E N K v Republic
The bottom line
#Kenya's Court of Appeal replaced a mother's murder conviction and death sentence with a special finding that she killed her daughter while insane.
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 prosecution proved beyond reasonable doubt that the appellant murdered her daughter N
- 2.Whether the appellant was insane at the time she killed the deceased, the burden of proving insanity being on the accused on a balance of probabilities
- 3.Whether the learned trial judge was entitled to reject the uncontradicted expert psychiatric evidence of Dr Okonji on the grounds he gave
Key legal issues
#Duty of a first appellate court
The court applied its duty to re-evaluate the trial evidence and concluded the circumstantial evidence irresistibly pointed to the appellant as the killer.
Citing Okeno v Republic, the court reconsidered the evidence: the appellant received the deceased, gave false accounts of her whereabouts, was seen leaving with her carrying a panga, and was identified fleeing the dumping site with a blood-stained blouse and panga. The retracted inquiry statement was corroborated by this circumstantial evidence.
Insanity and burden of proof
Once the accused raises a reasonable probability of insanity, the prosecution must disprove it beyond reasonable doubt; the prosecution called no medical evidence and withheld the P3 Form.
The court held the trial judge's rejection of Dr Okonji's evidence rested on speculation about concealment and normal behaviour, matters on which the psychiatrist was never challenged. With no prosecution medical evidence and the P3 Form not produced, the prosecution failed to establish sanity beyond reasonable doubt.
Treatment of expert evidence
Following Dhalay, expert opinions must be considered with all other evidence and may be rejected only on proper and cogent grounds, with reasons given.
The court endorsed Parvin Singh Dhalay and Elizabeth Kamene Ndolo: courts must respect but are not bound by expert opinion. However, where a properly qualified expert gives reasoned, uncontradicted opinion evidence, there is no basis for rejection; the trial judge's reasons here were speculative.
Disposition under section 166 Criminal Procedure Code
On finding the act committed but the accused insane, the court substituted a special finding and ordered detention during the President's pleasure.
Rather than acquitting (as the third assessor urged) or convicting of manslaughter (as two assessors found), the court invoked section 166(1) to record a special finding of insanity and, under section 166(2), ordered detention in prison custody pending the pleasure of the President.
Legal principles established
#- A first appellate court must reconsider the evidence, evaluate it itself and draw its own conclusions.
- There is no presumption of insanity; the law presumes sanity and the accused bears the burden of proving insanity on a balance of probabilities, after which the prosecution must disprove it beyond reasonable doubt.
- Expert opinion is not binding on the court and may be rejected only for sound and cogent reasons; where uncontradicted qualified expert evidence stands, a court rejecting it on speculation errs.
- Where an accused raises a reasonable probability of mental illness at the time of the offence, the burden shifts to the prosecution to dislodge it beyond reasonable doubt.
Court orders
#- 1.Appeal allowed to the extent that the conviction for murder and the sentence of death are set aside
- 2.Substitution of a special finding under section 166(1) of the Criminal Procedure Code that the appellant committed the act of killing her daughter N but was insane at the time
- 3.Pursuant to section 166(2) of the Criminal Procedure Code, the appellant to be detained in prison custody pending the pleasure of His Excellency the President
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- High Court of Kenya at Nairobi
- Jurisdiction invoked
- First appellate jurisdiction over a High Court murder conviction; appeal disposed of under section 166(1) of the Criminal Procedure Code
Relief refused
#Outright acquittal as urged by the third assessor's verdict
The court disagreed that insanity meant no offence; the proper disposition was a special finding under section 166(1) of the Criminal Procedure Code, not an acquittal
Conviction for manslaughter as found by two assessors
The court found the appellant insane at the time of the killing, which excluded both murder and manslaughter verdicts
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.
We accordingly allow the appeal to the extent that we set aside the conviction for murder and the sentence of death and substitute the conviction with a special finding under the above stated section to the effect that the appellant committed the act of killing her daughter N but that at the time she killed N, the appellant was insane.
Pursuant to section 166 (2), we order that the appellant shall be detained in prison custody pending the pleasure of His Excellency the President.
there cannot be a presumption of insanity; on the contrary the law assumes that every person is sane and intends the natural and probable consequences of his or her actions until the contrary is proved.
The burden then shifted to the prosecution to dislodge, and do so beyond any reasonable doubt, that the appellant was infact sane when she killed Nancy.
We repeat that the judge was entitled to reject such evidence but only for sound and cogent reasons.
