# Nondelegation Doctrine The **nondelegation doctrine** holds that Congress may not hand its legislative power to another branch. Article I vests "all legislative Powers herein granted" in Congress. In practice the Supreme Court has required only that a delegation supply an **"intelligible principle"** to guide the delegate, a standard it announced in *J.W. Hampton Jr. & Co. v. United States* (1928). That test is so permissive that the Court has struck down federal statutes on nondelegation grounds only twice, both in 1935: - *Panama Refining Co. v. Ryan*, over the "hot oil" provision of the National Industrial Recovery Act. - [[Schechter Poultry v. United States]], over the NIRA's industry codes, which Justice Cardozo called "delegation running riot." Since then the Court has upheld everything put in front of it. The high-water mark of deference is *Whitman v. American Trucking Associations* (2001), where Justice Scalia upheld the Clean Air Act's instruction to set air standards "requisite to protect the public health." ## The revival that stalled [[Gundy v. United States]] (2019) upheld a sex-offender registration delegation 5–3 with Justice Kavanaugh not participating. But Justice Alito concurred only in the judgment and said he would reconsider the doctrine with a full Court. Justice [[Neil Gorsuch]]'s dissent, joined by Chief Justice [[John Roberts]] and Justice [[Clarence Thomas]], proposed replacing the intelligible-principle test: Congress must make the policy decisions itself and may leave only the details to others. Counting Alito and Kavanaugh, five justices appeared ready to tighten the test. It didn't happen. In [[FCC v. Consumers' Research]] (June 27, 2025) the Court upheld the Universal Service Fund 6–3. Justice [[Elena Kagan]] wrote for the majority and applied the intelligible-principle test unchanged. Gorsuch dissented again, joined by Thomas and Alito. [[Brett Kavanaugh]]'s concurrence explains why the revival stalled. Delegations to independent agencies, he wrote, are more suspect than delegations to the President, and the Court now has other tools for policing broad delegations: the [[Major Questions Doctrine]] and the end of [[Chevron deference]] in [[Loper Bright Enterprises v. Raimondo]] (2024). ## Where the pressure went The doctrine now works mostly by proxy. Rather than void a statute, the Court reads it narrowly and demands clear authorization for anything large. Emergency statutes are the hardest case. A standby authority that activates on the President's own declaration comes close to letting the delegate decide when the delegation applies, and the broadest of them offer little more guidance than a phrase like "unusual and extraordinary threat." The tariff challenge in [[Learning Resources v. Trump]] (February 2026) was resolved on statutory grounds without reaching nondelegation. ## Why it matters to this vault Nondelegation is the constitutional core of the campaign against the [[Administrative State]]. It is also in tension with that campaign's other half. Kavanaugh's preference for delegations to the President lines up with the [[Unitary Executive Theory]], and after [[Trump v. Slaughter]] (2026) made commissioners removable at will, the distinction between "independent agency" and "President" has largely collapsed. A doctrine meant to return power to Congress is now more likely to be applied in ways that shift it toward the White House. ## See also - [[Major Questions Doctrine]] · [[Emergency Powers]] · [[Emergency Powers Crosswalk]] - [[Schechter Poultry v.
