The state of California opened a lawsuit in the District Court for the Northern District of California on April 16 against President Donald Trump's ability to use the International Emergency Economic Powers Act to impose tariffs. The two-count complaint claims that Trump acted beyond his statutory authority granted by IEEPA to impose the "reciprocal" tariffs and the tariffs on China, Canada and Mexico, and that Trump's tariff actions usurp legislative authority in violation of the U.S. Constitution (State of California v. Donald J. Trump, N.D. Cal. # 3:25-03372).
The Liberty Justice Center, a conservative litigation firm, issued a call for plaintiffs to challenge President Donald Trump's use of the International Emergency Economic Powers Act to impose tariffs on all goods entering the U.S. The group is looking to challenge this use of IEEPA "under the major questions and nondelegation doctrines."
The New Civil Liberties Alliance filed a lawsuit on behalf of paper importer Emily Ley Paper, doing business as Simplified, on April 3 challenging President Donald Trump's use of the International Emergency Economic Powers Act (IEEPA) to impose 20% tariffs on all goods from China. Filing suit in the U.S. District Court for the Northern District of Florida, Simplified laid out three constitutional and statutory claims against the use of IEEPA to impose tariffs and one claim that the tariffs violate the Administrative Procedure Act for unlawfully modifying the Harmonized Tariff Schedule (Emily Ley Paper, doing business as Simplified v. Donald J. Trump, N.D. Fla. # 3:25-00464).
