Chicago – August 30, 2025
A U.S. federal appeals court has ruled that most of President Donald Trump’s tariffs were illegal, delivering a major blow to one of his key trade policies. The case centered on tariffs Trump imposed on foreign steel, aluminum, and other goods, which he justified under national security grounds.
The court found that while presidents have authority under Section 232 of the Trade Expansion Act to impose such measures, Trump exceeded his legal powers by expanding tariffs beyond the scope originally approved. Judges noted that the administration failed to follow proper procedures, including consultation and time limits set by law.
The ruling could open the door for U.S. importers to seek billions in refunds for duties paid during Trump’s presidency. It also raises questions about how much flexibility presidents truly have in using trade laws for political or economic leverage.
