Supreme Court Overturns Trump Tariffs: What Businesses Need to Know

Feb 25, 2026

On Friday, February 20, 2026, the Supreme Court ruled President Trump’s emergency tariffs unconstitutional, marking a pivotal moment in trade policy. In a 6-3 decision, the Court determined that President Trump’s use of the International Emergency Economic Powers Act (IEEPA) exceeded the scope of authority granted by Congress. Chief Justice John Roberts, writing for the majority, stated: “The president asserts the extraordinary power to unilaterally impose tariffs of unlimited amount, duration, and scope. In light of the breadth, history, and constitutional context of that asserted authority, he must identify clear congressional authorization to exercise it.”

While the decision invalidates the IEEPA tariffs, the Court did not address whether or how the government will return the estimated $129–$175 billion in IEEPA tariff revenue already collected from importers. Justice Kavanaugh, in his dissent, cautioned that “refunds of billions of dollars would have significant consequences for the U.S. Treasury.”

Notably, the ruling does not entirely preclude the use of tariffs as a strategic tool. Following the Court’s action, President Trump proposed a 10% global tariff under Section 121 of the Trade Act of 1974, subsequently increasing his proposal to 15% the next day.
