ANALYSIS : The Supreme Court Strikes Down Trump's IEEPA Tariffs — and the West Holds Its Breath

Introduction: The Legal Earthquake That Redraws Global Trade

A 6-3 Verdict That Shakes the White House

On February 20, 2026, the United States Supreme Court issued one of the most consequential rulings of the decade in trade policy. In Learning Resources Inc. v. Trump, six justices out of nine ruled without ambiguity: President Donald Trump was not authorized to impose sweeping tariffs under the International Emergency Economic Powers Act (IEEPA), a 1977 law designed to manage economic crises, not to circumvent Congress on matters of taxation. The vote, 6 to 3, landed like a thunderclap in the corridors of the American executive branch.

What the majority — including conservative Chief Justice John Roberts — established is constitutionally unambiguous: the delegation to the executive of authority to "regulate importation" in the IEEPA does not include the power to levy fiscally significant tariffs. That power belongs to Congress, under the Constitution's taxing clause. Imposing tariffs worldwide on nearly all American trade partners is fiscal policymaking — and fiscal policy at that scale requires explicit legislative authorization.

A Succession of Judicial Rulings Encircling the Executive

The Supreme Court's decision did not occur in a legal vacuum. It was preceded by similar rulings from the Court of International Trade (CIT), a specialized body that had already fired several warning shots against the Trump administration's tariffs. On May 7, 2026, that same court delivered another blow, striking down Trump's recourse to Section 122 of the Trade Act of 1974 — the replacement measure he had put in place within hours of the Supreme Court ruling — at least for the three importers who were plaintiffs in that case.

This coordinated judicial movement, driven by small businesses and American states, illustrates the institutional resistance that the democratic West can still mobilize against executive overreach. The courts are holding. The checks and balances are working. Imperfectly, laboriously — but they are working.

The IEEPA: An Emergency Law Repurposed for Unprecedented Fiscal Ends

What the IEEPA Permitted — and What It Did Not

The International Emergency Economic Powers Act was enacted in 1977 to give the American president extraordinary powers in the event of a national, foreign, or serious threat to the security of the United States. Its provisions allow asset freezing, sanctioning of foreign entities, and blocking of transactions. No president before Trump had ever attempted to use this tool to impose generalized tariffs on all of the country's trading partners. It was a first — and an audacious one.

The Trump administration justified this use of the IEEPA by declaring "national emergencies" tied to American trade deficits, the fentanyl crisis flowing from China and Mexico, and other geopolitical concerns. The argument was clever: if anything can constitute a national emergency, the executive holds an unlimited power to tax by decree. The Supreme Court rejected this logic in the clearest possible terms. According to the majority, if Congress had intended to delegate such a fundamental power, it would have done so explicitly.

The "Liberation Day" Tariffs and Their Devastating Effect on Allies

The so-called "Liberation Day" tariffs Trump imposed in spring 2025 put the entire commercial world under strain. They triggered a chain reaction: China responded with counter-tariffs and restrictions on rare earths, politically symbolic goods like American soybeans were boycotted, and several Western allies — Europe, Japan, South Korea — negotiated costly concessions to obtain reduced rates. The average effective tariff rate on American imports climbed to nearly 17%, the highest level since the early 1930s.

According to data from the Federal Reserve Bank of New York, nearly 90% of the cost of these tariffs was absorbed by American businesses and consumers — not by the targeted exporting countries. The Tax Foundation estimated that the tariffs had added roughly $1,000 to annual household costs in 2025 and up to $1,300 in 2026. This is not trade policy: it is a regressive tax in disguise.

The Lightning Substitution: Section 122 Enters the Scene

A Replacement Signed the Day of the Supreme Court Ruling

Where many would have retreated, Trump maneuvered. Within hours of the Supreme Court ruling on February 20, 2026, the president signed Proclamation 11012, based on Section 122 of the Trade Act of 1974. This provision authorizes the president to impose a temporary import surcharge of up to 15% for a maximum of 150 days, when fundamental balance-of-payments problems require it. The new tariffs — set initially at 10%, then raised to 15% — took effect on February 24, 2026 and are set to expire on July 24, 2026, unless Congress votes to extend them.

