Reformers in much of the common law world have recently turned their attentions to laws pertaining to murder and manslaughter; however, perceptions of the past maintain a hold. In England and Wales, the Coroners and Justice Act (2009) abandoned notions of provocation that developed in the seventeenth century, instead stipulating that “loss of control” would serve as the means of mitigating charges of murder to a lesser offence. If a person has reasonable grounds for losing control, of a sort that accords with contemporary norms and values, that loss of control can be adduced as a partial defense on a homicide charge. Concerns about blaming victims and gender bias have helped shape the shift away from provocation defenses. Whether a married woman's sexual infidelity might in some way serve as a partial defense that moderates her husband's killing of her from murder to something less serious has proven especially controversial. (The reverse, a wife killing an adulterous husband, receives far less attention, but then women kill their partners for any reason far less often.) Drafters of the 2009 act expressly abandoned the older notion that sexual infidelity constituted sufficient provocation to mitigate charges in a husband's killing of his wife. Angry, jealous men killing their spouses in revenge or a passionate rage might no longer cite infidelity as sufficient provocation to kill. Some people, including lawmakers and judges, expressed concerns about the change. One MP (and later attorney general) complained that “thousands of years of human experience and history should be jettisoned for a piece of political correctness.” He need not have worried: recently, the decision in R. v. Clinton (2012) reintroduced the substance of the defense in a new guise, seeing a wife's adultery not as provocation, but as a trigger for a husband's understandable “loss of control.” Among other factors, the Court of Appeal alluded to “experience over many generations” in treating a man's suspicion of his wife's sexual infidelity as reasonable grounds for mitigation.
