Constitutional victories are supposed to constrain government power. Learning Resources, Inc. v. Trump, 607 U.S. (2026), did something rarer: it constrained one mechanism of government power while leaving the underlying capacity almost entirely intact. The Supreme Court held 6–3 on February 20, 2026, that the International Emergency Economic Powers Act (“IEEPA”) does not authorize tariffs. Within hours, the administration invoked Section 122 of the Trade Act of 1974 to impose a replacement surcharge of up to 15% on virtually all imports. Treasury Secretary Bessent stated publicly that these combined authorities “will result in virtually unchanged tariff revenue in 2026.” The pattern might be called statutory migration: executive tariff authority did not disappear after Learning Resources—it relocated.
The case originated in early 2025, when the administration invoked IEEPA—a 1977 statute granting the President broad emergency economic powers—to levy tariffs on Canadian, Mexican, and Chinese goods over fentanyl trafficking. The “Liberation Day” tariffs followed in April, extending duties to nearly every trading partner based on trade deficit calculations. Small businesses challenged the tariffs simultaneously in two courts. The Court of International Trade granted summary judgment striking them down in May 2025; the Federal Circuit affirmed in August. The Tax Foundation estimated the tariffs added approximately $1,000 in taxes per American household in 2025. By the time oral arguments took place on November 5, the Penn Wharton Budget Model projected that IEEPA collections had generated roughly $175 billion in revenue.
Chief Justice Roberts’s opinion turned on statutory interpretation. IEEPA authorizes the President to “regulate … importation or exportation” during a national emergency. The government argued this language must encompass the power to tax imports. Roberts rejected the reading: “Those words cannot bear such weight.” The statute enumerates nine presidential powers, and tariffs appear nowhere in that catalog. The Court held that tariff power is “very clearly a branch of the taxing power,” one that Congress never delegated through IEEPA. Roberts also observed that no president had interpreted the statute this way in its fifty-year history. In a section joined only by Gorsuch and Barrett, Roberts applied the major questions doctrine, arguing that an assertion of authority this sweeping required clear congressional authorization. That section constitutes a three-justice plurality rather than binding precedent. Kagan, writing with Sotomayor and Jackson, concluded that ordinary statutory interpretation resolved the case without reaching the doctrine at all.
The characterization of tariffs as taxation—not mere trade regulation—is the doctrinal development most likely to outlast the case itself. Roberts grounded this holding in Gibbons v. Ogden and the constitutional structure: the taxing power belongs to Congress, and any delegation of that power requires explicit statutory authorization. If tariffs are a species of the taxing power, then every existing delegation of tariff authority rests on a legislative choice to share that power with the executive—a choice that must be expressed clearly, not implied from broad language. The Court did not examine whether Section 301, Section 232, or Section 122 delegations survive scrutiny under this framework, but the analytical groundwork is laid. Future litigants challenging tariffs under those statutes can now argue that the Court has already classified the power at issue as constitutionally foundational, requiring correspondingly clear authorization. The three-justice plurality’s invocation of the major questions doctrine, while not binding, amplifies this signal: where executive authority touches revenue-raising of this magnitude, courts may demand more than statutory ambiguity permits. Kavanaugh, dissenting with Thomas and Alito, warned that the President could simply reach equivalent tariff rates through other statutes. The majority dismissed the concern as speculation; the executive order signed hours later proved it was not.
Statutory migration explains why the ruling changed trade law without meaningfully changing trade policy. Congress has delegated tariff authority to the executive through a patchwork of statutes—Section 301, Section 232, Section 122—each carrying procedural constraints IEEPA lacked: rate caps, investigation requirements, time limits. The Court eliminated the broadest, fastest, and least constrained vehicle. But the remaining delegations, taken together, still leave the executive branch enormous room to operate. The administration’s same-day pivot to Section 122 demonstrated that the limiting principle is not whether the executive can impose tariffs, but how quickly and at what rate.
The replacement tariff, however, carries vulnerabilities the IEEPA regime did not. Section 122 permits temporary surcharges up to 15% only when “large and serious” balance-of-payments deficits exist, and they expire after 150 days without congressional extension. Policy analysts have observed that no administration invoked this statute during the 1997 Asian financial crisis or the 2008 recession—raising the question of whether today’s trade deficits qualify as the kind of emergency Congress envisioned when it enacted the provision. Twenty-four states have already filed suit challenging the Section 122 tariffs, arguing the statutory predicate conditions are not met. Meanwhile, the administration launched Section 301 and Section 232 investigations, which permit product-specific tariffs but require agency proceedings and formal findings. These investigations take months. The 150-day Section 122 clock, which runs through approximately July 24, 2026, is unlikely to accommodate that timeline.
The refund litigation adds a further dimension of uncertainty. Penn Wharton projects up to $175 billion in potential claims. Nearly 2,000 importers filed suits before the ruling was even issued, and the Court of International Trade has since ordered that all importers of record are entitled to refunds. Yet the mechanics remain contested. Importers face uncertainty regarding whether U.S.
Customs and Border Protection (“CBP”) will process claims cooperatively or resist them. Holland & Knight advised clients to preserve all entry records and file protests immediately. The scale of potential government liability ensures that the refund process will itself become a site of sustained legal conflict.
Learning Resources, Inc. v. Trump thus exposes a structural feature of American trade law that neither the Court nor the Constitution currently addresses: the executive can lose a landmark separation-of-powers case and still maintain substantially the same tariff regime by migrating across statutes. The ruling matters—IEEPA was the broadest and fastest authority available, and its elimination forces the executive into channels with real procedural constraints and shorter time horizons. But the decision also reveals the limits of judicial review as a check on trade policy when Congress has scattered tariff authority across half a dozen statutes, each with its own trigger, scope, and expiration. Until Congress either reclaims tariff authority directly or courts begin scrutinizing the remaining delegations under the tariff-as-taxation framework Roberts articulated, statutory migration will ensure that each legal victory constrains a vehicle without constraining the destination.
