By Nate Raymond May 15 (Reuters) - Amazon.com Inc was sued on Friday by consumers seeking refunds for costs passed on to them in the form of higher prices as a result of tariffs the U.S. Supreme Court later concluded had been unlawfully imposed by President Donald Trump.

A federal court has ruled against the new global tariffs that President Donald Trump imposed after a stinging loss at the Supreme Court.

The president has reworked his tariffs repeatedly — sometimes because they have been declared illegal — with more updates still to come.

A federal appeals court has temporarily paused a ruling that declared President Donald Trump’s latest global tariffs unlawful, as the judges weigh the administration’s request to let officials continue to collect the levies while the legal fight is ongoing.

The administration is suspending tariff-rate quotas on all beef-exporting nations; beef prices have climbed steadily since Trump took office.

A panel of federal judges on Thursday found President Trump had violated the law when he imposed a 10 percent tariff on most U.S. imports, dealing yet another legal setback to the White House in its efforts to wage a trade war without the express permission of Congress.

A panel of judges for the Court of International Trade ruled 2-1 that Trump couldn't use the 1974 Trade Act to impose his 10% levy.

The Court of International Trade has struck down a second round of global tariffs ordered by President Trump, after his earlier import taxes were outlawed by the U.S. Supreme Court.

US President Donald Trump said Chinese leader Xi Jinping was “extremely hard to make a deal with” in a comment that comes as frictions rise between the two countries, weeks after they reached an agreement to de-escalate trade tensions.

Trump threatened to impose 25% tariffs on cars and trucks imported from the European Union by accusing those countries of violating a trade deal.
