After the decision by the Supreme Court of Canada in Lavallee, Canadian women who are victims of serious domestic abuse have been able to invoke an ‘enlarged’ conception of self-defence to exonerate some acts of killing abusers. While concern remains about Lavallee, this judgement broke important ground in insisting on a more sensitive account of the actual experience of abused women, and in giving recognition to the reasonable fears that such women have for their lives. However, other than self-defence, there is no criminal law defence or plea that has been effective as a (partial) excuse or justification for killings by abused women. In this paper, I will consider the potential for a plea of provocation to serve such a role. Provocation has acquired some standing in other jurisdictions as a defence for abused women who kill but it has not as yet been effectively used in Canada. I will look at the appropriateness of provocation as a plea in some abuser homicides. The paper will discuss some ways in which the plea of provocation could be enlarged in scope and in normative power; the paper will also examine some shortcomings of the current understanding of provocation to serve a defence for women who kill. Since homicides by women make up a small fraction of all homicides, even a reformed defence of provocation would be rarely used. But the more important question is whether a plea which has been available to men for several centuries should not also be (much more) available to women who kill, and whether closer attention to the situations and perspectives of women in abusive relationships yields good grounds for thinking some kill as excusable or reasonable responses to serious provocation. The underlying concern is an equality concern; that women have equal access to suitable defences for their putative breaches of the criminal law, and that standards of reasonableness operative in criminal case deliberation be as responsive to women’s experience and women’s values as they are to men’s.
