This is a plea for the termination of an action for some error committed in bringing or conducting the action. The plaintiff is not permanently barred from brining another action. There can be no demurrer in abatement. A plea in abatement can be considered for the jurisdiction of the court, to the person of the plaintiff, and to that of the defendant. As to the person, the defendant may plead to the person of the plaintiff that there never was any such person. If persons are joined as plaintiffs in an action, the defendant may plead the misjoinder in abatement.
