Two small U.S. businesses filed a lawsuit on Friday against the Trump administration, challenging newly announced Section 301 tariffs on dozens of trading partners.
The legal action comes just one day after President Donald Trump’s administration unveiled the expanded tariff regime, marking an immediate escalation in the dispute over trade policy enforcement.
The lawsuit builds on a recent Supreme Court ruling that declared the continued imposition of these specific tariffs unlawful.
By taking legal action, the plaintiffs are seeking to enforce the high court’s decision and halt the collection of duties that have already begun to impact import costs for smaller enterprises.
This move signals that the judicial branch’s check on executive trade authority is moving from theoretical precedent to active litigation.
The legal challenge adds to a growing chorus of opposition from the private sector.
