A plaintiff or complainant. In a civil or private action the plaintiff was often called by the Romans “petitor;” ina public action (causa publica) he was called “accusator.” The defendant was called “reus,” both in private and public causes; this term, however, according to Cicero, (Ve Grat. ii. 43,) might signify either party, as indeed we might conclude from the word itself. In a private action, the defendant was often called “adversarius,” but either party might be calied so. Also, the term is used of a party who, for the time being, sustains the burden of proof, or has the initiative in the suit. In old Huropean law.
