Mont. Code § 75-1-312
In the discharge of its duties, the council may hold hearings, administer oaths, issue subpoenas, compel the attendance of witnesses and the production of any papers, books, accounts, documents, and testimony, and cause depositions of witnesses to be taken in the manner prescribed by law for taking depositions in civil actions in the district court. In case of disobedience on the part of a person to comply with a subpoena issued on behalf of the council or a committee of the council or of the refusal of a witness to testify on any matters regarding which the witness may be lawfully interrogated, it is the duty of the district court of any county or the judge of the district court, on application of the council, to compel obedience by proceedings for contempt as in the case of disobedience of the requirements of a subpoena issued from the court on a refusal to testify in the court.
