Craig William Grigor v The State

On 11 January 2008, a road rage incident occurred along Kirshner Road, Benoni, between the appellant and the complainant. After an exchange of gestures while driving, both parties alighted from their vehicles. The complainant pushed the appellant, initiating a physical confrontation. During the ensuing fight, the appellant, who was armed with both a knife and a firearm, inflicted multiple stab wounds on the unarmed complainant using the knife. The complainant sustained serious injuries including deep lacerations on his face, chest, abdomen (which penetrated the abdomen and severed a rib), and right thigh. Medical evidence indicated the complainant could have died from bleeding without medical intervention. The appellant was convicted of attempted murder in the regional court, Benoni, and sentenced to six years' imprisonment. He appealed to the North Gauteng High Court, which dismissed his appeal. He then appealed to the Supreme Court of Appeal with leave.

• Whether the appellant acted in self-defence when stabbing the complainant
• Whether there was a reasonable relationship between the attack and the defensive act
• Whether the bounds of self-defence were exceeded
• Whether the sentence of six years' imprisonment was appropriate

The appeal against both the conviction and the sentence was dismissed.

For self-defence to succeed, there must be a balance and reasonable relationship between the attack and the defensive act. The defensive act must be necessary to protect oneself and proportionate to the threat faced. The use of deadly force (a knife inflicting multiple severe stab wounds) in response to a threat of assault (pushing) is disproportionate and exceeds the bounds of self-defence. When an accused person had harmless means available to avoid confrontation but instead chose to engage and use excessive force, the defence of self-defence fails. The severity of injuries inflicted is objective evidence relevant to determining whether the force used was proportionate and whether self-defence was genuine.

The court observed, citing Snyman's Criminal Law, that it is not feasible to formulate the nature of the relationship which must exist between attack and defence in precise and abstract terms, and that this requirement is in practice a matter of fact rather than law. The court also noted approvingly Snyman's illustration that there ought to be a certain balance between attack and defence: 'you may not shoot and kill another person who strikes you with a fly-swatter.' The court commented that even if the appellant was angry and wanted to retaliate and confront the complainant, there was no basis to find he was justified in using the knife or the consequent force used in stabbing the complainant. The court observed that the appellant's explanation for stopping his vehicle (to avoid the complainant seeing his workplace) was implausible and nonsensical given his subsequent conduct of alighting hastily and advancing towards the complainant.

This case is significant in South African criminal law as it clarifies the requirements for a successful defence of self-defence (private defence), particularly the requirement of proportionality between the attack and the defensive act. The judgment provides guidance on how courts should assess competing versions in road rage incidents and emphasizes that self-defence requires a reasonable relationship between the threat faced and the force used in response. It reaffirms that the use of deadly force in response to a threat of mere assault exceeds the bounds of lawful self-defence. The case also demonstrates the proper approach courts should take when faced with two conflicting versions, requiring an assessment of all probabilities cumulatively to determine whether guilt has been proved beyond reasonable doubt.
