Arbitration Code

C. Special Provisions Applicable to the Appeal Arbitration Procedure

R47 Appeal

An appeal against the decision of a federation, association or sports-related body may be filed with the CAS insofar as the statutes or regulations of the said body so provide or as the parties have concluded a specific arbitration agreement and insofar as the Appellant has exhausted the legal remedies available to him prior to the appeal, in accordance with the statutes or regulations of the said sports-related body.

An appeal may be filed with the CAS against an award rendered by the CAS acting as a first instance tribunal if such appeal has been expressly provided by the rules applicable to the procedure of first instance.  

R48 Statement of Appeal The Appellant shall submit to the CAS a statement of appeal containing :

  • the name and full address of the Respondent;
  • a copy of the decision appealed against;
  • the Appellant’s request for relief;
  • the appointment of the arbitrator chosen by the Appellant from the CAS list, unless the parties have agreed to a Panel composed of a sole arbitrator;
  • if applicable, an application to stay the execution of the decision appealed against, together with reasons;
  • a copy of the provisions of the statutes or regulations or the specific agreement providing for appeal to the CAS.

Upon filing the statement, the Appellant shall pay the Court Office fee provided for under Article R65.2.

If the above-mentioned requirements are not fulfilled when the statement of appeal is filed, the CAS Court Office shall grant once only a short deadline to the Appellant to complete his statement, failing which it shall be deemed withdrawn.  

R49 Time limit for Appeal

In the absence of a time limit set in the statutes or regulations of the federation, association or sports-related body concerned, or of a previous agreement, the time limit for appeal shall be twenty-one days from the receipt of the decision appealed against. After having consulted the parties, the Division President may refuse to entertain an appeal if it is manifestly late.  

R50 Number of Arbitrators

The appeal shall be submitted to a Panel of three arbitrators, unless the Appellant establishes at the time of the statement of appeal that the parties have agreed to a Panel composed of a sole arbitrator or, in the absence of any agreement between the parties regarding the number of arbitrators, the President of the Division decides to submit the appeal to a sole arbitrator, taking into account the circumstances of the case.

When two or more cases have manifestly the same object, the President of the Appeals Arbitration Division may invite the parties to agree to refer these cases to the same Panel; in the absence of agreement between the parties, the President of the Division shall decide.  

R51 Appeal Brief

Within ten days following the expiry of the time limit for the appeal, the Appellant shall file with the CAS a brief stating the facts and legal arguments giving rise to the appeal, together with all exhibits and specification of other evidence upon which he intends to rely, failing which the appeal shall be deemed withdrawn.

In his written submissions, the Appellant shall specify any witnesses and experts whom he intends to call and state any other evidentiary measure which he requests. The witness statements, if any, shall be filed together with the appeal brief, unless the President of the Panel decides otherwise.  

R52 Initiation of the Arbitration by the CAS

Unless it is apparent from the outset that there is manifestly no arbitration agreement referring to the CAS, the CAS shall take all appropriate actions to set the arbitration in motion. To this effect, the Court Office shall, in particular, communicate the statement of appeal to the Respondent, and the President of the Division shall proceed with the formation of the Panel in accordance with Articles R53 and R54. If applicable, he shall also decide promptly on an application for a stay or for interim measures.

With the agreement of the parties, the Panel or, if it has not yet been appointed, the President of the Division may proceed in an expedited manner and shall issue appropriate directions for such procedure.  

R53 Appointment of Arbitrator by Respondent

Unless the parties have agreed to a Panel composed of a sole arbitrator or the President of the Division considers that the appeal is an emergency and must be submitted to a sole arbitrator, the Respondent shall appoint an arbitrator within ten days after receipt of the statement of appeal. In the absence of an appointment within such time limit, the President of the Division shall proceed with the appointment in lieu of the Respondent.  

