A coalition of a dozen states on Wednesday sued the Trump administration in the U.S. Court of International Trade in order to stop its tariffs, which the states claim have brought chaos to the U.S. economy.

The lawsuit argues that President Donald Trump cannot impose tariffs through the International Emergency Economic Powers Act, alleging that doing so was illegal, and that only Congress can impose tariffs.

“By claiming the authority to impose immense and ever-changing tariffs on whatever goods entering the United States he chooses, for whatever reason he finds convenient to declare an emergency, the President has upended the constitutional order and brought chaos to the American economy,” the lawsuit said, according to the Associated Press.

The states asked the court, which is based in New York, to declare the actions unlawful and bar the administration from imposing the tariffs on U.S. trading partners.

The lawsuit was filed by attorneys general from Arizona, Colorado, Connecticut, Delaware, Illinois, Maine, Minnesota, Nevada, New Mexico, New York, Oregon and Vermont.
