administrative law, Law regulating the powers, procedures, and acts of public administration. It applies to all public officials and public agencies. As distinguished from legislative and judicial authority, administrative authority entails the power to issue rules and regulations based on statutes, grant licenses and permits to facilitate the conduct of government business, initiate investigations of and provide remedies for complaints or problems, and issue orders directing parties to conform to governing statutes or rules. An administrative-law judge is a government official with quasi-judicial powers, including the authority to conduct hearings, make findings of fact, and recommend resolution of disputes concerning the agency’s actions.
