# Major Questions Doctrine The **major questions doctrine** holds that when an agency, and now the President, claims authority over a question of vast economic or political significance, courts will not infer that authority from ambiguous or peripheral statutory text. Congress must speak clearly. It is a **clear-statement rule**, not a constitutional holding: Congress may grant the power, but has to do so unmistakably. That is what makes it the working substitute for the stalled [[Nondelegation Doctrine]]. ## The case line The idea existed long before the name: - *MCI v. AT&T* (1994): the FCC's power to "modify" tariff filing did not include abolishing it. - *FDA v. Brown & Williamson* (2000): the FDA could not regulate tobacco under its drug and device authority. - *Utility Air Regulatory Group v. EPA* (2014): the Court "expect[s] Congress to speak clearly" before assigning an agency decisions of vast economic and political significance. - *King v. Burwell* (2015): the Court used the logic to deny the IRS [[Chevron deference]], then upheld the ACA subsidies on its own reading. The doctrine was named and consolidated between 2021 and 2023: - *Alabama Association of Realtors v. HHS* (2021): the CDC eviction moratorium. - *NFIB v. OSHA* (2022): the vaccine-or-test mandate. - [[West Virginia v. EPA]] (2022): the Clean Power Plan's generation shifting. Chief Justice [[John Roberts]] used the phrase "major questions doctrine" as the Court's own label for the first time. - *Biden v. Nebraska* (2023): student-loan cancellation. Justice [[Amy Coney Barrett]]'s concurrence recast the doctrine as ordinary linguistic context, not a thumb on the scale. ## After Chevron [[Loper Bright Enterprises v. Raimondo]] (2024) ended Chevron deference, so courts now decide every statutory question de novo. That arguably makes the major questions doctrine redundant in ordinary cases, but it survives as an added burden on claims of large power. ## The presidential test case [[Learning Resources v. Trump]] (February 20, 2026) moved the doctrine from agencies to the President. The Court held 6–3 that the [[International Emergency Economic Powers Act]] does not authorize tariffs. But only three justices (Roberts, [[Neil Gorsuch]] and Barrett) rested on the major questions doctrine. Justices [[Elena Kagan]], Sotomayor and Jackson reached the same result on the statute's text alone. Justice [[Brett Kavanaugh]], joined by Thomas and Alito, dissented. So the doctrine's biggest application commanded three votes, not five. After the ruling the administration shifted to 15% tariffs under Section 122 of the Trade Act of 1974. ## The critique The standard objection is asymmetry. Every landmark application before 2026 struck down a program of a Democratic administration: the eviction moratorium, the vaccine rule, the Clean Power Plan, and loan relief. In her *West Virginia* dissent, Kagan wrote that special canons like this one "magically appear as get-out-of-text-free cards." *Learning Resources* is the first major counterexample, and the thin plurality behind the doctrine there is the best measure of how durable it is. ## See also - [[Nondelegation Doctrine]] · [[Emergency Powers]] · [[Emergency Powers Crosswalk]] - [[West Virginia v.
