Trump Tariffs Blocked by U.S. Court of International Trade

A panel of federal judges on Wednesday blocked President Trump from imposing some of his steepest tariffs on China and other U.S. trading partners, finding that federal law did not grant him “unbounded authority” to tax imports from nearly every country around the world.

The ruling, by the U.S. Court of International Trade, delivered an early yet significant setback to Mr. Trump, undercutting his primary leverage as he looks to pressure other nations into striking trade deals more beneficial to the United States.

Before Mr. Trump took office, no president had sought to invoke the International Emergency Economic Powers Act, a 1977 law, to impose tariffs on other nations. The law, which primarily concerns trade embargoes and sanctions, does not even mention tariffs.

But Mr. Trump adopted a novel interpretation of its powers as he announced, and then suspended, high levies on scores of countries in April. He also used the law to impose tariffs on products from Canada and Mexico in return for what he said was their role in sending fentanyl to the United States.

On Wednesday, the Court of International Trade, the primary federal legal body overseeing such matters, found that Mr. Trump’s tariffs “exceed any authority granted” to the president by the emergency powers law. Ruling in separate cases brought by states and businesses, a bipartisan panel of three judges essentially declared many, but not all, of Mr. Trump’s tariffs to have been issued illegally.

It was not clear precisely when and how the tariff collections would grind to a halt. The ruling gave the executive branch up to 10 days to complete the bureaucratic process of ending them. The Trump administration immediately filed its plans to appeal in the U.S. Court of Appeals for the Federal Circuit.
