Mwanzia Mbithi v Republic
The bottom line
#Kenya's Court of Appeal upheld a robbery-with-violence conviction and death sentence, ruling that Muruatetu does not soften the mandatory death penalty for that offence.
What this practically means
#Executive summary
#Key legal issues
#Whether the first appellate court fulfilled its duty to re-evaluate the evidence
The High Court properly re-evaluated the evidence, addressed the identification evidence at length and reached the correct conclusion
The first appellate court is mandated to reconsider and re-evaluate the evidence, bearing in mind it did not see or hear the witnesses. The High Court dwelt at length on the identification evidence, noting the identification occurred in broad daylight at 9.00 a.m., the complainant never lost sight of the appellant, and the appellant was arrested immediately after the robbery. The court found the identification evidence sound and the concurrent findings correct.
Whether inconsistencies in the prosecution case fatally undermined it
The alleged inconsistencies (location of the attack, timing of the injury) were trifling and did not undermine the prosecution case
Citing Richard Munene and Kiarie, the court distinguished trifling divergences from fundamental inconsistencies. The discrepancy between Mfangano Street and Ronald Ngala Street and the possibility the injury predated the robbery were minor and did not create doubt on the core issues, so the conviction based on the evidence stood.
Whether the death sentence for robbery with violence is unconstitutional per Muruatetu
No; Muruatetu 1 applies only to murder, and per Muruatetu 2 challenges to the mandatory death penalty for other capital offences must be separately filed and argued
Section 296(2) of the Penal Code prescribes the death penalty for robbery with violence. The Supreme Court in Muruatetu 2 clarified that Muruatetu 1 cannot be directly applied to treason, robbery with violence, or attempted robbery with violence, so the Court of Appeal could not review the sentence on that basis.
Ingredients of robbery with violence under section 296(2)
Being armed with a dangerous weapon, being in company of one or more persons, or wounding/beating the victim are the elements distinguishing section 296(2) from section 295; the prosecution must plead which element applies
Relying on Odhiambo & Another v Republic, the court reiterated that the prosecution must choose and state which of the aggravating elements distinguishes the charge from simple robbery. This framing guided the assessment whether the charge was proved.
Legal principles established
#- On a second appeal, the Court of Appeal is confined to matters of law and will not disturb concurrent findings of fact unless the courts below misdirected themselves, considered irrelevant factors, failed to consider material evidence, or reached plainly wrong conclusions.
- Only substantial and fundamental inconsistencies in prosecution evidence, not trifling contradictions, justify overturning a conviction.
- Muruatetu 1 does not apply to the mandatory death sentence for robbery with violence; any constitutional challenge to the mandatory death penalty for other capital offences must be properly filed and argued before the High Court.
- A new issue, such as denial of legal representation, cannot be raised for the first time on a second appeal if it was not canvassed before the first appellate court.
