释新闻｜美最高法院6比3裁定特朗普全球关税违法，意味着什么？

Core Viewpoint - The U.S. Supreme Court ruled against President Trump's significant tariff policy, stating that the International Emergency Economic Powers Act (IEEPA) does not authorize the president to impose large-scale tariffs, leading to the invalidation of related tariffs previously enacted by the government [1][2]. Group 1: Supreme Court Ruling - The Supreme Court made a 6-3 decision, asserting that the IEEPA does not grant the president the power to impose tariffs without congressional authorization [1][3]. - Chief Justice John Roberts emphasized that the government failed to demonstrate any legal basis for the president's unilateral tariff authority under the IEEPA [3][4]. - The ruling may lead to prolonged legal battles regarding the potential refund of billions in tariffs collected from U.S. businesses [2][7]. Group 2: Trump's Response and Future Actions - In response to the ruling, Trump announced a new executive order imposing a 10% global tariff on all countries, effective February 24, which can last for up to 150 days unless Congress approves an extension [1][10]. - Trump indicated that tariffs imposed under national security grounds and other existing tariffs would remain in effect, suggesting a continued reliance on alternative legal frameworks for tariffs [2][9]. - Legal experts noted that the ruling could lead to significant financial implications for the U.S. Treasury, as the government may need to refund previously collected tariffs [7][12]. Group 3: Implications for Trade Policy - The ruling is expected to create uncertainty in global trade, prompting reactions from international partners, including the EU and Canada, who are reassessing their trade agreements with the U.S. [11][12]. - The decision may complicate Trump's ability to use tariffs as a tool in international negotiations, as it challenges the legal basis for his previous tariff policies [10][11]. - Analysts predict that the ongoing adjustments to U.S. trade policy will create new winners and losers in the market, affecting business recruitment and investment [12].
