Supreme Court Takes Up Challenge to Trump’s Emergency Tariffs

The case will decide whether a 1977 emergency law lets a president impose tariffs without explicit congressional approval.

Overview

  • The justices will hear consolidated challenges on Wednesday, and the IEEPA-based tariffs remain in force under stays despite lower-court rulings against the administration.
  • The core dispute turns on whether IEEPA’s authority to “regulate importation” extends to broad, revenue-generating duties, with potential application of the court’s major-questions doctrine and foreign-affairs deference.
  • A divided Federal Circuit ruled 7–4 that the tariffs exceed statutory authority, while Judge Richard Taranto’s dissent backing the administration now anchors key arguments cited by the solicitor general.
  • Businesses and several states say the duties function as taxes borne by Americans and seek potential refunds, while the Justice Department defends them as regulatory measures targeting foreign threats.
  • Treasury Secretary Scott Bessent plans to attend arguments, and officials signal fallback options under other trade laws, including Sections 232, 301 and 338, if IEEPA is curtailed.
