Court weighs 10% tariff
A federal trade court began considering the legality of the Trump administration’s 10% global import tax, a test of whether the White House used a new legal route to bypass earlier Supreme Court limits. States and small businesses have challenged the levy, warning that a ruling against the administration could sharply constrain the executive branch’s preferred trade‑policy playbook — and the dispute is already rippling into international disputes over car and other tariffs.

A court in New York spent Friday testing whether the White House can put a 10 percent tax on nearly everything Americans buy from abroad by calling trade deficits a national emergency. The hearing was in the United States Court of International Trade, the federal court that handles customs and tariff fights. (cit.uscourts.gov 1) (cit.uscourts.gov 2) The case matters because the tariff is unusually broad: a 10 percent baseline duty began hitting most United States imports on April 5, 2025, with Mexico and Canada carved out for separate treatment. The White House said the legal hook was emergency power, not the older trade laws presidents usually use for steel, cars, or country-specific disputes. (scmp.com) (supremecourt.gov) That legal hook is the International Emergency Economic Powers Act, a 1977 law better known for freezing assets and blocking transactions with foreign targets. In a February 20, 2026 decision, the Supreme Court said the fight over whether that law lets a president impose tariffs was squarely before the courts. (supremecourt.gov 1) (supremecourt.gov 2) The challengers are not just importers. One of the main Court of International Trade cases was filed by five small businesses and 12 states, and another case on the court’s public calendar for April 10, 2026 includes the State of Oregon and Burlap and Barrel, a spice company. (supremecourt.gov) (cit.uscourts.gov) Their basic argument is simple: the Constitution gives Congress the power to levy duties, and Congress already wrote more specific tariff laws for national security, unfair trade, and import surges. If a president can get the same result through a general emergency statute, those older guardrails start to look optional. (supremecourt.gov 1) (supremecourt.gov 2) The administration’s position is the opposite: the emergency law lets the president regulate importation when a foreign threat is “unusual and extraordinary,” and the White House says both drug trafficking and chronic trade deficits qualify. In the Supreme Court record, the government defended tariffs on Canada, Mexico, China, and a separate “reciprocal” tariff plan that set a floor of at least 10 percent on all trading partners. (supremecourt.gov) (supremecourt.gov) This is not the first time the trade court has pushed back. In a May 28, 2025 opinion, a three-judge panel at the same court granted summary judgment to plaintiffs challenging related tariffs, which helped set up the appeals that reached the Supreme Court. (cit.uscourts.gov) While judges sort out the statute, the policy is already spilling into diplomacy. On April 10, 2026, Trump said he would impose a 20 percent tariff on all cars imported from the European Union unless the bloc removed its own barriers, hours after the European Union imposed tariffs on about $3.3 billion of American products in response to United States metal duties. (scmp.com) So the courtroom question is narrower than the trade war it touches. The judges are not deciding whether tariffs are smart economics; they are deciding whether this president can reach for the emergency toolbox to do something Congress usually regulates with its own, more specific set of keys.
