The bottom line
#Kenya's Court of Appeal upheld a life sentence for defilement, confirming mandatory minimum sentences and limiting second appeals to questions of law.
What this practically means
#Executive summary
#Key legal issues
#Scope of second appellate jurisdiction
The Court's jurisdiction is confined to matters of law; it may interfere with concurrent factual findings only where no evidence supports them or they rest on misapprehension or perverted construction of the evidence.
Section 361 of the Criminal Procedure Code delineates the second appeal jurisdiction to issues of law. The court adopted the Karani v R formulation, allowing interference with findings of fact only in extreme circumstances. Here the trial court and High Court made concurrent findings supported by the complainant's testimony, medical evidence and corroborating witnesses, so there was no basis for interference.
New grounds raised for the first time on second appeal
A ground not canvassed in the court below will generally not be entertained; here the complaint about the complainant being stepped down and not declared a vulnerable witness failed on the record, as she was recalled and cross-examined.
The court noted the vulnerable-witness ground was raised for the first time before it and was absent from the High Court grounds. Even so, the record showed the prosecution merely sought to step down the distressed minor so she could compose herself; she was later recalled and gave coherent testimony with full opportunity for cross-examination, so no prejudice arose.
Proof of penetration by medical evidence
Medical evidence of lacerations to the labia majora and minora with a freshly broken hymen, coupled with the complainant's testimony, constitutes sufficient evidence of penetration.
The clinical officer's findings showed recent genital injuries consistent with defilement, and the complainant's own account of the appellant's actions corroborated penetration. The appellant's contention that lacerations and a broken hymen did not conclusively establish penetration was rejected as without merit.
Failure to call a crucial witness (S)
The prosecution need not call every mentioned witness; only sufficient witnesses to prove the case beyond reasonable doubt. S, being the appellant's spouse, was competent but not compellable under Section 127(3)(b) of the Evidence Act, and her absence created no gap in the case.
Section 143 of the Evidence Act removes any numerical requirement of witnesses. Keter v Republic establishes that only sufficient witnesses need be called, judged by relevance and reliability. The prosecution attempted to locate S, who had absconded; her potential testimony was rendered non-essential by the overwhelming evidence of the complainant, her mother, the village elder and the clinical officer.
Lawfulness of the life imprisonment sentence
The life sentence is prescribed by Section 8(1) as read with Section 8(2) of the Sexual Offences Act; following the Supreme Court's decision in Republic v Joshua Gichuki Mwangi, courts have no discretion to go below statutory minimum sentences for sexual offences.
The court applied the Supreme Court's recent affirmation of the constitutionality of mandatory minimum sentences for sexual offences, holding that Parliament, not the Judiciary, sets sentencing parameters unless unconstitutional. The sentence, imposed by the trial court and upheld by the High Court, was lawful and not excessive.
Legal principles established
#- On a second appeal under Section 361 of the Criminal Procedure Code, the Court of Appeal entertains only issues of law, and may interfere with findings of fact only where they are not based on any evidence at all, or on a misapprehension or perverted construction of the evidence.
- The prosecution is not obliged to call every potential or mentioned witness; only such witnesses as are sufficient to prove the case beyond reasonable doubt, per Section 143 of the Evidence Act.
- A spouse is not a compellable witness against their partner in criminal proceedings under Section 127(3)(b) of the Evidence Act, and their absence does not of itself create gaps in the prosecution's case.
- Trial courts have no discretion to impose sentences below the statutory minimum for sexual offences; it is Parliament that sets sentencing parameters.