The speed of this substitution did not surprise close observers. According to Brookings analysis, the administration had prepared a fallback before the Court delivered its verdict. This immediate pivot to Section 122 demonstrates that Trump and his team had incorporated the possibility of a judicial defeat and had developed a layered trade strategy built on multiple distinct legal authorities: Section 122, Section 232 (national security), and Section 301 (unfair trade practices).

The Constitutional Limits of Section 122

Section 122 is not a magic solution. It comes with its own legal constraints. Its duration is strictly limited to 150 days — a protection inscribed by Congress precisely to prevent this mechanism from becoming a tool of permanent fiscal policy. Moreover, tariffs imposed under Section 122 must respond to balance-of-payments deficits measured according to specific metrics that Congress had in mind in 1974: liquidity deficits, official settlements balances, and basic balance. The CIT ruled on May 7, 2026, that the metrics invoked in Proclamation 11012 — trade deficits, current account deficits, net investment position — were not the correct statutory metrics.

The administration immediately appealed to the U.S. Court of Appeals for the Federal Circuit, which granted a temporary stay on May 12. The legal battle is far from over. But the calendar is unforgiving: on July 24, 2026, the Section 122 tariffs expire regardless — unless Congress votes to extend them, which would require Republican legislators to take a public stand just before the 2026 midterm elections.

The Refund Abyss: $130 to $175 Billion at Stake

The Staggering Numbers of a Government Debt to Its Own Businesses

The Supreme Court invalidated the IEEPA tariffs, but said nothing about refunds. That silence opened a dispute of unprecedented scale. Estimates of the total IEEPA tariffs collected and now potentially refundable range from $130 to $175 billion — depending on the legal and governmental source. Some reports put the consolidated figure at $166 billion, a large portion of which has already entered the CAPE refund system.

CAPE — Consolidated Administration and Processing of Entries — is the portal that U.S. Customs and Border Protection (CBP) developed and launched on April 20, 2026, to process refund claims. In Phase 1, CAPE covers entries not yet finally liquidated or liquidated within the past 80 days. By May 26, CBP had received approximately 157,400 CAPE declarations, accepted approximately $85 billion in claims, and already processed roughly $20.6 billion. By June 9, the amount approved and transmitted to the Treasury had exceeded $23 billion, with a projection of reaching $40 billion before month's end.

Small Businesses Caught in a Kafkaesque Bureaucratic System

But behind the big numbers lies a brutal reality for thousands of small importers. The CAPE Phase 1 system covers only entries liquidated within the past 80 days — approximately 63% of the total IEEPA duties collected. The so-called "finally liquidated" entries, those with more than 80 days of liquidation, represent about 6.9% of the total, or roughly $11.4 billion. And the administration contests that refunds are automatically owed to all importers.

Judge Richard Eaton of the CIT, overseeing the execution of the universal refund order, summoned CBP Commissioner Rodney Scott in person to account for progress on June 9. He said plainly that the administration's appeal against the universal refund order was a clear signal that the government did not want to repay the full amount owed. The Cato Institute, in an analysis published June 1, put it most simply: the government collected billions of dollars through an illegal tariff regime, and using procedural obstacles to deny refunds should not be tolerated.

The Impact on American Businesses: An Asymmetric Burden

SMEs and Black-Owned Businesses on the Front Lines

Data published by the Center on Budget and Policy Priorities (CBPP) paints an unambiguous picture of the tariffs' impact on American businesses. Approximately 90% of the cost of the IEEPA tariffs was borne by American businesses and consumers. In a study cited by the Spokesman-Recorder, 52% of Black-owned businesses reported a drop in sales due to the tariffs. These businesses are particularly vulnerable: thinner profit margins, limited access to capital, concentration in import-dependent sectors.

Tony Barnes, co-owner of restaurant Oohh's & Aahh's, summarized the situation in one line: "At the end of the day, we're all taking the backlash of their decisions." The manager of JC Lofton Tailors, known to clients as Shoemaker, was more direct: "The prices have changed. They go up. So you have to raise your prices on customers, and you don't want to lose them." These are human voices behind abstract statistics. These people are not making trade policy — they are trying to survive.

