Duress is a common law defence that applies where a person commits a crime because they were acting under a threat of death or serious injury - D is forced to break the law because of the threat but he must have acted as a reasonable man
The test for duress was set out in the case of Hasan
Threat to cause death or serious injury against D/immediate family/someone they are close to
D must act reasonably in the light of the threats and be judged objectively
The threats relate closely to the crime - causal nexus
No evasive action D could have taken
Defence fails if D voluntarily associates themselves
1. The threat must be of death to the D, immediate family or someone they were close to - this is seen in the case of Valderrama-Vega
2. D must act reasonably in the light of the threats and be judged objectively - Seen in the case of Graham
Subjective test: Was he forced to act as he reasonably believed he has cause to fear death or serious injury?
Objective test: Would the sober man of reasonable firmness, having D's characteristics have acted in the same way? *MUST APPLY IN PQ*
3. Causal Nexus - Seen in the case of Cole
There must be a direct link between the threat and the final crime committed by the D otherwise the defence will fail
4. Timing of the threat - Seen in the case of Gill
Could D have taken any evasive action, were they in a situation where they have 'no safe avenue of escape?'
5. Voluntary association - Seen in the case of Hasan
Did D voluntarily associate themselves with the threat? Did he foresee or ought to have reasonably foreseen the risk of being subjected to threats or violence
Duress by circumstance:
Threat comes by a circumstance, not a person
1. He reasonably believed he has good cause to fear death or serious injury, and;
2. A sober man of reasonable firmness, sharing some of D's characteristics would have reacted in the same way
