Montana Title 3. Judiciary, Courts § 3-15-503. Drawing--how conducted

(1)(a) If the drawing of jurors is conducted by means of a jury box, the jury commissioner shall place the box on a rod so that it may readily revolve. The box must be revolved a sufficient number of times to ensure that the numbered slips in it become thoroughly mixed. The jury commissioner shall then draw from the box, one at a time, as many of the numbered slips as are ordered by the court.

(b) If the drawing of jurors is conducted by means of a computerized database, it must be conducted by use of a computerized random selection process that the judges of the district court of the county have approved in writing as satisfactorily fulfilling the requirements for the drawing of trial juries.
