In 2026, the Supreme Court delivered a landmark decision in Learning Resources v. Trump, striking down President Trump’s IEEPA tariffs and curtailing executive power over trade policy more significantly than any ruling in nearly half a century. The ruling temporarily reined in the tariff chaos caused by the president’s “Liberation Day” announcement of April 2, 2025, as well as the numerous executive proclamations and orders the White House issued to authorize sweeping tariffs on more than eighty countries. The ruling also reaffirmed the importance, under the U.S. Constitution, of the principle of separation of powers: the idea that the Constitution vests core authority over tariff policy exclusively in Congress and that the president has no independent or inherent power to levy tariffs during peacetime or through emergency declarations without a clear, specific statute passed by Congress.
Moreover, the Supreme Court further sculpted the Major Questions Doctrine by addressing presidential emergency powers, the limits of executive authority, and statutory interpretation. President Trump’s unilateral, heavy-handed use of tariff policy pursuant to IEEPA, in the Supreme Court’s view, was an example of executive overreach, undermining the Framers’ intent under the Constitution, the authority of Congress, and the responsibility of the Executive Branch to remain within the bounds of the law.
However, the road to rebuilding America’s tariff wall is only just beginning. The Trump administration is actively searching for new legal footing under alternative statutes to impose sweeping tariffs on imports as it seeks to replace the IEEPA tariffs with new levies, including those authorized under Sections 301, 122, 232, and 338. The use of some of these statutes is unprecedented, and the maintenance of high tariff rates on approximately 99.4% of all imports into the country is reminiscent of the beggar-thy-neighbor trade policies of the 1930s, when the global economy collapsed and widespread tariff retaliation from Europe and other countries sparked a global trade war.
The legal implications of the Learning Resources decision, and of the imposition of new tariffs under the limited trade authority delegated by Congress through these various statutes, are significant and will likely keep the courts occupied with legal challenges in the near future. How the courts will treat these challenges remains uncertain, but an early indication from the Supreme Court in Learning Resources suggests that it views the use of some of these alternative statutes more favorably. In the meantime, the Learning Resources ruling stands as a bulwark against the excesses of executive power and in favor of efforts to rein in the chaos of America’s “ready, fire, aim” tariff policies.
