JUST IN: Supreme Court rules 6 to 3 against Trump on tariffs. "IEEPA does not authorize the President to impose tariffs" "Had Congress intended to convey the distinct and extraordinary power to impose tariffs, it would have done so expressly, as it consistently has in other tariff statutes" ***Important: The Supreme Court did NOT weigh in on whether the gov't has to issue refunds for tariffs already collected. Only Kavanaugh talks about this in his dissent.
