Rules Without Exceptions: How CAS Is Drawing Hard Lines on Fan Liability and Club Ownership

Introduction

Two decisions handed down by the Court of Arbitration for Sport (CAS) in 2025 have attracted significant attention from football administrators, legal practitioners, and club owners. Together, they represent a consistent and uncompromising jurisprudential trend: CAS will not disturb UEFA’s regulatory architecture unless a sanction crosses the threshold of being evidently and grossly disproportionate, and it will enforce clear deadlines and structural rules even when clubs have taken remedial steps after the fact. Practitioners advising clubs, investor-owners, and multi-stakeholder football structures will find both decisions instructive.

This inaugural edition of CAS Digest reviews the two awards, analyses the key principles they establish, and draws out the practical implications for clubs and their advisors.

Case I — Real Madrid C.F. v. UEFA: strict liability and proportionality

During the quarterfinal of the 2024/25 UEFA Champions League between Arsenal and Real Madrid at the Emirates Stadium, a single Real Madrid away supporter performed a Nazi salute. The fan was immediately detained by police. Real Madrid moved swiftly: the supporter was identified, subjected to internal disciplinary proceedings, and permanently stripped of his socio (club membership) status — the maximum sanction within the club’s own disciplinary arsenal.

Notwithstanding these exemplary internal actions, the UEFA Control, Ethics and Disciplinary Body (CEDB) sanctioned Real Madrid under the strict liability provisions of Articles 8 and 14 of the UEFA Disciplinary Regulations. The sanction comprised a €15,000 fine and a one-match ban on selling tickets to away supporters — the latter suspended for a probationary period of one year. The UEFA Appeals Body confirmed the decision on appeal.

Before the CAS, Real Madrid unequivocally condemned the fan’s conduct but argued the sanction was disproportionate in light of the mitigating factors: the offence was isolated and brief, caused no match disruption, and was met with the harshest available internal sanction. Real Madrid contended that CAS’s de novo review powers entitled it to reduce the penalty to reflect these circumstances. UEFA countered that strict liability was engaged and that Real Madrid’s mitigating actions had already been factored in — and they were the very reason Real Madrid received the absolute minimum statutory sanction available under Article 14.2, rather than a more severe one.

The CAS Panel dismissed Real Madrid’s appeal in full and upheld the UEFA decision, providing important clarity on three intersecting principles. First, the “evidently and grossly disproportionate” threshold — CAS reaffirmed that while it possesses full de novo review power in disciplinary matters, it will not lightly interfere with a well-reasoned decision of a sports governing body; the interference threshold is deliberately high. Second, mitigation cannot reduce a sanction below the statutory minimum — where a governing body has already credited mitigating conduct by issuing the minimum sanction available, CAS cannot reduce it further on the same grounds. Third, financial standing and competition context are relevant to proportionality — for a club of Real Madrid’s financial stature, in the context of the highly lucrative UEFA Champions League, a €15,000 fine is modest and proportionate to the gravity of a discriminatory offence.

Commentary and practice note — Real Madrid

The third principle deserves particular attention. The CAS Panel’s explicit recognition that a club’s financial standing and the economic context of the competition are legally relevant factors in proportionality analysis is significant. It suggests a contextual, rather than purely normative, approach to sanctions — one where a fine calibrated for a lower-division club may not pass muster against a club generating hundreds of millions in annual revenue. Clubs and their advisors should note this in any future proportionality challenge.

Equally, the decision reinforces the practical ceiling of mitigation: internal exemplary conduct — however commendable — does not unlock a reduction below a statutory minimum. The lesson for clubs is not that swift internal action is futile (it clearly influenced the suspension of the away-fan ban), but that it cannot substitute for compliance strategy or function as a get-out clause.

Case II — Crystal Palace FC v. UEFA: multi-club ownership and structural influence

For the 2025/26 UEFA Europa League (UEL) season, both Crystal Palace FC (CPFC) and Olympique Lyonnais (OL) qualified — CPFC by winning the FA Cup, and OL by finishing 6th in Ligue 1. The two clubs shared a significant ownership connection through Mr. John Textor and Eagle Football Holdings Bidco Limited.

The UEFA Club Financial Control Body (CFCB) assessed the ownership structure against the regulatory deadline of 1 March 2025 and found a breach of Article 5.01 of the UEFA Club Competitions Regulations — the Multi-Club Ownership (MCO) rule. Since two clubs under common control cannot compete in the same UEFA competition, the tie-breaker provisions of Article 5.02(b) were applied: OL was admitted to the UEL, and CPFC was relegated to the UEFA Europa Conference League (UECL). Mr. Textor subsequently sold his CPFC shareholding in June 2025, but by then the regulatory window had already closed.

CPFC advanced three grounds of appeal: (i) Textor held only a minority stake and lacked actual day-to-day management control; (ii) UEFA’s practice of allowing late cures meant the 1 March deadline should not be strictly enforced; and (iii) CPFC, as FA Cup winners, deserved priority over OL who qualified via league position. UEFA and OL rejected all three arguments.

The CAS Panel dismissed the appeal in its entirety, upholding the CFCB decision on all three grounds. First, capacity to influence, not actual control, triggers the MCO rule — Article 5.01(c)(iv) is satisfied where an individual has the structural capacity (voting rights, board seats, financial leverage) to exercise decisive influence; day-to-day managerial involvement is not required. Second, the 1 March assessment deadline is immovable — strict enforcement is essential for competition organisation and legal certainty, and a “late cure” executed after the deadline cannot retroactively cure a MCO breach. Third, the tie-breaker operates on domestic league rank alone — Article 5.02(b) resolves MCO conflicts by domestic championship ranking, and a cup qualification route confers no priority over a league qualification route under the tie-breaker.

Commentary and practice note — Crystal Palace

The capacity vs. actual control distinction is the most consequential holding in this decision. It directly impacts the growing universe of private equity and multi-stakeholder ownership structures in European football. An investor holding a minority stake with board representation, veto rights, or financial-rescue leverage may well cross the Article 5.01 threshold — even without day-to-day operational involvement. The structural mechanics of the investment, not the practical reality of who runs the club, is what counts.

The rigidity of the 1 March deadline also sends a clear message: compliance is a pre-season discipline, not a last-minute cure. Clubs and their legal advisors must conduct MCO audits well ahead of the regulatory window. By the time a conflict is identified in April or May, it is already too late. Investor-owners diversifying across European football should be advised that divestiture agreements — however commercially sensible — must precede, not follow, the regulatory deadline.

Finally, the tie-breaker ruling may drive clubs into rethinking qualification routes. Cup winners and play-off qualifiers who share an ownership group with a higher league finisher from another country may find themselves consistently displaced to lower competitions under the current framework. This structural asymmetry may prompt future regulatory reform discussions at UEFA.

Conclusion

These two decisions underscore a unified and uncompromising CAS approach to UEFA’s regulatory framework. Taken together, they stand for the proposition that structural rules governing club ownership and competition integrity will be enforced strictly and on time; that mitigation — however genuine — operates within the bounds of the rules, not beyond them; and that CAS’s supervisory role is not to second-guess proportionate decisions of regulatory bodies, but to correct their clear excesses.

For practitioners advising clubs, investors, and football administrators, the practical imperatives are clear: compliance programmes must be proactive and calendar-driven; ownership structures must be audited against the capacity test, not merely the control test; and any proportionality challenge to a regulatory sanction must clear a high jurisprudential bar. The digest is open — and the awards speak for themselves.
