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.

President Trump's trade policy goes into effect Thursday, but could still be upended by a landmark court case.
