A United States trade court has delivered a significant blow to President Donald Trump’s aggressive trade policies, stopping most of his recently announced “Liberation Day” tariffs, including those targeting Chinese goods. The ruling, issued late Wednesday by the Court of International Trade, declared the import taxes “illegal.”The decision disrupts ongoing trade negotiations with numerous countries, adding new uncertainty for American businesses heavily reliant on international suppliers. The court found that Trump overstepped his authority in imposing the wide ranging tariffs he had dubbed "Liberation Day" tariffs, which were announced on April 2.These sweeping import taxes had previously sent shockwaves through financial markets, causing US stocks, bonds, and the dollar to fall. Global investors began to question their usual confidence in the US, and concerns arose about the US’s economic future as reliable trading partners such as Canada looked to diversify its economy away from America..In its ruling, the three-judge panel stated, “The challenged Tariff Orders will be vacated and their operation permanently enjoined.” This effectively stops Trump’s signature trade initiative, which included numerous new import taxes on almost every country.However, the legal battle may not be over. Just hours after the court’s decision, the Justice Department announced in a federal court filing its intention to appeal the ruling.The court’s decision came from two lawsuits filed last month. It applies to the 10% tariffs Trump put on all foreign products, as well as much higher tariffs on goods from several dozen specific nations. .To implement these, the president had invoked the International Emergency Economic Powers Act (IEEPA), a 1977 law granting emergency economic powers.The ruling also freezes separate tariffs on Mexican, Canadian, and Chinese goods. Trump had imposed these to pressure those governments to address human and drug trafficking. However, existing import taxes on specific items such as automobiles, auto parts, steel, and aluminum will remain in place.Several states, led by Democratic governors, argued in one lawsuit that they faced "direct financial harm" because the tariffs made imported goods used in public services more expensive. The other case was brought by five owner-operated businesses – V.O.S. Selections, Genova Pipe, MicroKits, FishUSA, and Terry Cycling. .They claimed harm from Trump’s improper use of executive power, citing sourcing difficulties and cash flow problems after the “Liberation Day” tariffs.The court highlighted that IEEPA permits the president to use emergency powers only "to deal with an unusual and extraordinary threat with respect to which a national emergency has been declared." Trump had cited the persistent US merchandise trade deficit since 1975 as the "emergency" justifying his broad tariffs.The court also rejected the tariffs imposed on Mexico, Canada, and China related to drug trafficking. It found these failed to meet the law's requirement of addressing an "unusual and extraordinary threat.".The judge panel said that instead of directly tackling cross-border trafficking, the tariffs were designed to "create leverage" to compel other governments to act.No previous president has utilized IEEPA to impose tariffs, and Trump's use sparked numerous lawsuits. While small businesses sued, larger corporations like Apple reportedly sought relief through private discussions with the White House. The government had argued that the IEEPA’s language allowing the president to “regulate … importation” granted him full tariff powers. The trade court disagreed, stating the law did not authorize “the President to impose whatever tariff rates he deems desirable.”