The Main Street Alliance Survey: SMEs Under Existential Pressure

The Main Street Alliance conducted a survey of American SMEs whose results are striking: 81.5% of respondents had raised or were considering raising prices; 41.7% had delayed or were considering delaying expansion; and nearly a third anticipated layoffs. According to expert Eric Morrissette of the Joint Center for Political and Economic Studies, the decision to impose and rapidly escalate tariffs injected uncertainty and unpredictability into markets that serves neither the economy nor its participants.

Phase 3 of CAPE, expected in late July 2026, will be accessible — per the administration's current position — only to importers who filed individual claims before the CIT. For thousands of small importers who lack the resources to engage in judicial proceedings, that door will remain closed. Senator Edward Markey and Senator Ron Wyden sent a letter to the CBP commissioner on June 10 demanding full, immediate refunds, declaring that the administration had "slow-walked the implementation of the refund process from the beginning."

Institutional Resistance: When the Courts Hold Firm

The Pivotal Role of the Court of International Trade

The Court of International Trade (CIT) played a central role in this saga. It was the CIT that, on March 4, 2026, in Atmus Filtration v. U.S., ordered CBP to refund the illegal IEEPA tariffs. It was the CIT that, on May 7, 2026, found that the Section 122 tariffs also exceeded presidential authority — even if, in that case, the ruling's scope was limited to the three plaintiff importers. And it is before the CIT that Judge Eaton continues monitoring the execution of refund orders, refusing to let the administration trample the court's directives.

On June 9, during a tense hearing, Judge Eaton stated that the government's appeal clearly indicated the administration did not want to refund the full amounts owed. He held the line. In a functioning democracy, that is what is expected of a judge. The Brookings analysis highlights a crucial point: Trump, despite his public attacks on the ruling, chose to comply with the verdict and pivot to other legal authorities. In doing so, he avoided what some had feared: an open constitutional crisis.

The Roberts Precedent: A Signal for the Future of the Rule of Law

Chief Justice John Roberts authored a majority opinion that was — ironically — supported by three of his conservative colleagues, including two appointed by Trump himself. That fact alone sends a strong signal. The major questions doctrine did not produce unanimity among conservatives: Justice Kavanaugh found it did not apply in matters of emergency or foreign affairs, while Justice Thomas dissented and Justice Barrett questioned her colleagues' reasoning. This internal divide among conservatives undermines the notion that this Court acts in purely partisan fashion.

William A. Galston of Brookings summarizes the democratic stakes well: the fact that Trump accepted the decision as binding and immediately sought legal alternatives suggests his administration respects, at bottom, judicial supremacy — which was not guaranteed. That is a victory for the Western rule of law. Imperfect, conditional, fragile — but real.

Congress Faces Its Responsibilities: The Ball in Republicans' Court

Section 122 Forces Legislators to Vote Before the Midterms

One of the most significant effects of the IEEPA saga is political, and it looms on the horizon of July 24, 2026: the expiration date of the Section 122 tariffs. If Congress does not vote to extend them before that date, those tariffs automatically lapse. This mechanism places Republican legislators in a politically delicate position: publicly back unpopular tariffs in a midterm electoral context, or let expire one of Trump's last large-scale tariff instruments.

According to polls cited by Brookings, more than 60% of Americans disapproved of the tariffs — including nearly a quarter of Republicans and three-quarters of independents. House Speaker Mike Johnson had managed to suppress most tariff votes throughout 2025. But circumstances have changed. Democrats, including Senators Markey and Wyden, are actively pushing for votes on refunds and limits to presidential tariff powers.

The Tariff Refund Act: A Bipartisan Signal

In the Senate, the Tariff Refund Act of 2026 — which would require refunds within 180 days with interest, explicitly prioritizing small businesses — was introduced. This bill is a direct acknowledgment that the CAPE system was not designed with small importers in mind. Only about 6% of eligible importers had enrolled in the ACH portal at launch. The majority of small businesses did not even know they were eligible for refunds — or that deadlines for filing claims were already passing.

