Boniface Barasa v Republic
The bottom line
#Kenya's Court of Appeal upheld a murder conviction but replaced the death sentence with 25 years' imprisonment, confirming premeditation defeats a provocation defence.
What this practically means
#Executive summary
#Key legal issues
#Whether the defence of provocation applied
The defence fails where the evidence shows the attack occurred at the deceased's house and was premeditated; nothing deprived the appellant of self-control.
Although the appellant claimed he found his wife and the deceased naked on his matrimonial bed, the eyewitness evidence of PW1 and PW4 showed the attack occurred in the deceased's house. Following section 208(1) of the Penal Code, provocation requires a wrongful act likely to deprive an ordinary person of self-control. The trial judge's finding of premeditation was affirmed, and the first ground of appeal rejected.
Whether malice aforethought was established under section 206 of the Penal Code
Malice aforethought was established: the appellant armed himself with a machete and proceeded to the deceased's house with intent to assault, and the attack was premeditated.
Section 206(a) deems malice aforethought established by an intention to cause death or grievous harm. Arming oneself with a machete and proceeding to the victim's house evidences such intent. The court also held, applying Karani vs Republic, that non-recovery of the weapon does not weaken the prosecution case on malice aforethought.
Whether the medical evidence on cause of death was misapplied
The internal blunt trauma (gall bladder perforation causing chemical peritonitis) was a direct result of the appellant's assault; the ground failed.
The postmortem established death from chemical peritonitis secondary to gall bladder perforation due to blunt trauma. The P3 form showed abdominal bruising, and PW4 saw the appellant beating the deceased with blows and kicks even after police arrived. The court agreed with the respondent that the internal trauma was a direct result of the assault and dismissed the appeal against conviction.
Whether the death sentence should stand
The death sentence was set aside because the trial court, deciding before Muruatetu, treated section 204 as mandatory and did not exercise sentencing discretion; a 25-year term was substituted.
The trial court sentenced the appellant to death without considering the Supreme Court's decision in Francis Muruatetu & Another vs Republic, which declared the mandatory death sentence under section 204 unconstitutional. The judge therefore exercised no discretion. Considering the circumstances of the offence and the appellant's custody since November 2017, the Court of Appeal substituted imprisonment for 25 years from the date of arrest.
Legal principles established
#- A first appellate court has a legal duty to re-evaluate, re-analyse and reconsider the evidence tendered at trial and arrive at its own independent conclusion, while making due allowance for not having seen or heard the witnesses.
- Non-recovery of a murder weapon does not dilute or defeat proof of malice aforethought where the offence is otherwise proved.
- A killing arising from a premeditated, planned attack is not provoked; an accused who has time to seek redress cannot claim a sudden and temporary loss of self-control.
