In English Law, an attorney who has an exclusive right of argument in all the superior courts. A barrister is a counselor who is learned in law and who has been admitted to plead at the bar. A barrister drafts the pleadings in all cases, with the exception of the simplest ones. Distinguished from an attorney, which is an English lawyer who conducts matters out of court, a barrister engages in the actual argument of cases or the conduct of the trial.