The RELIEF Act (Restoring Economic Lifelines for Independent Enterprises and Family Businesses), introduced in the House as H.R. 7736, goes further: it would require automatic refunds within 90 days to small businesses that paid IEEPA tariffs. These legislative efforts converge on a single finding: the current refund process is insufficient, opaque, and discriminatory toward smaller economic actors.

China in the Wings: The Real Winner of This Legal Battle?

Beijing Watches, Accumulates, and Capitalizes on American Confusion

While Washington tore itself apart in legal battles over the legality of its own tariffs, China observed, calculated, and consolidated its positions. The counter-tariffs imposed by Beijing in response to "Liberation Day" had targeted with precision politically sensitive goods for American rural states — soybeans, agricultural products — while limiting its own restrictions on exports of rare earths, on which the United States and its allies remain heavily dependent. China transformed a trade confrontation into a strategic display of power.

According to Kyle Chan of Brookings, the Supreme Court's ruling actually strengthens the American position vis-à-vis China in the medium term, by forcing recourse to better-targeted and legally grounded tariff tools — Sections 301 and 232 in particular — rather than mass IEEPA tariffs that hit allies and adversaries indiscriminately. Tariffs on Chinese steel, automotive parts, and technology products rest on these authorities, not IEEPA. They hold legally.

Chinese Commitments on Fentanyl: Wind and Facade

One of the central arguments of the Trump administration for justifying IEEPA tariffs targeting China was the fentanyl crisis — chemical precursors transiting through China to Mexican cartels before flooding the American market. But expert Vanda Felbab-Brown of Brookings highlights a stinging reality: the commitments made by China in October 2025 on fentanyl control were essentially reaffirmations of promises made to the Biden administration in late 2024. The gaps in chemical precursor controls remain wide open.

China used the IEEPA tariffs as a pretext to position itself as the victim of aggressive and illegal trade policy — which the Supreme Court ultimately confirmed. Beijing barely had to try: Washington did the work for it. The lesson for the West is blunt: striking blindly with untargeted tariffs means giving adversaries a victimhood narrative that their populations, potential allies, and multilateral organizations are ready to embrace.

The Major Questions Doctrine and the Limits of Executive Power

A Constitution That Reasserts Itself

The Learning Resources ruling fits within a broader constitutional dynamic. Over recent years, the Supreme Court has progressively reaffirmed the limits of legislative delegation to the executive, notably through the major questions doctrine — under which Congress must speak clearly when it intends to delegate powers of exceptional economic or political scope. West Virginia v. EPA established this principle in the environmental domain. Learning Resources confirms it in the fiscal and trade domain.

The Roberts majority was careful to note that it did not rely solely on the major questions doctrine, but on "normal tools of statutory interpretation." That clarification matters: it broadens the ruling's reach beyond theoretical debates on non-delegation. It simply says: read the text. If the word "tariffs" is not there, the president cannot impose them. The simplicity of this reasoning is its strength.

What the Ruling Means for Other Presidential Prerogatives

Scott R. Anderson of Brookings raised a troubling question: if Trump cannot levy tariffs through IEEPA because it encroaches on Congress's taxing power, how can he require Nvidia to cede 25% of its sales to the American state in exchange for export licenses? Or compel Ukraine to share mineral revenues in exchange for military support? These questions are not rhetorical — they could lead to major new judicial disputes.

Ben Harris of Brookings also flagged an unexpected risk: the Sanctioning Russia Act, a bipartisan bill awaiting a Senate vote, which could quietly grant the White House the power to impose 500% tariffs on any country importing Russian oil — an extraordinary delegation of tariff power that would pass almost unnoticed in the current context.

The West's Allies: From Mistrust to Calculated Prudence

The European Union: Relief Tinged with Vigilance

The European Union welcomed the Supreme Court ruling with relief tinged with anxiety. On one hand, the end of the massive IEEPA tariffs momentarily lifts pressure on European exporters. On the other, the Section 122 tariffs at 15% add to duties already in place, and potential Section 301 investigations — targeting European agricultural subsidies, digital taxes, and VAT exemptions — represent an underlying threat. The European Parliament suspended examination of tariff-reduction commitments negotiated by the Commission the previous summer.

