Supreme Court Strikes Down Trump Tariffs, Invoking ‘Major Questions Doctrine’

A legal doctrine previously used to challenge Biden-era environmental policies has now resulted in a significant setback for a key component of former President Donald Trump’s economic agenda.

In a 6-3 decision on Friday, the Supreme Court ruled that the president lacked the authority to impose tariffs on a wide range of foreign goods under a law intended for national emergencies. The case, Learning Resources v. Trump, centered on the application of the “major questions doctrine.”

The ‘Major Questions Doctrine’ Explained

Chief Justice John Roberts, writing for the majority, found that the federal government had violated the major questions doctrine. This doctrine asserts that Congress must explicitly authorize executive action on issues of substantial economic or political significance. The Court determined that the International Emergency Economic Powers Act (IEEPA) did not provide the necessary congressional authorization for the broad tariffs imposed by the Trump administration.

Roberts previously invoked the same doctrine in 2022 to invalidate an Obama-era climate rule, demonstrating its growing influence in the Court’s jurisprudence.

Dissenting and Concurring Opinions

Even as agreeing with the outcome, Justice Elena Kagan, leading a concurring opinion joined by the court’s liberal justices, argued that the case could have been decided on more traditional statutory interpretation grounds. She criticized the increasing use of the major questions doctrine as an impediment to effective governance, referencing her dissent in West Virginia v. EPA.

Conservative Justice Neil Gorsuch also filed a concurring opinion, urging Kagan and her colleagues to reconsider their stance on the doctrine, quoting from her 2022 dissent to highlight its potential benefits.

Three justices – Brett Kavanaugh, Samuel Alito, and Clarence Thomas – dissented, arguing that Congress had implicitly authorized the president to impose tariffs and that the major questions doctrine was not applicable in matters of foreign affairs. Kavanaugh, in his dissenting opinion, characterized Roberts’s application of the doctrine as a “significant change” and questioned its future application in similar cases.

The Case Background

The lawsuit was brought by small businesses, led by Learning Resources and V.O.S. Selections, along with a coalition of Democratic-led states. Recent York Attorney General Letitia James hailed the Supreme Court’s decision as a “critical victory for the rule of law and our economy.”

The Trump administration had justified the tariffs by citing two national emergencies: the flow of illicit drugs across U.S. Borders and perceived “lack of reciprocity” in international trade. However, the Court found that IEEPA, enacted in 1977, does not explicitly authorize the imposition of tariffs and had not been used for that purpose previously.

Implications and Future Outlook

Justice Gorsuch, in his concurrence, suggested that upholding the tariffs could have paved the way for future administrations to expand executive power excessively, potentially allowing a Democratic president to impose tariffs on gas-fueled vehicles to address climate change.

Trump publicly rebuked the court’s ruling, expressing his disappointment and identifying potential alternative avenues for imposing tariffs.
