The Supreme Court on Wednesday heard consolidated challenges to President Trump’s “Liberation Day” tariffs. Justices across the ideological spectrum pressed whether the emergency‑powers law at issue authorizes sweeping import duties, leaving the outcome uncertain.
On Nov. 5, 2025, the Supreme Court heard oral arguments in two consolidated cases — Learning Resources, Inc. v. Trump and Trump v. V.O.S. Selections — testing whether the International Emergency Economic Powers Act (IEEPA) authorizes the administration’s broad tariff program. The court fast‑tracked the disputes for its November sitting. (scotusblog.com)
During more than two hours of questioning, several conservative and liberal justices voiced skepticism about the government’s position. Chief Justice John Roberts and Justices Neil Gorsuch and Amy Coney Barrett, among others, pressed whether IEEPA — a 1977 statute most often used for targeted financial sanctions — can be read to permit revenue‑raising tariffs, a power traditionally exercised by Congress. Reporters at the argument described a notably cool reception for the administration’s view. (washingtonpost.com)
The challenged measures include the April 2025 “Liberation Day” announcement of a universal 10% levy on most imports, as well as earlier “trafficking” tariffs aimed at Canada, Mexico, and China and justified by fentanyl and border concerns. The administration relies on IEEPA’s reference to regulating “importation,” while challengers argue the law does not mention tariffs and was never designed to delegate open‑ended taxing authority.

Lower courts have largely sided with the challengers. In late spring and summer, the Court of International Trade and then the U.S. Court of Appeals for the Federal Circuit concluded that IEEPA does not authorize sweeping, across‑the‑board tariffs; the Supreme Court granted expedited review on Sept. 9 and set argument for Nov. 5.

What happens next carries significant economic and legal implications. Estimates suggest the government has collected roughly $88 billion under the challenged tariffs through early fall, and some reporting has raised the possibility that tens of billions could be subject to refund if the administration loses — though the scope of any remedy would depend on the ruling.

Outside the courtroom, the cases have drawn extensive commentary. According to Slate’s Amicus podcast, hosts Dahlia Lithwick and Mark Joseph Stern discussed the arguments with Marc Busch, the Karl F. Landegger Professor of International Business Diplomacy at Georgetown University; the episode notes that Busch joined a trade‑scholars amicus brief detailing IEEPA’s history and limits. Supreme Court dockets reflect the filing of a “Trade Scholars in Economics, Politics, and Law” brief in the consolidated cases. (podcasts.apple.com)
The suits were brought by importers and a coalition of states who argue that IEEPA’s text and structure, as well as the major‑questions and non‑delegation doctrines, foreclose using emergency powers to impose broad revenue‑raising tariffs without clear congressional authorization. A decision, which could come in weeks or months, will mark a major test of executive power in trade policy. (politico.com)
