SCOTUS Curbs Presidential Tariff Power
A recent U.S. Supreme Court ruling has limited President Trump's authority to unilaterally impose tariffs. The decision could force the federal government to reimburse billions of dollars to importers affected by past duties, introducing significant uncertainty into ongoing trade negotiations.
The Supreme Court's 6-3 decision in *Learning Resources Inc. v. Trump* on February 20, 2026, hinged on the interpretation of the International Emergency Economic Powers Act of 1977 (IEEPA). The majority opinion, authored by Chief Justice John Roberts, asserted that the IEEPA's provision allowing the president to "regulate importation" does not extend to levying tariffs, as the power of taxation is explicitly granted to Congress by the Constitution. This ruling invalidated the legal foundation for a significant portion of the Trump administration's trade strategy, which had utilized the IEEPA to impose broad, country-specific tariffs by declaring a national emergency. The administration had argued that the act conferred nearly unlimited authority to impose duties in response to perceived emergencies, a claim no previous president had made. The financial fallout is substantial, with an estimated $166 billion in IEEPA tariffs collected from over 330,000 businesses now deemed unlawful. U.S. Customs and Border Protection is developing a new system to process these refunds, which will include interest, and expects it to be ready within 45 days, requiring "minimal submission from importers." In response to the ruling, all IEEPA-based tariffs were terminated by executive order on February 24, 2026. The administration immediately pivoted, invoking Section 122 of the Trade Act of 1974 to impose a new temporary 10% global tariff, arguing it is necessary to address the U.S. balance-of-payments deficit. This legal battle is not over, as a coalition of 24 states has already filed a lawsuit challenging the legality of the new tariffs under Section 122, a provision never before used to impose duties. The administration also continues to utilize other statutes for tariff authority, such as Section 232 of the Trade Expansion Act for national security-based tariffs on goods like steel and aluminum, and Section 301 of the Trade Act of 1974 for unfair trade practices.