Expert Daniel S. Hamilton of Brookings summarizes the European position: transatlantic partners want Washington to clarify its intentions and avoid a total transatlantic security crisis. The West's allies are not seeking confrontation with the United States — they are seeking predictability. Which Trump, by design unpredictable, has precisely refused to provide. Predictability is not weakness: it is the foundation of any durable alliance.

Asia-Pacific: Deals Already Struck Remain in Place

In the Asia-Pacific, the situation is more nuanced. According to analyst Mireya Solís of Brookings, regional countries — Japan, South Korea, Taiwan, Malaysia, Cambodia — will not undo already-negotiated trade agreements, even if those agreements involved costly concessions such as massive investment commitments in the United States or alignment with American economic security policies. These countries paid a high political price for those deals. They will not discard them at the first opportunity.

South Korea and Japan find themselves at approximately 15% under Section 122 — roughly what they had already negotiated. India and Vietnam remain in more uncertain situations. And China, whose overall rates mechanically decline as the highest IEEPA tariffs are removed, paradoxically emerges from this episode with slightly less American tariff pressure — precisely what Trump had sworn to avoid.

Sections 232 and 301: The Weapons Still Standing in Trump's Arsenal

Section 232: National Security as a Tariff Foundation

With IEEPA sidelined and Section 122 time-limited, the administration turns to two other trade authorities with a more solid legal foundation: Section 232 of the Trade Expansion Act of 1962 and Section 301 of the Trade Act of 1974. Section 232 authorizes the president to impose tariffs in the name of national security, following a formal Commerce Department investigation. It was already used to justify steel and aluminum tariffs, and the administration is considering extending it to sectors such as copper, agricultural chemicals, electrical transformers, and military optics.

According to analyst Michael O'Hanlon, it is legitimate for the United States to be more interventionist in economic industrial policy. But he argues for a targeted approach: semiconductors, rare earths, magnets, pharmaceuticals — sectors where America has a critical and documented dependency. Striking broadly with universal tariffs dilutes strategic impact and weakens the coalition of allies the United States needs to enlist in its competition with China.

Section 301: Potentially the Most Durable Tool

Section 301 may be the most formidable weapon remaining in the arsenal. It authorizes targeted tariffs against countries engaged in unjustifiable, unreasonable, or discriminatory trade practices, following a public USTR investigation. These tariffs have no time limit — unlike Section 122. The administration has signaled its intent to launch Section 301 investigations targeting industrial overcapacity, digital taxes on American companies, drug pricing, and ocean pollution — targets that include not only China, but also Europe and Asian economies.

According to Skadden's analysis, Section 301 tariffs to come could approach the IEEPA tariffs in scale and scope — but with an incomparably stronger legal foundation. In other words, the trade war does not end with IEEPA. It simply changes its legal underpinning. And that should concern allies as much as adversaries.

Economic Projections: A Minefield Between Yale, CBO, and Reality

An Effective Average Tariff Rate Still Historically Elevated

Despite the invalidation of IEEPA tariffs, the average effective American tariff rate remains at levels unseen since the pre-GATT era. The Yale Budget Lab calculated that eliminating the IEEPA tariffs brings the average effective rate to approximately 9.1% — the highest level since 1946, outside of 2025. With Section 122 tariffs at 10%, that rate rises to 13.7%. The difference from the IEEPA regime (16%) is real but insufficient to constitute meaningful relief for most importing businesses.

The Congressional Budget Office (CBO) had projected that tariffs in their entirety would generate nearly $3 trillion over ten years if maintained at IEEPA levels. The loss of IEEPA tariffs reduces that projection to approximately $2 trillion if the Section 122 regime is extended. According to experts William Gale and Elena Patel of Brookings, this fiscal policy disguised as trade policy is one of the largest and most volatile tax increases in modern American history — with documented regressive effects on lower-income households.

