Mont. Code Ann. § 27-28-207

Actions under this chapter commenced in the supreme court must be conducted in the same manner as if commenced in the district court, and the clerk of the supreme court has the same authority to issue summonses and other process and to enter orders and judgments as the clerk of the district court has in like cases. All pleadings and the conduct of the trial must be the same as in the district court. If a jury is required to determine an issue of fact, a jury must be drawn and selected from the jury box of Lewis and Clark County and the clerk of the district court of that county shall place the jury box in the custody of the clerk of the supreme court for that purpose.
