Mwangi & another v Republic
The bottom line
#Kenya's Court of Appeal confirmed that constitutional violations during a criminal trial lead to damages, not automatic acquittal.
What this practically means
#Executive summary
#Key legal issues
#Scope of second appellate jurisdiction under section 361(1)(a) Criminal Procedure Code
The Court's mandate on second appeal is confined to matters of law; it must accept findings of fact of the lower courts unless no reasonable tribunal could have reached them.
The Court invoked section 361(1)(a) CPC and the Supreme Court's three-element characterisation of 'matters of law' in Munya. It applied the two-fold test: whether concurrent findings were based on no evidence or misapprehension of evidence, and whether the courts below acted on wrong principles. Finding the test unmet, it confined itself to points of law.
Effect of alleged constitutional violations (delay in charging and trial) on conviction
Even if the breaches occurred, they cannot be a basis for acquittal on appeal; the appellants must pursue independent remedies in the right forum.
The Court noted the appellants were at all material times serving a custodial sentence in another case, and that repeated disappearance of court files occasioned fresh trials. Relying on Julius Kamau Mbugua v Republic, it held that violation of the 24-hour production right does not automatically result in acquittal; damages is the remedy. The appeal could not stand on that ground.
Sufficiency of identification evidence and value of dock identification
The prolonged, uninterrupted daylight interaction between the witnesses and the appellants corroborated the parade and dock identifications; dock identification is not evidentially worthless if tested with care and duly warned of.
The first appellate court extensively re-evaluated the identification evidence as required by Okeno v Republic. The witnesses spent hours with the assailants in clear daylight with faces uncovered. Relying on Muiruri & 2 others v Republic, the Court held dock identification can sustain a conviction where the court warns itself of mistaken identification and is satisfied the evidence is true.
Proof of robbery with violence and number of witnesses
All ingredients of robbery with violence under section 296(2) were met and the case was proved beyond reasonable doubt; there is no legal requirement on the number of witnesses.
Relying on section 143 of the Evidence Act and Keter v Republic, the Court held the prosecution need only call sufficient witnesses to establish the charge. The evidence showed the appellants were armed, in company, and used violence. Proof of any one ingredient suffices (Oluoch v Republic), subject to curable flaws under section 382 CPC.
Alibi defences and alleged shift of burden of proof
The overwhelming evidence of positive identification defeated the alibis; the trial record disclosed no shift of the burden of proof, and the Judge's remarks on missing records were obiter dictum with no bearing on the conviction.
The conviction hinged almost entirely on identification by PW1, PW2, PW2B and PW3, who spent long hours under restraint with the appellants. The Court found the alibis could not stand against that evidence, and that the learned Judge's observations on the disappearance of records were inconsequential obiter, not findings shifting the burden of proof.
Legal principles established
#- On a second appeal, the Court of Appeal is confined to matters of law and will not interfere with concurrent findings of fact of the two lower courts unless based on no evidence, a misapprehension of evidence, or wrong principles.
- Violation of the right to be produced in court within twenty-four hours does not automatically result in acquittal; the remedy lies in damages in an independent proceeding.
- Dock identification is not inherently worthless; a court may base a conviction on it if satisfied it is true and after warning itself of the danger of mistaken identification.
- Proof of any one of the ingredients of robbery with violence is sufficient to sustain a conviction.
- The Constitution's supremacy provisions apply retrospectively; a Constitution is not subject to the same principles against retroactivity as ordinary legislation.
