Accardi Doctrine Law and Legal Definition

Accardi doctrine is an agency which must abide by its own regulations. This doctrine is named after the Supreme Court decision from which the doctrine was developed, US ex rel Accardi. The Accardi doctrine provides that when an agency fails to follow its own procedures or regulations, that agency's actions are generally invalid. Therefore, an agency's failure to afford an individual procedural safeguards required under its own regulations may result in the invalidation of the ultimate administrative determination.
