Five small businesses calledPresident Donald Trump's tariffs an illegal power grab andurged a federal trade court to block them, but government lawyers contend presidents have beenimposing tariffssince the country's infancy. The U.S.Court of International Trade already rejected a requestfrom the businesses on April 22 to block the tariffs temporarily while the case is litigated. Judges Gary Katzmann, Timothy Reif and Jane Restani heard arguments May 13 in New York about whether to decide the case quickly, without gathering more evidence. Trump imposed 10% tariffs on imports from around the world on April 2, with higher rates on countries that sellmore to the U.S. than they import, such as China. Trump has argued the tariffs will generate billions of dollars in revenue while also encouraging companies to increase manufacturing in the U.S. The companies represented by the Liberty Justice Center, a nonprofit public-interest litigation firm, contend Trump has no authority to impose unlimited, unreviewable tariffs in any amount on any country at any time. "The president's imposition ofso-called 'Liberation Day' tariffsrepresents an unprecedented and unlawful expansion of executive authority," said Jeffrey Schwab, a lawyer representing the businesses. "This is not what Congress intended."

Hamilton said the courts have never reviewed political decisions such as declarations of national emergencies such as the one Trump declared under the International Emergency Economic Powers Act. And the Senaterefused to blockTrump's tariffs in an April vote. "These are questions decided by the political branches in the end," Hamilton said of tariff decisions made by Congress or the president. Judge Jane Restani asked how the court could gauge whether the tariffs are responding to an "unusual" or "extraordinary" situation. "How would the court draw that line?" Restani asked. "'You know it when you see it' doesn't work. Give me some words."

"I'm asking this court to be an umpire and to call a strike," Schwab said. "You're asking me, 'Where's the strike zone? Is it at the knees or slightly below the knees?' I'm saying it's a wild pitch and it's on the other side of the batter and it hit the backstop so we don't need to debate the difference." Justice Department lawyers said Congress empowered presidents to conduct foreign affairs and regulate trade, including with tariffs since 1794. But Schwab argued regulating trade means inspections rather than taxing imports. Judge Gary Katsmann noted that theU.S. Supreme Courtupheld identical language in a 1974 ruling that allowed former President Richard Nixon's surcharges on imports when the country went off the gold standard. More:Trump says the ultimate fruits of tariffs will be worth the pain. Experts disagree. "Why do you suggest we come to an opposite conclusion when the statutory language is identical?" Katsmann asked. Schwab said the court needed to take a fresh look because the law Trump cited to "regulate" international trade was approved later. "The term regulate does not mean the power to tax or tariff," Schwab said. Judge Timothy Reif said regulation could mean tariffs. "'Regulate' could mean a lot of different things, so could it mean tariffs," Reif said.
