The State v Merjury Murira

On 19 November 2020, Merjury Murira discovered that her husband, Taruwinga Muhwati (the deceased), had impregnated her 15-year-old daughter Prudence from a previous marriage. When the accused confronted the deceased, he proposed that Prudence become his second wife while the accused would be relegated to a housemaid. The accused refused. From the afternoon until late into the night, the deceased subjected the accused to protracted, severe physical assault and torture. He beat her with switches, fists, elbows, and logs; stuffed soil in her mouth to muffle her cries; forcibly undressed her in front of her children and exposed her genitals; denied her food; threatened to kill her before daybreak; and had sexual intercourse with Prudence in the accused's presence while taunting her. The deceased kept an axe and knife nearby and threatened to use them. Around midnight, fearing for her life as the deceased had repeatedly threatened to kill her, the accused struck the deceased once on the chin with an axe while he lay next to Prudence. He died instantly from severe head trauma. The accused fled and was arrested shortly thereafter.

• Whether the accused possessed the requisite mens rea (intention) for murder
• Whether the defence of self-defence was available to the accused in circumstances where the attack appeared to have paused
• Whether the use of a lethal weapon (axe) was a reasonable means to avert the attack
• Whether the defence of provocation could reduce murder to culpable homicide
• Whether all requirements for self-defence under section 253 of the Criminal Law Codification and Reform Act were satisfied

The accused was found not guilty of murder and acquitted. The court recommended that the Department of Social Welfare provide counselling to both the accused and her daughter Prudence.

A person who kills their attacker in self-defence will be acquitted of murder where: (1) there was an unlawful attack that had commenced or was imminent and continuing; (2) the accused reasonably believed further deadly attacks were imminent based on sustained violence and explicit threats of death; (3) the action taken was necessary to avert the attack; and (4) the means used were reasonable in the circumstances, even if lethal force is employed, where the accused faced imminent danger to life and had no opportunity to carefully assess alternatives or precisely aim defensive blows. In evaluating self-defence claims, courts must not take an "armchair approach" but must robustly assess reasonableness from the perspective of a person under sustained violent attack. Where self-defence is established, neither murder nor culpable homicide can be sustained because the accused had a lawful right to defend themselves.

The court made significant non-binding observations: (1) It suggested that the defence of provocation might be extended beyond "heat of the moment" situations to include cases of cumulative provocation where an accused is "gradually trolled until he or she reaches break point," noting this form of provocation "may actually be more dangerous" than sudden provocation, though the court left this issue open for future debate. (2) The court made strong observations about the extreme nature of the provocation in this case, describing it as embodying "several species of domestic violence" including physical, sexual, and emotional abuse. (3) The court emphasized the need for counselling and therapeutic intervention for both the accused and her daughter as victims of severe abuse and trauma. (4) The court noted that sexual intercourse between the deceased and Prudence was "taboo" and "the worst thing that any mother can imagine happening to her," and that forcing the accused to witness it constituted extreme sexual abuse. These observations highlight judicial recognition of the severe psychological impact of domestic violence and the need for holistic responses beyond criminal sanctions.

This case is significant in Zimbabwean criminal law for several reasons: (1) It robustly applies the self-defence provisions under s 253 of the Criminal Law Codification and Reform Act in the context of severe domestic violence, confirming that self-defence may be available even when there is an apparent pause in violence if threats of imminent deadly harm persist. (2) It recognizes the realities faced by victims of sustained domestic abuse and torture, rejecting an "armchair approach" to evaluating reasonableness of defensive action. (3) It confirms that in circumstances of imminent danger to life, the use of lethal force may be excusable, and victims need not precisely calibrate their defensive response or choice of weapon when acting under extreme duress. (4) The court's obiter comments suggest potential for expanding the doctrine of provocation to include cumulative provocation over time rather than only heat-of-the-moment reactions. (5) It illustrates intersection of domestic violence, sexual abuse, and gender-based violence in the criminal justice system. The case demonstrates judicial sensitivity to the dynamics of severe marital abuse and the psychological state of victims who kill their abusers.
