Jane Chesigei Sang v Republic [2016] KECA 163 (KLR)
The bottom line
#Kenya's Court of Appeal freed a woman convicted of murder on thin circumstantial evidence, ruling that mental illness meant she could not be held criminally responsible.
What this practically means
#Executive summary
#Key legal issues
#Sufficiency of circumstantial evidence to prove the actus reus of murder
The circumstantial evidence did not form a complete chain; the failure to call Brian, who was with the appellant in the locked kitchen, weakened the prosecution case and left open other possibilities such as accident or a third party's involvement.
Nobody witnessed the events; the case rested wholly on the discovery of the burnt body in a locked kitchen with the appellant inside. Applying the Abanga three tests and the Teper/Musoke co-existing circumstances rule, the court found the chain incomplete. Section 143 permits the prosecution to call any number of witnesses, but omitting the minor who could have unravelled the events cast a doubt that could only be resolved in the appellant's favour.
Misapplication of the evidential burden under Section 111 of the Evidence Act
The trial judge misapprehended Section 111 by holding that the appellant's inability to recall events confirmed a rebuttable presumption that she killed the deceased.
The trial court treated the appellant's lack of recollection as confirming guilt rather than as a possible product of her mental illness. Had the judge properly considered the effect of the mental illness on her capacity to understand, recall and explain her actions, he would not have held her to have failed to discharge the evidentiary burden. The appellate court interfered with the finding of fact on that narrow basis.
Insanity under Section 12 of the Penal Code as a defence excluding mens rea
The appellant, who had a chronic, episodic history of mental illness, was incapable of forming the necessary mens rea and discharged the burden of proving insanity under Section 111(2)(c) of the Evidence Act.
Psychiatric evidence established that the appellant's condition was recurrent and chronic, with lucid intervals, and that she may act without knowing what she is doing. Her own testimony that she learned of the killing only while in prison supported incapacity. Having proved insanity, she fell within the exceptions, exemptions and qualifications in Section 111(1) entitling her to an acquittal.
Legal principles established
#- Where a case rests entirely on circumstantial evidence, the circumstances must be cogently and firmly established, must unerringly point to the guilt of the accused, and must form a complete chain excluding any conclusion other than the accused's guilt.
- Before a court draws an inference of guilt from circumstantial evidence, it must be satisfied there are no co-existing circumstances weakening or destroying that inference; failure to call a key available witness weakens the prosecution case and casts doubt on the accused's culpability.
- An accused who discharges the burden of proving insanity under Section 12 of the Penal Code read with Section 111(2)(c) of the Evidence Act brings herself within the exceptions entitling her to an acquittal.
- On a first appeal the Court of Appeal must re-evaluate, re-assess and re-examine the evidence and reach its own independent conclusion, while allowing for the trial court's advantage of seeing the witnesses' demeanour.