R54 Appointment of the Sole Arbitrator or of the President and Confirmation of the Arbitrators by the CAS

If, by virtue of the parties’ agreement or of a decision of the President of the Division, a sole arbitrator is to be appointed, the President of the Division shall appoint the sole arbitrator upon receipt of the motion for appeal.

If three arbitrators are to be appointed, the President of the Division shall appoint the President of the Panel upon appointment of the arbitrator by the Respondent and after having consulted the arbitrators. The arbitrators selected by the parties shall only be deemed appointed after confirmation by the President of the Division. Before proceeding with such confirmation, the President of the Division shall ensure that the arbitrators fulfil the requirements of Article R33.

Once the Panel is formed, the Court Office takes notice of the formation of the Panel and transfers the file to the arbitrators. In addition, Article R41 is applicable by analogy, except that the President of the Panel is appointed by the President of the Appeals Division.  

R55 Answer of Respondent

Within twenty days from the receipt of the grounds for the appeal, the Respondent shall submit to the CAS an answer containing :

  • a statement of defence;
  • any defence of lack of jurisdiction;
  • any counterclaim;
  • any exhibits or specification of other evidence upon which the Respondent intends to rely, including the names of the witnesses and experts whom he intends to call; the witness statements, if any, shall be filed together with the answer, unless the President of the Panel decides otherwise.

If the Respondent fails to submit its response by the given time limit, the Panel may nevertheless proceed with the arbitration and deliver an award.  

R56 Appeal and answer complete

Unless the parties agree otherwise or the President of the Panel orders otherwise on the basis of exceptional circumstances, the parties shall not be authorized to supplement their argument, nor to produce new exhibits, nor to specify further evidence on which they intend to rely after the submission of the grounds for the appeal and of the answer.  

R57 Scope of Panel’s Review, Hearing

The Panel shall have full power to review the facts and the law. It may issue a new decision which replaces the decision challenged or annul the decision and refer the case back to the previous instance. Upon transfer of the file, the President of the Panel shall issue directions in connection with the hearing for the examination of the parties, the witnesses and the experts, as well as for the oral arguments. He may also request communication of the file of the federation, association or sports-related body, whose decision is the subject of the appeal. Articles R44.2 and R44.3 shall apply.

After consulting the parties, the Panel may, if it deems itself to be sufficiently well informed, decide not to hold a hearing. At the hearing, the proceedings take place in camera, unless the parties agree otherwise.

If any of the parties is duly summoned yet fails to appear, the Panel may nevertheless proceed with the hearing.  

R58 Law Applicable

The Panel shall decide the dispute according to the applicable regulations and the rules of law chosen by the parties or, in the absence of such a choice, according to the law of the country in which the federation, association or sports-related body which has issued the challenged decision is domiciled or according to the rules of law, the application of which the Panel deems appropriate. In the latter case, the Panel shall give reasons for its decision.  

R59 Award

The award shall be rendered by a majority decision, or in the absence of a majority, by the President alone. It shall be written, dated and signed. The award shall state brief reasons. The signature of the President shall suffice.

Before the award is signed, it shall be transmitted to the CAS Secretary General who may make rectifications of pure form and may also draw the attention of the Panel to fundamental issues of principle.

The Panel may decide to communicate the operative part of the award to the parties, prior to the reasons. The award shall be enforceable from such written communication.

The award, notified by the CAS Court Office, shall be final and binding upon the parties. It may not be challenged by way of an action for setting aside to the extent that the parties have no domicile, habitual residence, or business establishment in Switzerland and that they have expressly excluded all setting aside proceedings in the arbitration agreement or in an agreement entered into subsequently, in particular at the outset of the arbitration.

The operative part of the award shall be communicated to the parties within four months after the filing of the statement of appeal. Such time limit may be extended by the President of the Appeals Arbitration Division upon a reasoned request from the President of the Panel.

The award, a summary and/or a press release setting forth the results of the proceedings shall be made public by the CAS, unless both parties agree that they should remain confidential.
