Internet reported that a U.S. federal court (the U.S. Court of International Trade) blocked U.S. President Trump's "Liberation Day" tariffs from taking effect on Wednesday, ruling that Trump invoked the International Emergency Economic Powers Act to impose comprehensive tariffs on the grounds of trade deficit and other grounds., is an act of exceeding authority. The Manhattan-based International Trade Court stated that the U.S. Constitution gives Congress exclusive rights to regulate trade with other countries, and that the president's international emergency powers to protect the U.S. economy cannot be overridden. The lawsuit, filed by the nonpartisan Liberty Justice Center on behalf of five small U.S. businesses that import goods from countries targeted by tariffs, is the first major legal challenge to Trump's tariffs. These companies all said the tariffs would harm their business capabilities. The lawsuit is one of seven court challenges against Trump's tariff policies, in addition to challenges from 13 U.S. states and other small business groups. (Jin Shi)
