725 ILCS 5/115-17: Clerk; issuance of subpoenas.

It is the duty of the clerk of the court to issue subpoenas, either on the part of the people or of the accused, directed to the sheriff or coroner of any county of this State. An attorney admitted to practice in the State of Illinois, as an officer of the court, may also issue subpoenas in a pending action. A witness who is duly subpoenaed who neglects or refuses to attend any court, under the requisitions of the subpoena, shall be proceeded against and punished for contempt of the court. Attachments against witnesses who live in a different county from that where the subpoena is returnable may be served in the same manner as warrants are directed to be served out of the county from which they issue.
