Supreme Court Overturns Trump’s General Tariffs

The Supreme Court struck down President Donald Trump’s sweeping tariffs in a 6-3 decision on Friday, February 20, 2026, ruling that the president exceeded his authority under the International Emergency Economic Powers Act (IEEPA) by imposing duties on imports from nearly every U.S. Trading partner without congressional approval.

The court found that the tariffs, which Trump had imposed through a series of executive orders citing national emergency powers, were not authorized by Congress under IEEPA, which allows the president to regulate commerce only in response to an unusual and extraordinary threat originating outside the United States to national security, foreign policy, or the economy.

Justice Brett Kavanaugh, in his dissenting opinion, warned that the decision could create uncertainty for trade agreements and suggested that the federal government may be required to refund billions of dollars to importers who paid the tariffs, even if some had already passed those costs on to consumers.

The ruling noted that importers had paid more than $200 billion in tariffs during 2025, though the court did not address whether or how the federal government should provide refunds for those payments.

President Trump responded to the ruling by saying he would sign an executive order imposing a 10% global tariff under Section 122 of federal law and explore other tariff avenues through alternative legal mechanisms.

The decision marks a significant setback to Trump’s economic agenda, which had centered on using tariffs as a tool to pressure trading partners and renegotiate trade deals, and throws U.S. Trade policy into uncertainty as businesses and importers await clarification on next steps.

The Supreme Court’s ruling clarifies the limits of presidential power in trade policy, affirming that Congress holds the authority to set tariff rates and that the president cannot unilaterally impose sweeping duties under emergency powers without legislative backing.
