Musyoka v Republic (Criminal Appeal 72 of 2019) [2025] KECA 51 (KLR)
The bottom line
#Kenya's Court of Appeal upheld a police officer's manslaughter conviction and 10-year sentence, ruling that excessive force during an arrest has no legal justification.
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 learned Judge's summoning of Benson Bufuke Opicho as a court witness violated the appellant's right to a fair trial under Article 50 of the Constitution
- 2.Whether the death of the deceased was proved
- 3.Whether the death of the deceased was caused by the actions or omissions of the appellant
- 4.Whether the acts causing death were unlawful or without lawful justification, and thus whether the ingredients of manslaughter were established beyond reasonable doubt
- 5.Whether the sentence of ten years imprisonment was appropriate
Key legal issues
#Power of a trial court to summon its own witness versus the accused's right to a fair trial
The summoning of Benson Bufuke Opicho under section 150 of the Criminal Procedure Code did not violate Article 50; the defence cross-examined the witness and declined an opportunity to seek an adjournment.
Section 150 confers a discretion, and a mandatory duty where the evidence is essential to a just decision, as held in Kulukana Otim v R on the in pari materia Ugandan provision. The power must be used judiciously and cannot convert the court into an investigatory agency. Here the witness was summoned as likely to give relevant evidence, was cross-examined at length by both sides, and the defence chose not to seek an adjournment. Relationship to the deceased does not disqualify a witness.
Causation of death - whether the appellant's assault caused the fatal intra-cranial pressure
The evidence, taken in its totality, established that the deceased's death resulted from blunt force trauma to the head inflicted by the appellant at arrest and in the police vehicle.
Eyewitnesses (PW4, PW5 and court witness Benson) saw the appellant strike the deceased; the deceased's complaints of severe headache at Sirisia and Malakisi stations, confirmed even by defence witnesses, corroborated continued assault in the vehicle; dying declarations to the wife and Benson were admissible under section 33(a) of the Evidence Act; and the appellant led no evidence that embalming compromised the autopsy or otherwise impugned the cause of death.
Lawfulness of the force used - whether the assault was a reasonable use of force in effecting arrest
There was no lawful justification for the force used; the appellant continued assaulting the deceased long after he had been arrested and subdued.
The appellant argued the violence was reasonable force in arresting an armed and dangerous person, but the trial Judge found the deceased was not armed and the beating unnecessary. The continuation of the assault in the police vehicle defeated any claim of lawful justification. The Court noted the appellant was fortunate not to have been convicted of murder, since continued blows to the head could satisfy malice aforethought under section 206 of the Penal Code, but the DPP did not cross-appeal.
Elements of manslaughter
All three elements of manslaughter - death, causation by the accused, and unlawfulness - were proved beyond reasonable doubt.
The Court defined manslaughter under section 202 of the Penal Code as unlawful killing without malice aforethought, requiring proof of death, a clear causal link between the accused's act or omission and the death, and unlawfulness excluding lawful justification such as self-defence. Each element was satisfied on the evidence, sustaining the conviction for the lesser cognate offence of manslaughter.
Legal principles established
#- A first appellate court must conduct a de novo review, re-evaluating the evidence as a whole and drawing its own conclusions, while making allowance for the trial court's advantage of seeing and hearing the witnesses.
- Under section 150 of the Criminal Procedure Code, a trial court has the power, and where evidence is essential a mandatory duty, to summon or recall witnesses at any stage of a trial, provided the power is exercised judiciously and consistently with Article 50 fair-trial rights.
- There is no rule that a relative or close business associate of a victim cannot testify in a criminal case; the safeguard is the accused's opportunity to cross-examine and impeach such evidence.
- Speculative hypotheses as to alternative causes of death not raised as evidence at trial cannot be introduced through submissions at the appellate level to found reasonable doubt.
Court orders
#- 1.The appeal against conviction is dismissed
- 2.The sentence of ten (10) years imprisonment is not interfered with
- 3.The appeal is dismissed in its entirety
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- High Court of Kenya at Bungoma
- Not stated in the judgment
- Jurisdiction invoked
- First appeal to the Court of Appeal against conviction and sentence (Criminal appeal; specific constitutional/statutory provision not stated in the judgment)
Relief refused
#Reversal of conviction on the ground that summoning a court witness violated the right to fair trial
The appellant had full opportunity to cross-examine the witness and could have sought an adjournment; no Article 50 violation established
Quashing of the conviction on the cause-of-death evidence
The speculative hypotheses about alternative causes of intra-cranial pressure were not introduced at trial and cannot be raised through submissions on appeal
Interference with the sentence of ten years imprisonment
The trial court explicitly considered mitigation and the sentence was eminently reasonable
Costs
No costs order stated in the judgment
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.
The upshot is that, in our view, all the elements of the offence of manslaughter were satisfied here. Consequently, the appeal against conviction is hereby dismissed.
We found no ground specifically addressing the sentence. We, however, note that the appellant was sentenced to ten (10) years imprisonment. The court explicitly considered his mitigation in fashioning the sentence. We think the sentence is eminently reasonable in the circumstances. We will not interfere with it.
The result is that the appeal is dismissed in its entirety.
It is not the function of a first appellate court merely to scrutinize the evidence to see if there was some evidence to support the lower court's findings and conclusions; it must make its own findings and draw its own conclusions.
A court may, at any stage of a trial or other proceeding under this Code, summon or call any person as a witness, or examine any person in attendance, though not summoned as a witness
We agree with the learned Judge that there is on record no justification for the kind of force used on the deceased; and that this was no reasonable use of force at all.
Issues in the judgment
#The judgment describes the deceased as having died on 16/04/2016, but the particulars of the charge state the murder occurred on 28/03/2016; the text itself notes the alleged offence date and the date of death differ without reconciliation.
The judgment states the deceased died on 16/04/2016 'while undergoing treatment for head injuries', yet the charge particulars allege the murder was committed on 28/03/2016, creating an internal inconsistency in dates.
