() A federal appeals court has reversed one of two rulings that block President Donald Trump’s tariffs.

A group of small-business owners sued the Trump administration over the tariffs, arguing that the president had overstepped his authority. The block was imposed by a New York-based court that handles trade cases before the block was lifted.

Victor Schwartz, the owner of wine importer VOS Selections and one of the plaintiffs in the lawsuit, appeared on ” Now” on Thursday to discuss the lawsuit and its impact on his business. Schwartz said the uncertainty surrounding tariffs has made managing his business “very challenging.”

Jeffrey Schwab, the attorney in the lawsuit, said the law Trump relied on to issue tariffs, the International Emergency Economic Powers Act of 1977 (IEEPA), does not allow the president to impose his “Liberation Day” tariffs. He added that the stay on the tariffs is only temporary while the appeal is reviewed.

“I knew even though I was so elated over the win, I knew it was not over,” Schwartz said.

Many of Trump’s other tariffs remain blocked under a separate ruling made by a federal judge in Washington, D.C.
