The bottom line

#

Kenya's Court of Appeal confirmed that self-defence fails when you started the fight or no one was attacking you.

What this practically means

#

Executive summary

#
The Court of Appeal at Nairobi (Kneller, Nyarangi and Chesoni, JJ of Appeal) dismissed the appellant's appeal against his conviction of manslaughter and three years' imprisonment imposed by Aluoch J in the High Court at Nairobi for unlawfully killing Joseph Mathenge on 16 February 1983. The dispute arose at work over the use of a single hose pipe to fill equipment with water; the appellant pulled the deceased down from a fork lift, chased him while he was unarmed, and struck him on the back of the head with an iron bar, causing death from a fractured skull. The appeal was mounted on three grounds: that the trial judge wrongly rejected the defence of self-defence without giving sufficient reasons, that she failed to treat five eyewitnesses as unreliable for rejecting the appellant's alleged drunkenness, and that she erred in finding the injuries could not have been caused by a fall. The court rejected all grounds. It held self-defence was unavailable because the appellant was under no attack or threat of attack; that witnesses mistaken on a collateral fact are not untruthful, and the trial judge was entitled to believe them; and that the eyewitness evidence of the blows excluded a fall as the cause of injury. The court described the three-year sentence as lenient, though the respondent conceded it was reasonable. The appeal against both conviction and sentence was dismissed.

Questions the Court framed

#

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

  1. 1.Whether the trial judge misdirected herself in rejecting the defence of self-defence without giving sufficient reasons
  2. 2.Whether the trial judge erred in failing to treat five prosecution witnesses as unreliable for rejecting the appellant's drunkenness
  3. 3.Whether the injuries to the deceased could have been caused by a fall on a hard floor rather than the appellant's blows

Key legal issues

#
01

Availability of the defence of self-defence

Holding

Self-defence was not available because the appellant was the aggressor and was under no attack or threat of attack.

Reasoning

The court reviewed the sequence of events: the appellant tried to snatch the hose pipe, pulled the deceased down from the fork lift, chased him while he was unarmed and running away, and fatally struck him on the back of the head with an iron bar. Throughout, the appellant was the aggressive party and the deceased posed no threat, so there was nothing for the appellant to defend against.

02

Credibility of the five eyewitnesses on the drunkenness issue

Holding

The trial judge was entitled to believe the witnesses; their evidence that the appellant was not drunk was not a basis for treating them as unreliable.

Reasoning

The witnesses had not seen the appellant drinking and there was no medical or other evidence of alcohol; their statements that he was not drunk were expectations based on company regulations. A witness mistaken on a collateral fact is not thereby untruthful, and the trial judge who saw and heard them believed them on all other matters, so the appellate court had no reason to interfere.

p. 2
03

Whether the fatal injuries could have been caused by a fall on a hard floor

Holding

The eyewitness evidence of the blows excluded the possibility that the injuries were caused by a fall.

Reasoning

Multiple eyewitnesses saw the appellant strike the deceased on the back of the head with an iron bar, after which the deceased fell. The autopsy by Doctor Ribeiro established bleeding over the brain due to a fractured skull from a blunt object, with the skull broken into many pieces. The direct evidence of the blows ruled out the fall theory.

p. 3

Legal principles established

#
  • The defence of self-defence is unavailable to an accused who was under no attack or threat of attack
  • A witness may be mistaken on a collateral fact without being untruthful, and an appellate court will not interfere with findings of fact based on demeanour of witnesses the trial court saw and heard

Issues in the judgment

#
minor

Typographical error in the final orders: 'We order his appeal against conviction and sentence to dismissed' (grammatically incorrect, but the intent to dismiss is clear)

minor

The coram lists the trial judge as 'Oluoch, J' in the header but 'Mrs Justice Aluoch' in the body - same judge, inconsistent spelling
