Businesses challenge the legality of new trade levies after the Supreme Court invalidated earlier tariffs imposed by the administration.

Several U.S. companies have filed a lawsuit against President Donald Trump over the imposition of new 15 percent tariffs, intensifying a growing legal battle over the administration’s trade policy.

The nonprofit Liberty Justice Center announced Monday that it filed the complaint before the U.S. Court of International Trade on behalf of a group of businesses led by Burlap & Barrel, an e-commerce spice company, and Basic Fun!, a toy manufacturer. Both firms had previously taken part in litigation challenging Trump-era tariffs.

The case adds to a separate lawsuit filed last week by a group of Democratic attorneys general, signaling a widening judicial dispute over the legality of the new levies. The legal challenge comes weeks after the U.S. Supreme Court struck down tariffs previously imposed by the administration under the International Emergency Economic Powers Act (IEEPA), according to statements shared on the social media platform X.

Earlier tariffs introduced by Trump were based on the 1977 emergency powers law. The Supreme Court ruled that the legislation did not authorize the unilateral imposition of tariffs by the executive branch.

Following that decision, the administration invoked Article 122 of the Trade Act of 1974 to justify the new 15 percent duties.

However, the law stipulates that such tariffs cannot be maintained indefinitely without authorization from Congress. Trump has explicitly rejected seeking legislative approval. According to the law firm’s statement, the president does not intend to request authorization from lawmakers.

“Proud to fight alongside our clients as they defend not only their own businesses and customers, but also a fundamental constitutional principle: NO president has the power to tax the American people on his own,” the group wrote on X.

At the same time, U.S. courts are facing another major dispute linked to tariffs already collected. Companies affected by those measures have requested refunds totaling 166 billion dollars after the Supreme Court confirmed their invalidity.

Multiple firms have joined claims seeking compensation, a development that could create a significant financial burden for the federal government if courts rule in favor of the companies.

The lawsuits suggest that the administration’s tariff policy could remain the subject of prolonged legal scrutiny as businesses and state officials challenge the limits of presidential authority in trade policy.
