A U.S. federal trade court ruled on May 8, 2026 [2], that the Trump administration's 10 percent [1] global tariffs are unlawful.
The decision represents a significant legal check on executive trade authority. By striking down these tariffs, the court limits the administration's ability to unilaterally impose broad import taxes without specific legislative authorization.
The U.S. Court of International Trade in New York determined that the administration's justification for the tariffs was insufficient [1]. The court said the 10 percent [1] tariffs fell outside the authority granted by the 1974 Trade Act [1].
Legal challenges to the tariffs focused on whether the executive branch exceeded its statutory power. The court found that the administration did not meet the legal requirements necessary to invoke the 1974 Trade Act for such a broad application of tariffs [1], [3].
There are conflicting reports regarding the immediate scope of the ruling. Some reports indicate the court struck down the global tariffs entirely [4], while other accounts suggest the court issued a narrow block that leaves some aspects of the policy in place [2].
Because the ruling identifies the tariffs as illegal, the administration must now either appeal the decision or find a new legal mechanism to sustain its trade policy. The court's focus on the 1974 Trade Act emphasizes the necessity of adhering to congressional mandates when altering international trade agreements.
“The court declared the administration’s 10% global tariffs unlawful.”
This ruling underscores the tension between executive orders and statutory law in U.S. trade policy. By invalidating the use of the 1974 Trade Act for these specific tariffs, the judiciary is asserting that national security or economic justifications must meet a strict legal threshold to override existing trade laws. This may force the administration to seek explicit congressional approval for future broad-based tariffs.
