Summary of the Decision

In this landmark award, a three-member CAS Panel sitting in Lausanne upheld WADA's appeal against the 12-month sanction imposed by the La Liga Integrity and Fair-Play Committee on Player X — a professional footballer at Atletico de Madrid — for committing three whereabouts failures within a 12-month rolling period, contrary to Article 2.4 of the 2021 World Anti-Doping Code as implemented in the RFEF Anti-Doping Rules.

The first-instance panel had accepted a generalised plea of exceptional circumstances under Article 10.6 and reduced the presumptive mandatory sanction of 24 months to 12 months. The CAS Panel found that approach to be legally erroneous and reinstated the mandatory minimum sanction in full.

The decision is significant for three principal reasons: it establishes a failure-specific causal nexus requirement under Article 10.6; it clarifies that the first-instance panel's characterisation of the new Code's mandatory minimum as merely "presumptive" was incorrect; and it confirms that personal hardship, absent a direct causal connection to each individual failure, cannot ground a reduction below the mandatory minimum.

Background
The Whereabouts Failures

Between June 2023 and April 2024, Player X accumulated three whereabouts failures within a 12-month rolling period, contrary to Article 2.4 of the 2021 WADA Code as implemented in the RFEF Anti-Doping Rules. The failures consisted of two Missed Tests and one Filing Failure, and were recorded by the Spanish Anti-Doping Agency (CELAD) as follows:

#DateTypeCircumstances
1 12 June 2023 Filing Failure Athlete failed to update daily whereabouts slot within 72-hour correction window. No challenge filed; failure became final 30 June 2023.
2 4 November 2023 Missed Test DCOs attended declared training location at 07:00–08:00. Athlete absent. Athlete subsequently submitted statement claiming an unannounced change of training location; CELAD rejected explanation.
3 22 April 2024 Missed Test DCOs attended declared hotel (international fixture, away trip). Room confirmed vacant; team manager confirmed athlete had not slept at declared location. Third failure triggered ADRV notification.
First-Instance Proceedings

Following notification of the ADRV, CELAD referred the matter to the La Liga Integrity and Fair-Play Committee. The three-person first-instance panel convened on 11 July 2024 and issued its decision on 19 August 2024. The panel found the ADRV established but imposed a 12-month period of ineligibility, accepting the athlete's plea of exceptional circumstances under Article 10.6 on the basis of a generalised account of personal hardship during the relevant period, without requiring proof of a direct causal connection between the alleged circumstances and each individual failure.

Procedural Timeline
12 June 2023 Failure #1
First Filing Failure Recorded
CELAD records Filing Failure. No challenge filed within 10-day window. Failure becomes final 30 June 2023.
4 November 2023 Failure #2
Missed Test — Training Ground
DCOs unable to locate athlete during declared 60-minute slot. Missed Test recorded under Art. 2.4(b).
▼ Detail

Declared location: Atletico de Madrid training facility, Majadahonda, Madrid.

DCO attendance: 07:00–08:00. Athlete not present. Team administrator confirmed no scheduled individual session at that time.

Athlete's response: Statement submitted within 10 days claiming unannounced change of training venue. Explanation rejected by CELAD on grounds that the 2021 Code requires the athlete, not the team, to maintain and update whereabouts information.

22 April 2024 Failure #3 · ADRV triggered
Third Failure — Hotel (Away Fixture)
DCOs attended declared hotel during UEFA Europa League away trip. Athlete's room confirmed vacant. Third failure triggers ADRV notification under Art. 2.4.
📄 CELAD Notice 📄 ADRV Referral Letter
22 April 2024 Provisional suspension
Provisional Suspension Takes Effect
Player X provisionally suspended pending first-instance proceedings. Credit against final sanction begins from this date.
11 July 2024 Hearing
La Liga Integrity Committee Hearing
Three-person panel convenes. Athlete advances exceptional circumstances plea under Art. 10.6 based on generalised personal hardship. CELAD opposes any reduction.
▼ Detail

Panel: Chair — Prof. R. Morales; Members — Ms A. Ibáñez, Mr T. Schwarz.

Athlete's case: (i) Personal circumstances during the period constituted exceptional circumstances; (ii) no intent to evade testing; (iii) administrative failures contributed to Failures #1 and #3.

CELAD's case: No discretion exists below the mandatory minimum absent a finding of no fault or negligence; generalised hardship does not satisfy the Article 10.6 threshold.

La Liga Panel Imposes 12-Month Sanction
Panel finds ADRV established. Accepts generalised exceptional circumstances plea and reduces sanction to 12 months — below the 24-month mandatory minimum. WADA serves notice of intention to appeal.

WADA Files Statement of Appeal to CAS
WADA lodges appeal in Lausanne, seeking setting aside of first-instance decision and substitution of the mandatory 24-month sanction.
▼ Grounds of appeal

Ground 1: The first-instance panel misapplied Article 10.6 by accepting a generalised plea of exceptional circumstances without requiring proof of a direct causal connection between the alleged circumstances and each individual failure.

