5. While Kant’s account of morality includes both the legal and the ethical, “moral” will be used interchangeably with “ethical” in this essay (unless otherwise specifed) in order to highlight the distinction between moral and legal desert. While I will argue that Kant allows an ethical dimension into his account of defences, it is a popular ethics and not his own ethics. His own ethics is sharply separated from his account of legality.

10. In Hill, this was also referred to as a reasonable person standard with “ordinary” and “reasonable” being used interchangeably. The Supreme Court of Canada now views this as an error and prefers the use of “ordinary” alone since “a reasonable person would not commit culpable homicide in the first place”; R v Tran, 2010 SCC 58, [2010] 3 SCR 350 at para 30 [Tran]. This article will accordingly use the phrase “ordinary person” except where quoting other individuals. The reasonableness of particular emotions is important in the Aristotelian moral framework below but the present legal test looks to the actions of the ordinary, rather than reasonable, person.

13. The majority suggested that a jury is right to “ascribe to the ordinary person any general characteristics relevant to the provocation in question…. [I]t would be impossible to conceptualize a sexless or ageless ordinary person. Features such as sex, age, or race do not detract from a person’s characterization as ordinary. Thus particular characteristics that are not peculiar or idiosyncratic can be ascribed to an ordinary person without subverting the logic of the objective test of provocation”; ibid at para 36.

14. See also ibid at para 81 (Wilson dissenting) 89 (Le Dain dissenting). The judgments differed with respect to judicial jury instruction procedure. Lamer J’s dissenting judgment challenging the adequacy of the jury charge seemed to exclude age as a relevant criterion, but he explicitly agreed with the majority’s legal analysis; ibid at paras 88-93.

Baker’s “‘last straw’ provocation, where an action which in itself appears insufficient to generate an angry response can be understood, in light of the cumulative effects of earlier provocation, as enough to overcome a defendant’s self-control” does not violate the rule since it maintains the suddenness requirement in a new form; Baker, supra note 43 at 196. As noted above, the lack of a suddenness requirement in Britain suggests it may not fulfill these essential requirements and Britain would do well to reconsider its theoretical bases for mitigation.

E.g., Ramsey suggests “a provocation claim should operate as a partial justification…[because] it was prompted by a legitimate, morally defensible valuation that comported with evolving social norms and substantive equality principles”; Ramsey, supra note 58 at 98.

88. An anonymous reviewer rightly questions whether the ordinary person requirement is a justificatory element of the defence. The review rightly notes that it would be odd to suggest that the commission of a wrongful act is justified because an ordinary person could commit it. An act’s moral wrongfulness is not negated through its commission by others alone. While I am tempted to point out that is not the act that is justified, I am cognizant of the fact that the ordinary person requirement may not justify the initial loss of self-control either. I am alive to this criticism and thus willing to refer to it as a justificatory-type element to demonstrate that its functional aim of providing an account of why the loss of self-control is not morally wrongful may not be fully realized.

112. Aristotle, supra note 89 at 1179 b27-1180 a14. Aristotle provides a hint that the purpose of the state could also be the material conditions for this realization of the well-lived life. He suggests “it is impossible, or not easy, to do noble acts without the proper equipment”; ibid at 1099 a20-b10. This could imply that a truly just state concerned with its citizens’ attainment of virtue (and, thus, the well-lived life) would be required to provide the materials necessary to realize it. It is clear that the state must provide programs that habituate one to act in accordance with virtue. Minimal materials must be provided such that people can act in accordance with virtue and develop the habit. How far this requirement extends is not detailed in Nicomachean Ethics and is beyond the scope of this article.

113. Temperance is concerned with the “pleasures of touch” and is the intermediate between too much physical activity (self-indulgence) and too little (insensibility); see Nicomachean Ethics 1117 b13-1119 a26. Liberality and magnificence, the virtues concerned with wealth, can be understood as means between wastefulness and miserliness; see Nicomachean Ethics at 1119 b19-1123 b8. Virtues of social intercourse are similarly constructed as means between excesses and deficiencies; see Nicomachean Ethics 1126 a26-1128 b12.

135. It is interestingly that Horder’s non-feminist reason for suggesting the abolition of the provocation defence is that “there is no moral justification for acting on a desire to take retribution personally”; Horder, Provocation, supra note 4 at 186. He actually provides a version of the Aristotelian rebuttal to this claim popular in the early modern period in far more than the 4 pages of the text devoted to making it.

Indeed, Horder later made use of Aristotelian notions of the mean. In Excusing Crime, he discusses partial excuses in terms of not going too far beyond what would normally be fully justified; Horder, Excusing, supra note 43 at 54-56.

170. Retribution of some sort is nonetheless relevant. Both the quality and quantity of punishment can only be definitely qualifed by “the law of retribution“, a law by which wrongdoing occasions punishment of a similar kind; ibid at 105-06. The punishment must relate to the crime.

Punishment is merely retributivist even in the legal retributivist sense. According to Ripstein, Kant’s conception of retribution requires deterrence; Ripstein, supra note 155 at 300-01. In the absence of every one respecting the law for its own sake, reciprocal limits on freedom require incentives for individuals to respect each other’s rights. Punishment systematizes these incentives while advanced promulgation of laws deters individuals from committing crimes, guiding their conduct through an incentive not to be punished for their lack of respect for reciprocal freedom; Ripstein, ibid at 306-07.

For the discussion of the true crimes/public welfare offences distinction (iii), see 9-10. Issues iv) and v) are raised on 1-2 with further treatment on liability and defences at 11-12.
