A U.S. trade court on Wednesday blocked President Donald Trump's "Liberation Day" tariffs from going into effect, ruling that the president overstepped his authority by imposing across-the-board duties on imports from nations that sell more to the United States than they buy.

The Manhattan-based Court of International Trade said the U.S. Constitution gives Congress exclusive authority to regulate commerce with other countries that is not overridden by the president's emergency powers to safeguard the U.S. economy.

"The court does not pass upon the wisdom or likely effectiveness of the President’s use of tariffs as leverage. That use is impermissible not because it is unwise or ineffective, but because [federal law] does not allow it," a three-judge panel said in the decision.
