Common purpose
The doctrine of common purpose, common design, joint enterprise, joint criminal enterprise or parasitic accessory liability is a common law legal doctrine that imputes criminal liability to the participants in a criminal enterprise for all reasonable results from that enterprise. The common purpose doctrine was established in English law, and later adopted in other common-law jurisdictions including Scotland, Ireland, Australia, Trinidad and Tobago, the Solomon Islands, Texas, the International Criminal Court, and the International Criminal Tribunal for the former Yugoslavia.
