The name of an English court which was established on the breaking up of the aula regis, for the determination of pleas merely civil. It was at first ambulatory, but was afterwards located. This jurisdiction is founded on original write issuing out of chancery, in the cases of common persons. But when an attorney or person belonging to the court, is plaintiff, he sues by writs, of privilege, and is sued by bill, which is in the nature of a petition; both which originate in the common pleas. See Bench; Banc.

Legal Definition
The English court of common pleas was one of the four superior courts at Westminster, and existed up to the passing of the judicature acts. It was also styled the "Common Bench." It was one of the courts derived from the breaking up of the aula regis, and had exclusive jurisdiction of all real actions and of communia placita, or common pleas, i. e., between subject and subject. It was presided over by a chief justice with four puisne judges. Appeals lay anciently to the king's bench, but afterwards to the exchequer chamber. See 3 Bl. Comm. 37, et seq. In American law. The name sometimes given to a court of original and general jurisdiction for the trial of issues of fact and law according to the principles of the common law. See Moore v. Barry, 30 S. C. 530, 9 S. E. 589, 4 In R. A. 294.
