BAR, or Barre, (Latin barra, and in French barre), in a legal sense, is a plea or peremptory exception of a defendant, sufficient to destroy the plaintiff's action. And it is divided into bar to common intentment, and bar special; bar temporary, and perpetual. Bar to a common intentment is an ordinary or general bar, which usually disableth the declaration of the plaintiff; bar special is that which is more than ordinary, and falls out upon some special circumstance of the fact as to the case in hand. Bar temporary is such a bar as is good for the present, but may afterwards fail; and bar perpetual is that which overthrows the action of the plaintiff for ever.
