Under section 239(1) of the Criminal Law (Codification and Reform) Act, the defence of provocation can at most be a partial defence to a charge of murder, reducing it to culpable homicide. Public policy demands that provocation should only be a partial defence to murder, as the sanctity of human life must be protected and citizens must be encouraged to control their temper and use legal means to resolve disputes. In sentencing for culpable homicide arising from provocation, courts must balance aggravating factors (brutality of the attack, sanctity of life, need for deterrence) against mitigating factors (youthfulness, provocation, contrition, pre-trial incarceration). A wholly suspended sentence in crimes of passion would send wrong signals to the public, necessitating some custodial sentence even where significant mitigation exists.
