Donald Trump's trade tariffs have been declared illegal in an Appeals Court ruling which the US President has said could be a "total disaster" for America.
The court ruled Mr Trump had no legal right to impose the global tariffs, and he was not legally allowed to declare national emergencies.
However, the tariffs have been allowed to stay in place until October 14 in order to give the White House the opportunity to appeal to the US Supreme Court.
The President slated the ruling on social media, saying removing the tariffs would be a "total disaster" for America.

Reiterating that all of the tariffs are "still in effect", Mr Trump's post said: "Today a Highly Partisan Appeals Court incorrectly said that our tariffs should be removed, but they know the United States of America will win in the end.
"If these tariffs ever went away, it would be a total disaster for the country.
"It would make us financially weak and we have to be strong."
He added: "If allowed to stand, this decision would literally destroy the United States of America.

"At the start of this Labor Day weekend, we should all remember that tariffs are the best tool to help our workers, and support companies that produce great made in America products."
It is not the first time Mr Trump's tariffs have been blocked by courts in the United States.
Earlier this year a US federal court in New York ruled the President had overstepped his authority and it blocked the majority of the import taxes from going into effect.
However, the tariffs were quickly reinstated.
In justifying his global tariffs, the US President cited the International Emergency Economic Powers Act (IEEPA).

He declared the US trade deficit and immigration among the country's national emergencies.
However, in its ruling on Friday, the court said: "It seems unlikely that Congress intended, in enacting IEEPA, to depart from its past practice and grant the President unlimited authority to impose tariffs."
It added: "[The US law] bestows significant authority on the President to undertake a number of actions in response to a declared national emergency.
"But none of these actions explicitly include the power to impose tariffs, duties, or the like, or the power to tax."
Mr Trump has said he will appeal the decision and plans to take the fight all the way to the Supreme Court.
The global trade war was first sparked by the US President when he hit nearly every country with at least a ten per cent tariffs on their exports to the US.
Certain countries, such as Mexico received a higher tariff of 25 per cent because the President said it was needed to stop the flow of illegal immigrants.
