U.S. President Donald Trump has sharply criticised the Supreme Court of the United States after it struck down his use of emergency powers to impose sweeping tariffs, calling the decision “extremely disappointing” and “ridiculous.”

In a 6-3 ruling, the court held that the International Emergency Economic Powers Act (IEEPA) did not grant the president authority to impose tariffs, dealing a significant blow to Trump’s trade strategy.

Responding to the verdict, Trump insisted the ruling did not invalidate tariffs altogether but only blocked his specific reliance on IEEPA.

He said previously imposed tariffs would remain “in full force” and pledged to pursue alternative legal avenues.

“This tariff gave us tremendous national security,” Trump said, adding that the court’s decision is ridiculous.

He argued that the ruling effectively stated he could not “charge one dollar to any country,” while still allowing him to impose sweeping trade restrictions.

“I can destroy the trade, I can destroy the country. I’m even allowed to impose a foreign country-destroying embargo. I can embargo. I can do anything I want, but I can’t charge $1 because that’s not what it says,” he said.

“How ridiculous is that?”

The president alleged that the court had come under political pressure and that such decisions were an insult to the nation.

He added that while the ruling acknowledged aspects of his administration’s performance, it unfairly curtailed executive authority.

Trump defended his tariff policy as vital to economic leverage and global stability. He reiterated his claim that tariffs had helped prevent five out of eight wars, including a potential conflict between India and Pakistan that he described as being “on the verge of becoming a nuclear war.”

He also praised Pakistan’s Prime Minister Shehbaz Sharif, saying the premier credited him during a Peace Board meeting with saving 35 million lives by helping defuse tensions.

Announcing immediate action, Trump said he would sign an executive order imposing a 10 per cent global tariff under Section 122 of the Trade Act of 1974. The provision, he said, would allow him to protect U.S. interests without relying on IEEPA.

“We have alternatives,” Trump said, “could be more money. We’ll take in more money and and we’ll be a lot stronger for it.”

“Today, I will sign an order to impose a 10% global tariff under Section 122, over and above our normal tariffs already being charged,” Trump said.

He also said all national security tariffs under Section 301 remain in place, and several investigations will be initiated.

Trump said the 10 per cent tariffs he just announced will be for a period of about five months.

“During that period of about five months, we are doing the various investigations necessary to put fair tariffs, or tariffs period, on other countries,” Trump told reporters. 

Asked whether the duties will be for only 150 days or indefinitely, the U.S. president said, “We have a right to do pretty much what we want to do, but we’re going to charge it starting effectively. I think it’s three days from now.”

Trump said foreign countries are celebrating the ruling, but it won’t last long.

“Foreign countries that have been ripping us off for years are ecstatic. They’re so happy, and they’re dancing in the streets, but they won’t be dancing for long, that I can assure you,” said Trump.

He said, without evidence, the Supreme Court has been “swayed by foreign interests and a political movement that is far smaller than people would ever think.”

The Supreme Court’s majority opinion stated that while IEEPA permits the president to regulate importation during national emergencies, it does not explicitly authorise the imposition of tariffs, emphasising that such significant economic actions require clear congressional approval.
