On April 23rd local time, a coalition of 12 states in the United States filed a lawsuit with the New York International Trade Court, accusing the Trump administration’s “reciprocal tariffs” policy of violating the Constitution and requesting the court to rule that the policy is illegal and prevent its implementation. The states involved in the lawsuit include New York, California (previously sued separately), Arizona, and others, covering major economic centers on both the east and west coasts, representing nearly 40% of the US population and 50% of the import trade volume.
