States Sue Trump Administration Over 'Unlawful' Global Tariffs

The legal challenge initiated by 24 states on March 5, 2026, marks a critical escalation in the ongoing conflict over executive trade authority. By pivoting to Section 122 of the Trade Act of 1974, the Trump administration is testing a dormant legal lever after the Supreme Court blocked its previous use of emergency powers. This move represents a fundamental test of the limits of presidential power to unilaterally reshape the American economic landscape through trade barriers.

The core of the dispute lies in the administration's invocation of a statute intended to address 'large and serious' balance-of-payments deficits. Because Section 122 has never been utilized in its half-century history, the legal community and the markets are entering a period of profound uncertainty. The Congressional Research Service has noted that courts have had no prior occasion to interpret the language of this specific law, making the current litigation a landmark case for constitutional law and international trade.

government collected approximately $287 billion in customs duties, taxes, and fees—a staggering 192% increase from the previous year.

This legal pivot follows a significant judicial setback for the White House. In February 2026, the Supreme Court ruled 6-3 that the administration had overstepped its bounds by using the International Emergency Economic Powers Act (IEEPA) to levy previous duties. By shifting to Section 122, the administration is attempting to re-establish its tariff regime under a different authority, but the states argue this is a distinction without a difference. They contend that the new tariffs violate the constitutional principle of separation of powers, asserting that the power to tax and regulate commerce belongs primarily to Congress.

The economic stakes are immense and the data points to a massive shift in federal revenue. In 2025, the U.S. government collected approximately $287 billion in customs duties, taxes, and fees—a staggering 192% increase from the previous year. While the administration maintains that these costs are absorbed by foreign exporters and governments, the states’ lawsuit aligns with numerous economic studies suggesting the burden falls squarely on American businesses and consumers. For industries reliant on global supply chains, the prospect of a 15% blanket tariff creates a 'chaos' factor that complicates long-term capital expenditure and pricing strategies.
