Several Democratic-led states filed a lawsuit Thursday challenging President Trump's newly imposed tariffs, arguing they violate federal law similar to previous trade measures that were recently overturned by the Supreme Court.

The legal challenge follows a 6-3 Supreme Court decision that blocked Trump from using a 1977 emergency statute to implement broad tariffs on imported goods. The high court ruling found that the president lacked authority under that particular law to impose the sweeping trade levies.

After the Supreme Court's decision, the Trump administration has reportedly shifted to invoking alternative legal authority to continue implementing tariffs. The states bringing the new lawsuit contend that these replacement measures are similarly unauthorized under federal law.

The legal dispute represents the latest chapter in ongoing battles over presidential trade powers and the extent of executive authority to impose unilateral economic measures. The Supreme Court's recent ruling established new precedent limiting which emergency statutes can be used to justify tariff implementation.

Details about which specific states are participating in the lawsuit and the exact legal grounds being cited were not immediately available. The case is expected to focus on whether the alternative statutory authority being invoked by the administration provides sufficient legal basis for the tariffs.
