After Supreme Court ruling: US court: Trump’s new tariffs are probably legal

Since February 24, 2026, the United States has imposed a 10 percent tariff on most foreign imports. Trump imposed the levy after the Supreme Court declared many of his previous tariffs illegal. For the new tariffs, he used a trade law from 1974 that limits collection to a maximum of 150 days.

Case could go to the Supreme Court

The Court of International Trade in New York concluded at the beginning of May that Trump had exceeded his authority with the new instrument and suspended the tariffs. A few days later, the appeal court initially suspended the first instance’s ruling – a decision which it has now confirmed. The plaintiffs against the government include Washington state and two companies.

The appeals court said both sides had presented convincing arguments. However, the US government would face irreparable damage if the tariffs were unlawfully left in force until a ruling was made. In addition, Trump’s government has sufficiently demonstrated “that it will probably be successful in this matter.” It is possible that the case will go to the Supreme Court in Washington following a ruling by the appeals court.
