Model DiplomatMay 9, 20263 min readNorth America [Associated PressFederal court rules against new global tariffs Trump imposed after loss at the Supreme Court - The Washington Post](https://www.washingtonpost.com/business/2026/05/07/trump-global-tariffs-trade-court/d0bc0366-4a5d-11f1-a119-857cd2bf4fd4_story.html)[David J. LynchTrade court strikes down Trump’s latest tariffs - The Washington Post](https://www.washingtonpost.com/business/2026/05/07/tariffs-trade-court-ruling-trump/)[Thomson Reuters · Posted: May 07, 2026 5:26 PM EDT | Last Updated: May 8U.S. trade court rules in favour of plaintiffs who challenged Trump's global tariffs | CBC News](https://www.cbc.ca/news/world/trump-global-tariffs-trade-court-9.7191744) ## Trump’s tariff fallback gets boxed in again *The trade court’s ruling narrows the president’s tariff leverage, but the case is still only partly binding and the administration is already looking for another route.* Donald Trump’s tariff strategy took another legal hit on Thursday when the U.S. Court of International Trade ruled that his new 10% global duties were not justified under Section 122 of the 1974 Trade Act, according to [CNN](https://www.cnn.com/2026/05/07/business/tariff-case-ten-percent-trump-court-international-trade "cnn.com") and [CBC News](https://www.cbc.ca/news/world/trump-global-tariffs-trade-court-9.7191744 "cbc.ca"). The 2-1 decision came after the Supreme Court earlier this year knocked out Trump’s broader emergency tariffs, forcing the White House to shift to a different legal authority. That is the core dynamic: **Trump still wants tariff leverage, but the courts keep narrowing the tools he can use to apply it fast and broadly**. ## Courts are cutting into the tariff playbook The New York-based trade court found that the administration had not shown the kind of “large and serious” balance-of-payments problem required for Section 122, [CNN](https://www.cnn.com/2026/05/07/business/tariff-case-ten-percent-trump-court-international-trade "cnn.com") reported. The ruling was not a total shutdown. It applies directly only to the plaintiffs — two private importers and the state of Washington — and the court declined to issue a universal injunction, [CBC News](https://www.cbc.ca/news/world/trump-global-tariffs-trade-court-9.7191744 "cbc.ca") reported. That matters. Trump can still collect the 10% tariff from everyone else for now, and the levies are scheduled to expire in July unless the administration changes course or wins on appeal. That limited remedy is the White House’s opening. It can keep the policy alive while appealing to the Federal Circuit and, potentially, the Supreme Court, [CBC News](https://www.cbc.ca/news/world/trump-global-tariffs-trade-court-9.7191744 "cbc.ca") said. Trump’s own response was telling: he told reporters he would “do it a different way,” [CNN](https://www.cnn.com/2026/05/07/business/tariff-case-ten-percent-trump-court-international-trade "cnn.com") reported. In other words, the administration is treating the ruling less as a veto than as a search problem. ## Why this matters for trade power This is not just about one tariff schedule. It is about who controls the pace of U.S. trade policy. The president wants tariffs he can deploy unilaterally and quickly as bargaining chips against China, allies, and domestic opponents. The courts are signaling that those tools still exist, but only within narrower statutory lanes and with more room for challenge. That shifts leverage toward importers, litigants, and legal specialists — not Congress, but not the White House alone either. There is also a second-order effect for markets. Even when a ruling does not immediately erase a tariff for every importer, it adds uncertainty about refunds, compliance, and how long a levy will survive. [CNN](https://www.cnn.com/2026/05/07/business/tariff-case-ten-percent-trump-court-international-trade "cnn.com") noted that refund procedures from the earlier Supreme Court loss are still being phased in, while [CBC News](https://www.cbc.ca/news/world/trump-global-tariffs-trade-court-9.7191744 "cbc.ca") cited trade lawyers saying more companies may now sue for broader relief. For companies shipping into the U.S., that is a planning problem; for Trump, it is a political one. For broader political context, see [US Politics](https://modeldiplomat.com/discover/us-politics "modeldiplomat.com") and [Global Politics](https://modeldiplomat.com/discover/general "modeldiplomat.com"). ## What to watch next The next decision point is whether the Justice Department appeals immediately and whether other importers seek a wider injunction before the tariffs expire in July. If the administration pivots to another statute — especially Section 301 investigations already underway, as [CBC News](https://www.cbc.ca/news/world/trump-global-tariffs-trade-court-9.7191744 "cbc.ca") reported — the fight moves from whether Trump can use tariffs to how durable any replacement can be. That is the date that matters: July, when this tariff layer either dies, mutates, or gets folded into a new legal challenge.
