Trump warns justices: striking down tariffs would force billions refunded

President Donald Trump urged the Supreme Court to preserve his broad tariff program, warning that a ruling against him would leave the United States "financially defenseless" and pose the "biggest threat in history to United States National Security," while the government faces the prospect of refunding "some of the billions" in duties it has collected.

The case centers on Mr. Trump's use of the 1977 International Emergency Economic Powers Act to impose so-called "Liberation Day" tariffs that, by one characterization, range from 10 percent to 50 percent on imports from virtually all U.S. trading partners. Plaintiffs include "a number of small businesses and a group of US states" and businesses described by the administration as having China ties. If the justices reject the emergency-based authority, the government could be forced to return substantial sums, a process Justice and administration officials have warned could take years to untangle.

Trump has amplified the stakes in public posts and rallies. On Truth Social he wrote "We would be financially defenseless," and the BBC quoted an earlier post reading "WE'RE SCREWED." At a campaign rally in Georgia he insisted "I have the right to put tariffs on for national security" and complained about waiting for a court decision. The Associated Press reported Trump warned the country could be rendered "defenseless" and possibly "reduced to almost Third World status" if the tariffs are struck down.

Legal debate before the court has focused on whether the president exceeded his authority by invoking IEEPA rather than relying on traditional congressional trade powers. During oral argument justices sounded skeptical; Justice Neil Gorsuch "signaled he was troubled by the idea that Congress could give away its power over taxes to the president." Newsweek identified a likely coalition to rule against the administration that could assemble the court's three liberal justices and at least two conservatives, naming Justices Amy Coney Barrett, Neil Gorsuch and Chief Justice John Roberts as among those appearing most likely to disagree with the administration's position.

The administration has signaled contingency plans. Treasury Secretary Scott Bessent said the United States has "other options" if the court rejects the emergency route. Legal and policy options cited in reporting include reusing Section 301 authority, which in Mr. Trump's first term was used against China and "has no limits on the size" of tariffs though those measures expire after four years and can be extended; a separate law allowing tariffs of up to 15 percent for 150 days; and an unnamed authority dating from the Great Depression.

Critics say the sweeping duties, described by opponents as a tax on importers, have pushed up inflation, deprived American firms of inputs and invited retaliatory tariffs that hurt U.S. exporters. That economic friction carries public health and equity implications: higher import costs can translate into more expensive medical devices, drugs and basic goods, worsening affordability for low-income families and straining hospitals and clinics already managing tight budgets.

The dispute has also provoked political pushback. The House passed a resolution to terminate national emergency measures used to impose tariffs on Canada, with six Republicans crossing party lines to vote with Democrats. Meanwhile the administration has signaled plans to roll back some metals duties, including steel and aluminum, in part to blunt affordability concerns.

With the Supreme Court poised to rule, the decision will decide not only a legal limit on presidential economic emergency powers but whether billions in tariff revenues must be returned and how swiftly the United States can stabilize trade policy without deepening costs for workers, patients and communities that depend on affordable imports.
