George Kimani Wamai & another v Republic [2009] KECA 21 (KLR)
The bottom line
#Kenya's Court of Appeal quashed a robbery conviction because one shaky, uncorroborated eyewitness identification could not safely prove guilt beyond reasonable doubt.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the evidence of identification by the single identifying witness was reliable enough to sustain the conviction
- 2.Whether the failure to call critical witnesses (village elders and witnesses to the bicycle recovery) was fatal to the prosecution case
- 3.Whether the prosecution failed to discharge its burden of proof beyond reasonable doubt
- 4.Whether the appellants' defence of alibi was displaced by the prosecution case
Key legal issues
#Reliability of single-witness identification
The complainant's identification evidence was unreliable: he wavered on when he recorded his statement, admitted giving no description of his attackers, and the elders rather than the complainant did the identifying.
The complainant contradicted himself about whether his statement was recorded before or after arrest and confessed to telling an untrue story. He had given no description of the attackers to the police prior to arrest, and village elders, who were not present at the robbery, were the ones who identified the arrested persons. Nothing linked the appellants to the recovered bicycle. With an eight-day gap between robbery and arrest, the conviction rested on unsafe identification evidence.
Defence of alibi and burden of proof
An accused who raises an alibi assumes no burden of proving it; it suffices if it introduces a reasonable doubt. The alibi here was never displaced by the prosecution.
Following Kiarie v Republic, the court held that no cogent evidence placed the appellants at the scene eight days before their arrest. Given the weaknesses in the identification evidence, the alibi stood unrebutted and provided a reasonable defence that the appellants were not part of the robbery gang.
Failure to call critical witnesses
Although one identifying witness may suffice under Section 143 of the Evidence Act, weak identification evidence should have been reinforced by other witnesses such as the village elders and witnesses to the bicycle's recovery.
The court accepted that Section 143 permits reliance on a single witness, but where that evidence is extremely shaky, the failure to call the village elders who identified the arrested youths, and those who witnessed the bicycle recovery, deprived the court of evidence necessary to ascertain the truth, making the conviction unsafe.
Legal principles established
#- Evidence of identification by a single witness that is unsatisfactory, inconsistent and uncorroborated by prior description of the attackers cannot sustain a conviction.
- Shaky and unreliable evidence of identification cannot displace a reasonable defence of alibi.
- Where identification evidence is weak, failure to call witnesses who could have assisted the court to ascertain the truth is fatal to a conviction.

Quotable passages
#Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.
We accordingly allow the appeal, quash the conviction and set aside the sentence of death (now commuted by His Excellency the President following the recent general commutation of death sentences) and order that the appellants be forthwith released unless lawfully held.
In our view, the chances of any other innocent youth joining the group to play Kamari are high and the appellant’s presence is not necessarily compatible with their guilt in the circumstances.
All in all, we think the errors of law on the lower court’s finding on identification and alibi were such as to making the conviction of the appellants’ unsafe.
No particular number of witnesses shall in the absence of any provision of law to the contrary be required for proof of any fact
Issues in the judgment
#The judgment states the alibi defence related to '31st October, 2009' whereas the robbery particulars allege 31st July, 2001 - an apparent date error in the judgment.
The memorandum of appeal is titled a further supplementary memorandum raising ten grounds, but the judgment opens by describing the appellants as 'Elias Mwaura Wawai and George Kimani Wawai' while the cause title lists 'George Kimani Wamai' as first appellant - an inconsistent spelling of the surname Wamai/Wawai.
