A federal appeals court panel has expressed skepticism regarding President Donald Trump's authority to impose broad tariffs under emergency powers granted by the International Emergency Economic Powers Act (IEEPA) of 1977. The judges questioned the administration's legal justification for using a law historically applied to sanction enemies or freeze assets to enact sweeping, worldwide tariffs. The court session involved scrutiny of Trump's claim that the emergency powers allowed him to override the tariff schedule enacted by Congress. Oral arguments revealed doubts about the Department of Justice's defense of this tariff authority. The case represents a significant legal challenge to the Trump administration's tariff policy, with potential implications for the latest round of tariffs imposed on dozens of countries. If the appeals court rules against Trump, the decision is expected to be appealed to the Supreme Court. The litigation comes as a trade deadline approaches and has drawn attention to the economic impact of these tariffs, including reactions in sectors such as trucking. The outcome could affect taxpayers and international trade relations.
