BK v Republic
The bottom line
#Kenya's Court of Appeal upheld a life sentence for defilement of a nine-month-old, confirming that minor witness contradictions do not defeat a prosecution case.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the prosecution proved its case against the appellant
- 2.Whether the alleged contradictions and inconsistencies in the prosecution case undermined the prosecution case
- 3.Whether the sentence of life imprisonment was appropriate in the circumstances
Key legal issues
#Proof of the offence of defilement
The prosecution proved all essential ingredients: the victim was a child of nine months (oral testimony and birth notification), penetration (medical evidence of fresh lacerations, torn hymen and inflammation), and identity of the perpetrator (child last seen in the appellant's custody).
The court restated the elements of defilement under section 8(1) of the Sexual Offences Act and found concurrent findings by the trial court and first appellate court on age, penetration and identification. It held there was no misdirection in law in those findings, and that the child being the appellant's daughter who had spent a night with him reinforced identification.
Effect of contradictions and inconsistencies in prosecution evidence
The alleged contradictions were minor, did not go to the root of the prosecution case, and were not fatal; the core evidence of PW1 and PW2 remained consistent and credible.
Applying Twehangane Alfred v Uganda and Phillip Nzaka Watu v R, the court held that human recollection is not infallible, minor discrepancies are expected and may even signify honesty, and only grave unexplained contradictions or those affecting the substance of the case justify rejection of evidence. Both courts below had found the discrepancies minor.
Legality and appropriateness of the life sentence
Life imprisonment was lawful, mandatory and the only sentence permissible in law for defilement of a child aged eleven years or less; the victim's infancy and the appellant's lack of remorse made it proportionate.
Relying on the Supreme Court's decision in Republic v Mwangi; ISLA (Amicus Curiae), the court held that mandatory sentences under section 8 of the Sexual Offences Act remain lawful while that section is valid. The victim was nine months old, squarely within section 8(2), and any lesser punishment would derogate from the express command of Parliament and fail to vindicate the victim's rights.
Legal principles established
#- On a second appeal under section 361 of the Criminal Procedure Code, the Court of Appeal considers only matters of law and cannot interfere with findings of fact unless the courts below considered matters they ought not to have, failed to consider matters they should have, or were plainly wrong on the evidence as a whole.
- Not every contradiction in the prosecution case warrants rejection of evidence; only grave, unexplained contradictions or those pointing to deliberate untruthfulness or affecting the substance of the case do.
- So long as section 8 of the Sexual Offences Act remains valid, the mandatory sentences therein, including life imprisonment for defilement of a child aged eleven years or less, remain lawful.

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.
By dint of the provision of section 361 of the Criminal Procedure Code, we are enjoined to consider only matters of law.
grave contradictions unless satisfactorily explained will usually but not necessarily lead to the evidence of a witness being rejected.
some inconsistency in evidence may signify veracity and honesty, just as unusual uniformity may signal fabrication and couching.
so long as section 8 of the Sexual Offences Act remains valid, the mandatory sentences therein remain lawful.
In the result, we are satisfied that the appeal lacks merit and is hereby dismissed in its entirety.
