"Where on a charge of murder there is evidence on which the jury can find that the person charged was provoked (whether by things done or by things said or by both together) to lose his self-control, the question whether the provocation was enough to make a reasonable man do as he did shall be left to be determined by the jury; and in determining that question the jury shall take into account everything both done and said according to the effect which, in their opinion, it would have on a reasonable man."
"It means an ordinary person of either sex, not exceptionally excitable or pugnacious, but possessed of such powers of self-control as everyone is entitled to expect that his fellow citizens will exercise in society as it is today."
"The test to be applied is that of the effect of the provocation on a reasonable man .... so that an unusually excitable or pugnacious individual is not entitled to rely on provocation which would not have led an ordinary person to act as he did."
"He should ... explain to them that the reasonable man referred to in the question is a person having the power of self-control to be expected of an ordinary person of the sex and age of the accused, but in other respects sharing such of the accused's characteristics as they think would affect the gravity of the provocation to him; and that the question is not merely whether such a person would in like circumstances be provoked to lose his self-control but also whether he would react to the provocation as the accused did." (Emphasis added)
"suppose that a man who has been in prison for a sexual offence, for example rape, has after his release been taunted by another man with reference to that offence. It is difficult to see why, on ordinary principles, his characteristic or history as an offender of that kind should not be taken into account as going to the gravity of the provocation."
"But this is a far cry from the defendant's submission that the mental infirmity of a defendant impairing his power of self-control should as such be attributed to the reasonable man for the purposes of the objective test."
"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."
"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 control other than those influences which have been self-induced" (Emphasis added).
"A crucial factor in the defence of provocation from earliest times has been the relationship between the gravity of provocation and the way in which the accused retaliated, both being judged by the social standards of the day … But so long as words unaccompanied by violence could not in law amount to provocation the relevant proportionality between provocation and retaliation was primarily one of degrees of violence. Words spoken to the accused before the violence started were not normally to be included in the proportion sum. But now that the law has been changed so as to permit of words being treated as provocation even though unaccompanied by any other acts, the gravity of verbal provocation may well depend upon the particular characteristics or circumstances of the person to whom a taunt or insult is addressed."
"If the jury think that the same power of self-control is not to be expected in an ordinary, average or normal boy of 15 as in an older person, are they to treat the lesser powers of self-control possessed by an ordinary, average or normal boy of 15 as the standard of self-control with which the conduct of the accused is to be compared?"
"To consider the mind of some different person, and to consider what his reactions would have been if comparably provoked could involve an unreal test."
"It may be conceded that in strict logic there is a transition between treating age as a characteristic that may be taken into account in assessing the gravity of the provocation addressed to the accused and treating it as a characteristic to be taken into account in determining what is the degree of self-control to be expected of the ordinary person with whom the accused's conduct is to be compared. But to require old heads upon young shoulders is inconsistent with the law's compassion to human infirmity to which Sir Michael Foster ascribed the doctrine of provocation more than two centuries ago. The distinction as to the purposes for which it is legitimate to take the age of the accused into account involves considerations of too great nicety to warrant a place in deciding a matter of opinion, which is no longer one to be decided by a judge trained in logical reasoning but is to be decided by a jury drawing on their experience of how ordinary human beings behave in real life."
"In my view it would now be unreal to tell a jury that the notional 'reasonable man' is someone without the characteristics of the accused: it would be to intrude into their province. A few examples may be given. If the accused is of particular colour or particular ethnic origin and things are said which to him are grossly insulting it would be utterly unreal if the jury had to consider whether the words would have provoked a man of different colour or ethnic origin – or to consider how such a man would have acted or reacted. The question would be whether the accused if he was provoked only reacted as even any reasonable man in his situation would or might have reacted."
"I think that the standard of self-control which the law requires before provocation is held to reduce murder to manslaughter is still that of the reasonable person (hence his invocation in section 3); but that, in determining whether a person of reasonable self-control would lose it in the circumstances, the entire factual situation, which includes the characteristics of the accused, must be considered."
"The jury would, as ever, use their collective common sense to determine whether the provocation was sufficient to make a person of reasonable self-control in the totality of the circumstances (including personal characteristics) act as the defendant did. I certainly do not think that that is beyond the capacity of a jury."
"In this country the law on this matter [provocation] has been indirectly affected by the introduction of the defence of diminished responsibility. It is now possible for a defendant to set up a combined defence of provocation and diminished responsibility, the practical effect being that the jury may return a verdict of manslaughter if they take the view that the defendant suffered from an abnormality of mind and was provoked. In practice this may mean that a conviction of murder will be ruled out although the provocation was not such as would have moved a person of normal mentality to kill."
"The proper distinction … is that individual peculiarities which bear on the gravity of the provocation should be taken into account, whereas individual peculiarities bearing on the accused's level of self-control should not."
"The life of the law has not been logic: it has been experience. The felt necessities of the time, the prevalent moral and political theories, intuitions of public policy, avowed or unconscious, even the prejudices which judges share with their fellow-men, have had a good deal more to do than the syllogism in determining the rules by which men should be governed."
"The general principle is that the same standards of behaviour are expected of everyone, regardless of their individual psychological make-up. In most cases, nothing more will need to be said. But the jury should in an appropriate case be told, in whatever language will best convey the distinction, that this is a principle and not a rigid rule. It may sometimes have to yield to a more important principle, which is to do justice in the particular case. So the jury may think that there was some characteristic of the accused, whether temporary or permanent, which affected the degree of control which society could reasonably have expected of him and which it would be unjust not to take into account. If the jury take this view, they are at liberty to give effect to it."
