Overview
President Trump declared national emergencies over fentanyl trafficking and trade deficits, then used a 1977 law never intended for tariffs to slap duties on nearly every country. Federal courts at every level said he exceeded his authority. The tariffs stayed anyway, collecting $129 billion while 301,000 importers waited to see if they'd get refunds.
On February 7, 2025, the administration published the tariff orders—starting a two-year clock for refund claims. Now the Supreme Court must decide whether a president can impose what amounts to a massive tax increase by declaring an emergency, or whether Congress alone holds that power. The answer could validate or obliterate hundreds of billions in trade policy built on shaky legal ground.

Scenarios
Supreme Court Strikes Down IEEPA Tariffs, $129B Refund Scramble Begins
Discussed by: Constitutional Accountability Center, Brennan Center for Justice, trade law analysts across major firms including Holland & Knight and Mayer Brown
The Court rules IEEPA doesn't authorize tariffs, triggering the largest customs refund operation in U.S. history. Customs and Border Protection, already underfunded and understaffed, faces 301,000 importers demanding refunds totaling $129 billion. The process takes years, strains government finances, and vindicates congressional control over taxation. Trump could immediately reimpose similar tariffs using Section 232 national security authority or push Congress for legislation, but the precedent limiting emergency powers would stand.
Supreme Court Upholds Tariffs, Presidential Trade Power Expands Dramatically
Discussed by: Former Solicitor General Elizabeth Prelogar, government lawyers, analysts at PwC and Baker Tilly
The Court validates IEEPA as tariff authority, establishing that presidents can impose massive trade barriers by declaring emergencies without congressional approval. The $129 billion stays collected, importers lose refund hopes, and future presidents gain unprecedented economic leverage. Congressional trade authority effectively transfers to the executive branch. The ruling would encourage emergency declarations for policy goals—immigration, climate, industrial policy—backed by tariff threats.
Supreme Court Issues Narrow Ruling, Leaves Core Questions Unresolved
Discussed by: Legal scholars observing oral arguments, constitutional law experts
The Court invalidates these specific tariffs on procedural or narrow statutory grounds without deciding whether IEEPA could ever authorize duties. Perhaps it rules the fentanyl and trade deficit rationales don't constitute the type of emergency IEEPA contemplated, or questions whether the proclamations met statutory requirements. This preserves future executive flexibility while blocking Trump's particular approach, but creates ongoing uncertainty about the limits of emergency economic powers.
Supreme Court Splits the Difference, Validates Some Tariffs But Not Others
Discussed by: Trade policy analysts, importers, law firms advising on refund strategies
The Court distinguishes between the targeted fentanyl tariffs on China, Mexico, and Canada versus the sweeping Liberation Day reciprocal tariffs. It might uphold narrow emergency-linked duties while striking down broad economic tariffs, creating a messier refund situation where some importers get money back and others don't. This outcome would require extensive litigation to sort out which specific tariff lines survive and which fall, prolonging uncertainty for years.
Historical Context
Smoot-Hawley Tariff Act of 1930
1930-1934What Happened
During the Great Depression's onset, Congress passed the Smoot-Hawley Tariff Act raising duties on over 20,000 imported goods to protect American industries. Trading partners retaliated with their own tariffs. World trade collapsed by 66% between 1929 and 1934, deepening the Depression. U.S. exports fell from $7 billion to $2.5 billion.
Outcome
Short term: Immediate retaliation from Canada, Mexico, Europe devastated export-dependent industries and farmers.
Long term: Became the canonical example of protectionism's dangers, cited in every trade debate since. Led to decades of trade liberalization efforts.
Why It's Relevant
Trump's IEEPA tariffs triggered similar retaliatory threats from Canada, Mexico, and China. The scale—$129 billion collected—and breadth recall Smoot-Hawley's sweeping reach.
Youngstown Sheet & Tube Co. v. Sawyer (1952)
1952What Happened
During the Korean War, President Truman seized steel mills to prevent a strike he claimed would jeopardize national defense. The Supreme Court ruled 6-3 that he lacked authority—neither Congress nor the Constitution granted him power to seize private property, even in wartime emergency. Justice Jackson's concurrence established the foundational framework for analyzing presidential power: it's strongest when Congress approves, weakest when Congress prohibits.
Outcome
Short term: Truman returned the mills to private ownership, and the steel strike proceeded.
Long term: Created the Youngstown framework that courts still use to assess executive authority. Established that emergencies don't create power, they only occasion its exercise.
Why It's Relevant
The IEEPA case sits squarely in Youngstown's framework. Did Congress authorize tariffs when it passed IEEPA, or does the statute's silence mean prohibition? Courts apply Jackson's test.
Section 232 Steel and Aluminum Tariffs (2018)
2018-presentWhat Happened
In his first term, Trump used Section 232 of the Trade Expansion Act of 1962 to impose 25% steel and 10% aluminum tariffs, claiming imports threatened national security. Unlike IEEPA, Section 232 explicitly authorizes tariffs. Trading partners protested but the authority was clear, so legal challenges failed. The tariffs remained in place through Biden's presidency.
Outcome
Short term: Steel and aluminum industries got protection, but manufacturers using these metals faced higher costs. Allies imposed retaliatory tariffs.
Long term: Normalized using national security justifications for economic tariffs, setting precedent Trump expanded with IEEPA.
Why It's Relevant
Shows Trump had legal tariff tools available in Section 232. His choice to use IEEPA instead—a statute without explicit tariff authorization—is what created the constitutional crisis.
