On the night of 7 April 2011 at Village A, Nyahukwe, Rusape, the accused and deceased were blood brothers sharing a homestead bequeathed by their late parents. The deceased arrived home and asked the accused's wife for matches, which led to an exchange. When the accused left his bedroom hut to calm his younger brother, the deceased redirected his insults at the accused and attacked him, triggering a physical fight. During the fight, which moved from the bedroom entrance to near a fowl run under construction, the accused felt he was losing and being crushed under his brother's grip. The accused reached for what he thought was an off-cut of pole from the construction site and swung it at his brother's left shoulder. The object turned out to be an axe, which struck the deceased on the neck, severing an artery. The deceased ran to a neighbour to report the incident and died soon after from the injuries sustained.
The accused was found not guilty of murder as defined in s 47(1) of the Criminal Law (Codification and Reform) Act [Cap 9:23], but guilty of culpable homicide as defined in s 49(1) of the same Act.
Where an accused person uses a weapon in self-defence against an unarmed attacker, even if the weapon was picked up inadvertently during a fight and without murderous intent, such action exceeds the bounds of reasonable self-defence and constitutes culpable homicide when death results. The test for self-defence is objective: a reasonable person in the accused's position must have acted in the same way for the defence to succeed. While the accused is entitled to use reasonably necessary force to defend against an unlawful attack, the use of a lethal weapon against an unarmed opponent is objectively unreasonable and unlawful, negating a complete defence but reducing murder to culpable homicide where there was no intention to kill.
The court endorsed the robust approach from S v Ntuli, stating that courts should not seek to measure "with nice intellectual callipers the precise bounds of legitimate self-defence." However, the court noted that even adopting such a robust approach, one cannot ignore the fact that the accused resorted to using a weapon where death resulted from that very weapon, regardless of whether the accused noticed it was an axe before or after striking the blow. The court observed that the result must be the same in either scenario.
This case illustrates the application of the objective test for self-defence in Zimbabwean criminal law, particularly the limits of reasonable force in response to an unlawful attack. It demonstrates that even where an accused acts without murderous intent and in response to unlawful provocation, the use of a weapon against an unarmed attacker may exceed the bounds of lawful self-defence and constitute culpable homicide. The case reinforces the principle that the reasonableness of defensive action must be assessed objectively, considering the proportionality of force used relative to the threat faced.
