Nondelegation Doctrine - United States

United States

In Federal Government of the United States, the nondelegation doctrine is the principle that the Congress of the United States, being vested with "all legislative powers" by Article One, Section 1 of the United States Constitution, cannot delegate that power to anyone else. However, the Supreme Court ruled in In J.W. Hampton, Jr., & Co. v. United States (1928) that Congressional delegation of legislative authority is an implied power of Congress that is constitutional so long as Congress provides an "intelligible principle" to guide the executive branch: "'In determining what Congress may do in seeking assistance from another branch, the extent and character of that assistance must be fixed according to common sense and the inherent necessities of the government co-ordination.' So long as Congress 'shall lay down by legislative act an intelligible principle to which the person or body authorized to is directed to conform, such legislative action is not a forbidden delegation of legislative power.'"

For example, the Food and Drug Administration (FDA) is an agency in the Executive branch created by Congress with the power to regulate food and drugs in the United States. Congress has given the FDA a broad mandate to ensure the safety of the public and prevent false advertising, but it is up to the agency to assess risks and announce prohibitions on harmful additives, and to determine the process by which actions will be brought based on the same. Similarly, the Internal Revenue Service has been given the responsibility of collecting taxes that are assessed under the Internal Revenue Code. Although Congress has determined the amount of the tax to be assessed, it has delegated to the IRS the authority to determine how such taxes are to be collected. Administrative agencies like these are sometimes referred to as the Fourth Branch of government.
