The State v Tavonga Mupinga

On the night of 13 March 2017, the accused and the deceased were drinking beer at Musakaruka shop at Yellow Farm Range, Masvingo. A misunderstanding arose between them, culminating in a fist fight around 21:00 hrs, which was broken up by other patrons. The deceased left the shop first, ostensibly going home. The State alleged that the accused followed the deceased and stabbed him with a knife below the armpit, resulting in his death. The deceased's body was discovered the next morning on 14 March 2017. The accused was linked to the offence by his woollen hat and knife found at the scene, and his blood-stained t-shirt. The post-mortem report showed the cause of death was a stab wound that penetrated the lung, causing excessive blood loss. The accused admitted stabbing the deceased but claimed self-defence, stating that the deceased had waylaid him, throttled him, sat on top of him, and stabbed him in the face with a sharp object, forcing him to use his knife to fend off the attack.

• Whether the accused could successfully raise the defence of self-defence in terms of s 253(1) of the Criminal Law (Codification and Reform) Act [Cap 9:23]
• Whether the State proved beyond reasonable doubt that the accused murdered the deceased
• Whether the accused exceeded the bounds of legitimate self-defence when he stabbed the deceased
• Whether the application for discharge at the close of the State's case in terms of s 198(3) of the Criminal Procedure and Evidence Act should be granted

The accused was found not guilty of murder and acquitted.

Where an accused raises the defence of self-defence and the State fails to negative that defence beyond reasonable doubt, the accused must be acquitted. In assessing whether an accused exceeded the bounds of legitimate self-defence, the court must objectively consider all relevant circumstances including: (1) whether the accused was the aggressor or was attacked unexpectedly; (2) the relative physical capabilities of the parties; (3) the nature and severity of the attack; (4) whether the accused had been overpowered; (5) whether the force used was a last resort; and (6) whether the degree of force was proportionate to the threat faced. The fact that death resulted does not preclude the defence, as the law permits causing death to an unlawful attacker in appropriate circumstances. Where there is doubt as to whether the defence has been negatived, that doubt must be resolved in favour of the accused.

The court expressed serious concern about the manner in which the investigation was conducted, noting that all civil witnesses disowned the statements attributed to them and that one witness specifically alleged his signature was forged. The court stated that "the manner this matter was investigated leave a lot to be desired" but declined to comment further. The court also noted that the accused's conduct after the incident (fleeing the scene) was irrelevant to the assessment of self-defence, particularly given his intoxicated state. The court observed that it was "fortuitous" that the single blow struck the deceased below the armpit, suggesting the accused had not aimed for a particularly vulnerable area but struck randomly to free himself.

This case is significant in Zimbabwean criminal law (which shares substantial common law heritage with South African law) as it demonstrates the application of the complete defence of self-defence in homicide cases. It emphasizes that where the State fails to disprove a legitimate claim of self-defence beyond reasonable doubt, the accused must be acquitted even where death has resulted. The case also highlights the importance of proper police investigation and the consequences of witnesses disowning their statements, which undermines the prosecution's case. It illustrates the objective test to be applied when assessing whether an accused exceeded the bounds of legitimate self-defence, taking into account factors such as the nature of the attack, the relative physical capabilities of the parties, intoxication, the unexpectedness of the attack, and whether the force used was proportionate and a last resort.
