US Federal Appeals Court Rules Most of Trump's Tariffs Unlawful

Strategic Insights -

A major decision in the United States, a federal appeals court has ruled that most of the tariffs imposed by President Donald Trump on foreign countries are indeed illegal. This significant ruling, made by a 7-4 margin, could lead to a significant challenge to the Trump administration's foreign economic policy. The decision concerns the comprehensive tariffs, which included a 10% base tariff on most countries worldwide, in addition to higher tariffs on China, Mexico, and Canada, enacted as part of Trump's "reciprocity" policy. Trump had justified these measures as necessary for national security and to balance the U.S. trade balance. The ruling centered on whether the president has the authority to impose such sweeping tariffs under the Emergency Economic Powers Act of 1977, which authorizes the president to take economic measures to address "extraordinary and unusual" threats to national security.
