WC v Republic (Criminal Appeal 78 of 2018) [2023] KECA 597 (KLR)
The bottom line
#Kenya's Court of Appeal confirmed that a person found 'guilty but insane' of murder is a patient needing care, not a prisoner serving a sentence.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether malice aforethought was proved against the appellant
- 2.Whether the appellant could be convicted of murder within the meaning of Section 203 of the Penal Code
- 3.Whether the special finding under Section 166 of the Criminal Procedure Code amounts to a sentence
Key legal issues
#Whether malice aforethought was proved against the appellant
Malice aforethought was not proved; the appellant suffered from schizophrenia which impaired his mental faculties, so he lacked the mens rea for murder
The Court found overwhelming evidence from prosecution witnesses, corroborated by medical evidence from PW7 and the psychiatrist, that the appellant suffered from schizophrenia. Under Section 11 of the Penal Code, soundness of mind is presumed until the contrary is proved, and here the contrary was conclusively shown. The trial Judge was therefore correct to find the appellant incapable of understanding what he was doing when he killed the deceased.
Whether the special finding of 'guilty but insane' under Section 166 of the Criminal Procedure Code is a conviction or a sentence
The special finding is neither a conviction nor a sentence; it is treated as an acquittal because an essential element of murder is absent
Relying on PIM v Republic, KCK v Republic and Felstead v Rex, the Court held that the word 'guilty' in Section 166(1) merely confirms that the accused did the act charged, without the mental state for murder. The M'Naghten Rule, codified in Section 12 of the Penal Code, excuses criminal responsibility where disease of the mind renders the accused incapable of understanding his acts. Insanity is an illness requiring treatment, not punishment; a person detained at the President's pleasure is a patient, not a prisoner.
Whether the appeal challenging the conviction and detention at the President's pleasure had merit
The appeal had no substance and was dismissed; the trial court's special finding was proper
Although the appellant argued that he should have been set at liberty since malice aforethought was not proved, the Court agreed with the trial Judge's finding that there was no malice aforethought and that the special finding under Section 166 was properly made. Since the special finding is not a conviction and detention at the President's pleasure is preventive rather than punitive, there was no basis to interfere with the decision below.
Legal principles established
#- A special finding under Section 166 of the Criminal Procedure Code is neither a conviction nor a sentence; it is in effect an acquittal, and detention at the President's pleasure is preventive detention of a patient, not punishment
- A conviction for murder under Section 203 of the Penal Code cannot stand where malice aforethought (mens rea) is absent; both actus reus and mens rea must be proved
Court orders
#- 1.The appeal is dismissed
- 2.Orders accordingly (no other orders made)
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- High Court of Kenya at Eldoret
- Not stated in the judgment
- Jurisdiction invoked
- First appellate appeal to the Court of Appeal against the High Court's special finding under section 166 of the Criminal Procedure Code (the judgment does not cite the specific appellate provision)
Relief refused
#The appellant's prayer to be found not guilty and set at liberty
The Court found the special finding of guilty but insane was proper, as malice aforethought was not proved but the act was committed; the special finding is neither a conviction nor a sentence and detention at the President's pleasure is preventive, not punitive
Costs
No costs order was 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 the end, we find no substance in the appeal and the said appeal is accordingly dismissed. Orders accordingly.
We therefore find that the special finding under Section 166 is neither a conviction nor a sentence.
The special finding is then treated as an acquittal because one essential element for the commission of the offence of murder contrary to section 203 is absent.
It is trite that an act constituting an offence of murder does not make a person guilty unless the mind is also guilty.
Section 11 of the Penal Code presumes every person to be of sound mind, and to have been of sound mind at any time which comes in question, until the contrary is proved.
