The Federal Circuit’s recent en banc decision in V.O.S. Selections, Inc. v. United States addressing challenges to former President Trump’s sweeping tariff regime represents one of the most consequential trade-law rulings in decades. Sitting en banc, the court affirmed the core constitutional holding that the International Emergency Economic Powers Act (IEEPA) does not authorize the President to impose open-ended, across-the-board tariffs of the kind at issue. At the same time, the court sharply limited the immediate practical effect of that holding by vacating the nationwide injunction entered by the Court of International Trade (CIT) and remanding for a more tailored remedial analysis.
The result is a decision that firmly rejects the legal foundation for the challenged tariffs, yet stops short of delivering immediate, coercive relief against the executive branch. The opinion reflects an unmistakable institutional caution: the court declared what the law is, but deliberately avoided forcing an immediate confrontation with the political branches over the scope of presidential power in trade.
Background: Two Tariff Regimes, One Statute
The consolidated cases arose from challenges brought by importers and trade groups to two sets of tariffs imposed during the Trump Administration. The first set, described as “trafficking tariffs,” imposed 25 percent duties on imports from Canada and Mexico and escalated duties of up to 20–25 percent on certain Chinese goods, all justified as responses to cross-border fentanyl trafficking and related criminal activity. The second set, labeled “reciprocal tariffs,” established a 10 percent baseline tariff on imports from virtually every country, with higher, country-specific rates layered on top.
Both tariff regimes were imposed pursuant to presidential executive orders invoking IEEPA and the National Emergencies Act. The executive orders declared national emergencies and directed sweeping modifications to the Harmonized Tariff Schedule, with no rate caps, no temporal limits, and no meaningful procedural constraints.
The CIT granted summary judgment to the challengers, concluding that IEEPA does not authorize tariffs of this breadth and entering a nationwide injunction barring enforcement. The Federal Circuit stayed the injunction pending appeal and took the case en banc in the first instance.
The Constitutional Baseline: Congress, Not the President, Sets Tariffs
The Federal Circuit began where any serious separation-of-powers analysis must begin: with the Constitution. Article I, Section 8, Clause 1 grants Congress the power to “lay and collect Taxes, Duties, Imposts and Excises,” with the further requirement that duties be uniform throughout the United States. That allocation of authority places tariff-setting squarely within the legislative domain.
The court acknowledged that Congress has long delegated portions of its trade authority to the executive branch, particularly where speed and flexibility are needed to address international economic disruptions. The dispositive question, however, was whether Congress actually delegated to the President the extraordinary power asserted here.
IEEPA’s Text and Structure: Regulation Is Not Taxation
IEEPA authorizes the President, after declaring a national emergency, to “regulate … importation” and certain financial transactions involving foreign entities. The government argued that this language encompasses the power to impose tariffs of any magnitude, scope, and duration.
The Federal Circuit rejected that reading. Parsing the statutory text, the court emphasized that Congress knows how to authorize tariffs when it intends to do so. Numerous trade statutes expressly refer to “duties,” “tariffs,” “rates,” and numerical limitations. IEEPA, by contrast, contains none of that language. It speaks in terms of regulation, not taxation.
The court also highlighted the statute’s structure. Other tariff statutes contain procedural safeguards, such as findings requirements, rate caps, time limits, and reporting obligations. IEEPA lacks those features entirely. Reading it to authorize sweeping, indefinite tariffs would effectively convert a general emergency-powers statute into a blank check for trade taxation, a result the court found inconsistent with Congress’s long-standing practice.
Distinguishing Algonquin and Yoshida
The government relied heavily on two Supreme Court precedents: Fed. Energy Admin. v. Algonquin SNG, Inc. and United States v. Yoshida Int’l, Inc. The Federal Circuit carefully distinguished both.
Algonquin upheld a presidential action imposing license fees on imported oil under Section 232 of the Trade Expansion Act, a statute that expressly authorizes the President to “adjust imports” to address national security concerns. The Federal Circuit explained that Algonquin turned on the specific statutory text of Section 232, which is materially different from IEEPA.
