District courts, formerly known as municipal courts before the passage of Amendment 80 to the Arkansas Constitution, exercise county-wide jurisdiction over misdemeanor and traffic cases. The city courts operate in smaller communities where district courts do not exist and exercise city-wide jurisdiction.

The District Court provides fair, impartial, and timely adjudication of misdemeanor offenses for the City of Greenbrier. The District Court schedules court appearances, issues warrants, and makes decisions on judicial dispositions.
