Joint Criminal Enterprise
11. The law is that where two or more persons carry out a joint criminal enterprise, that is an agreement to carry out a particular criminal activity, each is responsible for the acts of another participant in carrying out that enterprise or activity. This is so regardless of the role taken by a particular participant. The Crown must establish both the existence of a joint criminal enterprise and the participation in it by the accused person.
12. A joint criminal enterprise exists where two or more persons reach an understanding or arrangement amounting to an agreement between them that they will commit a crime. The agreement need not be expressed in words, and its existence may be inferred from all the facts and circumstances surrounding the commission of the offence that are found proved on the evidence.
13. The agreement need not have been reached at any particular time before the crime is committed, provided that at the time of the commission of the crime, the participants have agreed that the crime should be committed by any one or all of them.
14. The circumstances in which two or more persons are participating together in the commission of a particular crime may themselves establish that at some point in time an agreement has been reached between them that the crime should be committed. For example, if two people are at the very same time punching a third person, a jury could infer or conclude that they had agreed to assault that person.
15. It does not matter whether the agreed crime is committed by only one or some of the participants in the joint criminal enterprise, or whether they all played an active part in committing that crime. All of the participants in the enterprise are equally guilty of committing the crime regardless of the actual part played by each in its commission.
16. The Crown must prove beyond reasonable doubt that the crime which was the subject of the joint agreement was in fact committed. It therefore must prove beyond reasonable doubt that each of the essential facts or ingredients, which make up that crime, was committed, regardless of who actually committed them. Further, in respect of a particular accused, the Crown must prove beyond reasonable doubt that he or she was a participant in the commission of that crime as part of a joint criminal enterprise with one or more persons.
