Koech v Republic
The bottom line
#Kenya's Court of Appeal upheld a life sentence for defilement of an eight-year-old, confirming that second appeals only address legal errors, not facts.
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 concurrent findings of fact by the two courts below on age, penetration and identification disclosed any error of law
- 2.Whether the medical evidence sufficed to corroborate penetration notwithstanding that it did not identify the perpetrator
- 3.Whether the prosecution was obliged to call additional eyewitnesses
- 4.Whether the sentence of life imprisonment was lawful and open to challenge on second appeal
- 5.Whether the appellant's fair-trial rights under Articles 25, 49 and 50 of the Constitution were observed
Key legal issues
#Scope of the Court's jurisdiction on a second appeal
Jurisdiction is confined to matters of law; concurrent findings of fact are not disturbed absent an error of law.
Section 361(1) of the Criminal Procedure Code restricts second appeals to matters of law. Severity of sentence is a matter of fact. Concurrent findings stand unless the lower courts considered matters they should not have, omitted matters they should have considered, or were plainly wrong so that the error becomes one of law, following Chris Kasamba Karani and Kalameni.
Sufficiency of medical evidence on penetration
Medical evidence establishing penetration sufficiently corroborated the complainant's account; identification of the perpetrator by DNA is not required.
The clinical officer found a broken hymen and positive clinical evidence of penetration two days after the incident. Citing Maina v Republic, the court held the purpose of the medical examination is to establish penetration, not to identify the perpetrator unless DNA evidence or examination of the suspect is involved. The medical evidence therefore corroborated the complainant.
Identification of the perpetrator
Identification was airtight: the appellant was a known relative, caught in the act in broad daylight by PW3 and shortly after by PW1.
The appellant was a cousin of PW3 and known to the complainant. The assault occurred in broad daylight; PW3 found him strangling the complainant with his trousers lowered, and PW1 arrived to find him still at the scene. Both courts below correctly found no possibility of mistaken identity and that he was caught in flagrante delicto.
Failure to call crucial eyewitnesses
The contention failed; the prosecution need not call every conceivable witness.
PW1 and PW3 were eyewitnesses to the immediate aftermath and their evidence was consistent with the complainant's. The law requires only that the evidence called proves the charge beyond reasonable doubt; there is no duty to call every conceivable witness. The appellant's bare denial was properly rejected by both courts below.
Sentence of life imprisonment
Life imprisonment is the mandatory sentence under section 8(2) of the Sexual Offences Act for a child aged eleven years or less; severity is a matter of fact outside second-appeal jurisdiction.
The complainant was eight years old, so section 8(2) applied mandatorily. Under section 361(1)(b) of the Criminal Procedure Code, sentence severity is a matter of fact unless the sentence was enhanced by the High Court or the subordinate court lacked power to impose it; neither circumstance arose.
Fair-trial rights
The appellant's rights under Articles 25, 49 and 50 of the Constitution were observed.
The appellant was informed of the charge, given an opportunity to challenge the evidence, and presented his defence. Both courts below considered and properly rejected his bare denial, which did not displace the cogent and consistent prosecution evidence.
Legal principles established
#- On a second appeal under section 361(1) of the Criminal Procedure Code, the Court of Appeal may only entertain matters of law and will not disturb concurrent 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 so that the error becomes a matter of law.
- The purpose of a medical examination of the victim in a sexual offence case is primarily to establish whether penetration occurred; it is not required to identify the perpetrator unless DNA evidence or examination of the suspect is involved.
- The prosecution is not obliged to call every conceivable witness; it is sufficient that the evidence called proves the charge beyond reasonable doubt.
- Severity of sentence is a matter of fact over which the Court has no jurisdiction on second appeal, unless the sentence was enhanced by the High Court or the subordinate court lacked power to impose it.
