Colstrip Energy, LP v. Northwestern Corp.

by
Appellant, a Montana limited partnership which owned an electrical generating plant in Rosebud County, appealed the district court's order denying its motion to vacate the arbitration award ("Final Award") in its dispute with appellee, a Delaware corporation and a regulated public utility conducting business in Montana. At issue was whether the district court abused its discretion when if failed to vacate, modify, or correct the arbitration award. The court held that the district court did not abuse its discretion in denying appellant's motion where Montana's Uniform Arbitration Act, 27-5-311 MCA, did not permit a court to vacate an arbitration award in part; where Montana law was clear that a non-breaching party was still required to prove its damages; where the district court correctly noted in its order confirming the Final Award that the legal precedent on which appellant relied for its request to modify or correct the Final Award applied only to motions to vacate an award; and where the district court correctly determined that it lacked the authority to vacate the Final Award.
