Supreme Court Limits Presidential Power: Trump’s Tariffs Unlawful

In a 6-3 decision Friday, the U.S. Supreme Court ruled that former President Donald Trump overstepped his authority by imposing sweeping tariffs on imports from nearly every U.S. trading partner. The ruling marks a major setback for Trump’s second-term trade agenda and has broad implications for the economy, consumers, and U.S. trade policy.

Chief Justice John G. Roberts Jr., writing for the majority, emphasized that Trump lacked the clear congressional authorization necessary to impose tariffs of “unlimited amount, duration, and scope.”

“The president asserts the extraordinary power to unilaterally impose tariffs… he must identify clear congressional authorization to exercise it,” Roberts wrote.

Justices Clarence Thomas, Samuel Alito Jr., and Brett Kavanaugh dissented.

Trump had relied on the 1977 International Emergency Economic Powers Act to levy tariffs on imports from over 100 countries, aiming to reduce the trade deficit, spur domestic manufacturing, and pressure trading partners.

The Supreme Court’s decision could force the government to reconsider these tariffs and may even require refunds to importers.
