Duress is a defence at common law and is available where the D is forced to perform the criminal act by someone else. This defence is available where the D has been effectively forced to commit a crime due to a threat of death or serious injury.
It is available to all crimes except murder, attempted murder and accomplice to murder.
The test for duress by threat was laid down in the case of Graham and affirmed in Howe and more recently in Hasan (2005).
The Graham two-part test:
A) was the defendant impelled to act as he did because he feared death or serious injury?
B) If so, did he respond as a sober person of reasonable firmness sharing that characteristic of the D would have?
1) First part of the test Nature and seriousness of the threat:
a) The nature of the threat
b) To whom the threat should be made
c) The offence committed must be connected to the threat
d) The immediacy of the threat
A. The nature of the threat:
This is a subjective test and the threat must be of death or serious injury. The jury is entitled to look at the cumulative effect of the threats on the D and the defence will be available as long as there is a threat of death or serious violence in there.
