MKN v Republic
The bottom line
#Kenya's Court of Appeal upheld a father's life sentence for incest, confirming that medical evidence alone need not prove penetration if testimony is credible.
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 ingredients of the offence of incest (relationship, penetration, identity of perpetrator) were proved to the required standard
- 2.Whether the complainant's evidence required corroboration and whether the medical evidence established penetration by the appellant
- 3.Whether the appellant's defence was properly dismissed by the courts below
- 4.Whether the mandatory minimum sentence of life imprisonment was unconstitutional and whether the sentence could be challenged on second appeal
Key legal issues
#Proof of penetration and identity of the perpetrator
Penetration and identity were proved to the required standard despite medical evidence that the complainant's genitalia appeared normal; epithelial cells in the urine indicated recent trauma consistent with penetration.
The court held that although the medical report could not establish the recency of the absence of the hymen, the presence of epithelial cells indicating trauma showed penetration had most likely recently occurred. The complainant's testimony was believed, the wife's alibi evidence was discredited (2nd October 2011 was a Sunday, not a school day), and the defence that a former landlord was the culprit was implausible. Concurrent findings below on identity bound the court.
Legality of the mandatory life sentence
The challenge to the mandatory life sentence failed because the sentence was not appealed before the High Court and was raised only as an afterthought; in any event the court affirmed the sentence as lawful.
The court reviewed the grounds of appeal in the High Court and found no sentence ground was raised there, precluding the Judge from addressing it. The issue surfaced only in submissions before the Court of Appeal as an afterthought. The court nonetheless affirmed the sentence as lawful, without engaging with the Machakos and Mombasa High Court decisions on mandatory minimum sentences cited by the appellant.
Treatment of concurrent findings of fact on second appeal
The court declined to depart from concurrent findings by the two courts below on the identity of the perpetrator.
Consistent with its limited jurisdiction on matters of law, the court found no basis to disturb the concurrent findings that the appellant, the complainant's father, was the perpetrator. It found no reason for the complainant to frame the appellant and described his defence as inconsistent and incredulous.
Legal principles established
#- On a second appeal, the Court of Appeal's jurisdiction is confined to matters of law and will not interfere with findings of fact by the two lower courts unless there is a misdirection or findings are unsupported by evidence.
- The key ingredients of the offence of incest that the prosecution must prove are the relationship of the accused to the victim, penetration, and that the accused was the perpetrator.
- A sentence not appealed before the first appellate court cannot be raised for the first time on second appeal as an afterthought.
Court orders

- 2.The conviction and sentence of life imprisonment imposed by the trial court and upheld by the High Court stand

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.
Our jurisdiction is limited to dealing only with matters of law but not issues of fact that the two courts below may have made findings upon unless it is demonstrated to our satisfaction that there has been a misdirection in the evaluation of facts
The key ingredients of the offence of incest which the prosecution must prove are: the relationship of the accused to the victim, penetration, and, that the appellant was the perpetrator of the offence
In the result, we find no merit in the appellant's appeal. The same is dismissed in its entirety.
