John Roberts on Tariffs
TL;DR
Chief Justice John Roberts authored the opinion limiting the President's unilateral authority to impose sweeping tariffs under emergency law.
Key Points
He wrote that the words in IEEPA cannot support the President's asserted power to impose tariffs or duties.
The Chief Justice held that the expansive tariffs failed the major questions doctrine test because Congress did not clearly delegate the power of the purse.
His opinion on February 20, 2026, involved a 6-3 decision rejecting the executive's reliance on IEEPA for tariff imposition.
Summary
John Roberts, as Chief Justice, authored the majority opinion that struck down sweeping tariffs imposed by the President, finding they exceeded the authority granted by the International Emergency Economic Powers Act (IEEPA). He asserted that the words "regulate" and "importation" within IEEPA could not support the power to impose duties or taxes, a power explicitly granted to Congress first in the Constitution. He notably relied on the major questions doctrine, arguing that such a consequential delegation of the "core congressional power of the purse" would require clear statutory language from Congress, which IEEPA lacked.
His opinion emphasized judicial restraint by stating the Court claims no special competence in economics but must fulfill its role under Article III by examining the text and context of the statute. Roberts noted that the interpretation sought by the executive branch would grant the President power to unilaterally impose unbounded tariffs, free from the procedural limits found in other explicit tariff statutes. This stance demonstrates a consistent adherence to limiting executive overreach, particularly when Congress holds a primary enumerated power, irrespective of the administration involved.
