Twenty-five US states file a lawsuit challenging President Donald Trump’s latest global tariffs, which take effect last month. The states ask the U.S. Court of International Trade to block the tariffs and declare them unlawful, arguing the administration unlawfully replaces duties that courts previously struck down. The lawsuit is filed by the states after other legal challenges have emerged, including complaints from small businesses alleging the tariff actions are illegal.
According to reporting, the states contend the administration violates Section 301 of the Trade Act—the legal basis the administration uses for the tariffs. They argue the justification for the new tariff measures does not meet statutory requirements, including claims that the administration failed to follow required procedures tied to that authority.
The new lawsuit adds to an existing pattern of litigation around the tariff program, with multiple stakeholders seeking judicial review. The case places the tariffs’ legality before the Court of International Trade, where the states seek relief that would prevent the tariffs from remaining in force while the dispute is adjudicated.
