Wyoming's highest court is the Supreme Court of Wyoming, with five justices presiding over appeals from the state's lower courts. Wyoming is unusual in that it does not have an intermediate appellate court, like most states. This is largely attributable to the state's population and correspondingly lower caseload. Appeals from the state district courts go directly to the Wyoming Supreme Court. Wyoming also has state circuit courts (formerly county courts), of limited jurisdiction, which handle certain types of cases, such as civil claims with lower dollar amounts, misdemeanor criminal offenses, and felony arraignments. Circuit court judges also commonly hear small claims cases as well.
Before 1972, Wyoming judges were selected by popular vote on a nonpartisan ballot. This earlier system was criticized by the state bar who called for the adoption of the Missouri Plan, a system designed to balance judiciary independence with judiciary accountability. In 1972, an amendment to Article 5 of the Wyoming Constitution, which incorporated a modified version of the plan, was adopted by the voters. Since the adoption of the amendment, all state court judges in Wyoming are nominated by the Judicial Nominating Commission and appointed by the Governor. They are then subject to a retention vote by the electorate one year after appointment.
