The 6-3 decision centers on tariffs imposed under an emergency powers law, including the sweeping “reciprocal” tariffs he levied on nearly every other country.
It's the first major piece of Trump's broad agenda to come squarely before the nation's highest court, which he helped shape with the appointments of three conservative jurists in his first term.
The majority found that the Constitution “very clearly” gives Congress the power to impose taxes, which include tariffs. “The Framers did not vest any part of the taxing power in the Executive Branch,” Chief Justice John Roberts wrote.
Justices Samuel Alito, Clarence Thomas and Brett Kavanaugh dissented.
“The tariffs at issue here may or may not be wise policy. But as a matter of text, history, and precedent, they are clearly lawful,” Kavanaugh wrote in the dissent.
The majority did not address whether companies could get refunded for the billions they have collectively paid in tariffs. Many companies, including the big-box warehouse chain Costco, have already lined up for refunds in court, and Kavanaugh noted the process could be complicated.
“The Court says nothing today about whether, and if so how, the Government should go about returning the billions of dollars that it has collected from importers. But that process is likely to be a ‘mess,’ as was acknowledged at oral argument,” he wrote.
The tariffs decision doesn’t stop Trump from imposing duties under other laws. While those have more limitations on the speed and severity of Trump’s actions, top administration officials have said they expect to keep the tariff framework in place under other authorities.
