In the USA, this is one of the initial documents issued in a civil suit; giving the defendant notice of the claim and an opportunity to defend it. The summons also gives the court which issues it the authority to dispose of the matter. In Canadian criminal law, this is the document used by the police to compel an accused to attend court to answer the charges. It does not involve the arrest of the accused and is used where the police, either by the relatively less serious nature of the crime or because of the standing of the accused in the community, do not believe that arrest is necessary to ensure the attendance of the accused at court.
