President Trump may have gotten his way with tariffs on some countries, but his overhaul of American trade policy has not gone unchallenged.

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.

President Donald Trump asked the US Supreme Court to turn away a challenge to his sweeping tariffs, telling the justices they should let the legal fight develop before getting involved.
