Mispleading

Pleading incorrectly or omitting anything in pleading which ls essential to the support or defense of an action, ls so called; as in the case of a plaintiff not merely stating his title in a defective manner, but setting forth a title which is essentially defective in itself; or if, to an action of debt, the defendant pleads "not guilty" instead of nil debet.
