The United States Supreme Court on Friday ruled that President Donald Trump violated federal law with his sweeping unilateral tariffs across the globe, in a huge setback to the White House on an issue that has Trump’s foreign policy and economic agenda. The ruling is widely seen as the big blow to Donald Trump’s second administration at the conservative-leaning Supreme Court. Just last year, the bench had consistently backed the president through a string of emergency decisions related to immigration, the removal of independent agency heads and sweeping reductions in federal spending.In a 6-3 verdict, the court held that the tariffs went beyond the scope of the law, with Chief Justice John Roberts authoring the majority opinion.“The president asserts the extraordinary power to unilaterally impose tariffs of unlimited amount, duration, and scope,” Roberts wrote for the court, reported CNN. “In light of the breadth, history, and constitutional context of that asserted authority, he must identify clear congressional authorization to exercise it.”
