突发，美国最高法院作出裁决：美高层对等关税和芬太尼关税违法！

Core Viewpoint - The U.S. Supreme Court ruled that the previous administration's imposition of certain aggressive tariffs was unlawful, limiting the executive's authority to unilaterally set tariffs under the International Emergency Economic Powers Act of 1977 [1][4]. Group 1: Legal Ruling - The ruling specifically targeted two types of tariffs: differentiated "reciprocal tariffs" imposed on different regions and punitive tariffs on certain goods from neighboring and related trade partners [4]. - Although tariffs on steel and aluminum products remain effective under other laws, the Supreme Court's decision has weakened the executive's administrative freedom in trade policy [4]. Group 2: Political Implications - The legal ruling has caused significant political upheaval, especially with midterm elections approaching, signaling a potential shift in trade protectionism [7]. - The ruling may undermine the confidence of core support groups for the administration, as it represents a check on the executive's policy execution capabilities [9]. - Observers, including those from Russia, are closely monitoring the situation to assess its impact on global supply chains and multilateral trade rules [9].
