决定特朗普关税命运时刻来了，美最高院公开庭辩，法官对关税合法性深表怀疑

Core Viewpoint - The U.S. Supreme Court is debating the legality of President Trump's tariffs, which could have significant economic implications for the country if ruled against the administration [1][2]. Group 1: Legal Context - The core dispute revolves around whether Trump can invoke the International Emergency Economic Powers Act (IEEPA) to impose tariffs on trade partners, a power not explicitly granted for tariff imposition [1][2]. - If the court rules against the Trump administration, it may have to rely on more limited tariff laws and could face refund claims amounting to hundreds of billions of dollars [2]. Group 2: Supreme Court Proceedings - Chief Justice John Roberts questioned the government's reliance on a precedent that does not pertain to tariffs, emphasizing Congress's core power over taxation [3]. - Justices Barrett and Gorsuch expressed skepticism about the government's arguments, particularly regarding the broad application of tariffs to numerous countries [4][5]. Group 3: Government's Defense - The government's chief lawyer argued that the tariffs are regulatory rather than revenue-generating, asserting that they are necessary to address significant economic issues [6]. - The government faced challenges from liberal justices who pointed out the historical context of the IEEPA and questioned the interpretation of its powers [6]. Group 4: Opposition's Argument - The opposing lawyers argued that tariffs are indeed taxes and that the IEEPA should not undermine the established global tariff framework [7]. - They highlighted the disproportionate tariffs imposed on certain countries, such as a 39% tariff on Switzerland despite a trade surplus, and projected that these tariffs could generate an additional $3 trillion for the U.S. by 2035 [7]. Group 5: Case Background - The case was brought by a group of small businesses and 12 states, challenging Trump's authority to impose tariffs under the IEEPA [8].
