Learning Resources, Inc. v. Trump

Background

President Trump declared national emergencies in 2025 to address illegal drug inflows and large trade deficits and invoked IEEPA. He imposed drug‑related tariffs—25% on most Canadian and Mexican imports and initial duties on Chinese goods—and broad reciprocal tariffs starting at 10% on all imports, later raising Chinese rates to very high levels. Two small businesses sued in D.C.; five small businesses and 12 States sued in the Court of International Trade. The lower courts split, and the cases reached this Court.

Reasoning

The Court held that IEEPA does not authorize tariffs. The Chief Justice’s opinion emphasized that tariffs are essentially part of Congress’s taxing power under Article I and that Congress normally delegates tariff authority with explicit words and limits. Applying major‑questions reasoning, the Court said an extraordinary grant to tax imports would require clear authorization, which IEEPA’s general power to “regulate . . . importation” does not provide. The Court remanded and affirmed the two consolidated cases accordingly.

Real world impact

The decision prevents Presidents from using IEEPA as the legal basis for the challenged tariffs and orders dismissal or affirmance in the consolidated cases. It affects small businesses, States, importers, and foreign trading partners tied to those tariffs; the opinion records that projected effects cited by the Government included large deficit changes and deal values. The ruling directs future tariff policymaking toward clearer congressional authorizations or other trade statutes.

Dissents or concurrances

Justices divided. A plurality applied the major‑questions standard; three Justices agreed on the outcome using ordinary interpretation; two Justices dissented, arguing history and statute permit tariffs; two wrote separate concurrences.
