NextFin News - A coalition of 24 U.S. states, led by New York and California, filed a formal motion with the U.S. Court of International Trade on Friday, April 10, 2026, demanding the immediate nullification of U.S. President Trump’s latest round of global tariffs. The legal challenge targets a 15% across-the-board import duty implemented via executive action last month, a move the states argue bypasses constitutional limits on executive power and ignores a recent Supreme Court mandate that curtailed the administration’s previous trade policies.
The litigation centers on the administration’s use of Section 122 of the Trade Act of 1974, a provision intended for use during "large and serious" balance-of-payments deficits. According to the filing, the states contend that U.S. President Trump has "manufactured" a crisis to justify protectionist measures that the Supreme Court had already signaled were overreaching. The coalition, which includes Arizona, Oregon, and Illinois, claims the tariffs will cost their respective economies billions in increased consumer prices and supply chain disruptions, specifically citing the impact on the automotive and technology sectors.
White House spokesperson Kush Desai stated on Friday that the administration would "vigorously defend" the President’s actions, maintaining that the tariffs are a necessary tool for national economic security. However, the legal pressure is mounting following a decision by Judge Richard Eaton of the Court of International Trade earlier this week. Eaton ruled that all importers of record are entitled to the benefits of the Supreme Court’s prior invalidation of similar duties, a precedent that the 24 states argue should apply directly to this new 15% levy.
The economic impact of the 15% tariff is already being felt across state lines. In California, state officials estimate that the duties could reduce annual GDP growth by 0.4% if they remain in place through the fiscal year. New York Attorney General Letitia James, a frequent litigant against the administration, argued in the filing that the executive branch cannot use "emergency" trade statutes as a permanent workaround for congressional authority over taxation and commerce. The states are seeking not only a permanent injunction against the tariffs but also a court order requiring the federal government to refund any duties already collected under the new policy.
Market analysts remain divided on the likely outcome of this specific challenge. Stephen Myrow, managing partner at Beacon Policy Advisors and a veteran observer of Washington trade policy, noted that while the Supreme Court’s recent skepticism toward executive overreach provides a strong tailwind for the states, Section 122 grants the President broad "emergency" discretion that has rarely been tested in this context. Myrow, who has historically maintained a cautious view of the administration’s legal standing in trade disputes, suggested that this case could serve as the definitive test for the limits of the Trade Act of 1974.
The legal battle comes at a sensitive time for the U.S. economy, which is grappling with the inflationary pressures of a restructured global trade map. While the administration argues that the tariffs will eventually force manufacturing back to U.S. soil, the immediate reality for the 24 states involved is a spike in the cost of intermediate goods. Retailers have already begun signaling price hikes for the summer season, citing the 15% duty as a primary driver. The Court of International Trade is expected to hear oral arguments on the motion for a preliminary injunction within the next thirty days.
