Thomas Chengo Mwambire v Republic
The bottom line
#Kenya's Court of Appeal confirmed a 26-year murder sentence, ruling that delayed death months after an assault does not break criminal responsibility for the killing.
What this practically means
#Executive summary
#Key legal issues
#Whether the elements of murder were proved beyond reasonable doubt
The death, its cause, the accused's causation and malice aforethought were all proved; the conviction was proper
The evidence of PW2 and PW4 established that they directly witnessed the appellant assault the deceased. Medical evidence showed death from cerebral vascular hemorrhage consistent with the brain injury sustained in the assault. The sustained attack on the head indicated intention to cause grievous harm or death, satisfying malice aforethought.
Whether there was a break in the chain of causation (novus actus interveniens)
No intervening act broke the chain of causation; death within the one-year period under section 215 of the Penal Code was attributable to the appellant's assault
The deceased died six months after the assault from cerebral vascular hemorrhage consistent with the head injuries inflicted. Under section 213 of the Penal Code and the substantial cause test, an accused's act need not be the sole or immediate cause of death; medical treatment administered in good faith does not break the chain. Death occurred within a year and a day.
Whether the prosecution relied on circumstantial evidence
The evidence was direct, not circumstantial, because PW2 and PW4 saw the appellant assaulting the deceased
Despite the appellant's submission that no one saw the assault, PW2 and PW4 gave direct eyewitness evidence of the appellant beating the deceased. Their evidence was corroborated by medical proof of brain hemorrhage consistent with the injuries. The identification was by recognition, which is more reliable than identification of a stranger.
Whether the postmortem report was produced in violation of the Evidence Act
The report was properly produced under section 33 of the Evidence Act by a doctor familiar with the document after the maker's retirement, without objection
Section 33 permits production of expert evidence where the maker cannot be procured. PW7, from the same hospital and familiar with the document, applied to produce the postmortem report after Dr. Mathias retired. The application was made without objection from the appellant and the court allowed it; the appellant never specified how the law was contravened.
Whether the prosecution witnesses' evidence was contradictory
The evidence was clear, consistent and cogent; any minor flaws were curable under section 382 of the Criminal Procedure Code
An evaluation of each prosecution witness's testimony disclosed consistency and mutual corroboration. The contradictions and inconsistencies complained of were not disclosed by the grounds and submissions, and any minor flaws fell within curable provisions. Additionally, the qualification of the investigating officer was not raised at trial and was declined on appeal.
Legal principles established
#- On a first appeal, the Court of Appeal must re-evaluate and independently analyse the evidence and draw its own conclusions while recognizing it did not see or hear the witnesses firsthand
- The prosecution must prove beyond reasonable doubt the death of the deceased and its cause, that the accused caused the death, and malice aforethought
- The chain of causation is not broken unless the accused's act is no longer a substantial and operating cause of death; an intervening act must be so overwhelming as to make the initial wound merely part of the history
Court orders
