Abdalla Omar Mwangeshi v Republic [2019] KECA 648 (KLR)
The bottom line
#Kenya's Court of Appeal reduced a murder conviction to manslaughter because drunkenness meant the attacker could not have intended to kill.
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 caused the death of the deceased
- 2.Whether the killing was with malice aforethought, including whether the defence of intoxication could negative the intent to kill
Key legal issues
#Whether the evidence proved that the appellant caused the deceased's death
Yes. Though circumstantial, the chain of evidence was unbroken and excluded any other possible killer.
No witness saw the stabbing, so the case rested on circumstantial evidence. PW1 saw the appellant chasing and pushing the deceased; PW4 heard threats and the killing; PW5 heard cries for the appellant to be held. No one else was present, had reason, or opportunity to kill the deceased. The chain was complete and pointed irresistibly to the appellant, satisfying the Koskei/Musoke and Ochieng’ tests.
Whether the defences of self-defence and intoxication were available
Self-defence failed because the retaliatory force was excessive; intoxication, though not raising insanity, negatived malice aforethought.
The Court did not believe the deceased attacked the appellant, and even if he had, the force used was excessive, negating self-defence. On intoxication, the trial judge wrongly treated it solely as a plea of insanity, imposing an onus on the appellant; properly, intoxication was raised merely to negative intent, requiring no onus, and reduced murder to manslaughter.
Whether the trial judge properly considered the defence of intoxication on malice aforethought
No; the judge dealt with it in too narrow a scope, and malice aforethought was not proved beyond reasonable doubt.
The judge considered intoxication only as a defence pleading temporary insanity under section 13 of the Penal Code, overlooking that intoxication can also be pleaded to negative the intent to kill, where the strictures of section 13 are loosened and no onus rests on the accused. Applying Maina and Manyara, the Court found the appellant incapable of forming an intent to kill and substituted manslaughter.
Legal principles established
#- On a first appeal, the appellate court must re-examine the evidence afresh and reach its own conclusions, making allowance for the trial court's advantage of seeing the witnesses.
- A conviction on circumstantial evidence requires circumstances that point irresistibly to the accused to the exclusion of all others.
- Where intoxication is pleaded merely to negative the intent to kill, the accused bears no onus of proof; it is a misdirection to place that onus on the accused.
Court orders
#- 1.Conviction for murder set aside and substituted with a conviction for manslaughter contrary to section 202 as read with section 205 of the Penal Code
- 2.Sentenced to a prison term of 20 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 Mombasa
- H.C.CR.C 29 of 2012
- Jurisdiction invoked
- First appeal to the Court of Appeal under the Criminal Procedure Code/Constitution (as a first appellate court exercising full re-evaluation jurisdiction; specific provision not stated in the judgment)
Relief refused
#Complete acquittal on the murder charge
The Court was satisfied beyond reasonable doubt that the appellant killed the deceased; only malice aforethought was negatived by intoxication
Credit for time spent in custody
Counsel urged the Court to consider time in custody, but no such order was made; the sentence was fixed at 20 years from the date of conviction
Costs
No costs order was made (criminal appeal; none recorded 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.
An appellant on a first appeal is entitled to expect the evidence as a whole to be submitted to a fresh and exhaustive examination
in order for a conviction to be founded on such evidence, it must point irresistibly to the accused person to the exclusion of any other person
if the plea is merely that the accused was by reason of intoxication incapable of forming the specific intention required to constitute the offence charged, it is a misdirection if the trial court lays the onus of establishing this upon the accused.
It is of course correct that if the accused seeks to set up a defence of insanity by reason of intoxication, the burden of establishing that defence rests upon him in that he must at least demonstrate the probability of what he seeks to prove.
It was the duty of the Judge to deal with alternative defences, such as intoxication, that emerged from the evidence, which might reduce the charge to manslaughter.
the charge of murder was not proved to the required standard, with the result that the conviction for murder is hereby set aside and in its place we substitute therefor a conviction for the charge of Manslaughter contrary to section 202 as read with section 205 of the Penal Code.
the sentence that commends itself to us is a prison term of 20 years imprisonment from the date of conviction.
