Trump's New Tariffs Face Legal Firestorm as Experts Question Validity

New York, NY - In a move that has sent ripples through the global trade landscape, the Trump administration has implemented broad new tariffs on goods from over 80 countries. The administration cited the alleged failure of these nations to effectively prohibit forced labor practices as the justification for these sweeping measures. However, legal experts and affected businesses are raising serious questions about the legality and potential longevity of these tariffs, with some predicting they may not withstand judicial scrutiny.

The new duties were enacted under Section 301 of the Trade Act of 1974, a provision that has seen significant use, particularly during Trump's first term against China. Despite its history, some trade scholars argue that the current application of Section 301 is a departure from its intended purpose and could be challenged successfully in court. Peter Harrell, a visiting scholar at Georgetown University Law Center's Institute of International Economic Law, noted that this statute was "never intended for the president to just wholesale rewrite the tariff schedule" and impose "permanent" duties.

The legal challenges were swift, with two small businesses filing a lawsuit just hours after the tariffs officially took effect. The plaintiffs contend that the administration is leveraging Section 301 as a pretext to reinstate the very global tariff regime that the Supreme Court previously invalidated. This previous ruling, made on February 20, 2026, struck down Trump's use of the International Emergency Economic Powers Act (IEEPA) for imposing unilateral tariffs on a vast number of countries.

The lawsuit, lodged in the U.S. Court of International Trade, highlights the contentious timing, with the new Section 301 tariffs coming into force just as a previous set of duties, enacted under Section 122 of the same 1974 law and designed with an expiration date, lapsed. The plaintiffs argue that the administration's actions are an attempt to "preserve substantially the same broad tariff regime that this Court and the Supreme Court have held Congress did not authorize."

Despite these accusations, a senior administration official defended the move, stating that addressing forced labor has been a long-standing priority for President Trump and that the timing was intended "to avoid complexity." The Office of the U.S. Trade Representative had not immediately responded to requests for comment on the lawsuit.

The Liberty Justice Center, representing the plaintiffs, previously succeeded in a challenge against Trump's use of IEEPA. They assert that the administration "cannot preserve a predetermined global tariff policy simply by moving from one statute to another."

This sentiment is echoed by several trade experts. Kimberly Clausing, a professor of tax law at UCLA School of Law, believes the Section 301 tariffs are "clearly unlawful" and that the focus on forced labor is a "mere pretext for recreating the IEEPA tariff regime." She added that there is "no evidence linking this sort of trade measure to the supposed policy goal" of combating forced labor, though she acknowledged that court rulings can be unpredictable and time-consuming.

Alan Wolff, a senior fellow at the Peterson Institute for International Economics (PIIE), also expressed skepticism, writing that the Supreme Court would likely strike down these tariffs. He argues that the requirement for Section 301's retaliatory authority—that a country's actions must burden U.S. commerce—is not clearly met for the majority of the targeted nations.

However, not all experts share this view. Greta Peisch, former general counsel for the U.S. Trade Representative, suggested that the administration has followed the necessary legal procedures for Section 301 tariffs, noting that the statute offers significant flexibility. Andrew Siciliano, global and U.S. head of trade and customs at KPMG, indicated that due to Section 301's extensive history, the new tariffs "may be harder to unwind," advising businesses to plan accordingly.

As the legal battles unfold, the business community faces uncertainty, with the ultimate fate of these tariffs hanging in the balance.
