• A federal court has ruled President Trump's sweeping tariffs exceed executive authority, potentially dismantling his trade agenda.
  • The decision removes key negotiating leverage and creates immediate uncertainty for thousands of daily imports.
  • White House officials decry the ruling as a 'judicial coup,' signaling a likely appeal.

Constitutional Rebuke of Presidential Trade Powers

The U.S. Court of International Trade delivered a unanimous blow to the administration's trade policy late Wednesday, declaring the 'Liberation Day' tariffs unconstitutional. The three-judge panel—comprising appointees from Reagan, Obama, and Trump administrations—found the White House violated separation of powers by implementing sweeping levies under 1970s emergency legislation.

'Any interpretation that delegates unlimited tariff authority is unconstitutional,' the ruling stated, invoking both the nondelegation and major questions doctrines. The decision immediately invalidates measures including a 10% global baseline tariff and targeted levies reaching 25% on key trading partners.

Market Disruption Looms

Customs officials now face operational chaos as the ruling throws into question tariff classifications for approximately 90,000 shipping containers entering U.S. ports daily. Importers who paid billions in disputed duties may file refund claims, while manufacturers relying on tariff protections saw related stocks dip in after-hours trading.

'This isn't just about legal theory—it's about real cargo sitting in real ports right now,' said one logistics executive who requested anonymity due to client sensitivities. 'The ruling gives us whiplash after two months of supply chain adjustments.'

Administration Digs In

White House deputy chief of staff Stephen Miller fired an opening salvo on social media, calling the decision part of a 'judicial coup.' Trade advisor Peter Navarro—who championed the tariff regime—reportedly told aides 'nothing has really changed,' though officials privately acknowledge the ruling undermines core economic policies.

Legal observers note the administration faces slim odds of staying the decision before the 2026 implementation window for reciprocal tariffs. 'They're playing constitutional chicken with an exceptionally well-reasoned opinion,' said Georgetown trade law professor Miriam Sapiro. 'Even conservative judges balked at this power grab.'
