“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 done and said according to the effect which, in their opinion, it would have on a reasonable man.”
“There would have been no difficulty therefore in the trial judge coming to the conclusion that there was evidence of provoking conduct on the part of the group. What seems to have created the difficulty is the absence of any evidence of loss of self control. The judge considered that the response of the appellant was a measured one. He appeared to be in control at all times. The appellant himself was conscious of the fact that the group might get hold of his firearm so he was braking the blows with one hand and shielding the firearm with the other. And he was in control to the extent that while under attack he could pinpoint Ryan coming at him with a knife and, in defence of his person, deliberately shot him (albeit in his view with no intention to harm him).”
“Looked at as a whole it is not possible to find fault with the trial judge's decision not to put the issue of provocation for the jury's consideration. One is compelled to agree with him that the appellant's response to the attack was indeed a measured one and not the response of someone who has lost his self-control. The others were attacking and beating him but amidst it all he was able to single out the deceased and Ryan (the ones with the knives) and shoot them in defence of his person, at the same time exercising restraint in respect of the others who were attacking him (without knives). It had all the appearances of a decisive response by someone in total control notwithstanding the attack.”
