Circuit Courts are the highest common law and equity courts of record exercising original jurisdiction within Maryland. Each has full common law and equity powers and jurisdiction in all civil and criminal cases within its county or counties, and all the additional powers and jurisdiction conferred by the Maryland Constitution and by law, except where jurisdiction has been limited or conferred exclusively upon another tribunal by law. The Circuit Courts are trial courts of general jurisdiction. Their jurisdiction is very broad but generally covers major civil cases and more serious criminal matters. Circuit Courts also may decide appeals from the District Court and certain administrative agencies. Cases can be heard by a jury when the amount in controversy is over $15,000. Juries are limited to the Circuit Courts.
