Back in May, the U.S. Court of International Trade ruled that Trump overstepped his bounds by using IEEPA to apply tariffs. Just a day later, the decision was paused and tariffs were back on. The lawsuit was brought by a wine importer called V.O.S. Selections and four other small businesses. Analysts expect the case to reach the Supreme Court.

Trump has recently announced preliminary trade deals with Japan and other countries, and many of his paused "reciprocal" tariffs are set to resume next month.

Dozens of economies including India, Canada and Mexico face threats of higher tariffs Friday if they fail to strike deals with Washington.
