Overview

  • A three-judge panel of the US Court of International Trade ruled on May 28 that President Trump's 'Liberation Day' import duties exceed the authority granted by IEEPA and permanently enjoined their enforcement.
  • The decision does not affect existing tariffs on steel, aluminum and automobiles imposed under separate statutory provisions.
  • The Trump administration filed an immediate appeal to the US Court of Appeals for the Federal Circuit and pledged to defend its use of emergency powers for trade policy.
  • Financial markets rallied on the news, with US stock index futures and key international equities gaining ground after the verdict.
  • The court gave the government ten days to issue administrative orders reflecting the permanent injunction and noted at least five related legal challenges remain pending.
