此案事关全球经济，多名法官提出质疑，美最高法院激辩关税政策是否合法

Core Viewpoint - The U.S. Supreme Court is questioning the legality of the federal government's large-scale tariff implementation, which is based on a 1977 law intended for use during national emergencies, raising concerns about the balance of power between the presidency and Congress [1][2][4]. Group 1: Legal and Political Implications - The case is seen as one of the most significant in U.S. history, as it challenges the authority of the president to impose tariffs without congressional approval [2]. - The Supreme Court is reviewing an appeal from the federal government against lawsuits from five small businesses and twelve states that argue the tariff policy is illegal [2][4]. - Chief Justice Roberts and Justice Barrett expressed skepticism about the government's interpretation of the International Emergency Economic Powers Act, questioning whether it grants the president the authority to impose tariffs [4][5]. Group 2: Economic Impact - The tariffs, which have generated an estimated $89 billion in revenue from February 4 to September 23, 2023, are criticized for their negative economic consequences, including harming consumers and productive businesses [8][9]. - A recent poll indicates that 72% of Americans view the economy negatively, with many attributing rising living costs to the government's tariff policies [9]. Group 3: Future Considerations - If the Supreme Court rules against the government, it may lead to the cancellation of trade agreements and potential refunds to importers, which could have severe economic repercussions [6]. - The government has alternative options to impose tariffs, such as using Section 301 of the Trade Act of 1974, even if the current case does not go in its favor [8].
