The U.S. Supreme Court will rule on whether Trump’s tariffs are legal

The United States Supreme Court has agreed to hear President Donald Trump‘s appeal after lower court rulings deemed some of his tariff policies illegal.

The case deals with the question of whether Trump exceeded his presidential authority with the imposition of his sweeping global tariffs earlier this year. He has argued the imposition was within his rights and that the U.S. trade deficit constitutes an emergency.

“The cases will be set for argument in the first week of the November 2025 argument session,” Supreme Court documents show.

Trump requested that the case, if the U.S. Supreme Court agreed to hear it, be fast-tracked.

Last week, Trump made the requests to the Supreme Court and told reporters that if the appeal is denied, the U.S. might have to “unwind” certain trade deals, including those with the European Union, Japan and South Korea, and would even have to refund some tariff revenues.

Regardless of the lower court ruling against Trump’s tariff policies, duties from imports are still allowed to be collected by the administration until the Supreme Court resolves the case.

U.S. Treasury Secretary Scott Bessent has said if the Supreme Court does not overturn the lower court ruling, then tens of billions of dollars in tariff revenues will likely need to be refunded.

According to U.S. government data, about $1.77 billion in tariff revenue has been collected specifically from Canadian imports, and does not include those from steel, aluminum and autos.
