On May 28, the U.S. Court of International Trade (CIT) ruled that the February tariffs on Canada, Mexico, and China, as well as the April reciprocal tariffs based on the International Emergency Economic Powers Act (IEEPA), were invalid.
This summary judgment was reached unanimously by a three-judge panel without formal trial proceedings, ruling in favor of the plaintiffs (a group of states and small businesses).
The Trump administration immediately appealed to the Court of Appeals for the Federal Circuit (CAFC), which granted a stay of execution on May 29.
Currently, the Trump administration’s tariffs are based on three main legal authorities.
