have wrestled with it constantly and by no means to their satisfaction. For such arbitrariness is largely inherent in the nature of the proceedings from start to finish. Similar trouble may be inescapable, to be sure, in cases that are not capital ones. But in those producing sentences of death the arbitrariness is intolerable because of the irreversibility of the punishment once that gets put into force and the consequent irremediability of mistakes discovered afterwards, mistakes which do occur now and then notwithstanding the myth to the contrary. The defect then militates forcefully, I believe, against the reasonableness and justifiability of capital punishment.
[186]The conclusion to which I have thus come, echoing the one reached by Chaskalson P, is that the death penalty cannot survive our constitutional scrunity of it. The line I have taken in arriving there differs in some parts from that preferred by him, occasionally approaching a topic from another angle and sometimes placing the emphasis elsewhere. It has also called for less elaboration in the light of his meticulous research into a mountain of material and his erudite exposition of the themes developed from that. In general, however, I agree with his judgment, a profound and monumental work with which I feel proud to associate myself.
[187]I wish before ending this judgment to add my voice to that of Chaskalson P in dealing with a couple of points raised in argument on which he has commented already but which I have not yet mentioned.
[188]Whether capital punishment ought to be abolished or retained amounted, so it was said, to a question of policy which Parliament should decide, representing as it did the citizens of the country and expressing their general will. The issue is also, however, a constitutional one. It has been put before us squarely and properly. We cannot delegate to Parliament the duty that we bear to determine it, or evade that duty otherwise, but must perform it ourselves. In doing so, we were counselled in the alternative, we had to pay great attention to public opinion, which was said to favour the retention of the death penalty. We have no means of ascertaining whether that is indeed so, but I shall assume it to be the case. One may also assume, with a fair measure of confidence, that most members of the public who support capital punishment do so primarily in the belief that, owing to its uniquely deterrent force, they and their families are safer with than without its protection. The feeling is quite understandable, given its basis. But it deserves no further homage if the premise underlying and accounting for it is fallacious or unfounded, as I consider that one to be. To allow ourselves to be influenced unduly by public opinion would, in any event, be wrong. Powell J disparaged such external pressures on constitutional adjudication when he said in Furman v State of Georgia (at 443):
(T)he weight of the evidence indicates that the public generally has not accepted either the morality or the social merit of the views so passionately advocated by the articulate spokesmen for abolition. But however one may assess (the) amorphous ebb and flow of public opinion generally on this volatile issue, this type of enquiry lies at the periphery—not the core—of the judicial process in constitutional cases. The assessment of popular opinion is essentially a legislative, not a judicial, function.
In similar vein were these remarks passed by Jackson J on the earlier occasion of West Virginia State Board of Education v Barnette and Others (1942) 319 U5 624 (at 638):
