Overview
- Chief Justice John Roberts, writing for the majority, said IEEPA does not authorize tariffs and that such sweeping economic actions require clear congressional approval.
- The ruling invalidates IEEPA-based duties including the near-global 'Liberation Day' levies and country-specific tariffs on Canada, Mexico, China and others, while leaving sectoral tariffs under other statutes intact.
- Justices Brett Kavanaugh, Samuel Alito and Clarence Thomas dissented, warning of serious practical consequences including a complicated process for returning billions already collected.
- U.S. Customs and Border Protection figures and independent estimates put IEEPA tariff collections in the roughly $130 billion to $175 billion range, and companies have begun positioning for refunds the Court left to lower courts and agencies to sort out.
- White House officials signaled they will seek narrower alternatives under laws such as Sections 232, 301 or 122, a path that faces procedural limits, likely litigation and renewed congressional scrutiny.
