(a) For Attendance of Witnesses -- Form -- Issuance. A subpoena shall be issued either by the court or by the clerk of the court or by counsel whose appearance has been entered in the particular case in which the subpoena is sought. It shall state the name of the court and the title, if any, of the proceeding, and shall command each person to whom it is directed to attend and give testimony at the time and place specified therein. The court or clerk shall issue a subpoena signed and sealed but otherwise in blank to a party requesting it, who shall fill in the blanks before it is served. (b) For Production of Documentary Evidence and of Objects. Upon order of the court which may be issued ex parte, a subpoena may also command the person to whom it is directed to produce the books, papers, documents, photographs, or other objects designated therein. The court on motion made promptly may quash or modify the subpoena if compliance would be unreasonable or oppressive. The court may direct that books, papers, documents, photographs, or objects designated in the subpoena be produced before the court at a time prior to the trial or prior to the time when they are to be offered in evidence and may upon their production permit the books, papers, documents, photographs, or objects or portions thereof to be inspected by the parties and their attorneys. (c) Service. Unless service is admitted or waived, a subpoena may be served by any peace officer or any other person who is not a party and who is not less than eighteen years of age. Service of a subpoena may be made by delivering a copy thereof to the person named. Service is also valid if the person named has signed a written admission or waiver of personal service. (d) Contempt. Failure by any person without adequate excuse to obey a subpoena may be deemed a contempt of the court from which the subpoena issued.
