The International Emergency Economic Powers Act doesn't confer the power to impose tariffs, California argued at the U.S. District Court for the Northern District of California. Responding to the government's motion to transfer the state's challenge -- which centers on President Donald Trump's use of IEEPA to impose tariffs -- to the Court of International Trade, California argued that CIT doesn't have exclusive jurisdiction to hear the case, since "IEEPA does not provide for tariffs" (State of California v. Donald J. Trump, N.D. Cal. # 3:25-03372).
The U.S. District Court for the Northern District of Florida set a May 12 deadline for parties to file amicus briefs in a case brought by importer Emily Ley Paper, doing business as Simplified, against President Donald Trump's tariffs on China imposed under the International Emergency Economic Powers Act. After the company opened its lawsuit, the U.S. moved to transfer the case to the Court of International Trade (see 2504150022). So far in the case, only one amicus brief has been filed, and it came from the Trump-aligned America First Legal Foundation, which sought to defend the government's bid to transfer the case (see 2504160047) (Emily Ley Paper, d/b/a Simplified v. Donald J. Trump, N.D. Fla. # 3:25-00464).
The U.S. District Court for the District Columbia set a hearing for May 27 to hear two children's educational materials producers' motion for a preliminary injunction against all tariff action taken by President Donald Trump under the International Emergency Economic Powers Act. In a text-only order, Judge Rudolph Contreras set the hearing to take place at 3 p.m. EDT both on the preliminary injunction bid and the U.S. government's motion to transfer the case to the Court of International Trade (Learning Resources v. Donald J. Trump, D.D.C. # 25-01248).
The U.S. offered its most fulsome defense of President Donald Trump's reciprocal tariffs to date, submitting a reply to a group of five importers' motion for a preliminary injunction and summary judgment at the Court of International Trade on April 29. The government argued that the text, context, history and purpose of the International Emergency Economic Powers Act lets the president impose tariffs and that IEEPA doesn't confer an unconstitutional delegation of authority to the president (V.O.S. Selections v. Donald J. Trump, CIT # 25-00066).
Two Illinois producers of children’s educational materials challenged April 22 President Donald Trump’s use of the International Emergency Economic Powers Act to impose tariffs, adding their complaint to a growing pile making similar claims (see 2504250038, 2504140061 and 2504230067). They, like other challengers, are seeking a preliminary injunction, saying that their businesses are already suffering irreparable harm as a result of the tariffs (Learning Resources, Inc. v. Donald J. Trump, D. D.C. # 25-01248).

Former U.S. Trade Representative Robert Lighthizer, who served in that role in President Donald Trump's first term, told an audience at the Council on Foreign Relations that he thinks "there’s a reasonable chance the [Court of International Trade (CIT)] would enjoin" tariffs levied under the International Emergency Economic Powers Act, or IEEPA. Trump used IEEPA to levy 25% tariffs on Canada and Mexico over fentanyl and migration, as well as 20% tariffs on China over fentanyl, and used it to levy 10% tariffs on countries other than those three, and an additional 125% tariffs on Chinese goods.
The U.S. District Court for the District of Montana on April 28 denied a motion from four members of the Blackfeet Nation that sought to keep the established schedule on its motion for a preliminary injunction against President Donald Trump's tariffs on Canada after the Montana court transferred the matter to the Court of International Trade (Susan Webber v. United States, D. Mont. # 4:25-00026).
The Pacific Legal Foundation, the libertarian legal advocacy group that recently brought a case against the legality of tariffs imposed under the International Emergency Economic Powers Act on behalf of 11 importers, has had "preliminary" talks with the other advocacy groups that have brought cases challenging the tariffs on whether to proceed with separate cases. Molly Nixon, attorney at the foundation, told us she's "in touch" with the two other groups who have brought cases against the tariffs, the New Civil Liberties Alliance and the Liberty Justice Center, but that nothing is confirmed about whether the groups will combine cases.
The following lawsuit was filed recently at the Court of International Trade:
