The defendants appealed against their convictions for murder, saying that their defences of duress had been wrongly disallowed.
Held: Duress is not a defence available on a charge of murder. When a defence of duress is raised, the test is whether the threat was so serious as would cause a reasonable man in the same situation to behave in the same way.
Lord MacKay of Clashfern said: ‘It seems to me plain that the reason that it was for so long stated by writers of authority that the defence of duress was not available in a charge of murder was because of the supreme importance that the law afforded to the protection of human life and that it seemed repugnant that the law should recognise in any individual in any circumstances, however extreme, the right to choose that one innocent person should be killed rather than another. In my opinion, that is the question which we still must face. Is it right that the law should confer this right in any circumstances, however extreme?’
Lord Hailsham said: ‘This brings me back to the question of principle. I begin by affirming that, while there can never be a direct correspondence between law and morality, an attempt to divorce the two entirely is and has always proved to be, doomed to failure, and in the present case, the overriding objects of the criminal law must be to protect innocent lives and to set a standard of conduct which ordinary men and women are expected to observe if they are to avoid criminal responsibility . . Other considerations necessarily arise where the choice is between the threat of death or a fortiori of serious injury and deliberately taking an innocent life. In such a case a reasonable man might reflect that one innocent human life is at least as valuable as his own or that of his loved one. In such a case a man cannot claim he is choosing the lesser of two evils. Instead he is embracing the cognate but morally disreputable principle that the end justifies the means . . It may well be thought that the loss of a clear right to a defence justifying or excusing the deliberate taking of an innocent life in order to emphasise to all the sanctity of a human life is not an excessive price to pay in the light of these mechanisms’.
He continued: ‘There is of course an obvious distinction between duress and necessity as potential defences: duress arises from the wrongful threats or violence of another human being and necessity arises from any other objective dangers threatening the accused. This, however, is a distinction without a relevant difference, since on this view of duress it is only that species of the genus of necessity which is caused by wrongful threats. I cannot see that there is any way in which a person of ordinary fortitude can be excused from the one type of pressure on his will rather than the other.’
