Trump's tariff policy faces judicial challenges as companies sue the president for overstepping his authority on taxation.

The U.S. Court of International Trade is before a lawsuit against the Trump administration's tariff policies. The Center for Liberal Justice, a nonpartisan legal group, filed a lawsuit on behalf of five tariff-hit importers, accusing the president of imposing tariffs without congressional authorization and asking the court to halt the trade measures.

The companies involved cover multiple industries such as wine importers and educational equipment manufacturers, directly targeting the "Liberation Day" tariff order issued by Trump on April 2 and his tariff policy against China. Attorney Schwab pointed out that the Constitution clearly stipulates that the legislative power of tariffs belongs to Congress, and the President does not have the authority to unilaterally make such significant economic decisions.

The White House responded that the tariff policy is aimed at addressing a "national emergency" and protecting the rights of American businesses and workers. Spokesman Fields emphasized that the president's actions are meant to create a fair international trade environment and correct the long-standing trade imbalance.

This case has sparked a constitutional authority dispute, placing the legitimacy of tariff policies under judicial review, which could have far-reaching implications for the trade legacy of the Trump administration.
