A U.S. federal trade court ruled Thursday, May 7, 2026, that President Donald Trump's 10% across-the-board global tariffs are illegal [1], [2].

The ruling removes a significant pillar of the administration's trade policy and prevents the continued collection of duties from international partners. This decision disrupts the executive branch's strategy to use broad tariffs as a tool for economic leverage.

The U.S. Court of International Trade found that the 10% tariffs were invalid [1], [3]. The court said that the measures were unauthorized by law under Section 122 of the Trade Act [4], [5].

These tariffs were applied globally to a wide range of imports. According to court documents, the legal basis for the imposition of these duties did not meet the requirements set forth in the Trade Act [5].

The ruling comes as the tariffs were originally set to expire in July 2026 [6]. By striking them down now, the court has effectively ended the policy ahead of its scheduled sunset date.

The decision marks a significant legal check on presidential authority regarding international trade. The court's focus on Section 122 emphasizes that executive actions must align with specific legislative authorizations granted by Congress [5].

“A U.S. federal trade court ruled that President Donald Trump's 10% across-the-board global tariffs are illegal.”

This ruling establishes a legal precedent that limits the ability of the U.S. president to unilaterally impose broad, across-the-board tariffs without explicit and narrow legislative authority. By citing Section 122 of the Trade Act, the court has signaled that national security or economic justifications must be backed by statutory law, potentially shielding global trade partners from similar sweeping executive actions in the future.
