Michael Kariuki Ng’ang’a v Republic
The bottom line
#Kenya's Court of Appeal upheld a life sentence for defilement, confirming it can only review legal errors, not facts, on second appeal.
What this practically means
#Executive summary
#Key legal issues
#Proof of defilement
The prosecution proved the three essential ingredients of defilement: penetration, the victim's age of 11 years or less, and the identity of the perpetrator.
PW1's testimony was detailed and consistent, corroborated by his physical condition observed by his mother, medical findings of anal trauma consistent with sodomy, and the chain of events including PW1 leading witnesses to the appellant's house where he was found. The complainant's mother's testimony on age was supported by an age assessment report placing the complainant below nine years. No error of law in the concurrent findings was demonstrated.
Identification of the perpetrator
Identification was positive and reliable based on adequate lighting, prolonged interaction, absence of facial concealment, and immediate identification at the appellant's residence.
The complainant encountered the appellant under security lighting, was held by him and remained in his candle-lit house throughout the night, affording ample opportunity to observe him. The appellant's face was not concealed, and the complainant promptly led his mother and PW3 to the appellant's house where he was found. Accordingly, the absence of an identification parade did not weaken the prosecution case.
Sufficiency of minor's testimony and corroboration
Under section 124 of the Evidence Act, a court may convict on the testimony of a minor in a sexual offence where satisfied of its credibility, here further corroborated by medical evidence.
Section 124 of the Evidence Act permits reliance on the testimony of a minor in sexual offences where the court is satisfied as to its credibility, with reasons recorded. The medical evidence by PW5 of traumatic anal injuries consistent with sodomy strongly corroborated penetration and provided independent support for PW1's testimony.
Alleged contradictions and the defence
The discrepancies were minor, did not go to the root of the charge, and the defence of denial and mob injustice did not rebut the prosecution's corroborated evidence.
Applying Phillip Nzaka Watu v Republic, some discrepancies in human recollection are expected and whether they render evidence unbelievable turns on the circumstances. Here the discrepancies were minor and did not go to the root of the charge. The defence consisted primarily of denial and allegation of mob injustice; no alibi was substantiated as the appellant was found at the location identified by PW1.
Sentence
No error of law in sentencing was shown; the life sentence stands, severity of sentence being a question of fact outside second-appeal remit.
Following Octavious Waweru Kibugi v Republic, which deferred to the Supreme Court's decision in Republic vs Mwangi (ISLA), the minimum mandatory sentences under the Sexual Offences Act remain lawful until the Supreme Court determines otherwise on proper escalation. Severity of sentence in a second appeal is a question of fact outside section 361(2) of the Criminal Procedure Code.
Legal principles established
#- On a second appeal, the Court of Appeal is confined to points of law and is bound by concurrent findings of fact of the lower courts unless those findings are shown to be based on no evidence.
- The Court of Appeal cannot interfere with concurrent findings of fact unless it is demonstrated that the courts below acted on no evidence, misapprehended the evidence, or applied wrong principles of law.
- Where identification is by a witness who had prolonged interaction with the perpetrator under adequate lighting, the absence of an identification parade does not weaken the prosecution case.
- In a second appeal, severity of sentence is a question of fact outside the Court's remit under section 361(2) of the Criminal Procedure Code, and the minimum mandatory sentences under the Sexual Offences Act remain lawful until determined otherwise by the Supreme Court.
