Administrative law governs the activities of administrative agencies of government, including rule-making, adjudication or the enforcement of regulations. At the federal level, administrative law emcompasses the U.S. Congress. At the state level, it encompasses state representatives. And at the local town council and county commissions level, they can also make rules. Administrative law also includes the enforcement of these regulations by bringing actions against violators.
Attorneys practice administrative law on behalf of both the government and private clients. For example, an administrative law lawyer may help a client navigate administrative procedures in order to make sure they succeed in making a certain claim to an agency. They might work with a client to bring a formal court proceeding after they've exhausted administrative remedies. An administrative law attorney might also represent a private client in an action to challenge the constitutionality of a regulation or the legislative authority for a rule or regulation.
