Fourth Circuit: NCAA Five-Year/JUCO Eligibility Rules Are Commercial Under the Sherman Act, but Mandatory Preliminary Injunctions Require Full Rule-of-Reason and a Proven Market

Introduction

In Jimmori Robinson; Jeffrey Weimer; Tye Edwards; Justin Harrington v. National Collegiate Athletic Association, four college football players (the “Players”) challenged the NCAA’s “JUCO Rule,” i.e., the NCAA’s practice of counting junior college (JUCO) enrollment and competition toward the NCAA’s eligibility “clock” under the Five-Year Rule. The challenged framework rendered the Players ineligible to play NCAA Division I football for the 2025–26 season at West Virginia University (WVU). After the NCAA denied individual waivers, the Players sued under §§ 1–2 of the Sherman Act and state law, and sought emergency injunctive relief.

The district court issued a mandatory preliminary injunction allowing the Players to compete during the 2025–26 season and also enjoined enforcement of the NCAA’s “Restitution Rule” (penalties for competing under an injunction later vacated). The NCAA appealed. Because the season ended before argument, the Fourth Circuit first addressed mootness, then the correctness of the preliminary injunction.

Summary of the Opinion

  • Not moot: The appeal fell within the “capable of repetition, yet evading review” exception because a football season is too short to litigate fully and there was a demonstrated probability that at least one Player (Tye Edwards) would again seek relief for the next season.
  • Sherman Act applies (threshold): The court held the challenged eligibility rules are not categorically noncommercial and are subject to Sherman Act scrutiny because they restrain participation in a labor market.
  • Preliminary injunction vacated: The district court abused its discretion on the “likelihood of success” Winter factor by (a) apparently applying “quick-look”/“twinkling of an eye” reasoning where full rule-of-reason was required and (b) failing to properly define and support a relevant market with factual findings and record evidence.
  • Remand: The case returns for further proceedings on a fuller record.
  • Restitution Rule injunction remains: Because the NCAA did not challenge that portion on appeal, the issue was waived and the injunction stayed in place.

Analysis

1. Precedents Cited

A. Mootness and “Capable of Repetition, Yet Evading Review”

The court anchored mootness in Article III’s “case-or-controversy” requirement, quoting the classic formulation from Powell v. McCormack and emphasizing, via Lewis v. Cont'l Bank Corp., that a live controversy must persist through appeal. It reiterated that mootness may be raised sua sponte under United States v. Springer (citing North Carolina v. Rice).

To reject mootness, the court applied the “capable of repetition, yet evading review” framework as stated in Kingdomware Techs., Inc. v. United States. The “effectual relief” standard was drawn from Leaders of a Beautiful Struggle v. Balt. Police Dep't (quoting Chafin v. Chafin), with the “however small” interest principle from Chafin v. Chafin (quoting Knox v. Serv. Emps. Int'l Union, Loc. 1000).

On duration, the court relied on FCC v. Consumers' Rsch., S. Pac. Terminal Co. v. Interstate Com. Comm'n, and Kingdomware Techs., Inc. v. United States to show that short-lived actions commonly evade complete review. On recurrence, it invoked Murphy v. Hunt to distinguish a “demonstrated probability” from a mere theoretical possibility, and then used the Fourth Circuit’s seasonal-industry analogies—Kramer v. Mosbacher and Feller v. Brock—to treat annual football seasons like annual fishing and harvest disputes. The court contrasted Senseny S. Corp. v. Dep't of Lab. (where annual repetition was not shown) and reinforced standing/ongoing exposure via Dunn v. Blumstein.

B. Preliminary Injunction Standards (Including Mandatory Injunctions)

The decision applies the Supreme Court’s modern preliminary injunction framework: Winter v. Nat. Res. Def. Council, Inc. (four factors) and Munaf v. Geren (injunction as extraordinary remedy). The Fourth Circuit’s “exacting standard” and abuse-of-discretion review came from 2311 Racing LLC v. Nat'l Ass'n for Stock Car Auto Racing, LLC (NASCAR), with the standard for reviewing facts and law from Frazier v. Prince George's County. The opinion also underscored that all Winter factors are required under Henderson for NLRB v. Bluefield Hosp. Co..

Because the district court’s order compelled eligibility determinations (altering the status quo), it was a mandatory injunction. The court treated such relief as disfavored and subject to more searching review under In re Microsoft Corp. Antitrust Litig. and reiterated in NASCAR.

C. Antitrust Applicability to NCAA Eligibility Rules (Commercial vs. Noncommercial)

The NCAA’s threshold argument relied on the Sherman Act’s focus on “business and commercial transactions,” as framed in Apex Hosiery Co. v. Leader, and the Fourth Circuit’s commercial-transaction inquiry from Va. Vermiculite, Ltd. v. W.R. Grace & Co. (transaction-specific, not entity-specific).

