特朗普关税遭遇司法滑铁卢：美法院裁定特朗普不拥有无限征税权

Core Viewpoint - The U.S. International Trade Court (CIT) ruled that the International Emergency Economic Powers Act (IEEPA) does not grant the President unlimited authority to impose tariffs, leading to the annulment of related tariff measures [1][7]. Group 1: Court Ruling Details - The CIT combined two cases, one initiated by the Liberty Justice Center on behalf of five small businesses challenging the "reciprocal tariffs" and another by the Oregon Attorney General representing twelve states against global tariffs, retaliatory tariffs, and fentanyl tariffs [3]. - The court confirmed that the IEEPA does not explicitly authorize the President to impose unlimited tariffs, which have significant economic and political implications [4][5]. - The ruling stated that the tariffs imposed by the Trump administration exceeded the authority granted by the IEEPA and violated constitutional principles [6][7]. Group 2: Implications for Trade Policy - The ruling could represent a significant policy shift, particularly benefiting small and medium-sized enterprises that struggle to absorb the costs of tariffs [6]. - The decision emphasizes that trade decisions should not be made unilaterally by the President without Congressional authorization, reaffirming the importance of legislative oversight [4][5]. - The CIT's ruling applies nationwide, affecting all importers, but does not address tariffs authorized under other laws, such as those related to steel and aluminum [7].
