The bottom line
#Kenya's Court of Appeal upheld three mob-justice murder convictions but cut the sentences to 20 years each, confirming everyone in a group attack is personally liable.
What this practically means
#Executive summary
#Key legal issues
#Whether the ingredients of murder were proved
The court affirmed that the prosecution must prove death, unlawful act or omission causing death, that the accused committed the act, and malice aforethought; all were proved against each appellant.
The court adopted the four elements as set out in Anthony Ndegwa Ngari v Republic. Death and its cause were uncontested, as the deceased died from severe head injuries inflicted by a mob. Identification placed each appellant at the scene actively participating in the assault. The nature, location and severity of the injuries demonstrated malice aforethought, satisfying section 206 of the Penal Code.
Whether identification of the appellants was safe
Identification by recognition in broad daylight by village mates who observed the chase and assault was reliable and safe to act upon.
Applying the Turnbull guidelines, the court found the conditions favourable: broad daylight, prolonged observation rather than a fleeting glance, prior acquaintance, and consistent, unshaken testimony by PW1 and PW2 that was mutually corroborative. Recognition is ordinarily more reliable than identification of a stranger, per Anjononi v Republic.
Whether common intention and malice aforethought were established
The appellants, acting in concert in an unlawful assault in which death was a probable consequence, were deemed to have the common intention of committing murder; malice aforethought was inferred from the targeted head injuries inflicted with sharp objects.
The evidence showed all appellants participated in beating the deceased, pursuing an unlawful purpose of which death was a probable consequence, invoking section 21 of the Penal Code principles as considered in Ombati v Republic. Malice aforethought under section 206 was inferred from the severe deep multiple cut wounds to the head and fractured ribs, indicating an intention to cause grievous harm or eliminate the deceased, per Rex v Tubere s/o Ochen.
Whether the alibi defences were considered
The trial judge duly considered the alibi defences but rightly found they did not dislodge the strong prosecution evidence.
The appellants each claimed they were drawn to the scene by noise and found the deceased already lynched. The court found that the learned judge considered these defences and rejected them because the eyewitness evidence of PW1 and PW2 squarely and consistently placed the appellants at the scene actively participating in the assault, arriving at a safe conclusion.
Whether the sentences were manifestly excessive
The appellate court interfered with sentence, substituting twenty years' imprisonment computed from the date of conviction, taking into account mitigation and time already served.
While sentencing rests in the trial court's discretion and interference is circumscribed per Bernard Kimani Gacheru v Republic, the court considered the circumstances: the allegation that the deceased had set a house on fire, the injuries inflicted, the appellants' mitigation, and that they had already served six years. It found twenty years appropriate and substituted it for the sentences of 40 and 30 years.
Legal principles established
#- On a first appeal, the appellate court must re-evaluate the whole evidence and reach its own conclusions, while making allowance for the trial court's advantage of seeing and hearing the witnesses
- Under the doctrine of common intent, each participant in a mob or group assault is personally liable for the acts of the group even where the person who rendered the fatal blow is not ascertainable
- Recognition of an assailant is more reliable than identification of a stranger because it depends on personal knowledge of the assailant
- An appellate court will not easily interfere with sentence unless it is manifestly excessive, the trial court overlooked a material factor, took into account wrong material, or acted on a wrong principle
