U.S. Court Rules Trump’s 10% Global Tariffs Illegal in Major Trade Policy Decision
Ruling exposes a deeper clash over executive authority, separation of powers and who gets to set trade policy.
The brief
A three-judge panel of the U.S. Court of International Trade ruled 2-1 that President Trump’s 10% global tariff imposed under Section 122 of the Trade Act of 1974 was unlawful because the statute did not authorize sweeping, across-the-board import duties. The decision follows a Supreme Court ruling that similarly invalidated earlier tariffs under IEEPA. Supporters of the court judgment emphasize separation-of-powers limits and the danger of unchecked executive emergency powers; critics emphasize the executive’s need to respond quickly to perceived trade imbalances and economic threats. The disagreement is less about the factual effects of a 10% surcharge than about the proper institutional guardrails for making trade policy in crises.
On May 7–8, 2026 a three-judge panel of the U.S. Court of International Trade (CIT) issued a 2–1 decision holding that the Trump administration’s 10% global tariff imposed under Section 122 of the Trade Act of 1974 was unauthorized by law. The tariffs were adopted as a replacement for broader tariffs struck down by the Supreme Court earlier in 2026 for exceeding the International Emergency Economic Powers Act (IEEPA). Plaintiffs — the state of Washington and two small businesses (Burlap & Barrel and Basic Fun!) — argued that the Section 122 action similarly violated constitutional separation of powers principles and statutory limits on executive authority.
The CIT’s opinion focused on statutory interpretation and institutional allocation of taxing and tariff powers. The court concluded that Congress did not provide the president with a blank check to declare a “balance-of-payments deficit” or an amorphous emergency and thereby impose sweeping, economy-wide import surcharges. The judges warned that permitting such expansive executive discretion would effectively allow presidents to impose import duties — a power the Constitution assigns to Congress — whenever the executive chose to label a situation an emergency.
Procedurally, the ruling invalidated the tariffs as unauthorized but provided relief directly to the plaintiffs; collection for most importers remained in place while the government pursues appeals. The administration signaled plans to seek review in the U.S. Court of Appeals for the Federal Circuit and, if necessary, the Supreme Court, meaning the tariffs will likely remain administratively in force during multi-stage appeals. That gap between the legal holding and practical relief has important economic consequences: businesses continue to face elevated input costs and pricing uncertainty until a final judicial resolution or legislative action removes or affirms the tariffs.
The legal dispute tracks a deeper upstream conflict about institutional roles and trust. One side frames the issue as a classic separation-of-powers defense: tariffs are taxes/duties whose permanent or far-reaching imposition requires clear congressional authorization. Under this view, doctrines like the Major Questions Doctrine exist to prevent executive usurpation of consequential economic policymaking. The opposing view treats executive flexibility as a necessary tool for responding rapidly to global economic shifts and perceived unfair trade practices, arguing that statutory tools like Section 122 were written to provide temporary emergency authority and should be available when needed.
Economic and business reactions emphasize pragmatic harms: small importers and retailers said the Section 122 surcharge raised costs, squeezed margins, and injected uncertainty into supply chains; some welcomed the CIT ruling as partial relief. Economists noted that striking down the universal surcharge could reduce the risk of broad price spikes, though sector-specific tariffs or future policy moves could still increase costs. Legal scholars flagged the decision’s signal to future administrations and to Congress: if courts tighten the margin for unilateral emergency tariffs, Congress may be forced either to legislate clearer emergency trade authorities or accept greater vulnerability of domestic industries to sudden import competition.
Politically, the case is likely to remain contentious. Supporters of stronger executive trade tools will argue that judicial constraints hamper the nation’s ability to counter perceived imbalances quickly; opponents will counter that allowing presidents to raise import duties without clear statutory authorization subverts representative accountability and invites politicized economic coercion. Ultimately, the dispute is caught between two institutional logics: the need for nimble policy tools in crises and the constitutional demand that major economic choices be rooted in clear congressional enactments. The appeals process and possible Supreme Court review will test where modern American trade power sits on that spectrum and whether Congress will act to clarify its own role.

Selections, Inc.) on February 20, 2026 held that IEEPA did not authorize broad, across-the-board import tariffs because IEEPA allows regulation of importation but not the levying of duties reserved for Congress.
