US Supreme Court Blocks Trump Tariff Policy, Citing Limits on Executive Power

Darwin, 21 February: The Supreme Court of the United States on Friday ruled that former President Donald Trump exceeded his authority in imposing sweeping counter-tariffs under emergency economic powers, delivering a significant setback to his administration’s trade agenda.

In a majority opinion, the court said the International Emergency Economic Powers Act (IEEPA) of 1977 does not authorize the president to unilaterally impose broad-based tariffs without explicit congressional approval. The decision reaffirmed that tariff-setting authority ultimately rests with Congress under the U.S. Constitution.

Trump had introduced a 10% “baseline tariff” on a wide range of imported goods after returning to office in January 2025, arguing that the measures were necessary to counter unfair trade practices and protect domestic industries. The policy targeted several countries, including China, India, Canada and Brazil, and included reciprocal duties in response to foreign trade restrictions.

Trump Criticizes Justices

Responding shortly after the ruling, Trump sharply criticized the justices who voted against the tariff policy. In a message posted on his social media platform, he said members of the court who opposed what he described as a “reasonable and correct tariff policy” should be ashamed.

He accused the justices of lacking patriotism and being disloyal to the Constitution, adding that he was embarrassed by their decision.

“The decision was ridiculous,” Trump wrote. “But now the adjustment process begins, and we will make every possible effort to collect even more revenue than before.”

Legal analysts say the ruling could significantly curb the scope of presidential authority in trade matters and may require the administration to seek congressional backing for future tariff measures.

The decision is expected to have broad implications for U.S. trade relations and executive power going forward.
