Alternative Pleading

Definition from Nolo’s Plain-English Law Dictionary

A legal fiction in which a pleader alleges two or more legal claims which are inconsistent with each other. For example, someone hurt in an accident can plead that the other party was negligent or ran into him intentionally. Or in a criminal trial, a defendant may plead not guilty and not guilty by reason of insanity (in which there is the implied admission that the defendant committed the act). (See also: pleading)
