The U.S. Court of International Trade struck down a 10% [1] global tariff imposed by President Donald Trump as illegal on Thursday, May 7, 2026 [3].
The ruling represents a significant legal setback for the administration's trade agenda, as it restricts the president's ability to unilaterally impose broad tariffs without specific congressional approval.
A panel of federal judges issued the decision in a 2-1 [2] split. The court found that the tariffs were not justified under the 1974 Trade Act and exceeded the legal authority granted to the executive branch. Because the administration failed to secure the necessary legislative backing, the court determined the measure was an overreach of presidential power.
This legal challenge follows a period of volatility in trade policy. The tariffs in question were prompted by a separate Supreme Court decision in February 2026 [4]. However, the trade court's ruling clarifies that the 1974 Trade Act does not provide a blanket authorization for the 10% [1] levy across all imports.
The decision comes at a critical juncture for international commerce, where businesses have been adjusting pricing, and supply chains to accommodate the global tariff. By ruling the measure illegal, the court has effectively halted the administration's current implementation of the fee.
“The federal trade court struck down the administration's 10% global tariff as illegal.”
This ruling establishes a legal boundary on the use of the 1974 Trade Act, signaling that the judiciary will scrutinize the executive branch's use of national security or economic emergency justifications to bypass Congress. It creates immediate uncertainty for the administration's trade strategy and may force a shift toward negotiating bilateral agreements or seeking formal legislative amendments to trade law.
