WASHINGTON — President Donald Trump celebrated a positive outcome from a federal appeals court regarding his extensive tariff policy, calling it a significant victory for the United States.

Trump shared on his social media platform that the court’s decision on Tuesday evening, allowing the government to continue imposing his broad import levies amid ongoing appeals of his major trade policy, signifies that the U.S. can employ tariffs as a protective measure against foreign nations.

“A great and important win for the U.S.,” Trump wrote.

The U.S. Court of Appeals for the Federal Circuit’s ruling maintains a previous decision after another federal court invalidated the tariffs on May 28, arguing Trump had exceeded his authority. The appeals court noted that the disputes over Trump’s tariffs present “issues of exceptional importance” and announced it would speed up the process, scheduling arguments for July 31.

The case involves 10% tariffs the Republican president imposed on almost every other country in April and bigger ones he imposed and then suspended on countries with which the United States runs trade deficits. It also involves tariffs he plastered on imports from China, Canada and Mexico to pressure them to do more to stop the illegal flow of immigrants and synthetic opioids across the U.S. border.

In declaring the tariffs, Trump had invoked emergency powers under a 1977 law. But a three-judge panel of the U.S. Court of International Trade ruled he had exceeded his power.

That ruling from the Court of International Trade came after several lawsuits arguing Trump’s tariffs exceeded his authority and left the country’s trade policy dependent on his whims.

The tariffs upended global trade, paralyzed businesses and spooked financial markets.
