SUPREME COURT CURBS TRUMP'S EMERGENCY TARIFF POWER IN LANDMARK 6-3 RULING
SUPREME COURT CURBS TRUMP'S EMERGENCY TARIFF POWER IN LANDMARK 6-3 RULING
Justices ruled that IEEPA does not authorize the president to impose tariffs, but the decision did not eliminate other congressional trade authorities — and the administration quickly turned to them.
WASHINGTON, D.C. — Updated September 10, 2026
FACT-CHECK AT A GLANCE
• TRUE: On February 20, 2026, the Supreme Court ruled 6-3 in Learning Resources, Inc. v. Trump that the International Emergency Economic Powers Act (IEEPA) does not authorize presidential tariffs.
• TRUE, WITH NUANCE: Chief Justice John Roberts and Trump appointees Neil Gorsuch and Amy Coney Barrett were in the six-Justice majority. Sotomayor, Kagan and Jackson also agreed with the result.
• IMPORTANT DISTINCTION: The six Justices did not rely on one identical legal theory. Roberts, Gorsuch and Barrett used major-questions reasoning; Kagan, Sotomayor and Jackson said ordinary statutory interpretation was enough.
• OVERSTATED IF BROADENED: The ruling did not invalidate every Trump tariff or erase presidential trade authority. It invalidated tariffs imposed under IEEPA; other statutes such as Sections 122, 232, 301 and 338 can authorize tariffs or import restrictions under specified conditions.
• TRUE: Trump sharply criticized the ruling and the Justices in the majority, then announced a temporary 10% import surcharge under Section 122 of the Trade Act of 1974.
• CONSTITUTIONAL CONTEXT: Article I gives Congress the tariff and taxing power. Congress may delegate portions of that authority by statute, but the Court found that IEEPA was not such a tariff delegation.
A major Supreme Court decision cut off one of President Donald Trump's broadest legal routes for imposing tariffs, but it did not end his tariff agenda. In a 6-3 ruling issued February 20, the Court held that the International Emergency Economic Powers Act — a 1977 emergency statute better known as IEEPA — does not authorize a president to levy tariffs simply by declaring a national emergency.
The decision was unquestionably a major defeat for a central feature of Trump's second-term economic program. His administration had used IEEPA to impose sweeping duties tied both to drug-trafficking emergencies and to what it described as persistent trade deficits. But the most accurate reading of the ruling is narrower than some political summaries suggest: the Court did not declare presidential tariffs unconstitutional across the board, nor did it hold that Congress can never delegate tariff authority. It decided that Congress did not grant that particular power in IEEPA.
What the Supreme Court Actually Decided
The consolidated litigation involved Learning Resources, Inc. v. Trump and Trump v. V.O.S. Selections, Inc. The core legal question was simple to state but enormous in consequence: does IEEPA authorize the president to impose tariffs?
The Court's answer was no. The syllabus states the holding directly: "IEEPA does not authorize the President to impose tariffs." The majority emphasized that Article I gives Congress the power to impose taxes, duties and imposts, and that the executive branch has no inherent peacetime tariff power. A president therefore needs authority delegated by Congress to impose import duties.
That does not mean Congress must personally vote on every tariff rate. For generations, Congress has enacted statutes that delegate limited tariff authority to presidents. The decisive issue in this case was whether IEEPA was one of those statutes. Six Justices concluded that it was not.
“IEEPA does not authorize the President to impose tariffs.”

A 6-3 Majority — but Not One Single Legal Theory
The vote was 6-3, and two of Trump's own Supreme Court appointees — Neil Gorsuch and Amy Coney Barrett — joined Chief Justice John Roberts in rejecting the administration's IEEPA theory. Justices Sonia Sotomayor, Elena Kagan and Ketanji Brown Jackson also voted for the same bottom-line result. Justices Clarence Thomas, Samuel Alito and Brett Kavanaugh dissented.
But describing all six Justices as adopting the same constitutional rule would be misleading. Roberts, Gorsuch and Barrett concluded that a claim of such economically and politically consequential authority required clear congressional authorization, applying the Court's major questions doctrine. They stressed that Congress has historically delegated tariff authority expressly and with limits, while no president in IEEPA's nearly half-century history had used it to impose tariffs of this scale.
Kagan, joined by Sotomayor and Jackson, agreed that IEEPA does not authorize tariffs but said the Court did not need the major questions doctrine to get there. In her view, ordinary statutory interpretation was enough. Jackson separately emphasized legislative history as further evidence that Congress did not intend IEEPA to function as a tariff statute.
The dissenters read the law differently. Kavanaugh, joined by Thomas and Alito, argued that the statutory power to "regulate ... importation" historically encompassed duties on imports and therefore covered tariffs. Their disagreement underscores that this was not a policy vote on whether tariffs are wise; it was a dispute over what Congress actually authorized in the text and history of IEEPA.
