Summary

The U.S. Supreme Court, in a 6-3 decision, struck down President Donald Trump's broad global tariffs, including those related to persistent trade imbalances and fentanyl, ruling that he exceeded his authority under the International Emergency Economic Powers Act (IEPA). This decision undercuts a signature economic policy and represents a significant legal defeat. The court did not address the extent of importer refunds, leaving that complex issue to lower courts, with potential refunds totaling up to $170 billion. This ruling is considered historic, drawing comparisons to the 1930 Smoot-Hawley duties and the 1952 Youngstown Steel case, and significantly impacts presidential powers over the economy. While the market had largely anticipated this, with retail stocks like Lululemon seeing gains, the administration is expected to explore alternative tariff authorities like Sections 232, 301, or 122, though these offer less flexibility and lower rate ceilings than IEPA.

Key takeaway

For legal professionals advising clients on international trade, this Supreme Court ruling clarifies that the International Emergency Economic Powers Act (IEPA) cannot be used to impose broad tariffs. You should assess your clients' eligibility for tariff refunds, as the court left this to lower courts, potentially leading to class-action lawsuits. Be prepared for the administration to utilize other, more constrained tariff authorities, which may introduce new compliance complexities and uncertainties for importers.
