12 US States Challenge All IEEPA Tariffs at Trade Court

Twelve U.S. states, led by Oregon, filed a lawsuit at the Court of International Trade challenging President Donald Trump's ability to impose tariffs using the International Emergency Economic Powers Act. The complaint contests all of Trump's tariff orders issued under IEEPA as a violation of both the statutory authority conveyed by IEEPA and the Constitution's principle of separation of powers. The suit, filed by Oregon Attorney General Dan Rayfield, also challenges CBP's series of Cargo Systems Messaging Service notices implementing the tariffs under the Administrative Procedure Act.
