25 States Sue Trump Over Tariffs, Testing the Outer Limits of Presidential Power
New York pays $47 million more per year for steel girders used in state highway projects under the current tariff regime. California estimates a $112 million spike in costs for imported electronics destined for public school districts. Those are not hypothetical projections, they are line items buried in a complaint filed by 25 state attorneys general in federal court this month, and they illustrate why this lawsuit is not a symbolic protest. It is a balance sheet fight dressed in constitutional language.
The coalition, led by Democratic attorneys general from New York and California, argues that the White House has converted trade policy into a backdoor federal sales tax that only Congress has the power to levy. At the center of the complaint is the administration's use of Section 232 of the Trade Expansion Act of 1962 and Section 301 of the Trade Act of 1974, statutes written during the Cold War to address narrow national security threats, to impose duties ranging from 10% to 25% on billions of dollars of imports from major trading partners. The plaintiffs claim the phrase "national security" has been stretched beyond recognition, functioning now as an all-purpose justification for economic policy that affects everything from construction materials to consumer electronics.
Why "arbitrary and capricious" matters
The lawsuit relies heavily on the Administrative Procedure Act, which requires federal agencies to follow a formal process when issuing rules with broad impact. That process includes public notice, a comment period, and a written rationale explaining why the rule is necessary. The states argue the tariffs bypassed all three. Duties were announced, not proposed. No comment window opened. The economic analysis released alongside the orders was, in the complaint's phrasing, "conclusory", meaning it stated outcomes without showing work.
This is not an abstract procedural complaint. When a state government signs a contract to build a bridge, it budgets based on predictable input costs. A 20% tariff on imported steel, imposed mid-project with no warning, forces either cost overruns or project delays. The APA was designed to prevent exactly that: regulatory whiplash that leaves public and private actors unable to plan.
The Major Questions Doctrine enters the frame
The states are also invoking a relatively recent Supreme Court precedent known as the Major Questions Doctrine. The doctrine holds that when an agency claims the authority to make decisions with vast economic or political significance, it must point to clear Congressional authorization, not vague statutory language. The court applied this reasoning in 2022 to block the EPA's sweeping climate regulations and again in 2023 to strike down student loan forgiveness. Both cases turned on the idea that agencies cannot discover new, transformative powers in old, general statutes.
Here, the plaintiffs argue, the administration is claiming the power to reshape the entire U.S. import economy, affecting an estimated $3,000 per household annually, based on statutes written when trade with China was negligible and "national security" meant Soviet steel, not semiconductor supply chains. If those statutes truly grant such sweeping authority, the states contend, the Supreme Court's recent precedents suggest Congress needs to say so explicitly.
Standing and the state budget angle
For this case to proceed, the states must prove they have standing, that the tariffs harm them directly, not just the people who live within their borders. The complaint zeroes in on two categories of injury: lost tax revenue from businesses squeezed by higher input costs, and increased procurement expenses for state-funded infrastructure. Both are concrete, dollar-denominated harms that courts have historically recognized as sufficient to grant states the right to sue.
The administration's defense rests on a different constitutional provision: Article II, which gives the President authority over foreign affairs. Trade policy, the argument goes, is inherently part of diplomacy, and courts have long deferred to the executive branch in that domain. That deference has been nearly absolute when "national security" is invoked. Whether the current Supreme Court maintains that tradition, or applies its newer skepticism about executive overreach, will determine whether this lawsuit becomes a footnote or a landmark.
