“Secondary parties liable if principal's acts were foreseeable consequences of joint venture”
Two appeals were heard together. In Powell, defendants attacked a police officer and one used a knife unexpectedly. In English, defendants went to attack a victim with wooden posts but one used a knife to kill. Both cases involved secondary parties claiming the principal's use of a knife was unforeseen.
When secondary parties can be liable for crimes committed by the principal that go beyond what was originally contemplated in their joint criminal venture.
The House of Lords established that secondary parties would be liable if the principal's criminal act was within the contemplation of the joint venture as a possible incident of it, judged objectively.
This case established the fundamental framework for joint enterprise liability in English law, setting out the foreseeability test that has been applied in countless subsequent cases. It remains the leading authority on secondary liability and joint enterprise, though some aspects have been refined by later cases like Jogee.
