US Supreme Court Limits Presidential Powers on Tariffs
Why in the News ?
The U.S. Supreme Court struck down tariffs imposed by President Donald Trump under the International Emergency Economic Powers Act (IEEPA), ruling that tariff powers lie with Congress. The judgment clarifies limits on presidential trade authority and strengthens legislative oversight, reinforcing principles of equal justice and access to justice in constitutional governance.

Supreme Court Ruling on Trump’s Tariffs:
- The U.S. Supreme Court, in a 6–3 decision, ruled that the International Emergency Economic Powers Act (IEEPA) does not grant the President authority to impose tariffs.
- The tariffs introduced by Donald Trump in 2025 were declared unconstitutional, as they lacked clear congressional approval.
- Trump had justified the tariffs after declaring national emergencies linked to drug trafficking and trade imbalances.
- These measures included 25% tariffs on imports from Canada and Mexico, 10% tariffs on Chinese goods, and additional reciprocal tariffs on several countries.
- The Court emphasised that tariffs fall under Congress’s constitutional authority to levy taxes and regulate foreign trade, upholding equal justice under the law.
Implications of the Verdict for Trade Policy
- The ruling restricts the use of emergency powers to impose tariffs, clarifying the legal boundary between executive and legislative authority and preventing discriminatory laws.
- However, the President may still impose tariffs under existing trade laws, provided statutory authority from Congress exists.
- Potential legal routes include Section 122 and Section 301 of the Trade Act of 1974, and Section 232 of the Trade Expansion Act of 1962.
- Businesses affected by the tariffs have filed lawsuits seeking refunds, although the ruling does not automatically provide a compensation mechanism, highlighting ongoing challenges in access to justice for affected parties.
- The tariffs had generated nearly $180 billion in revenue, increasing the economic stakes of the court decision.
