Twenty-five states led by Oregon filed a federal lawsuit challenging President Trump's Section 301 tariffs, escalating a broad legal offensive against the administration's trade policies. The coalition of states argues that Trump lacks authority under Section 301 of the Trade Act of 1974 to unilaterally impose the tariffs without congressional approval.
Oregon Attorney General Ellen Rosenblum spearheaded the effort, building on the state's history of challenging tariff actions. The lawsuit targets tariffs on goods imported from China, Mexico, Canada, and other trading partners. States in the coalition represent manufacturers, agricultural exporters, and consumer-facing businesses that face higher costs from the duties.
The legal challenge rests on separation-of-powers arguments. The plaintiffs contend that while Section 301 grants the president trade authority, it does not permit the sweeping, unilateral tariff increases Trump implemented. They argue Congress retains the power of the purse and must approve major trade actions that affect interstate commerce and federal revenue.
This marks a significant state-level challenge to Trump's trade agenda. Previous litigation over tariffs has produced mixed results, with courts sometimes upholding executive trade authority while other cases have progressed on narrow grounds. The states seek declaratory relief and an injunction blocking enforcement of the tariffs.
Trade economists warn the tariffs increase costs for manufacturers and consumers across sectors. States like Oregon, with significant agricultural and technology exports, face particular exposure to retaliatory trade measures. The lawsuit reflects growing state government resistance to the tariffs, regardless of political affiliation.
The case arrives as congressional Republicans remain divided on Trump's tariff strategy. Some party members have expressed concern about economic impacts, while others back the administration's approach as necessary leverage in trade negotiations. The Supreme Court will ultimately determine how much deference courts owe presidential tariff decisions.
