The ‍US Supreme Court has issued ​three decisions but did not decide the closely watched ‌dispute ​over the legality ‍of President Donald Trump’s global tariffs.

The court on Tuesday did not ​announce ‌the next date when ​it will issue rulings.

It does not announce ​in ​advance ​which rulings ​will be released on a given date.

US Trade Representative Jamieson Greer said ‍on Tuesday that Trump’s tariffs ​under the International Emergency Economic Powers ⁠Act are the “most appropriate” remedies to the trade situations that the United States faces.

Greer told ​a forum in Davos, Switzerland ‍that there were other options to impose new tariffs if the Supreme Court were to strike down the IEEPA tariffs but ​declined to ‌discuss them.

“The president chose to use IEEPA because ​it is the most appropriate to ‍the situations we’re facing,” Greer said.

“For the emergency like the ​trade ​deficit, for ​emergencies related to national ​security, it’s the most appropriate. So if we aren’t allowed to use that, there are other tools we can use, certainly, but IEEPA ‍is the most appropriate.”
