“In my view the section requires that the jury should ask what could reasonably be expected of a person with the accused’s characteristics. … It is thus not enough for the accused to say “I am a depressive, therefore I cannot be expected to exercise self-control.”
“It follows, in my opinion, that it would not be consistent with section 3 for the judge to tell the jury that they should ignore any factor or characteristic of the accused in deciding whether the objective [i.e. the second] element of provocation has been satisfied. That would be to trespass upon their province.”
“In my opinion, therefore, judges should not be required to describe the objective element in the provocation defence by reference to a reasonable man, with or without attribution of personal characteristics. They may instead find it more helpful to explain in simple language the principles of the doctrine of provocation. First, it requires that the accused should have killed while he lost self-control and that something should have caused him to lose self-control. For better or for worse, section 3 left this part of the law untouched. Secondly, the fact that something caused him to lose self-control is not enough. The law expects people to exercise control over their emotions. A tendency to violent rages or childish tantrums is a defect in character rather than an excuse. The jury must think that the circumstances were such as to make the loss of self-control sufficiently excusable to reduce the gravity of the offence from murder to manslaughter. This is entirely a question for the jury. In deciding what should count as a sufficient excuse, they have to apply what they consider to be appropriate standards of behaviour; on the one hand making allowance for human nature and the power of the emotions but, on the other hand, not allowing someone to rely upon his own violent disposition. In applying these standards of behaviour, the jury represent the community and decide …. What degree of self-control “everyone is entitled to expect that his fellow citizens will exercise in society as it is today”
“My lords, I do not wish to lay down any prescriptive formula for the way in which the matter is explained to the jury. I am sure that if judges are freed from the necessity of invoking the formula of the reasonable man equipped with an array on unreasonable “eligible characteristics”, they will be able to explain the principles in simple terms. Provided that the judge makes it clear that the question is in the end one for the jury and he is not seeking to “impose a fetter on the right and duty of the jury which the Act accords to them”, the guidance which he gives must be a matter for his judgment on the facts of the case.”
“The reasonable person in such a case should be one who is exercising a reasonable level of self-control for someone with her history, her experience and her state of mind. On such an approach the jury should be perfectly capable or returning a realistic answer and thus achieve a verdict which would fairly meet any peculiarities of the particular case consistently with the recognition of the importance of curbing temper and passion in the interest of civil order.”
“It seems to me that the standard of reasonableness in this context should refer to a person exercising the ordinary power of self-control over his passions which someone in his position is able to exercise and is expected by society to exercise. By position I mean to include all the characteristics which the particular individual possesses and which may in the circumstances bear on his power of self-control other than those influences which have been self-induced. Society should require that he exercise a reasonable control over himself, but the limits within which control is reasonably to be demanded must take account of characteristics peculiar to him which reduce the extent to which he is capable of controlling himself. Such characteristics as an exceptional pugnacity or excitability will not suffice. Such tendencies require to be controlled. Section 3 requires that the accused should have made reasonable efforts to control himself within the limits of what he is reasonably able to do. This is not to destroy the idea of the reasonable man not to reincarnate him; it is simply to clothe him with a reasonable degree of reality. But as the statute prescribes, the matter comes to be one of the circumstances of the case and the good sense of the jury. Although the statute expressly refers to a reasonable man it does not follow that in directing a jury on provocation a judge must in every case use that particular expression. The substance of the section may well be conveyed without necessarily importing the concept of a reasonable man.”
