Wario v Republic (Criminal Appeal 159 of 2014) [2015] KECA 521 (KLR)
The bottom line
#Kenya's Court of Appeal confirmed a murder conviction, ruling that being drunk, claiming provocation, or self-defence cannot excuse a fatal stabbing.
What this practically means
#Executive summary
#Key legal issues
#First appellate duty
The Court re-evaluated the evidence itself and concluded the conviction was sound.
Relying on Okeno v R, the Court undertook its own analysis of the evidence, weighing the testimony of PW4 and PW5, the post-mortem findings and the appellant's unsworn statement, before agreeing with the High Court's findings on actus reus and mens rea.
Intoxication as a defence to murder
The defence failed; the evidence showed the appellant was not so drunk as to be incapable of forming intent, and his detailed recollection and flight belied the plea.
Section 13 of the Penal Code permits intoxication as a defence only in narrow circumstances. Where the plea is insanity by reason of intoxication, the burden rests on the accused; where it is incapacity to form intent, the prosecution must disprove it. Here PW4 and PW5 testified the appellant was not incapacitated, he wrestled with several people, recalled events in detail and fled, from which intention to cause grievous harm could be inferred.
Provocation
Provocation failed; the degree of retaliation with a knife was disproportionate to any lawful act of ejection from the pub.
The evidence of PW1, PW4 and PW5 showed the deceased, with the watchman's help, merely asked the appellant to leave the premises. Their testimony did not support the appellant's claim of physical and verbal abuse. Applying Tei s/o Kabaya v R, the lethal nature of the weapon and degree of retaliation were inconsistent with heat of passion reducing murder to manslaughter.
Self-defence
The defence failed as there was no evidence that the appellant faced any danger causing him to fear for his life.
Under section 17 of the Penal Code, criminal responsibility for force used in self-defence is determined by English common law principles, which require an honest and reasonable belief in an imminent attack (DPP v Morgan). The record disclosed no such danger; the appellant was the aggressor who stabbed the deceased.
Accomplice evidence and common intention
PW4 and PW5 were not accomplices; no common intention under section 21 of the Penal Code was established and they disassociated themselves from the assault.
The trial judge found no common intention. PW4 and PW5 tried to prevent the stabbing and PW5 was injured in the process. Under Dickson Mwangi Munene v R and R v Tabulayenka, common intention requires a shared intention or pre-arranged plan, and may be negated where parties disassociate themselves from the assault.
Failure to call the watchman Peter Maina as a witness
The failure was not fatal; calling witnesses is within the prosecution's discretion absent oblique motive, and his evidence's materiality was not shown.
Under section 143 of the Evidence Act no particular number of witnesses is required. Applying Mwangi v R, the Court declined to draw a negative inference because there was no indication of the possible materiality of Peter Maina's evidence or of any oblique motive for his exclusion.
Right to interpretation under Article 50(2)(n)
The ground failed; the appellant, represented by counsel, pleaded and gave an unsworn statement in Kiswahili and never raised the language issue before the trial judge, so no prejudice was shown.
The Court found nothing on record establishing that the appellant did not understand Kiswahili, and his counsel never alerted the trial judge to any language difficulty. Without demonstrated prejudice, the claim that Article 50(2)(n) was breached could not succeed.
Legal principles established
#- On a first appeal, the Court of Appeal must re-evaluate and analyse the facts and evidence afresh and arrive at its own conclusions, making allowance for the trial court's advantage of seeing and hearing witnesses.
- The defence of intoxication is very narrow and must be read within the confines of section 13(1), (2)(a) and (b) of the Penal Code; a mere plea of drunkenness will not negative mens rea.
- A failure by the prosecution to call a particular witness is not fatal where there is no indication of the materiality of that witness's evidence or of an oblique motive; no negative inference should be drawn.
- Section 143 of the Evidence Act provides that no particular number of witnesses is required to prove any fact.
