May 29 (Reuters) - A federal appeals court temporarily reinstated the most sweeping of President Donald Trump's tariffs on Thursday, a day after a U.S. trade court ruled that Trump had exceeded his authority in imposing the duties and ordered an immediate block on them.
The United States Court of Appeals for the Federal Circuit in Washington said it was pausing the lower court's ruling to consider the government's appeal, and ordered the plaintiffs in the cases to respond by June 5 and the administration by June 9.
Wednesday's surprise ruling by the U.S. Court of International Trade had threatened to kill or at least delay the imposition of Trump's so-called Liberation Day tariffs on imports from most U.S. trading partners and additional tariffs on goods from Canada, Mexico and China. The latter was related to his accusation that the three countries were facilitating the flow of fentanyl into the U.S.
The trade court's three-judge panel ruled that the Constitution gave Congress, not the president, the power to levy taxes and tariffs, and that the president had exceeded his authority by invoking the International Emergency Economic Powers Act, a law intended to address threats during national emergencies.
