The Supreme Court delivered a stunning rebuke to Donald Trump's trade policy today, striking down his sweeping global tariffs in a 6-3 ruling that invalidates billions in levies and throws corporate supply chain strategies into chaos.
Chief Justice John Roberts, writing for the majority, held that the president "asserts the extraordinary power to unilaterally impose tariffs of unlimited amount, duration and scope" but "points to no statute" granting this authority under the International Emergency Economic Powers Act (IEEPA). The Court concluded bluntly: "IEEPA does not authorize the president to impose tariffs."
The ruling invalidates two categories of tariffs: country-by-country "reciprocal" tariffs ranging from 34% on Chinese goods to a 10% baseline elsewhere, and a separate 25% tariff on goods from Canada, China, and Mexico tied to fentanyl trafficking concerns. Steel and aluminum tariffs imposed under different statutory authority remain in place.
The decision creates immediate uncertainty for manufacturers who spent the past two years reshoring production or diversifying supply chains away from China. Companies that built new domestic facilities or shifted sourcing to countries like Vietnam and India now face questions about whether those investments made economic sense without the tariff shield.
Victor Schwartz of VOS Selections called the struck-down tariffs "arbitrary, unpredictable, and bad business" and "unconstitutional government overreach." The business coalition We Pay the Tariffs immediately demanded refunds on the approximately collected through mid-December under IEEPA authority.
