Checklist: pre-filing checks for a CAS appeal
2 min read · Editorial oversight: Avv. Federico Papa
This checklist should be consulted immediately prior to filing the appeal to prevent fatal procedural flaws and ensure compliance with all requirements of the Code of Sports-related Arbitration.
In brief
Filing a CAS appeal requires prior exhaustion of internal remedies provided by sports body statutes. A peremptory 21-day deadline applies from receipt of the challenged decision. The procedure mandates payment of a CHF 1,000 Court Office fee and selection of an arbitrator from the official closed list. The appeal must cite the arbitration clause and include exhaustive prayers for relief. Appellants must attach the contested decision and provide a signature. Failure to observe these requirements under the Code of Sports-related Arbitration results in procedural invalidity or inadmissibility.

Exhaustion of internal remedies

- 2.
Peremptory 21-day deadline
Verify that no more than 21 days have elapsed since receipt of the challenged decision. Unless statutory provisions specify otherwise, exceeding this peremptory deadline results in the forfeiture of the right to appeal.
- 3.
Payment of Court Office fee
Confirm the timely payment of the CHF 1,000 Court Office fee. Failure to complete payment within the timeframe established by the Code prevents the valid initiation of arbitration proceedings.
- 4.
Appointment of an arbitrator from the closed list
Verify that the appointed arbitrator is included in the official CAS closed list. Designating a person outside this list renders the appointment invalid.

5.Indication of arbitral jurisdiction
Verify that the appeal explicitly cites the arbitration clause or statutory provision establishing the jurisdiction of the tribunal. Absent this reference, CAS jurisdiction cannot be established.
- 6.
Completeness of prayers for relief
Review the prayers for relief to ensure that every remedy sought is explicitly stated. The arbitral tribunal may only rule upon matters expressly submitted by the parties in their pleadings.
- 7.
Attachment of the challenged decision
Ensure that a copy of the challenged decision is attached to the appeal. Failure to enclose the contested decision hinders the proper initiation of proceedings.
- 8.
Signature and formal requirements
Verify that the document includes the date, place, and required signature. The absence of the signature of the appellant or legal counsel may result in the invalidity of the filing.

Frequently asked questions
What happens if the CHF 1,000 Court Office fee is not paid?
The CAS will not proceed with the registration of the appeal and the proceedings will not be initiated, risking the forfeiture of the peremptory time limit to appeal.
Can I appoint an arbitrator who is not included in the closed list?
No. The Code of Sports-related Arbitration mandates selecting arbitrators exclusively from the official closed list of the tribunal.
