Checklist: Key checks before filing 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 defects and ensure full compliance with the requirements of the Code of Sports-related Arbitration.
In brief
Filing an appeal with the CAS requires the prior exhaustion of internal legal remedies provided under the relevant sporting body's statutes. Unless otherwise stipulated by statute, a peremptory deadline of 21 days applies from receipt of the challenged decision. The filing process requires payment of a 1,000 CHF Court Office fee and the designation of an arbitrator selected strictly from the official closed list. The appeal must explicitly reference the arbitration clause, articulate complete prayers for relief, and attach a copy of the contested decision. Failure to affix a valid signature or observe the mandatory provisions of the Code of Sports-related Arbitration results in the inadmissibility of the appeal.

Exhaustion of internal remedies

Failure to exhaust all internal remedies prior to filing an appeal with the CAS results in the inadmissibility of the application.
- 2.
Peremptory 21-day deadline
Ensure that no more than 21 days have elapsed since receipt of the challenged decision. Expiration of this time limit, unless a different period is expressly provided for by the applicable statutes, entails the forfeiture of the right to appeal.
- 3.
Payment of the Court Office fee
Confirm payment of the 1,000 CHF Court Office fee. Failure to pay this administrative fee within the time limit set by the Code prevents the initiation of the arbitration proceedings.
- 4.
Appointment of an arbitrator from the closed list
Verify that the designated arbitrator is included in the official CAS closed list of arbitrators. The appointment of an individual not included in the list invalidates the designation.

5.Indication of arbitral jurisdiction
Check that the appeal explicitly cites the arbitration clause or statutory provision establishing the jurisdiction of the tribunal. Absent such reference, the jurisdiction of the CAS cannot be established.
- 6.
Completeness of the prayers for relief
Review the prayers for relief to ensure that every claim is explicitly and comprehensively stated. The panel is bound by the scope of the claims and may not grant relief beyond what is expressly requested by the parties.
- 7.
Attachment of the challenged decision
Ensure that a copy of the challenged decision is attached to the appeal. Failure to submit the contested decision hinders the proper initiation of the proceedings.
- 8.
Signature and formal requirements
Verify the inclusion of the date, place, and valid signature on the document. The lack of signature by the appellant or their duly authorized counsel may render the filing invalid.

Frequently asked questions
What happens if I fail to pay the 1,000 CHF fee?
Without payment of the Court Office fee, the CAS Court Office will not register the appeal and the arbitration will not commence, creating the risk of missing the peremptory deadline for appeal.
Can I appoint an arbitrator of my choice who is not on the list?
No, the Code of Sports-related Arbitration strictly requires selecting an arbitrator exclusively from among the members listed on the official CAS closed list.
