in law, the transfer of authority by one person or group to another person or group. For example, the U.S. Congress may create government agencies to which it delegates authority to promulgate and enforce regulations pursuant to law. More specifically, in U.S. constitutional law, delegation of powers refers to the different powers granted respectively to each of three branches of government—executive, legislative, and judicial. Exercise by one branch of a power delegated to another violates the separation of powers provided for in the Constitution; i.e., it is unconstitutional. Constitutional powers may be classified as enumerated, implied, inherent, resulting, or sovereign—designations that explain the nature of a given power, its origin, and its scope of influence.
