US court questions 10% tariffs
A U.S. Court of International Trade pressed judges to probe whether President Trump’s new 10% tariff on most imports can be justified simply by citing a large trade deficit, putting the administration’s legal theory under strain. (reuters.com). Judges challenged aspects of the challengers’ case while states and small businesses argue the measure sidesteps an earlier Supreme Court rebuke — turning tariff policy into active legal uncertainty that companies may have to price in.

A federal trade court spent hours on April 10 asking a basic question the Trump administration struggled to answer: how does a long-running U.S. trade deficit let a president slap a 10% tax on most imports from most countries? The hearing was in the U.S. Court of International Trade, and the tariff has been in effect since February 24. (reuters.com) The case exists because the Supreme Court already struck down an earlier round of Trump tariffs on February 20, 2026. In that ruling, the justices said the 1977 International Emergency Economic Powers Act did not give the president power to impose tariffs just by declaring a trade emergency. (supremecourt.gov) (nbcnews.com) So the White House came back with a different legal hook. Instead of using the emergency-powers law, it used Section 122 of the Trade Act of 1974, a narrower statute tied to a “large and serious” balance-of-payments problem. (nbcnews.com) (politico.com) That phrase is the whole fight. The judges pressed government lawyers on whether a normal trade deficit in goods is the same thing as a balance-of-payments deficit, which is a more technical measure of money flowing in and out of a country. (apnews.com) (reuters.com) Think of it as the difference between one store in your house spending more than it sells and the whole household running out of cash. The United States often runs a goods trade deficit while still attracting foreign investment, which is why the judges kept circling back to what Congress meant in 1974. (politico.com) (reason.com) The challengers are 24 mostly Democratic-led states and two small businesses. They argue the administration is trying to do indirectly what the Supreme Court already said it could not do directly: impose broad tariffs without a clear statement from Congress. (reuters.com) (nytimes.com) The judges did not give the challengers an easy day either. Reporting from the hearing says the panel questioned whether courts should second-guess the president’s economic judgment and whether the old 1974 law gives him more room than the plaintiffs admit. (apnews.com) (yahoo.com) One reason this case is bigger than one tariff rate is the Supreme Court’s modern rule for big executive actions. In West Virginia v. Environmental Protection Agency in 2022, the Court said agencies need clear congressional authorization before making decisions of vast economic and political significance. (supremecourt.gov) (law.cornell.edu) Tariffs on most imports easily qualify as a policy with economy-wide reach. If the trade court says Section 122 is too vague for that job, presidents may need Congress to pass a more explicit tariff law before trying something this broad again. That last step is an inference from the way the hearing and the Supreme Court cases line up. (reuters.com) (supremecourt.gov 1) (supremecourt.gov 2) For companies, the immediate problem is not just the 10% number. It is that import pricing now depends on a court fight over a statute written during the Nixon-era currency system, with judges still asking what one key phrase even means.
