Isaac Onyango Mugoma & another v Republic
The bottom line
#Kenya's Court of Appeal reduced two vigilante members' murder convictions to manslaughter because prosecutors couldn't prove the killers intended to cause death.
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 appellants were among the group which seized the deceased from his house, beat him and caused the injuries resulting in his death
- 2.Whether malice aforethought was proved to sustain a conviction for murder
Key legal issues
#Participation of the appellants in the killing
The appellants, together with other members of the vigilante group, seized the deceased, beat him and caused the fatal injuries; this was not challenged on appeal.
The evidence of the wife of the deceased and other victims established that the appellants were among the vigilantes who arrested and beat the deceased. Counsel for the appellants did not challenge this assertion in submissions, leaving the court with little difficulty in concluding participation was proved.
Proof of malice aforethought
Malice aforethought was not proved; the actual circumstances of the death were unknown, so murder could not stand.
The evidence as to what happened immediately before and at the moment of the killing was contradictory, resting on the testimony of the deceased's wife and other victims. The court held the prosecution had not discharged its burden of proving malice aforethought, rendering the murder conviction unsustainable.
Weight to be attached to assessors' opinions
Although a judge may disagree with assessors, their opinions are of great importance in assessing contradictory evidence.
Section 322(4) of the Criminal Procedure Code mandates trials with assessors in murder cases. The court observed that assessors may guide a court as to the truth of what witnesses said, particularly where evidence is contradictory, even though the judge retains the legal right to differ from their verdict.
Legal principles established
#- A trial judge is not bound to conform to the opinion of assessors and may lawfully disagree with their verdict.
- The prosecution bears the burden of proving malice aforethought; where that burden is not discharged, a murder conviction cannot stand.
- An appellate court may substitute a conviction for a lesser offence where the unlawful killing is established but malice aforethought is not proved.
Court orders
#- 1.Conviction of murder quashed
- 2.Conviction for manslaughter substituted
- 3.Each appellant sentenced to five (5) years imprisonment from the date of conviction
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- High Court of Kenya at Kisii
- HCCR Case No 20 of 2000
- Jurisdiction invoked
- First appellate jurisdiction over High Court conviction and sentence (Criminal Procedure Code appellate provisions)
Relief refused
#Outright acquittal of the appellants
Court was in no doubt the appellants caused the death unlawfully, so a manslaughter conviction was substituted rather than an acquittal
Costs
No costs order made 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.
In our view, the burden was on the prosecution to prove malice aforethought and that burden has not been discharged.
The learned judge, correctly so, was not bound to conform to the opinion of the assessors. He had a right under the law to disagree with them as he did.
It must follow, then, that as that burden has not been discharged the conviction of murder cannot stand. We quash it.
Each appellant is sentenced to five (5) years imprisonment from the date of conviction.
