Wesonga v Republic (Criminal Appeal 179 of 2020) [2023] KECA 1302 (KLR)
The bottom line
#Kenya's Court of Appeal freed a man serving 25 years because prosecutors failed to disprove his alibi — a defence an accused never has to prove.
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 appellant's alibi defence was properly interrogated by the prosecution
- 2.Whether the prosecution proved its case beyond reasonable doubt, including identification of the appellant
Key legal issues
#Whether the prosecution discharged its duty of disproving the appellant's alibi defence
The prosecution did not dislodge the alibi; the trial court's contrary conclusion was wrong.
The appellant raised the alibi at the earliest opportunity, stating he was in Belgut about 6-7 hours away, and named two colleagues whose statements supported it. The investigating officer's evidence did not confirm attendance on the material weekend, and the prosecution declined to call the two supporting witnesses, without any explanation that they were unavailable. The court held the alibi plausible and that its failure of disproof cast a reasonable doubt on identity, requiring acquittal.
The allocation of the burden of proof on an alibi defence
An alibi raises a specific defence carrying no burden on the accused; if it introduces a reasonable possibility of innocence, the prosecution has failed.
Relying on its own precedents, the court restated that a successful alibi entirely rules out the accused as the perpetrator; there is no burden of proof on the accused to prove an alibi; and if there is a reasonable possibility that the alibi could be true, the accused must receive the benefit of the doubt. Merely believing the prosecution's case does not amount to rejecting the alibi; the evidence must be weighed in its totality.
The role of a first appellate court
As a first appellate court, the Court of Appeal must analyse and re-evaluate the evidence afresh while mindful that the trial court saw and heard the witnesses.
The court invoked its settled mandate to subject the entire evidence to a fresh evaluation. Applying that mandate, it re-assessed the alibi evidence and the identification testimony, concluded that the trial court's evaluation was defective in respect of the alibi, and accordingly allowed the appeal and quashed the conviction and sentence.
Legal principles established
#- An accused who raises an alibi bears no burden of proving it; the law imposes on the prosecution the duty wholly to disprove it, and failure to do so injects the case with reasonable doubt.
- Where an alibi is supported by witness statements, the prosecution should call those witnesses; failure to do so permits the inference that their evidence would have been adverse to the prosecution case.
Court orders
#- 1.The appeal is allowed

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.
Accordingly, we allow the appeal, quash the conviction and set aside the sentence meted upon the appellant. The appellant be and is hereby set at liberty unless otherwise lawfully held.
An accused person who raises an alibi assumes no burden to prove it but the law imposes a duty on the prosecution to wholly disprove it.
That failure leaves the alibi as possibly true which in turn injects the prosecution case with the destructive germ of reasonable doubt.
No amount of suspicion no matter how strong can justify a conviction where a reasonable doubt of guilt lingers.
In order to convict there must be no reasonable doubt that the evidence implicating him is true
