The US Supreme Court has agreed to review the legality of many of the tariffs imposed by US President Donald Trump on other countries in a fast-track process, with the parties set to begin presenting their arguments in November, the court said.
As stated in the announcement, “arguments are scheduled for the first week of November 2025“. The parties must submit their arguments to the court in writing by September 19. The tariffs in question will remain in effect during the trial.
The fast-track hearing means the Supreme Court could issue a decision before the end of the year. If the trial had been conducted under the usual procedure, this would not have happened before the summer of 2026.
On September 4, the Trump administration asked the Supreme Court to overturn an earlier decision that many of the tariffs imposed by Washington on other countries were illegal. The decision was issued on August 29 by the US Court of Appeals for the District of Columbia. The court found that Trump did not have the authority to impose many of the tariffs currently in force. The Washington administration believes that the appeals court's decision "creates uncertainty about ongoing negotiations with other countries" on trade issues and "imperils" existing agreements.
The appeals court's decision concerns tariffs imposed by the United States in April on many countries, as well as tariffs that Trump imposed in February on goods from China, Canada and Mexico. The case was filed after a group of business representatives filed a lawsuit against the US government. Entrepreneurs said the tariffs imposed by Washington were illegal and harmed their companies.
