美最高法院“对等关税”裁决在即，特朗普最新表态：不会亲自前往

Core Viewpoint - The article discusses the upcoming Supreme Court hearing regarding the Trump administration's "reciprocal tariffs" policy, highlighting its potential implications for presidential powers and U.S. trade policy [3][4]. Group 1: Tariff Policy and Legal Framework - The Trump administration has imposed extensive import tariffs under the International Emergency Economic Powers Act (IEEPA), with U.S. businesses paying nearly $90 billion in tariffs as of September 23, accounting for over half of the total tariff revenue for fiscal year 2025 [3][7]. - The IEEPA allows the president to impose measures if there is an "unusual and extraordinary threat" to national security, which Trump argues is due to significant trade deficits [7][9]. - Legal challenges have emerged from businesses and state governments, claiming that the IEEPA does not explicitly grant the authority to impose tariffs, and previous court rulings have deemed such tariffs illegal [8][9]. Group 2: Implications of Supreme Court Decision - Analysts suggest that the Supreme Court may issue a limited ruling, maintaining presidential powers while imposing restrictions on the declaration of national emergencies [10]. - If the IEEPA tariffs are ruled invalid, the government may need to refund billions in tariffs collected, which could negatively impact the U.S. economy [11]. - The potential ruling could also affect other tariff measures under different legal frameworks, which require more complex procedures and may limit the president's ability to impose tariffs quickly [12].
