(a) Any justice or judge may qualify for retention by a vote of the electors in the general election next preceding the expiration of the justice’s or judge’s term in the manner prescribed by law. If a justice or judge is ineligible or fails to qualify for retention, a vacancy shall exist in that office upon the expiration of the term being served by the justice or judge. When a justice or judge so qualifies, the ballot shall read substantially as follows: “Shall Justice (or Judge)   (name of justice or judge)   of the   (name of the court)   be retained in office?” If a majority of the qualified electors voting within the territorial jurisdiction of the court vote to retain, the justice or judge shall be retained for a term of six years. The term of the justice or judge retained shall commence on the first Tuesday after the first Monday in January following the general election. If a majority of the qualified electors voting within the territorial jurisdiction of the court vote to not retain, a vacancy shall exist in that office upon the expiration of the term being served by the justice or judge.

(b)(1) The election of circuit judges shall be preserved notwithstanding the provisions of subsection (a) unless a majority of those voting in the jurisdiction of that circuit approves a local option to select circuit judges by merit selection and retention rather than by election. The election of circuit judges shall be by a vote of the qualified electors within the territorial jurisdiction of the court.
