President Donald Trump on Wednesday night asked the Supreme Court to quickly accept and rule on an appeal seeking to overturn lower court decisions that found most of his tariffs are illegal.
The request comes five days after the U.S. Court of Appeals for the Federal Circuit, in a 7-4 ruling, said that Trump overstepped his authority when he implemented the steep levies on virtually every country.
That decision threw a central pillar of Trump’s trade agenda into doubt.
Trump is asking the Supreme Court to hear arguments on his appeal in early November and issue a final decision on the legality of the disputed tariffs soon afterward, according to filings obtained by NBC News from the plaintiffs in the case.
Normally, the Supreme Court would take as long as early next summer to issue such a decision.
Treasury Secretary Scott Bessent, in a declaration attached to Trump’s request, said the appeals court ruling “gravely undermines the President’s ability to conduct real-world diplomacy and his ability to protect the national security and economy of the United States,” the filing noted.
Filings by Trump also say that “delaying a ruling until June 2026 could result in a scenario in which $750 billion-$1 trillion in tariffs have already been collected, and unwinding them could cause significant disruption.”
Trump used the International Emergency Economic Powers Act, or IEEPA, to impose steep levies on trading partners, declaring the United States’ federal deficit with other nations a national emergency.
But the appeals court said that “tariffs are a core Congressional power,” not a presidential authority.
“The core Congressional power to impose taxes such as tariffs is vested exclusively in the legislative branch by the Constitution,” the court said.
The appeals court paused its ruling from taking effect until Oct. 14, giving Trump time to ask the Supreme Court to hear his appeal, and the high court to potentially issue an indefinite stay of the decision until it resolves the appeal.
Jeffrey Schwab, senior counsel at the Liberty Justice Center, which represented plaintiffs who successfully sued to block the tariffs, in a statement said, “The government has now asked the U.S. Supreme Court to review this case. Both federal courts that considered the issue agreed that IEEPA does not give the President unchecked tariff authority.”
“We are confident that our legal arguments against the so‑called ‘Liberation Day’ tariffs will ultimately prevail,” Schwab said.
“These unlawful tariffs are inflicting serious harm on small businesses and jeopardizing their survival. We hope for a prompt resolution of this case for our clients.”