Why Congress's Tariff Power Matters
The constitutional backdrop is central. Article I, Section 8 empowers Congress to lay and collect taxes, duties and imposts. That allocation matters because tariffs are not merely diplomatic signals; they are taxes collected on imported goods, affecting importers, supply chains, prices and federal revenue.
The Roberts opinion described the government's IEEPA reading as a potentially transformative expansion of presidential power. IEEPA authorizes the president during qualifying emergencies to investigate, block, regulate, nullify, prevent or prohibit certain economic transactions and importation. But the statute never uses the words "tariff" or "duty." For the majority, that omission was decisive when compared with other trade laws that expressly authorize tariffs and include procedures, ceilings or time limits.
The ruling therefore reinforces a separation-of-powers principle without eliminating executive flexibility: presidents can exercise tariff authority Congress has actually delegated, but they cannot assume that every broad emergency-management verb silently contains the power to tax imports.
Trump's Response Was Immediate — and Personal
Trump reacted angrily within hours. At a White House appearance, he called the decision "deeply disappointing," said he was "ashamed" of certain members of the Court, praised Thomas, Alito and Kavanaugh for dissenting, and attacked the Justices who ruled against him. He later singled out the conservative Justices who had joined the majority and framed the ruling as harmful to American leverage in trade negotiations.
That rhetoric is politically significant, but it does not change the legal effect of the judgment. The Supreme Court's decision invalidated the administration's reliance on IEEPA for the challenged tariffs, and the executive branch immediately began operating through other statutes rather than ignoring the ruling.
The Ruling Did Not End Trump's Tariff Agenda
The most important correction to sweeping summaries of the case is that the Court did not strike down every tariff in Trump's trade program. Duties imposed under other laws — including national-security tariffs under Section 232 of the Trade Expansion Act — were outside the IEEPA holding.
On the same day as the ruling, Trump invoked Section 122 of the Trade Act of 1974 to announce a temporary 10% import surcharge, effective February 24. Unlike the IEEPA theory, Section 122 expressly authorizes a temporary surcharge in specified balance-of-payments circumstances and limits it to 150 days unless Congress extends it by law.
By September 2026, the administration had continued building trade measures through other authorities, including Sections 232 and 301 and the rarely used Section 338 of the Tariff Act of 1930. Those statutes come with their own triggering findings, procedures and legal limits. They can still face litigation, but the February ruling does not automatically invalidate them.
In other words, the Court shut one very broad legal door. It did not lock the entire tariff toolbox.
What the Decision Means for Presidential Power
The ruling is likely to remain important well beyond the immediate trade fight because it addresses the relationship between emergency statutes and presidential power. The Roberts-Gorsuch-Barrett opinion rejected the idea that invoking an emergency automatically allows the executive branch to discover extraordinary powers in ambiguous statutory language. Their reasoning said emergencies do not create an exception to the requirement that major delegations come from Congress.
At the same time, the narrower concurring path taken by Kagan, Sotomayor and Jackson matters. Because they did not join the major-questions portion, it would be inaccurate to describe the 6-3 ruling as a single sweeping constitutional doctrine governing every future emergency-power dispute. What unites the six is the statutory conclusion: IEEPA itself does not contain tariff authority.
That distinction makes the precedent both powerful and bounded. Future presidents of either party may still invoke emergency statutes for powers those laws actually grant. They may also impose tariffs where Congress has expressly authorized them. What Learning Resources rejects is the specific claim that IEEPA's authority to regulate importation silently includes an unlimited tariff power.
What the Ruling Does — and Does Not — Prove
The decision supports the broader argument that courts can enforce statutory limits even when a president invokes national emergencies or foreign affairs. It also confirms that Trump's nominees do not automatically vote for his administration: Gorsuch and Barrett joined the judgment against him.
But the ruling should not be stretched into claims it did not make. It did not find Trump's entire economic program unconstitutional. It did not forbid Congress from delegating tariff power. It did not invalidate every tariff then in force. And it did not resolve every downstream issue, including all questions over refunds of revenue collected under the invalidated IEEPA tariffs.
Those limits are essential to a defensible account of the case. The ruling was a substantial defeat for the administration's preferred emergency-tariff mechanism, but it also triggered a rapid legal and policy pivot rather than the end of tariff-based trade policy.
Conclusion
The Supreme Court's 6-3 decision in Learning Resources marked a sharp institutional check on one of Trump's most expansive claims of unilateral economic authority. Six Justices agreed that IEEPA does not authorize presidential tariffs, and two Trump appointees joined the majority. The decision reinforced Congress's central role over duties and taxation while leaving intact tariff powers that Congress has delegated through other laws.

The larger constitutional question raised by the case is therefore not whether presidents should have no power over trade. It is whether the executive branch may transform a general emergency statute into a source of taxation authority that Congress never expressly placed there. On that question, the Court's answer was no — while leaving the political branches to fight over what tariff authority Congress has granted elsewhere and whether those tools should be used.
