The Court That Broke the Trade War:
SCOTUS Strikes Down Trump's Tariffs 6–3

On February 20, 2026, the Supreme Court of the United States did something that presidents, trade lawyers, and importers had argued was impossible under the political conditions of the moment: it told Donald Trump no. In a 6–3 ruling in Learning Resources Inc. v. Trump, the court struck down the legal cornerstone of his second-term trade agenda — the sweeping tariff regime imposed under the International Emergency Economic Powers Act — and declared it unconstitutional. The immediate fallout has been staggering. The long-term consequences are only now coming into focus.

The majority opinion, written by Chief Justice John Roberts and joined by Justices Sotomayor, Kagan, Jackson, Gorsuch, and Barrett, rests on a deceptively simple legal argument. The administration had claimed that two words in IEEPA — 'regulate' and 'importation' — gave the president unlimited power to impose tariffs on any country, at any rate, for any duration. Roberts rejected that claim with uncharacteristic bluntness.

Roberts applied the 'major questions doctrine' — a legal principle the conservative-majority court has invoked repeatedly in recent years — to hold that when a president claims sweeping authority over a domain of vast economic significance, Congress must have spoken clearly to authorize it. IEEPA never mentioned tariffs or duties. Roberts noted that every other major tariff statute in American history had done so explicitly. The absence was fatal to the administration's case.

The president's reaction was immediate and characteristically unfiltered. He called the ruling 'a disgrace to the Constitution.' He singled out Justices Neil Gorsuch and Amy Coney Barrett — both of whom he had personally appointed — saying they 'sicken me' for joining the majority. He threatened to challenge the court's authority and pledged to restore the tariffs by any legal means available.

Within 96 hours, the White House pivoted from fury to improvisation. Trump invoked Section 122 of the Trade Act of 1974, a rarely-used statute that allows the president to impose global tariffs of up to 15% for up to 150 days to address balance-of-payments deficits — without needing to cite a national emergency. The initial announcement was 10%, then raised to 15% within hours. The replacement tariff is narrower, more legally constrained, and already under legal challenge: a coalition of 24 states has sued, arguing that the conditions required for Section 122 are not met.

The most consequential and least-discussed dimension of the ruling is what happens to the money. Since Trade War 2.0 began in 2025, the federal government has collected over $160 billion in IEEPA tariffs from American importers — companies that paid duties on Chinese electronics, European automobiles, Vietnamese textiles, Mexican manufactured goods. The court struck down the legal basis for those collections. The question of refunds, however, was left unanswered.

Customs and Border Protection and the Treasury Department are now navigating a refund process with no modern precedent. Legal experts estimate that $100 billion to $130 billion in refunds may ultimately be owed. The mechanics are daunting: import records going back months, claims from thousands of companies, the legal question of who — the importer of record, or the downstream consumer who absorbed the cost — is entitled to recover. Some economists have noted that if even a fraction of that sum flows back into the economy, it would constitute one of the largest unplanned fiscal stimulus events in American history.

The ruling did not end the US trade war. It changed its legal architecture. Critically, the court left intact two other pillars of the tariff regime: Section 232 duties — imposed on national security grounds, primarily on steel and aluminum — and Section 301 tariffs targeting countries found to have engaged in unfair trade practices, primarily aimed at China. These remain in force. And the Trump administration moved quickly to expand them.

Within weeks of the SCOTUS ruling, the Office of the US Trade Representative opened Section 301 investigations into nearly 80 countries and economies — including China, Japan, India, Mexico, and all 27 EU member states. These investigations, which can take months but ultimately authorize substantial tariffs, are designed to rebuild on permanent statutory footing what IEEPA erected on emergency authority. The trade war is not over. It is being re-litigated, re-authorized, and re-weaponized through every available legal channel.

Global markets have spent the weeks since the ruling trying to price in a scenario that defies easy modeling: a president who lost in court, refused to accept it, and launched three simultaneous legal strategies to restore what was taken away. The S&P 500 has posted five consecutive weeks of declines since the ruling, losing 2.1% in the most recent session and sitting at its lowest level in seven months. The Dow fell nearly 800 points in a single week. The Nasdaq, sensitive to the tech sector's supply chain exposure to Asia, has fallen over 2%.

The market is not reacting to clarity — it is reacting to the absence of it. Corporate CFOs cannot plan supply chains when tariff rates may shift from 0% to 15% to something else entirely depending on which court rules on which challenge this month. The bifurcated trade landscape — where IEEPA duties are gone, Section 122 replacements are legally contested, and Section 301 investigations are underway — has created a planning paralysis that is arguably more damaging than any single tariff rate.

Beyond the economics, the ruling lands at a moment of profound constitutional tension. The Trump administration has argued repeatedly — across immigration, spending, and now trade — that the presidency holds vast inherent powers that courts should be reluctant to constrain. The SCOTUS ruling, backed by two of Trump's own appointees, is a direct rebuke of that theory. Roberts' majority opinion is being read, in legal circles, as a significant reassertion of congressional prerogative over economic policy — a ruling that could constrain not just Trump but any future president who reaches for broad emergency authority to reshape global trade.

The dissent, written by Justice Clarence Thomas and joined by Alito and Kavanaugh, argued that the majority had overstepped — that IEEPA's text was capacious enough to include tariff authority and that the major questions doctrine was being deployed as a weapon against executive action. The 6–3 split, crossing ideological lines, suggests this is not a purely partisan ruling — and that makes it harder for the administration to characterize it as judicial overreach.