The Federal Budget as Hostage to Tariff Policy

Aaron Klein of Brookings identified a fundamental fiscal tension: on one side, the Trump administration is pushing for massive tax cuts for the wealthy; on the other, it is offsetting part of the revenue shortfall with tariffs that function as regressive taxes on consumers and SMEs. Eliminating tariffs without cutting spending or raising other taxes will mechanically create historic peacetime deficits. And if imports decline under the weight of tariffs, tariff revenues collapse too — making the promise of funding government with tariffs arithmetically impossible.

Tariffs cannot simultaneously eliminate imports, fund the government, and serve as a geopolitical adjustment lever. That is arithmetically impossible. Trump tried to make them serve all three purposes at once. The Supreme Court, for its part, stated a simpler truth: tariffs at this scale are fiscal policy. And fiscal policy begins in Congress.

Trump: Necessary Firmness or Unacceptable Institutional Excess?

Right on Substance, Wrong on Method

It would be too easy to conclude Trump was entirely wrong. He was not. His conviction that the United States had allowed unsustainable trade imbalances to develop, that China was deliberately playing with rigged rules, that NATO allies were free-riding on American security — these observations are not wrong. They are even partially correct, and Obama, then Biden, had begun to address them. Trump's merit was putting them brutally on the table.

But the IEEPA method reveals an authoritarian reflex the West cannot afford. Circumventing Congress by decree to levy hundreds of billions in taxes on its own citizens, hitting allies and adversaries indiscriminately, then refusing to refund amounts illegally collected — this is not firmness. It is institutional arbitrariness. And institutional arbitrariness is precisely what China, Russia, and Iran feed on to discredit the Western democratic model.

The Legitimacy of Firmness vs. the Drift of Methods

This column's editorial position is not to defend Trump at all costs, nor to condemn him on principle. It is to distinguish. Firmness toward China: legitimate. Rebalancing trade relations with sometimes opportunistic allies: necessary. Strategic reindustrialization of critical sectors: urgent. But the path chosen — IEEPA tariffs without legal mandate, without allied consensus, without precise targeting — produced the worst of both worlds: real economic damage for Americans, a China that emerges nearly unscathed, and allies who were frightened rather than rallied.

The West needs a coherent commercial strategy against its systemic adversaries. That strategy cannot rest on emergency decrees that collapse in court six months after announcement. It must be built on solid legal foundations, with Congress, with allies. Otherwise, the next time the West wants to present a united front against China, it will no longer have the institutional means to do so.

Conclusion: July 24 — Deadline for a West at a Crossroads

What July 24, 2026 Really Means

July 24, 2026 is not merely a technical expiration date for Section 122 tariffs. It is a test of institutional maturity for the West. If the American Congress votes — or does not — to extend these tariffs before that date, it will say something important about its capacity to exercise its constitutional prerogatives in fiscal and trade policy. If new Section 301 investigations are launched in the interim, they will outline the real architecture of American trade policy for the coming years. And if refunds of IEEPA tariffs — $166 billion legally owed to American businesses — continue to be obstructed by appeals and bureaucratic delays, the American rule of law will emerge permanently tarnished.

China, Russia, and Iran are watching. They are measuring. They are waiting. Every time the West contradicts itself, trips over its own rules, or treats allies with contempt, they take note. The world does not need a perfect West. It needs a credible West. And credibility is built by respecting the law — beginning with one's own.

The Lasting Legacy of the Learning Resources Ruling

Learning Resources Inc. v. Trump will enter American constitutional law textbooks. Not because it ends Trump's trade policy — it does not. Not because it resolves the economic competition with China — it does not do that either. But because it reaffirms, at the right moment, a founding truth of liberal democracy: the power to tax belongs to elected representatives, not to a single man who declares an emergency. That is a line six justices — including two appointed by Trump — refused to let be crossed. And that line is what separates a democracy from an autocracy.

The West will face other crises. Other presidents, other governments will seek to stretch their powers. The question is not whether those moments will come — they will. The question is whether institutions will hold. This time, they held. That is enough reason not to despair.
