US Supreme Court to Decide Fate of Trump’s Tariffs on Wednesday
The US Supreme Court will hear a landmark case on November 5 that could determine whether presidents can impose tariffs using emergency powers without congressional approval. The outcome may force the Trump administration to withdraw its “Liberation Day” tariffs and reshape global trade relationships.
Key Implications
- A ruling against Trump could invalidate all “Liberation Day” tariffs and subsequent rate hikes
- The administration would need to roll back tariffs or face legal injunctions
- Global trade deals with EU, Japan, South Korea, and UK could unravel
- Ongoing trade talks with India would be disrupted
According to the Global Trade Research Initiative, “Such a ruling would mean all ‘Liberation Day’ tariffs—and subsequent rate hikes—lack a lawful basis. The administration would have to roll them back or face injunctions halting their collection.”
Legal Battle Over Presidential Power
The case, Learning Resources Vs Trump, centers on whether the International Emergency Economic Powers Act (IEEPA) allows presidents to impose tariffs. The petitioners argue that tariff-setting power belongs to Congress, not the executive branch.
Two key legal questions are being considered:
- Jurisdiction: Whether the case belongs in federal district court or the Court of International Trade
- Authority: Whether IEEPA actually permits presidents to impose tariffs at all
The petitioners invoke the “major questions doctrine,” arguing that allowing presidents to declare economic emergencies and set tariffs unilaterally would upset the constitutional balance of powers.
Lower Courts Have Ruled Against Trump
Three courts have already rejected the administration’s position:
- April 26, 2025: US District Court rejected IEEPA tariff powers argument
- June 14, 2025: Court of International Trade ruled IEEPA doesn’t authorize general tariffs
- August 2, 2025: Federal Circuit upheld ruling, finding Congress never delegated such authority
If the Supreme Court strikes down Trump’s use of emergency powers, he could attempt to reimpose tariffs under Section 301 or 232, but this would require new investigations and face additional legal challenges.
The case is being closely watched worldwide as a critical test of executive power and constitutional separation of powers.
