突发！美国最高法院裁定特朗普政府大规模关税政策违法！美国或需退还1750亿美元关税

Core Viewpoint - The U.S. Supreme Court ruled that the Trump administration's imposition of tariffs under the International Emergency Economic Powers Act lacked clear legal authority, maintaining a lower court's decision with a 6-3 vote [1][3]. Group 1: Legal Context - The Supreme Court's decision limits the President's ability to impose tariffs under the International Emergency Economic Powers Act but does not completely strip the President of tariff authority [1][3]. - The ruling was based on lawsuits filed by businesses and 12 states, which argued that the unilateral imposition of tariffs was unprecedented [1]. Group 2: Financial Implications - Economists from the University of Pennsylvania estimated that tariffs imposed under the International Emergency Economic Powers Act exceeded $175 billion, which may need to be refunded following the Supreme Court's ruling [3]. - The Trump administration had previously imposed tariffs on products such as copper, steel, and aluminum under other trade laws, indicating ongoing tariff authority despite the ruling [1][3]. Group 3: Political Reactions - Trump expressed concerns about the potential financial implications of a negative ruling, stating it could lead to significant costs for the country [3]. - In response to questions about the impact of a ruling against the administration, Trump indicated that alternative methods, such as a licensing system, could be employed if current tariff tools were restricted [4].