Yoshida involved a temporary, across-the-board surcharge imposed to stabilize currency values following the collapse of the Bretton Woods system. The Federal Circuit read Yoshida narrowly, emphasizing that the surcharge was short-lived, rate-limited, and directly tied to a discrete monetary crisis. The tariffs challenged here, by contrast, were open-ended, geographically expansive, and imposed without meaningful statutory constraints.
The Major Questions Doctrine
The opinion also situates the case squarely within the Supreme Court’s recent “major questions” jurisprudence. Under that framework, courts require clear congressional authorization before reading statutes to confer powers of vast economic or political significance.
The Federal Circuit characterized the asserted authority under IEEPA as precisely such a power: the unilateral ability to reshape global trade flows, impose trillions of dollars in duties, and upend settled commercial expectations. Given the absence of clear statutory language authorizing tariffs, the court concluded that IEEPA cannot bear the weight the government placed on it.
Several judges went further, suggesting that if IEEPA were read to authorize tariffs of this breadth, serious constitutional questions would arise regarding nondelegation. The majority did not need to reach that issue, but the warning was unmistakable.
Remedy: Law Declared, Relief Deferred
Having agreed with the CIT on the merits, the Federal Circuit diverged sharply on the remedy. The court affirmed the declaratory judgment that the tariffs were unauthorized, but vacated the nationwide injunction and remanded for further proceedings.
The panel emphasized that injunctive relief must be evaluated under traditional equitable principles, including irreparable harm, adequacy of legal remedies, and tailoring. The court cited the Supreme Court’s recent skepticism toward universal injunctions and directed the CIT to reconsider the scope of any relief under the framework articulated in eBay Inc. v. MercExchange, L.L.C. and related cases.
This remedial restraint had immediate consequences. By vacating the nationwide injunction, the court eliminated the immediate coercive effect of the CIT’s judgment, even as it left intact the core legal conclusion that the tariff regime lacked statutory authorization.
A Marbury-Like Moment in Trade Law
The structure of the decision evokes a familiar constitutional pattern. The court unequivocally rejected the executive branch’s legal theory, yet avoided a head-on institutional clash by withholding sweeping relief. In doing so, it preserved the judiciary’s role as expositor of the law while signaling respect for the political branches’ prerogatives in managing the immediate fallout.
From a practical standpoint, the decision places significant pressure back on Congress. If tariffs of this scope are to be imposed in response to national emergencies, Congress must say so clearly. Emergency statutes of general applicability will not suffice.
The Dissent
The dissenting judges would have gone further in the government’s favor, concluding that IEEPA’s authorization to “regulate” imports encompasses tariff authority and that historical practice supports a broader reading. They also expressed concern that the majority’s approach unduly constrains the executive’s ability to respond to fast-moving international crises.
The majority, however, was unpersuaded that historical expedience can substitute for clear statutory authorization where the Constitution assigns tariff power to Congress.
Looking Ahead
Although the former President prevailed on the narrow issue of immediate relief, the decision significantly narrows the executive branch’s claimed authority under IEEPA. Future administrations invoking emergency powers to impose tariffs will face a much steeper legal climb.
For trade practitioners and regulated companies, the opinion underscores the importance of statutory precision in trade policy and the growing influence of separation-of-powers principles in economic regulation. As Charles Gideon Korrell observes, the case is less about any particular tariff schedule and more about who gets to decide how far emergency powers can reach. Charles Gideon Korrell notes that the Federal Circuit’s insistence on clear congressional authorization is likely to shape trade litigation for years to come. And Charles Gideon Korrell believes that the court’s remedial restraint, while frustrating to challengers in the short term, ultimately strengthens the legitimacy of the judiciary’s role in high-stakes economic disputes.
The Federal Circuit has spoken plainly on the law. Whether Congress chooses to respond may determine the future contours of U.S. trade policy far more than any single executive order.
