• The U.S. Court of International Trade ruled against President Trump's sweeping tariffs, finding he exceeded authority under IEEPA.
  • White House officials downplay the setback, expressing confidence in appeal options and alternative tariff mechanisms.
  • Market analysts suggest limited immediate impact on trade negotiations given administration's remaining tools.

Court Delivers Blow to Trump's Trade Policy

In a significant legal setback for the Trump administration, the U.S. Court of International Trade blocked what appears to be the administration's most comprehensive tariff measures on May 28, 2025. The court found President Trump exceeded his authority by invoking the International Emergency Economic Powers Act (IEEPA) to justify the tariffs.

"If anybody thinks this caught the administration by surprise, think again," said Peter Navarro, President Trump's trade adviser, in remarks to Bloomberg Television following the ruling. The administration had apparently anticipated potential legal challenges, with Navarro adding "Nothing's really changed" regarding their trade policy objectives.

Alternative Paths Forward

While preparing an appeal, White House officials signaled they have other mechanisms available. Navarro mentioned Section 122 tariffs as a potential alternative, though he noted these would be limited to 15% for 150 days. National Economic Council Director Kevin Hassett stated the administration remains confident in their legal position, telling reporters they believe the court ruling is incorrect and expect to prevail on appeal.

Market reaction appeared muted, with analysts at major financial institutions suggesting the ruling wouldn't dramatically alter ongoing trade negotiations. The administration's apparent determination to pursue alternative measures may have reassured markets that the broader trade agenda remains intact.

Legal Distinctions Drawn

The court's decision highlighted key differences between Trump's tariffs and previous presidential actions. Unlike Nixon's more limited tariffs that stayed within congressionally-established rates, Trump's measures were deemed excessively broad in their claimed authority. This distinction could prove crucial as the administration prepares its appeal.

U.S. Trade Representative Jamieson Greer is expected to address available policy tools in coming days as the administration works to maintain momentum on its trade priorities despite this judicial obstacle.
