is the body of law governing administrative agencies- -that is, those agencies created by Congress or state legislatures, such as the Social Security Administration, state Unemployment Insurance Boards, state Welfare Commissions and the Occupational Safety and Health Administration. The authority these agencies possess is delegated to them by the bodies which created them; the Social Security Administration's power comes from Congress.
Administrative agencies administer law through the creation and enforcement of regulations; most of these regulations pertain to providing some type of benefit to applicants. Frequently, an applicant objects to an agency's decision to deny, limit or terminate the benefits provided and seeks to have the decision reviewed. This review is called an administrative hearing and is held before an administrative law judge (A.L.J.).
