Bonaya Tutu Ipu & 1 other v Republic
The bottom line
#Kenya's Court of Appeal reduced a murder conviction and death sentence to manslaughter with a 10-year term because the fatal assault was spontaneous and involved no weapon.
What this practically means
#Executive summary
#Key legal issues
#Whether malice aforethought was proved beyond reasonable doubt
It was not. The assault was on the spur of the moment, without weapons or premeditation, and there was no evidence of knowledge that the actions would probably cause death or grievous harm under section 206(b) of the Penal Code; the doubt benefited the appellants.
Malice aforethought, the mens rea for murder, is rarely proved directly and is normally inferred from surrounding circumstances: the weapon used, the part of the body injured, the injuries inflicted and the accused's subsequent conduct. Here the slapping and kicking occurred spontaneously on a drunken intruder at midnight; no weapon was used; the fatal ruptured spleen was consistent with a kick; and the appellants did not flee. The trial judge merely recited section 206 without considering these circumstances, so knowledge under section 206(b) could not be inferred and the benefit of the doubt accrued to the appellants.
Effect of the respondent's concession on the appeal
The concession did not bind the court or guarantee the appeal's success; the court was enjoined to reach its own independent conclusion on the evidence and the law.
Although the respondent conceded that the conviction should be for manslaughter rather than murder, the court held that a concession cannot lead to automatic success, and conversely opposition cannot invariably lead to dismissal. The decision turns on whether the first appellate court's conclusions are proper on the evidence on record and the law. The court therefore independently reviewed the evidence before determining whether the conviction for murder could stand.
Appropriate sentence upon substituted conviction for manslaughter
A sentence of ten years imprisonment for each appellant, effective from the date of the High Court judgment, was commensurate with the offence.
The maximum sentence for manslaughter under section 205 of the Penal Code is life imprisonment. Taking into account the manner and circumstances in which the offence was committed, and the fact that the appellants had been in custody since their arrest in September 2011, the court found ten years imprisonment commensurate, and set aside the death sentence accordingly.
Legal principles established
#- A respondent's concession of a criminal appeal does not bind the appellate court, which must independently evaluate the evidence and the law.
- Malice aforethought is determined on the peculiar facts of each case, considering the weapon used, the part of the body injured, the type of injuries and the accused's subsequent conduct; where no weapon is used and there is no premeditation, knowledge that death or grievous harm would probably result may not be inferred.
