An appeals court in Washington has ruled that all of the tariffs United States President Donald Trump imposed because he declared a national emergency are illegal.
But Trump immediately said he will file an appeal to the Supreme Court where a majority of the justices have made rulings in favour of Trump.
The tariffs on Canadian steel and aluminum are not included in the appeal court decision because they were imposed under the Trade Expansion Act.
The 7-4 decision by the U.S. Court of Appeals for the Federal Circuit will not take effect until October.
