Paul & another v Republic (Criminal Appeal E291 of 2022) [2026] KECA 1162 (KLR)
The bottom line
#Kenya's Court of Appeal freed two men convicted of murder because forensic gaps and a missing key witness left the prosecution's case unproven beyond reasonable doubt.
What this practically means
#Executive summary
#Key legal issues
#Whether the cause of death was established and linked to the appellants beyond reasonable doubt
The Court found the prosecution failed to establish the cause of death and link it to the appellants: the organophosphate pesticide in the syringe was scientifically absent from the deceased's internal tissues and no forensic evidence bridged that gap.
PW1's postmortem gave only a suspected cause of death (ingestion of poisonous substances). PW5's analysis found no poisonous substance in the intestines, liver and lungs, while the syringe contained organophosphate pesticide fatal only if ingested. No forensic evidence explained how the substance could have been ingested yet be scientifically absent from the sampled tissues, so the link to the appellants was not proved beyond reasonable doubt.
Failure to charge or call Lucas Odhiambo, identified by the investigating officer as the main culprit
The adverse inference in Bukenya v Uganda applies: the unexplained failure to charge or call Lucas, whom PW7 called the main culprit, left an enormous gap in the prosecution's proof of guilt.
PW7 conceded in cross-examination that Lucas, the insurance beneficiary, was the main culprit yet was neither arrested nor called. Applying the three Bukenya rules, and giving no valid explanation, the Court drew the adverse inference that Lucas' testimony would have been adverse to the prosecution, compounding the contradictions among prosecution witnesses and defeating proof beyond reasonable doubt.
Identification of which appellant administered the substance
The conflicting testimony of PW3, PW4 and PW7 meant the prosecution failed to cogently show which of the two appellants administered the substance in the syringe.
PW3's evidence on cross-examination attributed the act to the 2nd appellant while her examination-in-chief referred to the 1st; PW4 was not definitive on which appellant was the suspect he found being beaten; PW7 said it was the 1st appellant. The Court, re-evaluating this conflicting evidence on a first appeal, held it could not be trusted and scattered the prosecution's case.
Malice aforethought and joint liability
With the appellants not linked to the cause of death, malice aforethought and any common intention under Section 21 of the Penal Code could not be established.
Since the prosecution failed to prove the unlawful act causing death, the element of malice aforethought necessarily collapsed; there was no evidence, individual or joint, of intention to cause death or grievous harm. The respondent's reliance on Section 206(a) of the Penal Code was rejected as unsupported by the record.
Duty of the first appellate court
As a first appellate court, the Court was bound to re-evaluate, re-assess and re-analyse the entire evidence and reach its own conclusions, making allowance for the trial court's advantage of seeing and hearing the witnesses (Okeno v Republic).
The Court restated the classic Okeno framework: an appellant on a first appeal is entitled to a fresh and exhaustive examination of the evidence and to the appellate court's own decision on it; the first appellate court must weigh conflicting evidence and draw its own conclusions, not merely scrutinise for some supporting evidence.
Legal principles established
#- Proof of death alone is insufficient to sustain a murder conviction; the prosecution must establish the cause of death and link it to the unlawful act or omission of the accused beyond reasonable doubt.
- Where the prosecution fails, without valid explanation, to charge or call a material witness or main culprit, the court is entitled to draw an adverse inference that their evidence would have been unfavourable to the prosecution.
Court orders
#- 1.Both appellants' convictions for the offence of murder are quashed
- 2.The sentence of death imposed against each appellant is set aside
- 3.Each appellant is set at liberty forthwith unless otherwise lawfully held
- On appeal from
- High Court of Kenya (trial court, Homa Bay; murder trial)
- Jurisdiction invoked
- First appellate jurisdiction of the Court of Appeal over conviction and sentence on a charge of murder under the Penal Code (Sections 203 and 204 as read with Section 204)
