A U.S. appeals court has declared that the majority of tariffs imposed by President Donald Trump are unlawful, raising the prospect of a legal battle that could disrupt his foreign policy agenda.The decision covers Trump’s so-called “reciprocal” tariffs — applied to most countries worldwide — along with additional duties targeting China, Mexico, and Canada.However, the ruling will not be enforced until October 14, giving the administration time to petition the Supreme Court for review.Reacting on Truth Social, Trump denounced the ruling, warning that if it stands, it would “literally destroy the United States of America.”
