Silas Kaimagol Chepkwony v Republic [2000] KECA 84 (KLR)
The bottom line
#Kenya's Court of Appeal reduced a police officer's murder convictions to manslaughter because heavy intoxication meant he lacked the intent to kill.
What this practically means
#Executive summary
#Key legal issues
#Insanity as a defence to murder
The defence of insanity failed; the requisite degree of proof of insanity in the legal sense was not established.
The trial judge found against the defence submission on insanity and the Court of Appeal agreed. Although a psychiatrist testified that temporary insanity could be caused by alcohol and the appellant had a cousin with mental illness, the court held the legal threshold of proof of insanity was not met, so responsibility for the acts remained with the appellant.
Effect of intoxication on mens rea for murder
Under Section 13(4) of the Penal Code, intoxication is taken into account in determining whether the accused formed the necessary intention; on the evidence the appellant acted without malice aforethought, so murder was not made out.
The court noted the complete absence of any quarrel, motive or provocation, the aimless firing of rounds, and the significant blood alcohol content. These circumstances were compatible only with the defence of intoxication and led to the conclusion that the appellant acted entirely without malice aforethought, warranting substitution of manslaughter convictions.
Appropriate sentence on substituted manslaughter convictions
The court substituted convictions for manslaughter and imposed twelve years' imprisonment on each count, to run concurrently, expressing condemnation of the wanton killings.
Having found the killings were committed by a highly intoxicated appellant engaged in wanton and aimless gun shooting, the court considered a substantial custodial sentence necessary to express horror and disgust at the loss of three lives, while recognising that murder was not established.
Legal principles established
#- Intoxication under Section 13 of the Penal Code must be taken into account in determining whether the accused formed the intent necessary for murder, but it is not the only factor for consideration; where the evidence as a whole shows absence of malice aforethought, a murder conviction cannot stand.
- An appellate court may interfere where the trial judge's finding on malice aforethought is contrary to the weight of the evidence.
