Doctrine of Official Immunity Law and Legal Definition

Under the doctrine of official immunity, a public official is not liable to members of the public for negligence that is strictly related to the performance of discretionary duties. When public officials perform purely ministerial duties, however, they may be held liable.

The doctrine of official immunity recognizes that society's compelling interest in vigorous and effective administration of public affairs requires that the law protect those individuals who, in the face of imperfect information and limited resources, must daily exercise their best judgment in conducting the public's business.
