Ben Simiyu Khwatenge v Republic
The bottom line
#Kenya's Court of Appeal upheld a murder conviction but ruled that the 25-year sentence must count the years the appellant spent in custody before sentencing.
What this practically means
#Executive summary
#Key legal issues
#Ingredients of murder
The prosecution must prove death, causation by an unlawful act of the accused, and malice aforethought; all three were established on the evidence.
The Court adopted the settled formulation that death occurred, was caused by an unlawful act, and that malice aforethought attended the act. The post mortem showed death by internal bleeding from a ruptured spleen caused by a blunt object; PW7 confirmed the deceased was not sick when he left home, and there was no evidence of any intervening factor between the assault and the deceased being found in the ditch.
Causation and the one-year-and-a-day rule
The death resulted from the appellant's assault; section 215 of the Penal Code was noted as to the temporal nexus between cause of death and death.
PW1 and PW2 gave unchallenged evidence of a severe assault by the appellant in which he kicked the deceased with boots and stepped on him after he fell. The deceased was shortly thereafter found lying in a ditch unable to speak. There was no evidence of any intervening factor between the assault and the time he was found, so the medical opinion accorded with the injuries inflicted.
Malice aforethought
Malice aforethought was established from the manner of the assault: the appellant wore boots, struck the helpless deceased with fists, and stepped on him after he fell, then fled instead of assisting.
Applying the Tubere s/o Ochen criteria — the manner of striking, the conduct of the accused in fleeing the scene, and the dangerous severity of the harm — the Court found the appellant either intended to kill or cause grievous harm. The deceased was a Good Samaritan attempting to separate a fight, yet was subjected to a violent, sustained attack and left unattended.
Alibi defence
The alibi was properly considered by the trial court and was dislodged by clear and uncontroverted evidence of recognition placing the appellant at the scene in broad daylight.
The trial judge expressly weighed the alibi against the prosecution evidence, noting PW1 and PW2 were known to the appellant, the incident occurred in broad daylight at the home of PW2, and conditions for positive recognition without possibility of error existed. The appellant did not call any witness and raised the defence late; the appellate court independently re-evaluated and agreed the defence was unmerited.
First appellate mandate
As a first appellate court, the Court of Appeal must undertake a fresh and exhaustive examination of the evidence and reach its own conclusions.
The Court invoked rule 31(1)(a) of its Rules and the classic authority of Okeno v Republic, re-evaluating the evidence afresh while giving allowance for the fact that it neither saw nor heard the witnesses. On that re-evaluation, it independently assessed identification, causation, malice aforethought and the alibi before confirming the conviction.
Sentencing — period in custody
The trial judge erred in not expressly factoring in the period spent in custody; the sentence is to run from 28th February 2017.
The proviso to section 333(2) of the Criminal Procedure Code mandates that a sentence take account of time spent in custody before sentence. Sentencing being an exercise of discretion, the material considered must be set out to avoid any impression of arbitrariness. Following Ahamad Abolfathi Mohammed, mere assertion that the period was considered is insufficient; the sentence must be reduced proportionately.
Legal principles established
#- Trial courts are under a legal imperative to factor the period spent in custody into the sentence and must state what and how the period has been taken into account; failing which the sentence is presumed not to have factored it in.
- Where section 333(2) of the Criminal Procedure Code was not complied with, a first appellate court should direct that the sentence run from the date of arrest or commencement of custody.
Court orders
#- 1.The sentence of 25 years' imprisonment is directed to run from 28th February 2017, the date the appellant was presented to court and taken into custody
- 2.Save for that clarification, the appeal is dismissed
- On appeal from
- High Court of Kenya, Bungoma
- Jurisdiction invoked
- First appellate jurisdiction under the Court of Appeal's powers as a first appellate court, exercising the mandate under rule 31(1)(a) of the Court's Rules
