The U.S. Court of International Trade ruled Thursday that President Donald Trump's 10% [1] global tariffs were illegal and struck them down.
This ruling represents a significant legal setback for the administration's trade strategy. By invalidating the universal tariff, the court has limited the executive branch's ability to unilaterally raise costs on a broad spectrum of imported goods without specific legislative or legal justification.
The court's decision, delivered on May 7, 2026 [2], focused on the administration's reliance on Section 122 of the Trade Act of 1974. Judges said that the use of this specific provision to implement the 10% [1] global tariff constituted a misuse of trade law [3].
The ruling challenges the administration's interpretation of executive authority regarding international commerce. The court said that the broad application of the tariff did not align with the legal requirements set forth in the 1974 Act, a move that effectively halts the collection of these specific duties.
Legal representatives for the administration said they plan to appeal the ruling [4]. The government said that the tariffs were a necessary tool for economic leverage, though the court disagreed with the legal mechanism used to enact them [3].
Because the ruling targets the legality of the mechanism itself, the decision has immediate implications for businesses and consumers who were facing increased costs on imported products. The court's focus remained on the statutory limits of Section 122 rather than the economic merits of the tariffs themselves [3].
“The Court of International Trade ruled that Trump's newly imposed 10% global tariffs were illegal.”
This ruling establishes a judicial boundary on the use of the Trade Act of 1974, signaling that the executive branch cannot use specific statutory provisions as a blanket authority for universal tariffs. If the decision holds after appeals, the administration will be forced to seek different legal justifications or congressional approval to implement similar broad-based trade barriers.
