Non Assumpsit

Non assumpsit (he did not promise), a plea by way of traverse, which occurred in the action of assumpsit or promises. This plea operated as a denial in point of fact of the existence of any express promise to the effect alleged in the declaration, or of the matters of fact from which the promise alleged would be implied by law: see Steph. Plead., 7th ed. 154, 160. See, too, as to the effect of the plea, Bullen and Leake's Prec. of Pleadings.
