On February 20th 2026, the Supreme Court of the United States held that the International Emergency Powers Act (IEEPA) doesn’t authorizes the President to impose tariffs in peacetime emergencies. The ruling in Learning Resources, Inc v. Trump marks a significant recalibration of executive economic authority.

The Court reaffirmed Congress’s constitutional control over tariff policy, limited the use of emergency powers as a structural trade tool, and expanded the reach of the “major questions doctrine” into the geoeconomic domain.

While the immediate impact concerns specific tariffs imposed under IEEPA, the broader consequences extend also to the balance of power between Congress and the Presidency, the architecture of the US emergency economic governance, and the credibility of US trade diplomacy.

This is not a ruling against tariffs per se but a ruling against tariff-making by executive emergency decree with clear congressional authorization.
