(1) The district court has original jurisdiction in all criminal cases amounting to felony and all civil matters and cases at law and in equity. It may issue all writs appropriate to its jurisdiction. It shall have the power of naturalization and such additional jurisdiction as may be delegated by the laws of the United States or the state of Montana. Its process shall extend to all parts of the state.

(2) The district court shall hear appeals from inferior courts as trials anew unless otherwise provided by law. The legislature may provide for direct review by the district court of decisions of administrative agencies.

(3) Other courts may have jurisdiction of criminal cases not amounting to felony and such jurisdiction concurrent with that of the district court as may be provided by law.
