addition, he referred to an official State-wide referendum in the State of California adopting a constitutional amendment that authorised capital punishment.
[201]Needless to say, there was no similar evidence before us. Public opinion has not expressed itself in a referendum, nor in any recent legislation. Certainly, there is no evidence of a general social acceptance of the death penalty for murderers such as might conceivably have influenced our conclusions. On the contrary, developments in South Africa point in the opposite direction. It is to be noted that even at the time, during the previous decade, when South Africa had the unenviable reputation for carrying out more executions than any other country in the western world, only a proportion of those convicted of murder were sentenced to death, and of those many were reprieved. The amendment to the Criminal Procedure Act introduced by Act No 107 of 1990 drastically reduced the number of convicted murderers sentenced to death. The subsequent developments described by Chaskalson P including the official executive moratorium on the death penalty announced in March 1992, while not evidence of general opinion, do cast serious doubt on the acceptability of capital punishment in South Africa. In fact, we are informed, since 1989 there has been no judicial execution in South Africa. Thus there has been in this country no indication whatsoever of what Stewart J in Gregg's case referred to as "society's endorsement of the death penalty for murder." In the Constitution itself such endorsement is markedly absent. Consequently, in all the circumstances, the appeal to public opinion could not affect our decision.
[202]There is little I wish to add to what has been said by other members of the Court on the application of section 33. On the question whether a death penalty can be justified by its deterrent effect the statistical and other evidence is inconclusive, as it was bound to be. As the analysis of Chaskalson P shows the statistical evidence comes nowhere near establishing that the death penalty is an effective deterrent against murder. Nor on the other hand can it be shown that it is not a deterrent. As Mr von Lieres pointed out, only those who were not deterred enter the statistics; the number who were deterred cannot be known. In Burns' well-known lines, "What's done we often may compute/But know not what's resisted." The most impressive argument of Mr von Lieres on this aspect of the case was that, statistics aside, the awfulness of the death penalty must in its nature deter some would-be murderers. In the face of the appalling murder rates in this country, he said, we cannot afford to relinquish any possible weapon in the fight against violent crime. That is a powerful argument but, given the cruelty and inhumanity of the death penalty, it is an argument which cannot in the end prevail. It relies essentially on the mere possibility that the death sentence may deter some murderers. That is not a sufficient justification for the continued existence of such an extreme punishment.
[203]I have little to add, too, to what Chaskalson P has said on the element of retribution as an element in punishment. The Attorney-General's argument was that the criminal law including the modes of punishment must adequately reflect the moral outrage felt by society when a vicious and cold-blooded murder is committed. This too I regard as an argument of weight. One can understand in particular the reaction of the families of victims of murderers and the feeling that the culprits "deserve to die". But the choice, as Chaskalson P has pointed out, is not between death penalty on the one hand and the condonation of the murderer's act on the other. The choice is between the death penalty and a long term of imprisonment which might in appropriate cases include life imprisonment in the fullest sense of the term. As a civilised society it is not open to us, in my opinion, to express our moral outrage by executing even the worst of murderers any
