Can be used for all crimes except for Murder, attempted murder and treason
the defence is based on the fact that the defendant efficiantly has been forced to commit a crime. Must be threatened by death or serious injury
Threat
( Valderama vega ) - threat must be to kill or cause GBH
( Wright ) - threat must be towards the defendant or someone close to the defendant - immediate family
(Cole ) - The threat must be related to the crime - there must be a nexus ( link ) between the threat and offence, must mention committing the specific crime
immediacy = threat must be effective at the moment the crime is committed
threat must be imminent in the sense it is hanging over them ( Hudson v Taylor )
if there is a safe avenue of escape, then the defendant should do something about it ( Gill )
police protection may not always be effective ( Hudson v Taylor )
( Graham ) - sets out the 2 part test
was the defendant compelled to act as they did because they reasonably believed they had good cause to fear injury / death
would a sober person of reasonable firmness sharing the characteristics have responded in the same way
