A panel of federal judges ruled Thursday that President Donald Trump's 10% global tariff is illegal [1].
The decision restricts the executive branch's ability to unilaterally impose broad import taxes without specific statutory justification. By finding the tariff inconsistent with existing law, the court creates a significant legal hurdle for the administration's current trade strategy.
The U.S. Court of International Trade in New York issued the ruling on May 7, 2026 [2]. The judges determined that the 10% [1] tariff was not justified under the 1974 Trade Act and therefore violated U.S. trade law [3].
According to court records, the three-judge panel reached the decision in a 2-1 vote [4]. The majority opinion focused on the limits of presidential authority regarding the 1970s-era Trade Act, concluding that the administration exceeded its legal mandate in implementing the global levy.
This ruling marks a major setback for the administration's economic agenda. The global tariff was designed to reduce trade deficits and encourage domestic production, but the court found the legal mechanism used to enact it was flawed [3].
The ruling comes as the administration continues to navigate complex trade relationships with global partners. Because the court found the tariff illegal under the specific provisions of the 1974 Trade Act, the government may be forced to rescind the levy or find a different legal justification to maintain it.
“The court ruled against President Donald Trump's 10% global tariff, finding it illegal.”
This ruling establishes that the 1974 Trade Act does not grant the president unlimited authority to impose blanket tariffs on all imports. It signals a judicial willingness to constrain executive trade powers, potentially forcing the administration to seek congressional approval or identify more specific legal triggers to justify future trade barriers.
