The State v Tinashe Shumba

On 11 September 2019, the accused, deceased (Lifalethu Johnson Ncube), and witness Pamela Mpofu were at Shangani Business Centre at a bar. After leaving the bar, the deceased accosted and attacked the accused. During the altercation, the accused produced a knife and stabbed the deceased in what he claimed was self-defence, resulting in the deceased's death. Pamela Mpofu, the state's witness, had left before the fight occurred and could not provide evidence about what transpired between the accused and deceased. The accused was the only person who gave evidence about the actual confrontation.

• Whether the accused unlawfully and intentionally killed the deceased (murder)
• Whether the accused acted in self-defence
• Whether the accused exceeded the bounds of lawful self-defence
• Whether the accused was negligent in using a knife against an unarmed person
• What is the appropriate conviction where self-defence is established but the force used was excessive

The accused was acquitted on the charge of murder and convicted of culpable homicide. He was sentenced to 7 years imprisonment with 2 years suspended for 5 years on condition that he does not commit an offence involving violence during that period, whereupon conviction he shall be sentenced to imprisonment without the option of a fine. Effective sentence: 5 years imprisonment (taking into account 2 years already served in remand).

Where an accused acts in self-defence but uses excessive force by introducing a deadly weapon (knife) against an unarmed attacker, the accused exceeds the bounds of lawful self-defence and is guilty of culpable homicide rather than murder. The use of a knife against an unarmed person in self-defence constitutes negligence and disproportionate force, resulting in criminal liability for culpable homicide even where the initial act of self-defence was justified.

The court noted that the state's witness Pamela Mpofu's testimony did not prove any allegations against the accused and could not disprove the accused's version of events. The court observed that the accused's version was the only evidence before the court regarding what transpired between him and the deceased, highlighting the state's failure to discharge its burden of proof on the murder charge. The court also considered mitigating factors in sentencing, noting the accused's youth, first offender status, and the fact that he had already spent 2 years in remand prison, which informed the decision to impose an effective 5-year sentence rather than the full 7 years.

This case illustrates the application of self-defence principles in Zimbabwean criminal law, particularly addressing the limits of lawful self-defence. It demonstrates that while a person may be entitled to defend themselves when attacked, the use of disproportionate force (such as using a deadly weapon against an unarmed attacker) can result in criminal liability for culpable homicide rather than complete acquittal. The case also reflects the court's approach to sentencing in cases where self-defence is partially established but excessive force was used, balancing mitigating factors such as youth, first offender status, and time already served in remand prison.
