AFFIRMATIVE PREGNANT, Pleading. An affirmative allegation, implying some negative, in favor of the adverse party, for example, if to an action of assumpsit, which is barred by the act of limitations of six years, the defendant pleads that be did not undertake &c. within ten years; a replication that he did undertake, &c. within ten years, would be an affirmative pregnant; since it would impliedly admit that the defendant had not promised within six years. As no proper issue could be tendered upon such plea the plaintiff should, for that reason, demur to it. Gould, PI. c. 6 29, 37; Steph. PI. 381; Lawes, Civ. PI. 113; Bac. Ab. Pleas, N 6.
