    (3) If the judge determines that it is in the interest of justice that immunity be granted, the judge shall enter an order granting immunity to the witness if the witness appears before the court in the proceeding and testifies truthfully under oath concerning any matter or thing of which the witness knows concerning matters charged in the complaint and warrant or alleged in the petition, as set forth in the prosecuting attorney's application.

    (1) A true copy of the order granting immunity shall be delivered to the witness before he or she answers any questions subsequently asked at the proceeding. The order granting immunity applies until the judge informs the witness that the immunity no longer applies.

    (3) Truthful testimony or other truthful information compelled under the order granting immunity and any information derived directly or indirectly from that truthful testimony or other truthful 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.

    (1) A public official or agency authorized by a statute of this state to issue a subpoena or otherwise compel the testimony of a witness or the production of evidence in an investigation or proceeding authorized by that statute, or authorized to seek a subpoena or compelled testimony or production of evidence from a court, may apply to the court required to issue the subpoena or compel the testimony or production of evidence or otherwise to the circuit court of the county in which the investigation or proceeding is conducted for an order granting immunity to a person who might give testimony or produce evidence concerning the investigation or subject of the proceeding.
