The Supreme Court held on February 20, 2026 that the International Emergency Economic Powers Act does not authorize the president to impose tariffs, deciding Learning Resources, Inc. v. Trump 6-3 in an opinion by Chief Justice John Roberts. Per the Court's holding, the 1977 emergency-economics statute contains no tariff power, and the decision vacated the sweeping duties imposed under the April 2025 emergency declaration.

What did the ruling actually strike down?
The case consolidated challenges to the tariffs imposed under IEEPA beginning in April 2025, including the global baseline duties and country-specific rates announced in what the administration called its liberation-day action. Importers including Learning Resources and the vendors in the companion case, Trump v. V.O.S. Selections, argued the statute authorizes regulating economic transactions during a declared emergency, not imposing taxes. The Court agreed 6-3: per the opinion, major tariff power rests with Congress, and IEEPA's grant of authority to "regulate" importation cannot be stretched to levy duties.

How much revenue and policy does this unwind?
IEEPA tariffs became the centerpiece of the administration's trade and revenue strategy, collected by Customs and Border Protection on billions of dollars of imports over ten months. Per Congressional Research Service analysis of the ruling, the decision makes it unlawful for CBP to continue collecting IEEPA-based tariffs, and the administration subsequently moved to terminate them. The ruling does not touch tariffs imposed under other authorities — Section 232 national-security duties, Section 301 China tariffs and Section 201 safeguards all rest on separate statutes and remain in force.
What happens to the money already collected?
Refund mechanics were unresolved when the Court ruled, since the decision vacated and remanded rather than dictating a repayment scheme. Importers who paid under protest have documented claims; the scale runs to tens of billions of dollars per CRS and court filings, making refunds one of the largest administrative reversals in recent trade policy. The remand leaves lower courts to sort liability, interest and timing, a process expected to run through 2026.
What does this change?
The immediate change is institutional: the administration lost its fastest tariff instrument, and per the ruling any replacement duties must come from Congress or from narrower statutory authorities that carry investigation timelines and product limits. Expect heavy pressure on lawmakers to codify a replacement, new Section 232 investigations to fill the gap, and continued litigation over refunds. The longer-term change is doctrinal — the second major decision in as many terms policing the boundary of delegated emergency powers, and a signal that the Court's majority reads statutory grants narrowly when they carry trillion-dollar economic effect.
