I saw this message when I woke up in the morning. Brother Wu's explanation is already very comprehensive. I would like to add the latest content: 1. The United States Court of International Trade has ruled that the global tariffs announced by the Trump government on the "Liberation Day" violated the law and exceeded the President's authority under the International Emergency Economic Powers Act of 1977 (IEEPA). The ruling permanently prohibits the enforcement of these tariffs and requires the US Customs and Border Protection to cease the collection of related tariffs within 10 days. 2. The court pointed out that the Trump government regarded the long-standing trade deficit and the inflow of illegal drugs as a "state of national emergency" and implemented tariffs on this basis, but these reasons failed to meet the "abnormal and unusual threat" standard required by IEEPA. Therefore, the court believes that the President has no authority to unilaterally impose such extensive tariffs in this situation. 3. The Trump government has appealed against the ruling and may seek a temporary injunction during the appeal period to resume the collection of tariffs. However, due to the unanimous opinion of the three judges that the President's actions exceeded legal authority. 4. The court's ruling mainly targets the "Liberation Day" global tariffs implemented by the Trump administration under the 1977 International Emergency Economic Powers Act (IEEPA), holding that the president has no authority to unilaterally impose such broad tariffs in this situation. However, the court did not deny the tariff measures implemented by the President under other legal authorizations, such as Section 232 of the Trade Expansion Act of 1962. Therefore, the Trump government can continue to implement some tariff policies in accordance with other laws. Although the court ruling restricts the President's tariff authority under IEEPA, the White House may seek other legal grounds or administrative measures to continue advancing its trade policy. The Trump government may temporarily levy import taxes on countries with large trade deficits with the United States in accordance with Article 122 of the Trade Law of 1974. 6. According to the ruling of the United States Court of International Trade, if the Trump government fails to appeal and the ruling finally takes effect, enterprises that have paid the illegal "Liberation Day" tariff will be entitled to a refund, including interest. According to data from the US Customs and Border Protection (CBP), since the implementation of these tariffs in January 2025, the average daily revenue has been about $250 million, and the cumulative total has exceeded $21 billion. 7. The main plaintiff promoting the lawsuit against the Trump government's "Liberation Day" tariff is the Liberty Justice Center, a non-profit legal organization in the United States, which filed a lawsuit on behalf of five small import enterprises. These enterprises include V.O.S. Selections, Inc., a wine and spirits importer headquartered in New York. In addition, 12 states led by Oregon have also raised similar legal challenges to the Trump government. In general, this is a great challenge to Trump's political career. After all, the main thing Trump does after taking office is tariffs. If tariffs are determined to be "illegal", it will be a great blow to Trump and the Republican Party, especially many of Trump's decrees will be controversial.
