In a 6-3 ruling, the Supreme Court overturned most of President Trump's expansive tariffs on U.S. trading partners, dealing a major blow to his aggressive trade policies. The decision found that the president exceeded his authority under the law known as IEEPA, which the administration had used to justify over $133 billion in tariffs in 2025 alone. While the White House says it will impose new duties under a different law, the ruling significantly curtails Trump's ability to unilaterally raise trade barriers.

Why it matters

Trump's tariff-based trade war reshaped global supply chains and relationships with longtime U.S. allies. The Supreme Court's ruling now throws that approach into uncertainty, raising questions about potential refunds to importers and the future direction of American trade policy under a divided government.

The details

In the majority opinion, Chief Justice John Roberts wrote that the words 'regulate importation' in the IEEPA law 'cannot bear the weight' of giving the president unilateral power to impose tariffs. The ruling could force the government to refund billions in tariff payments, though Treasury Secretary Scott Bessent suggested the administration may resist those payouts. Trump immediately announced new 10% global tariffs under a different law, but those will expire in 150 days unless Congress approves an extension.

  • The Supreme Court issued its 6-3 ruling on February 21, 2026.
  • Trump announced new 10% global tariffs under Section 122 of the Trade Act of 1974 shortly after the decision.
  • The Section 122 tariffs will expire in 150 days on July 20, 2026, unless Congress extends them.
