Supreme Court Strikes Down Trump-Era Tariffs in Landmark Ruling

In a significant decision handed down on February 20, 2026, the Supreme Court ruled against the Trump administration’s leverage of the International Emergency Economic Powers Act (IEEPA) to impose tariffs. The 6-3 decision, stemming from the consolidated cases of Learning Resources, Inc. V. Trump and Trump v. V.O.S. Selections, Inc., effectively limits the President’s authority to enact tariffs without explicit congressional authorization.

The Core of the Dispute: IEEPA and Presidential Power

The case centered on whether IEEPA, a law granting the President broad powers to regulate commerce during national emergencies, authorized the tariffs imposed by President Trump under a series of emergency declarations. The plaintiffs, including slight businesses and states, argued that tariffs – essentially taxes on imports – required a clearer congressional mandate than the language of IEEPA provided. The Court agreed, finding that the statute did not authorize the President to impose tariffs. SCOTUSblog

The Court’s Reasoning: Tariffs as Taxation

Chief Justice John Roberts, delivering the opinion for parts of the Court, emphasized that tariffs function as taxes and the power to tax resides primarily with Congress. The Court found that the wording of IEEPA, specifically the verb “regulate” in relation to “importation,” was insufficient justification for imposing tariffs. As Chief Justice Roberts wrote, “Those words cannot bear such weight.” Wikipedia

Justice Elena Kagan, in a concurring opinion joined by Justices Sonia Sotomayor and Ketanji Brown Jackson, highlighted the numerous actions a President can take under IEEPA – “99 actions” – and argued that allowing “regulate…importation” to mean “impose tariffs” would make it an outlier. She noted that none of the other actions authorized by IEEPA involve raising revenue. Wikipedia

Dissenting Opinions and the “Major Questions Doctrine”

The decision wasn’t entirely unified. Justice Brett Kavanaugh, joined by Justices Clarence Thomas and Samuel Alito, authored a lengthy dissent arguing for broader presidential authority on tariffs. Justice Thomas also penned a separate dissent supporting expansive tariff powers for the President. SCOTUSblog

A point of contention within the majority was the application of the “major questions doctrine,” which suggests that Congress must clearly authorize the President to take actions with significant economic or political consequences. Whereas Chief Justice Roberts invoked this doctrine in part of his opinion, the three liberal justices declined to join that section, indicating a lack of full consensus on the reasoning behind the ruling.

What Happens Next: Refunds and Litigation

The ruling opens the door for importers who paid the Trump-era tariffs to seek refunds. Hundreds of cases were already pending at the Court of International Trade, but were stayed pending the Supreme Court’s decision. Those cases can now proceed. Justia

Former President Trump expressed frustration with the Court’s decision, questioning why it didn’t address the fate of the nearly $200 billion in revenue collected from the tariffs. Wikipedia The question of whether and how those funds will be refunded remains to be litigated, potentially for years to come, according to legal experts. Wikipedia
