特朗普对等关税法院受挫，有待更换法律依据

Group 1: Legal and Trade Policy Implications - The U.S. International Trade Court overturned Trump's equal tariff measures, stating they exceeded the authority granted by the International Emergency Economic Powers Act (IEEPA) [1] - The ruling questions the legality of tariffs including a 10% base tariff and equal tariffs, potentially leading to their cancellation, but does not affect tariffs based on Section 232 and Section 301 [2] - The court mandated that the administration cease the collection of related tariffs within 10 days, but did not require the refund of already collected tariffs [2] Group 2: Future Tariff Strategies - The ruling increases uncertainty in tariff policies, but the Trump administration may still impose tariffs using alternative legal frameworks such as Section 122, which allows temporary tariffs up to 15% for a maximum of 150 days [3] - Section 232 allows tariffs if imports threaten national security, but requires a cumbersome investigation process by the Department of Commerce [3] - Section 301 has not seen new tariffs this year, likely due to existing tariffs still in effect and limited room for additional tariffs under the Biden administration [3] Group 3: Market and Negotiation Impact - The court's decision limits the Trump administration's ability to impose tariffs, weakening its position in trade negotiations [4] - A potential strategy for the Trump administration could involve short-term tariffs under Section 122 to gain time for further investigations and legislation regarding specific industry tariffs [4] - Risks include uncertainty in higher court rulings and the fluctuating nature of trade negotiations [4]
