During the early hours of 12 June 1999, on Ou Kaapseweg near Fish Hoek, the appellant, Graeme Michael Eadie, assaulted and killed Kevin Andrew Duncan in a road‑rage incident. After a series of aggressive driving encounters, Eadie stopped his vehicle, armed himself with a hockey stick, approached the deceased’s car and launched a sustained and violent attack, including repeated blows and stamping on the deceased’s head, causing fatal injuries. Eadie had consumed a substantial quantity of alcohol. After the assault, he attempted to mislead the police and disposed of the hockey stick. At trial he admitted the killing but raised a defence of temporary non‑pathological criminal incapacity based on emotional stress, provocation and intoxication. The Cape Provincial Division rejected the defence, convicted him of murder and obstruction of justice, and sentenced him accordingly. He appealed against the murder conviction only.
The appeal against the conviction for murder was dismissed, and the conviction and sentence imposed by the High Court were confirmed.
This case is a leading authority in South African criminal law on the defence of non‑pathological criminal incapacity. It significantly curtailed the scope of the defence by equating it with sane automatism and reaffirming that anger, stress, provocation and intoxication rarely negate criminal capacity. The judgment reinforced judicial scepticism toward the defence and aimed to restore public confidence in the criminal justice system.
