This Practice Note deals with the law relating to conspiracy, which means that at least two people have agreed to commit a crime under the Criminal Law Act 1977. It covers what is meant by statutory conspiracy, what is meant by ‘the agreement’, ‘the course of conduct to be pursued’, ‘if carried out in accordance with their intentions’ and ‘necessarily amount to or involve the commission of an offence’. It then deals with evidential considerations, including the rule that acts and statements of one party to a common purpose may be evidence against the other and the position where there is the acquittal of one of the co-accused. Finally, it covers jurisdictional considerations and sentencing.
