Tariff legality in court
Judges at the U.S. Court of International Trade pressed sceptical questions about the legal basis for the administration’s 10% global tariff, signalling real doubt about whether a trade deficit alone justifies wide duties.

Three judges in New York spent Friday asking a basic question the White House struggled to answer: what exact law lets a president put a 10% tax on imports from almost every country on earth. The case is now at the U.S. Court of International Trade, the federal court that handles customs and trade fights. (reuters.com) (cit.uscourts.gov) The tariff took effect on February 24, 2026, and it hit goods entering the United States with a flat 10% charge at the border. A coalition of 24 mostly Democratic-led states and two small businesses sued to stop it. (reuters.com) (pbs.org) This is Trump’s backup tariff plan, not his first one. In February 2026, the Supreme Court struck down a broader set of earlier tariffs, so the administration switched to a narrower tool from the Trade Act of 1974. (apnews.com) (nytimes.com) That 1974 tool is Section 122, and it lets a president impose tariffs of up to 15% for up to 150 days if the United States faces a “large and serious” balance-of-payments deficit. On Friday, judges pressed both sides on whether an ordinary trade deficit counts as the kind of emergency Congress meant. (axios.com) (reuters.com) A trade deficit is the simple part: the United States buys more goods from abroad than it sells. A balance-of-payments deficit is broader, because it covers the whole flow of money in and out of the country, including investment, and judges suggested the two are not the same thing. (axios.com) (politico.com) That distinction matters because the administration’s argument leans on the goods trade gap, while the challengers say the statute was written for a different kind of financial stress that the United States does not have now. Reuters reported that judges sounded doubtful that a trade deficit alone justifies broad tariffs. (reuters.com) (usnews.com) The court hearing also sits on top of a longer legal fight over how much tariff power Congress has handed to presidents. In May 2025, the same trade court ruled that earlier tariffs imposed under the International Emergency Economic Powers Act were unlawful, and in June 2025 the United States Court of Appeals for the Federal Circuit paused that ruling while the appeal moved forward. (cit.uscourts.gov) (cafc.uscourts.gov) So companies are planning around a tariff system that keeps changing in court. A manufacturer can sign a supply contract in March and still not know by summer whether a 10% import cost will survive, disappear, or be replaced by something else. (apnews.com) (reuters.com) The next move is a written ruling from the three-judge panel, and whatever they decide is likely headed for appeal. That means the real question for importers is no longer just what the tariff rate is on April 11, 2026, but which court will be setting it by the end of the year. (cit.uscourts.gov) (reuters.com)
