Administrative law
Administrative law is a division of law governing the activities of executive branch agencies of government. Administrative law includes executive branch rule making (executive branch rules are generally referred to as "regulations"), adjudication, and the enforcement of laws. Administrative law is considered a branch of public law. Administrative law deals with the decision-making of such administrative units of government that are part of the executive branch in such areas as international trade, manufacturing, the environment, taxation, broadcasting, immigration, and transport. Administrative law expanded greatly during the 20th century, as legislative bodies worldwide created more government agencies to regulate the social, economic and political spheres of human interaction.
