Michigan Compiled Laws, Chapters 760 to 777 Code of Criminal Procedure § 767.19b

Sec. 19b. (1) A true copy of the order granting immunity shall be delivered to the witness before he or she answers any questions before the grand jury.

(2) Truthful testimony or other information compelled under the order granting immunity and any information derived directly or indirectly from that truthful testimony or other information shall not be used against the witness in a criminal case, except for impeachment purposes or in a prosecution for perjury or otherwise failing to comply with the order.

(3) All questions asked of the witness and his or her answers shall be transcribed. If a witness who has been granted immunity subsequently alleges that he or she is being prosecuted for an offense in violation of the grant of immunity, a true copy of the transcript, duly certified by an officer authorized to administer oaths, shall be delivered to the witness as soon as practicable.

(4) The order granting immunity shall continue in effect until the judge who summoned the jury or his or her successor, in his or her discretion and upon the prosecuting attorney's application, enters an order terminating the order granting immunity and informs the witness of the order of termination.
