The vast majority of U.S. President Donald Trump¡¯s global tariffs were deemed illegal and blocked by the nation¡¯s trade court on Wednesday, dealing a major blow to a pillar of his economic agenda.

A panel of three judges at the U.S. Court of International Trade in Manhattan issued a unanimous ruling which sided with Democratic-led states and small businesses who had accused Trump of wrongfully invoking an emergency law to justify the bulk of his levies. The court gave the administration 10 days to ¡°effectuate¡± its order, but it didn¡¯t provide any specific directions of steps it must take to unwind the tariffs.

The order applies to Trump¡¯s global flat tariff, elevated rates on China and others, and his fentanyl-related tariffs on China, Canada and Mexico. Other tariffs imposed under different powers, like so-called Section 232 and Section 301 levies, are unaffected, and include the tariffs on steel, aluminum and automobiles.
