May 30, 2025 — The U.S. Court of International Trade has ruled that U.S. President Donald Trump’s attempts to unilaterally raise tariffs are “invalid and cannot be implemented,” throwing the president’s ongoing trade negotiations into uncertainty.
However, the U.S. Department of Justice quickly appealed the ruling, and on 29 May, the U.S. Court of Appeals for the Federal Circuit temporarily stayed the trade court’s ruling while it considers motions from both sides.
