The European Union has halted implementation of the trade deal it struck with the United States last year, with the bloc citing concerns over the ambiguity created by the U.S. Supreme Court's recent decision that struck down the bulk of President Donald Trump's tariffs.

According to The New York Times, EU International Trade Committee Chair Bernd Lange noted on February 23 that there's a range of levies for products in the original agreement that would be higher than the new 10% global tariffs Trump enacted immediately following the Supreme Court's ruling.

“This is so uncertain,” Lange said. “It’s unclear if there will be additional measures."

The original deal between the Trump administration and the EU would have capped tariffs on most products at 15%. However, negotiations between the EU and the U.S. at the time were centered around tariffs that the Supreme Court has since invalidated, leaving European officials questioning whether the framework of the deal remains legally or politically viable. Trump's new 10% global tariffs were also enacted under a Section 122 of the Trade Act of 1974, meaning that they can only remain in place for 150 days before requiring approval from Congress.

In a statement posted to his Truth Social platform on February 23, Trump warned trade partners not to "play games" in the wake of the Supreme Court's decision. Even so, those threats have failed to slow the widespread uncertainty brought on by the Supreme Court's decision, with India recently delaying scheduled trade talks with the U.S., and the EU announcing the pause on its own deal with the White House.
