Michael Kemosi Onyancha & 2 others v Republic
The bottom line
#Kenya's Court of Appeal upheld three murder convictions and thirty-year sentences, confirming that shared group liability applies even without proof of who struck the fatal blow.

#Key legal issues
#Elements of murder
All three elements - death and its cause, an unlawful act attributable to the accused, and malice aforethought - were proved beyond reasonable doubt.
Death and cause were established by the postmortem attributing death to blunt force trauma from multiple head and abdominal injuries. Eyewitnesses placed the appellants at the scene attacking the deceased with pangas, sticks and stones in daylight. The coordinated pursuit and repeated blows to vulnerable parts of an unarmed fleeing victim permitted inference of malice aforethought under Section 206.
Identification/recognition of the assailants
The appellants were positively identified by recognition by multiple witnesses, which was reliable and properly upheld.
The incident occurred in daylight at about 6:30 p.m. within the appellants' compound. PW1 and other witnesses knew the appellants as relatives and members of their community; no identification was based on a fleeting glance. Recognition is more reliable than identification of strangers, though caution is still required per Turnbull.
Common intention under Section 21 of the Penal Code
All appellants were liable as principal offenders in furtherance of a common intention irrespective of who delivered the fatal blow.
The appellants raised a false alarm, mobilised a mob and jointly attacked the deceased with crude weapons. Section 21 renders all who share a common intention to pursue an unlawful purpose equally liable where death results; the trial court's finding of shared intent was sound.
Alibi defences raised late
The alibis, raised for the first time at the defence hearing, were properly rejected after being weighed against the totality of prosecution evidence.
Because the alibis were raised late, the prosecution was denied an opportunity to interrogate them. Even so, following Juma Mohamed Ganzi and Wang'ombe, an alibi must be measured against the whole of the prosecution case; the trial court did so and found the alibis uncorroborated and dislodged by direct and consistent eyewitness evidence.
Sentence
Thirty years' imprisonment was lawful and not manifestly excessive; the appellate court declined to interfere.
Following Muruatetu, murder sentences are discretionary and mitigation must be considered, but the trial court already took first-offender status and mitigation into account in imposing less than the maximum. Given the brutality and retaliatory nature of the attack, the sentence disclosed no error warranting interference.
Legal principles established
#- A first appellate court must conduct a fresh and exhaustive re-evaluation of the evidence and reach its own conclusions while making allowance for not having seen or heard the witnesses.
- Failure to prove any one of the three essential elements of murder is fatal to the prosecution's case.
- Recognition of a known assailant is generally more reliable than identification of a stranger, but courts must still exercise caution even in recognition cases.
- Where two or more persons form a common intention to pursue an unlawful purpose and death results, all are equally liable regardless of who delivered the fatal blow (Section 21, Penal Code).
- An appellate court will not interfere with a sentence unless it is manifestly excessive or the trial court acted on a wrong principle or wrong material.
- An alibi raised late in the proceedings must nevertheless be weighed against the totality of the prosecution evidence.
