If, somehow, Section 301 does authorize this action, it would violate the constitutional nondelegation doctrine, which limits delegation of legislative power to the executive. Tariffs are a specifically enumerated congressional power. While the Supreme Court’s nondelegation precedent is far from completely clear, last year’s decision in FCC v. Consumers’ Research held that delegations of the power to impose taxes and other financial levies must have a clear “floor” and “ceiling” and that “[t]he guidance needed is greater when an agency action will affect the entire national economy than when it addresses a narrow, technical issue” [quotation omitted]. There is no meaningful floor or ceiling under the administration’s approach to Section 301. And the power claimed is clearly one that massively affects the “entire national economy.”
