A US trade court has dealt a direct blow to Donald Trump’s latest tariff push, ruling that his 10% global import duties overstepped the law he used to impose them.

The US Court of International Trade ruled 2-1 against the across-the-board tariffs that took effect on 24 February, siding with small businesses that challenged the policy. The court found that a 1970s trade law did not justify such sweeping action, according to reports on the decision. One judge dissented, arguing it was too early to hand the plaintiffs a win.

The decision strikes at the legal foundation of broad, one-size-fits-all tariffs imposed under emergency-style trade powers.

The ruling lands at a tense moment in Trump’s wider trade strategy. Reports indicate he also set a new deadline for the European Union to carry out trade deal terms, warning that tariffs could rise to much higher levels if that does not happen. That threat suggests the administration still plans to use import taxes as a central tool, even as the court narrows its legal room to maneuver.

Key Facts

  • The US Court of International Trade ruled against Trump’s 10% global tariffs.
  • The court said a 1970s trade law did not justify across-the-board duties.
  • Small businesses brought the legal challenge and won in a 2-1 decision.
  • One judge dissented, saying the ruling came too soon.

For businesses, the case matters beyond this single tariff round. Small importers often absorb the first shock from broad duties, and this decision gives them a stronger argument that presidents cannot stretch old trade statutes to cover nearly every foreign product. It also raises a larger question about where courts will draw the line when the executive branch claims expansive authority over trade.

The next steps will likely determine how much this ruling changes in practice. Appeals could follow, and the administration may look for other legal routes to preserve or replace the tariffs. At the same time, Trump’s fresh warning to the EU shows that the political fight over trade is far from over. What happens now will shape not only prices and supply chains, but also the balance of power between the White House and the courts.
