The U.S. Court of International Trade is now at the center of a high-stakes legal battle that could redefine the boundaries of presidential authority in trade policy. Five small businesses from across the country have filed a lawsuit challenging President Donald Trump’s recent ‘Liberation Day’ tariffs, arguing that the administration overstepped its authority under the International Emergency Economic Powers Act (IEEPA). The court’s decision could have sweeping implications for future executive actions involving economic emergencies and import duties.

Background of the ‘Liberation Day’ Tariffs
The lawsuit stems from Executive Order 14257, signed by President Trump on April 2, which imposed a 10% baseline tariff on nearly all imports. The order was framed as a move to restore American sovereignty and reduce dependence on foreign goods, coinciding with the administration’s declaration of “Liberation Day.” In some cases, such as Chinese imports, the tariffs soared to as high as 145%.
To justify the order, the administration cited national security threats stemming from the U.S. trade deficit. By invoking IEEPA, the president argued that the deficit presented an “unusual and extraordinary threat” to the country’s economic stability, allowing emergency action. The plaintiffs, however, claim the use of IEEPA in this context is a misapplication of the law.
The Plaintiffs and Their Legal Argument
The plaintiffs in the case include a diverse group of American small businesses: V.O.S. Selections (a wine importer), Genova Pipe (a manufacturer), MicroKits LLC (an educational electronics firm), FISH USA (a fishing supply retailer), and Terry Cycling (a cycling apparel company). Represented by the Liberty Justice Center, they argue that the tariffs are causing immediate and measurable harm, including rising costs, disrupted supply chains, and pricing instability.
Their legal claim centers on the contention that trade deficits do not meet IEEPA’s threshold for an “emergency.” The law, passed in 1977, was designed to give the president powers to address genuine international crises, not to enact sweeping economic changes unilaterally. The plaintiffs are seeking a preliminary injunction to halt the tariffs while the case proceeds, arguing that unchecked executive authority in trade matters undermines the constitutional balance of powers.
The Government’s Defense and Broader Implications
The U.S. Department of Justice is defending the order, asserting that the president has broad discretion under IEEPA and that economic threats like trade deficits fall within its scope. Additionally, the DOJ argues that none of the plaintiffs have actually paid the tariffs yet, weakening their claim of direct harm.
Legal scholars are closely watching the case due to its potential to clarify—or redefine—the scope of presidential power in emergency economic matters. A ruling against the administration could constrain future presidents’ ability to use IEEPA for nontraditional emergencies. Conversely, a verdict in favor could set a precedent allowing wide-ranging economic actions under broad emergency declarations.
What’s Next in Court
The Court of International Trade is expected to rule on the request for a preliminary injunction in the coming weeks. That decision will determine whether the tariffs remain in place during the trial. A full hearing on the constitutional and statutory questions at stake will follow later this year.
In the meantime, additional lawsuits from other states and businesses are lining up, raising the possibility of a consolidated or extended legal fight. Regardless of the outcome, the case is poised to shape future debates around trade authority, emergency powers, and the balance between Congress and the executive branch.
