Judicial Selection
The governor appoints judges to the Supreme Court of Missouri from a list provided by a judicial nominating commission. After at least one year on the court, the judge may stand for a 12-year term in an unopposed yes/no retention vote at the time of Missouri’s next general election. Judges may stand for additional terms in the same retention process. To fill an interim vacancy, the governor appoints a judge from a list provided by a judicial nominating commission. There are no term limits. The mandatory retirement age is 70.
State Constitution
Missouri has had four state constitutions adopted between 1820 and 1945. As of January 1, 2026, it had 135 amendments. (Data on file with John Dinan, Wake Forest University.)