The court read Supreme Court NCAA cases as rejecting categorical immunity. It drew necessary-cooperation principles from NCAA v. Bd. of Regents of Univ. of Okla. and emphasized that NCAA v. Alston does not exempt NCAA restraints merely because they intersect “higher education, sports, and money.” It also relied on labor-market antitrust analogies in Anderson v. Shipowners' Ass'n of Pac. Coast and Radovich v. Nat'l Football League (NFL) to conclude eligibility rules that limit who can supply athletic labor can be commercial restraints.

Critically, the Fourth Circuit aligned with recent appellate authority: Elad v. NCAA and Fourqurean v. NCAA, each applying Sherman Act scrutiny post-Alston. The opinion also situated the dispute in the NIL/revenue-sharing era, noting the “House settlement” in In re Coll. Athlete NIL Litig. and the NCAA’s temporary “Pavia waiver” tied to Pavia v. NCAA.

D. Section 1 Analytical Framework: Rule of Reason vs. Quick Look

The court described the three methodologies (per se, quick look, rule of reason) and treated them as a continuum, citing N.C. State Bd. of Dental Exam'rs v. FTC. For rule-of-reason structure, it cited Ohio v. Am. Express Co. and reiterated the presumption in favor of rule-of-reason from NCAA v. Alston (quoting Texaco Inc. v. Dagher and Standard Oil Co. of N.J. v. United States).

On quick look, the court drew the limiting principles from Cal. Dental Ass'n v. FTC and Leegin Creative Leather Prods., Inc. v. PSKS, Inc., warning against “twinkling of an eye” condemnation in complex joint-venture settings, consistent with Robertson v. Sea Pines Real Est. Cos. and the joint venture discussion in Am. Needle, Inc. v. NFL.

E. Market Definition and Anticompetitive Effects

The court held the district court erred by not properly defining a relevant market and by failing to make supporting factual findings, invoking Ohio v. Am. Express Co. for the necessity of market definition in this posture. It reiterated the plaintiff’s burden via Satellite Television & Associated Res., Inc. v. Cont'l Cablevision of Va., Inc., and the fact-intensive nature of market definition via E.I. du Pont de Nemours & Co. v. Kolon Indus., Inc.. It also referenced Todd v. Exxon Corp. (substitutable employers) through Fourqurean v. NCAA.

On anticompetitive effects, it relied on the Fourth Circuit’s competition-focused framing in Dickson v. Microsoft Corp. and the need to assess competitive effects in the relevant market from Oksanen v. Page Mem'l Hosp.. It also noted the requirement for a coherent economic theory and evidence, citing Epic Games, Inc. v. Apple, Inc., and explained when market definition may be sidestepped (but was not here), referencing FTC v. Indiana Fed'n of Dentists through a footnoted discussion in Ohio v. Am. Express Co..

Procedurally, the court stressed the injunction-order requirement to state findings and conclusions under Fed. R. Civ. P. 52(a)(2) and criticized the district court’s failure to do so, citing Frazier v. Prince George's County. Finally, it cited Goodman v. Praxair, Inc. to justify providing guidance for remand.

F. Waiver on Appeal

The court left the Restitution Rule injunction intact because the NCAA did not brief it, applying the waiver principle from Brown v. Nucor Corp..

2. Legal Reasoning

A. Why the Appeal Was Not Moot

Although the 2025–26 season ended, the court treated the dispute as inherently time-limited and recurring. The first prong of Kingdomware Techs., Inc. v. United States was satisfied because a football season is too short for full litigation and appeal. The second prong was satisfied not merely because “others” might sue, but because one of the same complaining parties (Tye Edwards) had already sought a waiver for the 2026–27 season, making recurrence a demonstrated probability under Murphy v. Hunt. The opinion’s seasonal analogies (Kramer v. Mosbacher, Feller v. Brock) supply a doctrinal bridge: where the challenged action is predictably annual, repetition is not speculative.

B. Why the Sherman Act Reaches These Eligibility Rules

The court’s commerciality holding is narrow but consequential: it does not declare all NCAA eligibility rules “per se commercial,” but holds the Five-Year Rule/JUCO Rule “are not exempt from Sherman Act scrutiny.” The key move is to characterize the restraints as limiting participation in a labor market—who may supply athletic services to Division I football programs—making them “trade or commerce” within the meaning of § 1, consistent with labor-market antitrust precedents (Anderson v. Shipowners' Ass'n of Pac. Coast, Radovich v. Nat'l Football League (NFL)). It also reads NCAA v. Alston as disallowing categorical carve-outs for NCAA regulation simply because it implicates education.

