Interactive Constitution Essay on Congressional Delegation

Nondelegation. Article I, Section 1 vests all legislative powers in Congress, which means the President and the Supreme Court cannot assert legislative authority. See Youngstown Sheet & Tube Co. v. Sawyer (1952). This marks an important separation of powers between the departments of the federal government. It also has been interpreted to include a principle of nondelegation, that the people’s representatives in Congress must make the law, rather than delegate that power to the executive or judicial branch.

For most of American history, judges and commentators have assumed that Congress cannot “delegate” legislative authority and the Supreme Court has located this rule in Article I, Section 1. See, e.g., Whitman v. American Trucking Associations, Inc. (2001). Individual Justices have opined that the nondelegation doctrine ought to be treated as a serious limitation on Congress’s authority. (For example, see Justice Thomas’s dissent in Whitman.)

While the principle of nondelegation persists, the Supreme Court has allowed a lot of delegation, so long as Congress includes intelligible principles to guide discretion. The Marshall Court ruled that Congress could delegate authority to the federal courts to adopt rules of process, Wayman v. Southard (1825), and to the President to revive trading privileges, Cargo of the Brig Aurora v. United States (1813). Although assuming a nondelegation doctrine, no law was invalidated for this reason in the nineteenth century.

In 1935, the Supreme Court invalidated a congressional delegation of lawmaking authority to private institutions—the only occasion where the Court has invalidated a law under the nondelegation doctrine. A.L.A. Schechter Poultry Corp. v. United States (1935); Panama Refining Co. v. Ryan (1935).

Particularly since the New Deal, Congress often legislates in open-ended terms that give substantial authority to executive branch officials and judges. Since 1935, almost all the Justices on the Supreme Court have either applied the nondelegation doctrine leniently, to allow large-scale delegations accompanied by vague limiting principles, Mistretta v. United States (1989), or have said the doctrine of unconstitutional delegation is not readily enforceable by the courts. (See Justice Scalia’s dissent in Mistretta).

The Court, however, sometimes gives effect to the values undergirding the nondelegation principle through narrow interpretations of statutory delegations. For example, the Supreme Court has overruled agency rules adopted pursuant to congressional delegations, on the ground that the agency is advancing a big change in policy. “We expect Congress to speak clearly if it wishes to assign to an agency decisions of vast ‘economic and political significance.’” Utility Air Regulatory Group v. EPA (2014) (plurality opinion) (quoting FDA v. Brown & Williamson Tobacco Corp. (2000)); see also King v. Burwell (2015).
