Samwel Mwera Mugini & 1 other v Republic
The bottom line
#Kenya's Court of Appeal confirmed that strong circumstantial evidence can convict, and death sentences for robbery with violence remain valid despite the Muruatetu ruling.
What this practically means
#Executive summary
#Key legal issues
#Sufficiency of circumstantial evidence
The threads of circumstantial evidence - the armed raid, the firefight with Tanzanian police, recovery of an AK47 and cattle, the appellants found with fresh gunshot wounds near the scene, and the falsity of the wedding explanation - formed a complete chain pointing unerringly to guilt.
The court applied the settled tests that inculpatory circumstances must be cogently established, be of a definite tendency, exclude every hypothesis except guilt, and form a chain so complete as to leave no reasonable ground consistent with innocence. The false alibi, unexplained gunshot wounds, arrest about 1km from the scene, failure to report the alleged arrow attack or seek treatment, and the recovered stolen cattle collectively excluded innocence. The call to modernise the doctrine with DNA or gun-residue testing was rejected as belated and unparticularised.
Alibi defence
Although the burden of disproving an alibi lies on the prosecution, this alibi was raised too late, was not investigated in time, and was displaced by the prosecution's strong evidence.
The court restated that the prosecution bears the burden of disproving an alibi once raised, but noted the defence emerged only in the appellant's sworn statement, depriving investigators of the chance to test it. The alleged wedding was found not to have taken place, the clinical officer confirmed the wounds were gunshot not arrow injuries, and the appellant was arrested in the vicinity of the crime. The concurrent findings of the two lower courts were therefore not disturbed.
Failure to call crucial witnesses
The prosecution was under no duty to call the house owner or the informer because their evidence was not crucial; failure to call them did not materially affect the case.
Section 134 of the Evidence Act provides that no particular number of witnesses is required to prove any fact. Adverse inference may arise only where a witness who could have given material evidence is withheld. Here it was common ground that the appellant was arrested in the house in the owner's absence, so the owner's evidence would have been superfluous; likewise the informer's evidence would not have assisted either side. The prosecution case stood on the evidence actually adduced.
Constitutionality of the death sentence for robbery with violence
The Muruatetu 1 dictum applies only to murder; a constitutional challenge to the mandatory death penalty for robbery with violence must be mounted before the High Court, and cannot be raised for the first time on second appeal.
Article 26(3) permits the death penalty for lawful convictions of capital offences. Muruatetu 1 invalidated only the mandatory death sentence under section 204 of the Penal Code for murder; Muruatetu 2 clarified it did not extend to other capital offences, directing that such challenges be fully argued in the High Court and escalated if necessary. The appellant was convicted under section 296(2) and had not raised the constitutional question in the High Court, so this Court was precluded from entertaining it.
Legal principles established
#- On a second appeal, the Court of Appeal's jurisdiction is confined to matters of law only and it will not disturb concurrent findings of fact unless unsupported by evidence or based on misdirection or errors of law.
- Circumstantial evidence sustained as a complete chain that excludes every other reasonable hypothesis is sufficient to convict; the doctrine remains good law and is not to be refashioned merely because of advances in technology absent a properly raised argument.
- The burden of disproving an alibi lies on the prosecution once raised, but an alibi raised late in the proceedings may be weighed against the accused and does not displace strong prosecution evidence.
- The prosecution is not obliged to call a multiplicity of witnesses; failure to call a witness is only material where the witness could have given crucial evidence, failing which the prosecution case is not weakened.
- The Muruatetu 1 declaration on the mandatory death sentence applies only to murder; a challenge to the mandatory death penalty for other capital offences such as robbery with violence must be mounted and fully argued before the High Court and escalated if necessary, and cannot be raised for the first time in the Court of Appeal.
