About: Nondelegation doctrine

The doctrine of nondelegation (or non-delegation principle) is the theory that one branch of government must not authorize another entity to exercise the power or function which it is constitutionally authorized to exercise itself. It is explicit or implicit in all written constitutions that impose a strict structural separation of powers. It is usually applied in questions of constitutionally improper delegations of powers of any of the three branches of government to either of the other, to the administrative state, or to private entities. Although it is usually constitutional for executive officials to delegate executive powers to executive branch subordinates, there can also be improper delegations of powers within an executive branch.
