking the accused is therefore not decisive where there is credible direct or circumstantial evidence of penetration.
Whether Section 333(2) of the Criminal Procedure Code required the period in pre-sentence custody to be taken into account
The provision has no application to a life sentence because the term is indefinite and cannot practically be reduced by time already served.
The Court set out the proviso requiring a sentence to take account of the period spent in custody prior to sentence, but held it impractical to apply that deduction to a life sentence, which is indefinite rather than a fixed term. The complaint therefore did not arise on these facts.
Legal principles established
#- On a second appeal, the Court of Appeal is confined to matters of law and does not interfere with concurrent findings of fact of the two lower courts unless they were based on no evidence or the courts were plainly wrong.
- Penetration, whether partial or only on the surface, is sufficient to prove the offence of defilement.
- Medical evidence is not a mandatory requirement to prove defilement; the offence may be proved by oral evidence of the victim or circumstantial evidence.
- Section 333(2) of the Criminal Procedure Code, requiring credit for time spent in custody before sentence, does not apply to a sentence of life imprisonment.