Ground 2: The panel erroneously characterised the 24-month sanction under Article 10.2.3 as "presumptive" rather than mandatory, thereby claiming a discretion the Code does not afford.

Ground 3: The resulting 12-month sanction was manifestly disproportionate to the gravity of a third whereabouts failure within 12 months.

Relief sought: Setting aside of the first-instance decision; imposition of a 24-month period of ineligibility commencing 22 April 2024; costs order against Respondents.

📄 Statement of Appeal 📄 WADA Appeal Brief
6–7 February 2025 Full hearing
Oral Hearing Before CAS Panel, Lausanne

▼ Hearing detail

Panel: President — Prof. L. Haas; Arbitrators — Dr. M. Reeb, Ms. S. Mauléon.

Key issues argued: (i) Standard of de novo review applicable to first-instance Article 10.6 findings; (ii) whether Article 10.2.3 creates a true mandatory minimum or merely a presumptive starting point; (iii) whether the athlete's evidence established exceptional circumstances meeting the failure-specific nexus requirement; (iv) provisional suspension credit.

Witnesses: Player X gave oral evidence in person. The player's treating physician gave expert evidence on personal circumstances (evidence taken in camera). WADA did not call live witnesses.

FIFA's intervention: FIFA made written and oral submissions supporting WADA's construction of Article 10.2.3 as mandatory.

Issues and Panel Findings
#IssueFinding
1 Was the ADRV established? Three whereabouts failures within 12-month rolling period under Art. 2.4. Yes — undisputed
2 Is the 24-month sanction under Art. 10.2.3 mandatory or presumptive? Proper construction of the 2021 Code's mandatory minimum framework. Mandatory
3 Does Art. 10.6 require failure-specific causal nexus? Whether exceptional circumstances must be linked to each individual failure or to the period generally. Yes — failure-specific
4 Did the athlete establish exceptional circumstances? Whether the evidence of personal hardship satisfied the revised Article 10.6 threshold on a failure-specific basis. No — threshold not met
5 Costs: Whether WADA was entitled to a contribution to its legal costs from the Respondents. Yes — CHF 8,000
Key Legal Holdings

"Article 10.6 is not a general proportionality override. It is a precisely-bounded provision that requires the athlete to establish a direct causal nexus between the exceptional circumstances invoked and each specific failure for which a reduction is sought."

CAS 2025/A/10421, para. 189
On the mandatory minimum sanction

The panel held that Article 10.2.3 of the 2021 Code creates a true mandatory minimum, not a presumptive starting point. The drafting history of the 2021 Code — and in particular the deliberate removal of the "up to two years" language that appeared in the previous version — demonstrates that the revision was intended to remove the discretion that first-instance panels had exercised to impose sanctions substantially below the level the Code contemplated as appropriate.

The panel rejected the first-instance panel's characterisation of the sanction as "presumptive", noting that this reading effectively reversed the direction of the 2021 reform. The only route below the mandatory minimum is through a finding of no fault or negligence (elimination) or no significant fault or negligence (reduction, subject to a floor of 12 months under Art. 10.6.1) — and both require a failure-specific causal analysis.

On the failure-specific causal nexus requirement

The panel confirmed, following CAS 2024/A/9812, that an athlete seeking to rely on exceptional circumstances must establish a direct causal connection between the circumstances relied upon and each individual failure for which a reduction is claimed. A general backdrop of personal adversity — however genuine and however sympathetically assessed — does not satisfy the threshold.

In the present case, the athlete's evidence established difficult personal circumstances during the 10-month period spanning the three failures, but did not explain why those circumstances caused the athlete to be absent from the declared hotel room on the night in question (Failure #3), or why the athlete failed to update the whereabouts slot in June 2023 (Failure #1). The panel found the causal nexus was absent for at least two of the three failures, which was sufficient to defeat the Article 10.6 plea in its entirety.

Significance of the Decision
1
Failure-specific causal nexus confirmed. This is the first CAS award to articulate the failure-specific causal nexus requirement under the 2021 Code in a football context, and its reasoning is directly applicable across all sports governed by WADA Code-compliant rules.
2
Mandatory minimum clarified. The panel's unequivocal rejection of the "presumptive sanction" reading is significant. First-instance panels cannot deploy the language of proportionality to override a Code-mandated minimum without satisfying the Article 10.6 threshold.
3
Support system availability is material. The panel's obiter remarks (paras. 211–214) indicate that the availability of support systems — coaches, agents, managers — who were aware of the personal circumstances will be a relevant factor in assessing whether exceptional circumstances are genuinely causally operative in relation to each failure.
4
WADA's appellate role endorsed. The panel endorsed WADA's standing to appeal any decision it considers to be contrary to the Code, regardless of whether CELAD was content with the first-instance outcome. This confirms the broad reach of WADA's appellate jurisdiction under Art. 13.2.
