The Montana Supreme Court is the highest court of the Montana state court system in the U.S. state of Montana. It is established and its powers defined by Article VII of the 1972 Montana Constitution. It is primarily an appellate court which reviews civil and criminal decisions of Montana's trial courts of general jurisdiction and certain specialized legislative courts, only having original jurisdiction in a limited number of actions. The court's Chief Justice and six Associate Justices are elected by non-partisan, popular elections. The Montana Supreme Court meets in the Joseph P. Mazurek Building in Helena, Montana, the state's capital, an international style building completed in 1982 and named in the honor of former Montana Attorney General, Joseph P. Mazurek.HistoryMontana Territorial Supreme CourtOn May 26, 1864, the United States Congress passed the Organic Act, which formed the Montana Territory and established the Territorial Supreme Court.
