The court will examine whether Trump overstepped presidential authority by imposing sweeping tariffs under the International Emergency Economic Powers Act (IEEPA) of 1977.
The case questions the legal foundation of tariffs that have been a cornerstone of Trump’s economic and trade strategy, particularly during periods of heightened trade tensions.
Trump signals backup plans
Reacting to the legal challenge, Trump said his administration was prepared to pursue alternative legal mechanisms if the Supreme Court blocks the use of IEEPA.
He alleged that opposition to the tariffs was influenced by pro-China interests, arguing that resistance to tariffs effectively benefits Beijing, as per a report by News18.
Trump warned that an adverse ruling would have wide-ranging consequences, including the potential obligation to return “hundreds of billions” of dollars collected through tariffs.

Such an outcome, he said, would disrupt ongoing trade negotiations and create significant financial and administrative complications, as per News18.
He also pointed out that while no previous president had deployed IEEPA in this manner, his administration was considering other statutory routes, including Section 232 of US trade law, which has previously been used to impose tariffs on steel and aluminium.
‘Experts were 100% wrong’, says Trump
Defending his policy, Trump dismissed criticism that tariffs raise prices for American consumers. He argued that the costs are borne by foreign governments and intermediaries, not US buyers.
“Every prediction by critics failed. Tariffs aren’t paid by American consumers, they’re paid by foreign nations and middlemen. The so-called experts were 100% wrong and Trump was right,” he said, as per News18.
Trump further claimed that the tariff regime contributed to a 27% reduction in the federal budget deficit over a short period and played a role in curbing inflation.
Warning of a ‘complete mess’
In a post on his Truth Social platform dated January 12, Trump escalated his warning, stating that a ruling against the government would trigger massive repayment obligations.

“The actual numbers that we would have to pay back… would be many Hundreds of Billions of Dollars,” he wrote, adding that when related investment commitments were considered, the figure could run into trillions.
“It would be a complete mess… Remember, when America shines brightly, the World shines brightly… if the Supreme Court rules against the United States of America on this National Security bonanza, WE’RE SCREWED!” he concluded with a stark assessment of the stakes involved.
