More than 1,000 American companies are anxiously awaiting an announcement.
Among them are sports companies Reebok and Puma, which, together with tire company Goodyear, have pursued the case in court and sought compensation for the global tariffs that Donald Trump announced last year in connection with what was called "Liberation Day."
The background is that Donald Trump wanted to move very quickly and very broadly with tariffs. He then chose to use a law that has not previously been used for this purpose, says Elisabet Kopelman, a U.S. economist at SEB, to TT.
Moved on
The companies have been found right in lower courts and the matter has been forwarded to the Supreme Court, which announced on Friday afternoon that no decision would be announced today.
The Supreme Court never announces in advance which decisions will be made public, only that judgments are possible on what is called a "decision day".
Trump has called it "a national security disaster" if the Supreme Court were to choose to go against him.
The arguments from the administration are that it is very important for fiscal reasons and that it would jeopardize fiscal stability in the United States if it were forced to pay back this money, Kopelman points out.
If the court were to declare the tariffs illegal, there is a risk of having to pay back over $150 billion, reports the Reuters news agency.
If the Supreme Court were to go against Trump, it would be a gigantic prestige defeat for the president. However, Elisabet Kopelman does not believe that this means the end of Trump's tariff policy.
"They are obviously prepared for this to happen and have said they have alternatives," she says.
According to the Financial Times, which spoke to diplomats and trade lawyers, Trump is prepared to launch a new wave of tariffs, based on alternative legislation.
Not entirely clear
Kopelman highlights, among other things, a paragraph that deals with the current account crisis.
Using this as a basis, tariffs of up to 15 percent can be issued for a maximum of 150 days to address large and serious deficits in the U.S. current account.
It is not certain that there will be a clear yes or no from the Supreme Court. U.S. Treasury Secretary Scott Bessent has said that a mixed bag of decisions is expected.
