The judicial power of the state is vested in one supreme court, district courts, justice courts, and such other courts as may be provided by law.

(1) The supreme court has appellate jurisdiction and may issue, hear, and determine writs appropriate thereto. It has original jurisdiction to issue, hear, and determine writs of habeas corpus and such other writs as may be provided by law. (2) It has general supervisory control over all other courts. (3) It may make rules governing appellate procedure, practice and procedure for all other courts, admission to the bar and the conduct of its members. Rules of procedure shall be subject to disapproval by the legislature in either of the two sessions following promulgation. (4) Supreme court process shall extend to all parts of the state.

(1) The supreme court consists of one chief justice and four justices, but the legislature may increase the number of justices from four to six. A majority shall join in and pronounce decisions, which must be in writing. (2) A district judge shall be substituted for the chief justice or a justice in the event of disqualification or disability, and the opinion of the district judge sitting with the supreme court shall have the same effect as an opinion of a justice.

(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.

(1) There shall be elected in each county at least one justice of the peace with qualifications, training, and monthly compensation provided by law. There shall be provided such facilities that they may perform their duties in dignified surroundings. (2) Justice courts shall have such original jurisdiction as may be provided by law. They shall not have trial jurisdiction in any criminal case designated a felony except as examining courts. (3) The legislature may provide for additional justices of the peace in each county.

(1) The legislature shall divide the state into judicial districts and provide for the number of judges in each district. Each district shall be formed of compact territory and be bounded by county lines. (2) The legislature may change the number and boundaries of judicial districts and the number of judges in each district, but no change in boundaries or the number of districts or judges therein shall work a removal of any judge from office during the term for which he was elected or appointed. (3) The chief justice may, upon request of the district judge, assign district judges and other judges for temporary service from one district to another, and from one county to another.

(1) All justices and judges shall be paid as provided by law, but salaries shall not be diminished during terms of office. (2) Terms of office shall be eight years for supreme court justices, six years for district court judges, four years for justices of the peace, and as provided by law for other judges.

(1) Supreme court justices and district court judges shall be elected by the qualified electors as provided by law. (2) For any vacancy in the office of supreme court justice or district court judge, the governor shall appoint a replacement from nominees selected in the manner provided by law. If the governor fails to appoint within thirty days after receipt of nominees, the chief justice or acting chief justice shall make the appointment from the same nominees within thirty days of the governor's failure to appoint. Appointments made under this subsection shall be subject to confirmation by the senate, as provided by law. If the appointee is not confirmed, the office shall be vacant and a replacement shall be made under the procedures provided for in this section. The appointee shall serve until the election for the office as provided by law and until a successor is elected and qualified. The person elected or retained at the election shall serve until the expiration of the term for which his predecessor was elected. No appointee, whether confirmed or unconfirmed, shall serve past the term of his predecessor without standing for election. (3) If an incumbent files for election and there is no election contest for the office, the name of the incumbent shall nevertheless be placed on the general election ballot to allow the voters of the state or district to approve or reject him. If an incumbent is rejected, the vacancy in the office for which the election was held shall be filled as provided in subsection (2).

(1) A citizen of the United States who has resided in the state two years immediately before taking office is eligible to the office of supreme court justice or district court judge if admitted to the practice of law in Montana for at least five years prior to the date of appointment or election. Qualifications and methods of selection of judges of other courts shall be provided by law. (2) No supreme court justice or district court judge shall solicit or receive compensation in any form whatever on account of his office, except salary and actual necessary travel expense. (3) Except as otherwise provided in this constitution, no supreme court justice or district court judge shall practice law during his term of office, engage in any other employment for which salary or fee is paid, or hold office in a political party. (4) Supreme court justices shall reside within the state. During his term of office, a district court judge shall reside in the district and a justice of the peace shall reside in the county in which he is elected or appointed. The residency requirement for every other judge must be provided by law.

Any holder of a judicial position forfeits that position by either filing for an elective public office other than a judicial position or absenting himself from the state for more than 60 consecutive days.

(1) The legislature shall create a judicial standards commission consisting of five persons and provide for the appointment thereto of two district judges, one attorney, and two citizens who are neither judges nor attorneys. (2) The commission shall investigate complaints, and make rules implementing this section. It may subpoena witnesses and documents. (3) Upon recommendation of the commission, the supreme court may: (a) Retire any justice or judge for disability that seriously interferes with the performance of his duties and is or may become permanent; or (b) Censure, suspend, or remove any justice or judge for willful misconduct in office, willful and persistent failure to perform his duties, violation of canons of judicial ethics adopted by the supreme court of the state of Montana, or habitual intemperance. (4) The proceedings of the commission are confidential except as provided by statute.
