In a momentous ruling on Thursday, the U.S. Court of International Trade declared President Donald Trump’s recent imposition of a universal 10% tariff on global imports to be invalid. This decision, ascended by a 2-1 majority, arrives as a significant legal defeat for the Trump administration, which has frequently relied on tariffs as a tool of its international economic strategy.
The ruling was a result of litigation filed by several states and a collection of small businesses that had argued against the legality of Trump’s tariff measures. This cadre of challengers had brought their grievances before the court in March, questioning the administration’s utilization of tax impositions on global imports under the newly enacted tariff regime.
Previously, in a dramatic turn of events earlier in February, the Supreme Court had overturned Mr. Trump’s initial comprehensive set of tariffs, often referred to as the “Liberation Day” tariffs which were implemented under the auspices of the International Emergency Economic Powers Act (IEEPA) in April 2025. This Act traditionally grants the President the authority to regulate international commerce in response to unusual and extraordinary threats. However, in a notable 6-3 ruling, the Supreme Court judged that the IEEPA did not furnish President Trump the authority he claimed to impose such broad tariffs.
In response to the Supreme Court’s ruling, the Trump administration swiftly introduced a new set of global tariffs under Section 122 of the Trade Act of 1974. This legal provision primarily allows the President to impose tariffs temporarily, for up to 150 days, to address major and severe balance-of-payments deficits. It seemed the administration’s strategy was to deploy these temporary tariffs as a stop-gap measure while exploring more permanent solutions through investigations into the trade practices of various countries.
The legal contention brought before the U.S. Court of International Trade centered on these Section 122 tariffs. In their detailed 53-page decision, the court labeled these tariffs as “unlawful”. The judgement pointed not only to procedural failings in their imposition but also highlighted the tangible “economic harm” inflicted upon the suing plaintiffs. The court order dictated an immediate cessation of tariff impositions for the state of Washington and the two businesses that were the primary plaintiffs. Furthermore, it mandated the issuance of refunds plus interest pertaining to all tariffs these plaintiffs had previously paid.
Significantly, the court refrained from issuing a universal injunction that would have nullified the tariffs altogether, thereby limiting the scope of the ruling to the involved plaintiffs and hinting at potential further legal challenges.
The pronouncement from the court explicitly stated that the Trump administration had failed to justify the continuation of unlawful tariff imposition under Section 122. The Trump administration’s interpretation of “balance-of-payments deficits” was specifically criticized. Judicial notes highlighted the administration’s focus being improperly placed on narrower economic metrics such as trade and current account deficits – these being more specific gauges of goods, services, and certain financial transfers – as opposed to the broader and mandated focus on general payments deficits.
Reacting to the verdict late Thursday, President Trump expressed his nonchalance, remarking that nothing coming out of the court proceedings surprises him anymore. He specifically criticized the judges ruling against the tariffs as being part of the “radical left”. Despite this legal setback, the President hinted at continued tariff strategies, suggesting that his administration would explore alternate methods to achieve their economic objectives.
On the bench, the decision saw a division along appointive lines, with two judges appointed during President Barack Obama’s tenure siding with the majority, while a judge appointed by President George W. Bush dissenting.
The ruling also comes at a time when the Trump administration had begun issuing refunds to businesses which had paid tariffs under the now-overturned IEEPA tariffs. The timeline and specifics of these returns, although not directly addressed in Thursday’s ruling, remain a significant focus as the administration navigates its next steps amidst ongoing legal challenges to its trade policies.
Furthermore, the long-term implications of these legal confrontations over tariff policies will likely resonate across the U.S.’s international trade relations and domestic economic strategies. As the situation develops, business leaders, international trade experts, and legal scholars will closely watch the fallout from this latest judicial ruling for hints of the United States’ future trade policy and legal landscapes under the ever-contentious administration of Donald Trump.