C. Why the Preliminary Injunction Could Not Stand

The Fourth Circuit vacated on the first Winter factor—likelihood of success—under a heightened standard because the injunction was mandatory. Two related errors drove the outcome:

  1. Methodological error (quick look vs. rule of reason): The district court’s “twinkling of an eye” language signaled quick-look condemnation. The Fourth Circuit held this is the “great in-between” where full rule-of-reason must apply, aligning with Fourqurean v. NCAA and Elad v. NCAA.
  2. Market-definition and findings error: Even under rule-of-reason, the Players had to define a relevant market and supply record support—especially at the preliminary injunction stage where the court must make findings under Rule 52(a)(2). The district court adopted a “nationwide market for the labor of NCAA Division I college football players” largely by citation rather than by fact-finding. The Fourth Circuit deemed that insufficient and held the Players “presented no factual evidence,” which “drastically and incorrectly reduced” their burden.

Because these defects infected the rest of the antitrust analysis (effects, justifications, alternatives), the court did not reach the remaining steps and vacated outright. Importantly, it left open the possibility that the Players might succeed on a fuller record at later stages.

3. Impact

A. A Fourth Circuit Door Opens for Antitrust Scrutiny of Eligibility Rules

This opinion establishes that, in the Fourth Circuit, at least some NCAA eligibility rules—specifically the Five-Year Rule as applied through the JUCO Rule—are subject to Sherman Act scrutiny. That alignment with Elad v. NCAA and Fourqurean v. NCAA reduces the NCAA’s ability to defeat eligibility challenges at the pleading or threshold stage by characterizing eligibility as “noncommercial” categorically.

B. But Plaintiffs Face a Higher Evidentiary Burden When Seeking Emergency Relief

The opinion is equally a cautionary precedent for plaintiffs: mandatory preliminary injunctions in sports-eligibility disputes require an “indisputably clear” showing. Courts must conduct full rule-of-reason analysis, and plaintiffs must supply market evidence and a coherent competition-harm theory, not merely citations to other cases.

C. Seasonal Sports Disputes Are Likely to Stay Appellate-Live

By applying “capable of repetition, yet evading review” to a completed season, the Fourth Circuit signals that the NCAA may not reliably moot appeals by waiting out seasons, particularly where at least one plaintiff remains exposed to the same eligibility rules for the next season. This can encourage appellate clarification (and discourage strategic timing) in eligibility litigation.

D. Practical Litigation Consequences on Remand and Beyond

  • District courts: must make explicit Rule 52(a)(2) findings on market definition and evidentiary support when issuing injunctions in antitrust cases.
  • Plaintiffs: should expect to present “cold, hard data” (or at least record-based, market-grounded analysis) on employer substitutability, recruitment constraints, and competitive effects in a rapidly changing NIL/revenue-sharing landscape.
  • NCAA: retains substantial room to argue procompetitive justifications and product-definition rationales, but must do so in a rule-of-reason framework rather than by categorical immunity.

Complex Concepts Simplified

  • Five-Year Rule: a rule limiting athletes to four seasons of competition within a five-calendar-year window that starts when they first enroll full-time at a “collegiate institution,” including many JUCOs.
  • JUCO Rule (as used here): the NCAA’s inclusion of JUCO enrollment/competition in both the five-year “clock” and (absent waiver) the four-season count.
  • Pavia waiver: a one-year, limited waiver (for 2025–26) that removed JUCO seasons from the four-seasons-of-competition calculation for similarly situated athletes, but did not waive the five-year clock.
  • Restitution Rule: an NCAA bylaw allowing penalties against schools/athletes who compete under an injunction later vacated; here, that part of the injunction stayed because the NCAA did not appeal it.
  • Preliminary injunction (Winter factors): emergency relief before trial requires showing (1) likely success, (2) irreparable harm, (3) equities favor the movant, and (4) public interest supports relief.
  • Mandatory vs. prohibitory injunction: prohibitory orders preserve the status quo; mandatory orders change it (here, compelling eligibility). Mandatory orders are harder to obtain.
  • Rule of reason vs. quick look: rule of reason is a full economic analysis of competitive harms/benefits; quick look is an abbreviated approach used only when experience shows the restraint is almost always lawful or unlawful. The Fourth Circuit required full rule of reason here.
  • Relevant market (labor market): the set of employers athletes reasonably see as substitutes. Without a supported market definition, courts cannot reliably assess market power or competitive effects.
  • Capable of repetition, yet evading review: a mootness exception for short-lived disputes that are likely to recur for the same party (e.g., annual seasons).

Conclusion

The Fourth Circuit’s decision does two major things. First, it recognizes that the NCAA’s Five-Year/JUCO eligibility restrictions can be “commercial” restraints subject to the Sherman Act because they regulate access to a college-football labor market. Second, it sharply limits emergency judicial intervention absent rigorous rule-of-reason methodology, explicit factual findings, and record-supported market definition—especially when the requested relief is a mandatory preliminary injunction. The result is a doctrinal opening for eligibility-based antitrust claims in the Fourth Circuit, paired with a clear warning: plaintiffs must build the economics and the record, not merely the citations, before they can obtain season-changing injunctive relief.
