The Missouri Plan (originally the Missouri Nonpartisan Court Plan, also known as the merit plan, or some variation) is a method for the selection of judges. It originated in Missouri in 1940 and has been adopted by several states of the United States. Similar methods are used in some other countries.
Under the Plan, a non-partisan commission reviews candidates for a judicial vacancy. The commission then sends to the governor a list of candidates considered best qualified. The governor then has sixty days to select a candidate from the list. If the governor does not make a selection within sixty days, the commission makes the selection.
At the general election soonest after the completion of one year's service, the judge must stand in a "retention election". If a majority votes against retention, the judge is removed from office, and the process starts anew. If the majority votes in favor of retention, the judge serves out a full term.
Under the Missouri Nonpartisan Court Plan, a nonpartisan judicial commission reviews applications, interviews candidates and selects a judicial panel. For the Supreme Court and Court of Appeals, the Appellate Judicial Commission makes the selection. It is composed of three lawyers elected by members of the Missouri Bar (the organization of all lawyers licensed in this state), three citizens selected by the governor, and the chief justice, who serves as chair. Each of the three geographic districts of the Court of Appeals must be represented by one lawyer and one citizen member on the Appellate Judicial Commission.
Each of the circuit courts in Clay, Greene, Jackson, Platte, and St. Louis Counties, and the city of St. Louis has its own circuit judicial commission. These commissions are composed of the chief judge of the court of appeals district in which the circuit is located, plus two lawyers elected by the bar and two citizens selected by the governor. All of the lawyers and citizens must live within the circuit for which they serve the judicial commission.
In line with other reforms urged during the Progressive Era, legal scholars put forth ideas in the first decades of the 1900s to reduce or remove the role of politics in the selection of judges, particularly circuit judges with responsibilities over the day-to-day work of the courts. An example of this advocacy is the merit selection program urged by Albert M. Kales in his work Unpopular Government in the United States (1914).
