Donald Trump Says America Is ‘Doomed’ If He Loses Supreme Court Ruling On Tariffs

President Donald Trump has warned that the United States would face severe consequences if the Supreme Court rules against his administration in a major legal challenge to his broad “reciprocal” tariffs imposed under emergency powers.

In a post on Truth Social, Trump said an unfavorable ruling could cost the country enormous sums of money, forcing refunds of collected tariffs and undermining U.S. leverage in global trade negotiations.

The case focuses on whether Trump lawfully relied on the International Emergency Economic Powers Act (IEEPA) to impose wide-ranging import duties. While the law allows action during national emergencies, it has rarely been used to justify sweeping tariffs.

These tariffs were among Trump’s most aggressive trade actions and are central to his economic strategy. Businesses, foreign governments, and financial markets are closely watching the case due to its potential impact on prices, supply chains, and trade policy.

Lower courts have already ruled that Trump exceeded his authority under IEEPA, prompting the Supreme Court to take up the case. A decision is expected soon after arguments were heard in November.

If the tariffs are struck down, the federal government could be required to refund more than $100 billion to importers. Treasury officials have downplayed the financial risk, saying the government could handle any repayments.

Trump argues the broader damage would go beyond refunds, warning that limiting presidential tariff powers would weaken national security and economic influence. The ruling could also shape how future presidents use emergency powers in trade disputes.
