The US Supreme Court struck down on Friday President Donald Trump’s sweeping tariffs that he pursued under a law meant for use in national emergencies, rejecting one of his most contentious assertions of his authority in a ruling with major implications for the global economy. The justices, in a 6-3 ruling authored by conservative Chief Justice John Roberts, upheld a lower court’s decision that the Republican president’s use of this 1977 law exceeded his authority. The court ruled that the Trump administration’s interpretation that the law at issue — the International Emergency Economic Powers Act, or IEEPA — grants Trump the power he claims to impose tariffs would intrude on the powers of Congress and violate a legal principle called the “major questions” doctrine.
