For the defence of provocation under section 239 of the Criminal Code to reduce murder to culpable homicide, the accused must have completely lost self-control as a result of provocation sufficient to make a reasonable person lose self-control, and must have acted spontaneously in the heat of the moment. The reaction must be sudden, with the person acting on the spur of the moment having temporarily lost power of self-control and not appreciating what they are doing (applying Attorney General v Tobaiwa and Ors 1980 ZLR 192). Where an estranged spouse has already left the accused, made clear she will not return, and the accused pursues her to inflict punishment for rejecting reconciliation, this does not constitute acting under provocation with complete loss of self-control. The ability to recall specific details of the incident and minimize the extent of violence used indicates the accused retained appreciation of his actions and did not lose self-control. Multiple deep stab wounds inflicted with a lethal weapon demonstrate intention to kill or realization of the risk of death, sufficient for murder conviction.
