There were many reasons raised as to why Trump’s unliteral imposition of tariffs violated the law and the Constitution. A three-judge panel of the Court of International Trade, including judges appointed by Reagan and Trump, held that every single argument raised precluded Trump from imposing tariffs, as I argued here last April.
The US Court of International Trade just issued a unanimous ruling in the case against Trump’s “liberation day” tariffs filed by Liberty Justice Center and myself on behalf of five US businesses harmed by the tariffs. The ruling also covers the case filed by twelve states led by Oregon; they, too, have prevailed on all counts. All of Trump’s tariffs adopted under the International Emergency Economic Powers Act of 1977 (IEEPA) are invalidated as beyond the scope of executive power, and their implementation blocked by a permanent injunction. In addition to striking down the “Liberation Day” tariffs challenged in our case (what the opinion refers to as the “Worldwide and Retaliatory Tariffs”), the court also ruled against the fentanyl-related tariffs imposed on Canada, Mexico, and China (which were challenged in the Oregon case; the court calls them the “Trafficking Tariffs”).
