John Kamau Wangui v Republic
The bottom line
#The court confirmed the death sentence, ruling that police evidence and witness identification were strong enough to prove the crime.
What this practically means
#Executive summary
#Key legal issues
#Reliability of visual identification by a single eyewitness
The appellant was positively identified by PW1 given the favourable circumstances: security lights, 20 minutes of proximity, and the appellant's active role in the attack
The court weighed the prevailing conditions at the scene - lighting, duration of contact, and the appellant's first entry into the compound with the complainant - and found the identification positive, supported by PW1's cross-examination testimony and her identification of the appellant at the parade.
Defective charge under article 50(2)(b) and sections 134 and 137 of the Criminal Procedure Code
The charge should have been framed as robbery with violence contrary to section 296(2) as read with 295 of the Penal Code, but the defect was curable and did not prejudice the appellant
The court found the particulars sufficiently detailed to inform the appellant of the offence, satisfying article 50(2)(b) and the Criminal Procedure Code, so the mislabelling of the section was a curable defect.
Corroboration of police witness evidence
Police witness evidence is not inherently incredible and requires no corroboration by independent witnesses
The court held that any credible witness, police or civilian, can prove a fact in issue; even accomplice evidence can be acted on without corroboration under section 141 of the Evidence Act, and police witnesses are not accomplices.
Disclosure of informer identity
The informer's identity was privileged from disclosure because his evidence would not have shown the appellant's innocence
Relying on section 132 of the Evidence Act and Marks v Beyfus, the court held that disclosure is only required where necessary to show the innocence of the accused; here the informer, if an accomplice, could not have assisted the defence.
Proof of possession of firearm and ammunition
Possession was proved by the recovery of an AK 47 rifle loaded with 23 rounds from the appellant's one-roomed house, confirmed by ballistics examination
Police officers searched the appellant's room, recovered the rifle and ammunition beneath a sofa set, and a ballistics examiner confirmed they were a firearm and ammunition as defined under the Firearms Act.
