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.
