Supreme Court Decision on Tariffs

On Friday, February 20,2026, the Supreme Court ruled that many of the Trump Administration’s tariffs were unconstitutional in a 6-3 court decision. The Court reviewed the use of the International Economic Emergency Powers Act (IEEPA), which allows the President to impose tarrifs in time of emergency. The Court found that the purpose for which the Trump Administration did not fall under the perview of IEEPA.

US Senator Ben Ray Luhán issued a press release on the topic stating: “This Supreme Court decision is an important step forward. Now, the Trump administration must provide certainty to American small businesses by refunding the costs they have endured and take real steps to repair our economic relationships around the world.”

Currently, it remains unclear how or if the US government is required to refund tariff revenue.

US Senator Martin Heinrich has also applauded the courts ruling and has been at work in the Senate to block tariffs from raising prices for New Mexicans. Heinrich cosponsored the No Tariffs on Groceries Act in January. This legislation is meant to prevent the enactment of tariffs that raise grocery costs for families. The No Tariffs on Groceries Act would require congressional approval for any tariff levied on food or agricultural products. While the law was blocked from passage, Heinrich is still committed to lowering grocery costs.
