Montana Title 46. Criminal Procedure § 46-4-305. Self-incrimination--immunity

(1) No person subpoenaed to give testimony pursuant to this part may be required to make a statement or to produce evidence that may be personally incriminating.

(2) The prosecutor may, with the approval of the judge who authorized the issuance of the subpoena, grant a person subpoenaed immunity from the use of any compelled testimony or evidence or any information directly or indirectly derived from the testimony or evidence against that person in a criminal prosecution.

(3) Nothing in this part prohibits a prosecutor from granting immunity from prosecution for or on account of any transaction, matter, or thing concerning which a witness is compelled to testify if the prosecutor determines, in the prosecutor's sole discretion, that the best interest of justice would be served by granting immunity.

(4) After being granted immunity, no person may be excused from testifying on the grounds that the testimony may be personally incriminating. Immunity may not extend to prosecution or punishment for false statements given pursuant to the subpoena.

(5) Nothing in this part requires a witness to divulge the contents of a privileged communication unless the privilege is waived as provided by law.
