A legal challenge is underway over the president’s claim of sweeping powers to impose tariffs across the entire economy without direct congressional authorization. Critics argue the move exceeds statutory limits, raising concerns about executive overreach and the separation of powers. The dispute centers on whether the president’s actions align with existing trade laws or represent an unchecked expansion of authority. Legal experts and policymakers are closely watching the case, which could set a precedent for future trade policy decisions.


Their brief says the president is asserting "essentially boundless" authority to impose "economy-wide tariffs untethered from the statute Congress enacted."
