Maryland’s Circuit Courts are the general trial courts with broad jurisdiction. They handle the more serious criminal cases (felonies and other major offenses) and larger civil matters, and they also oversee cases in areas like family law, probate, and equity. A key role they play is reviewing decisions from the District Courts—their appellate function for many District Court rulings. They aren’t the place where licenses are issued (that duty sits with the Clerk of the Circuit Court), and they aren’t primarily described as the body that handles appellate review of county ordinances. The best summary of their function is that they handle major criminal and civil cases and hear appeals from the District Courts.
