美企发动集体诉讼，追讨特朗普关税千亿退款

Core Viewpoint - A new lawsuit has been filed questioning Trump's trade policies, particularly the high tariffs imposed under the International Emergency Economic Powers Act, with potential implications for businesses seeking refunds if the government loses [2][3]. Group 1: Lawsuit Details - The lawsuit aims to establish a category of businesses importing products from China or the EU, which could lead to significant refunds, as the government estimates nearly $500 billion in tariff revenue for the fiscal year [3]. - This lawsuit is at least the second filed in the past week, with the Supreme Court set to hear related cases, indicating a growing legal challenge against the tariffs [3]. - The lawsuit could involve amounts exceeding $100 million, highlighting the financial stakes for affected businesses [3]. Group 2: Government's Position - The White House maintains that Trump legally exercised emergency tariff powers granted by Congress, expressing confidence in a favorable Supreme Court ruling [4]. - If the Supreme Court rules the tariffs illegal, businesses that have paid these tariffs could seek refunds, potentially complicating the refund process for the government [4]. - The current cases focus on the legal authority under which tariffs were imposed, with less emphasis on what remedial actions would follow if the tariffs are overturned [4]. Group 3: Legal Strategy - The New Civil Liberties Alliance, representing various businesses, is pursuing a collective lawsuit to ensure broad relief for all affected entities, as previous cases did not seek to confirm a wider class of plaintiffs [5][6]. - The organization aims to prepare for a comprehensive challenge against the tariffs, indicating a strategic approach to counter the government's potential piecemeal defenses [6].
