Roberts court shuts door on tariffs but leaves room for Trump to prevail.
Evidence and Verdict
For
Chief Justice Roberts wrote that the authority in the International Emergency Economic Powers Act (IEEPA) does not embrace the power to impose tariffs, and the Supreme Court issued a 6–3 ruling striking down the IEEPA-based global tariffs. Multiple accounts note the ruling was limited to the IEEPA question and did not address tariffs imposed under other statutory authorities. The Court and reporting point out other statutes, such as Section 232 of the Trade Expansion Act, expressly reference duties and were not before the Court, leaving those legal routes unresolved.
Against
The opinion emphasized the lack of historical precedent and the breadth of the authority the President claimed, signaling judicial skepticism that could constrain executive tariff power more broadly. Much of the revenue from Trump-imposed tariffs derived from the IEEPA measures that were invalidated, meaning the ruling is a significant practical defeat even if other legal paths remain available.
Verdict
The claim is TRUE because the Roberts Court expressly held that IEEPA does not authorize tariffs (shutting that door) while limiting its decision to that statute and leaving other statutory authorities (e.g., Section 232 and other laws) unadjudicated, which preserves some legal avenues for the administration to pursue tariffs.
