The bottom line

#

Kenya's Court of Appeal ruled that if self-defence is raised, the prosecution must disprove it beyond reasonable doubt or the accused must go free.

What this practically means

#

Executive summary

#
This is a Court of Appeal judgment at Nakuru allowing an appeal against conviction for manslaughter contrary to section 205 of the Penal Code and a sentence of four years imprisonment imposed by the High Court at Eldoret. The appellant, a police sergeant, shot and killed the deceased, a police inspector, at Lessos trading centre on the night of 16th July 1990 after responding to a report of an armed stolen vehicle. The deceased had brandished a pistol at bar staff earlier that night; when police officers knocked at his lodging-room door, he flung it open and pointed the pistol at the appellant, who fired his G3 rifle impulsively. The trial Judge had found that the appellant acted under an apprehension that he was likely to be shot, yet convicted him of manslaughter on the basis that the force used in self-defence was excessive. The Court of Appeal restated the law on self-defence, drawing on English authorities: the plea is one of justification which the prosecution must disprove beyond reasonable doubt, and the test of reasonableness is not purely objective but must take account of the accused's perception of danger, his capacities and the emotional strains of the moment. Applying that law to the trial Judge's own findings, the court held that the prosecution had not disproved the appellant's plea of self-defence and quashed the conviction, set aside the sentence, and ordered the appellant's immediate release unless otherwise lawfully held. The sentence complaint was not addressed as it had become unnecessary.

Questions the Court framed

#

The issues the Court set itself to decide, in its own words.

  1. 1.Whether the prosecution disproved the appellant's plea of self-defence beyond reasonable doubt
  2. 2.Whether the test of reasonableness in self-defence is purely objective or takes account of the accused's state of mind
  3. 3.Whether the conviction of manslaughter contrary to section 205 of the Penal Code could stand where the plea of self-defence was not disproved
  4. 4.Whether the sentence of 4 years imprisonment was excessive

Key legal issues

#
01

Standard of proof where self-defence is raised

Holding

Self-defence is a plea of justification; the prosecution must disprove it beyond reasonable doubt as part of its case before a conviction can stand

Reasoning

By pleading self-defence the accused asserts he committed no unlawful act. Because the burden of proving guilt rests on the prosecution throughout, the plea forms part of the case the prosecution must disprove beyond reasonable doubt. The English authorities cited reinforce that a guilty verdict cannot be justified where the plea remains unresolved on the evidence. In this case the plea was never displaced, so the conviction for manslaughter could not be sustained.

p. 2
02

Objective versus subjective test of reasonableness in self-defence

Holding

The reasonableness of the accused's defensive action must be judged with reference to his honest and instinctive perception of danger, his capacities and the emotional stress of the moment, not by detached objective standards alone

Reasoning

The court adopted the approach in R v Whyte and Shannon v R that the state of mind of the accused - his view of the danger threatening him - is material. What is reasonable combines the dispassionate outsider's viewpoint with that of the accused, with his intellectual capabilities and emotional strains at the moment of unexpected anguish. In a crisis requiring instant action, what the accused honestly and instinctively thought necessary may be the only reasonable defensive action.

p. 2
03

Application to the facts: whether the plea of self-defence was disproved

Holding

The trial Judge's own findings showed the appellant acted under a genuine apprehension of being shot when the deceased pointed a pistol at him after the door was suddenly opened; the prosecution failed to disprove self-defence and the conviction was unsafe

Reasoning

The deceased suddenly flung open the door and confronted the appellant with a pistol after the appellant had kicked it four times. The trial Judge found the accused believed he was being shot at, though no shot was ever fired. Applying the correct legal test to those findings, the appellate court held the plea of self-defence was not disproved and the conviction for the lesser offence of manslaughter could not be upheld.

p. 3

Legal principles established

#
  • Self-defence is a plea of justification which the prosecution must disprove beyond reasonable doubt as an essential part of its case before a guilty verdict is justified
  • The test of reasonableness in self-defence is not purely objective; the accused's perception of danger and his capacity and emotional state at the moment of crisis are material

Quotable passages

#

Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.

Accordingly, we allow this appeal, quash the conviction and set aside the sentence. The appellant is to be set at liberty forthwith unless otherwise lawfully held in custody.
p. 3Disposition - appeal allowed, conviction quashed, sentence set aside, release ordered
Self-defence is a plea of justification and by that plea the accused is saying that he committed no unlawful act.
p. 2Nature of the plea of self-defence and burden on the prosecution
The test of reasonableness is not, to put it at its lowest, a purely objective one.
p. 1Subjective element in the test of reasonableness in self-defence
Indeed, at the conclusion of the appellant’s trial before the High Court at Eldoret, his plea that he had committed no unlawful act starkly remained begging to be resolved.
p. 3Prosecution's failure to disprove self-defence on the evidence
