Definition

A criminal-law concept describing conduct, procedure, or legal consequence defined by governing offense or rule elements. It applies only when the legally specified conditions for its use or enforcement are satisfied. It does not apply where required elements or conditions are absent. It materially affects charging, adjudication, detention, or sanction decisions in practice.

Definition

A litigation doctrine under which a defendant, while not necessarily disputing the prosecution's or plaintiff's prima facie factual allegations, introduces new facts or legal grounds (such as justification or excuse) that, if proved, negate criminal or civil liability; the allocation of burdens of production and persuasion for those elements varies by jurisdiction and statute.
