noun | \ di-ˈmər-ər \ | de·mur·rer
  1. : a plea in response to an allegation (as in a complaint or indictment) that admits its truth but also asserts that it is not sufficient as a cause of action — compare confession and avoidance

    Note: Demurrers are no longer used in federal civil or criminal procedure but are still used in some states. General demurrers are replaced in the Federal Rules of Civil Procedure by motions to dismiss for failure to state a claim on which relief may be granted. Special demurrers are replaced by motions for a more definite statement. In the Federal Rules of Criminal Procedure, a motion to dismiss or to grant appropriate relief takes the place of a demurrer. Demurrers are sometimes used to question a court's jurisdiction.
