A coalition of 25 Democratic-led states has filed a new lawsuit seeking to stop President Donald Trump's latest round of tariffs, arguing the administration is attempting to revive a trade policy that the U.S. Supreme Court has already ruled unlawful. The case marks the latest chapter in an escalating legal battle over Trump's aggressive trade agenda, which has faced repeated challenges from businesses, states and federal courts. States argue tariffs violate constitutional limitsThe lawsuit was brought by attorneys general from 25 Democratic-led states, who contend that Congress, not the president, has the constitutional authority to impose taxes and tariffs. The states are asking the court to declare the tariffs unlawful, block their enforcement and order refunds for duties already collected. Legal fight follows Supreme Court defeatThe latest lawsuit comes months after the Supreme Court ruled that the International Emergency Economic Powers Act does not authorize presidents to impose broad global tariffs, dealing a major setback to Trump's earlier trade strategy.
