“If, and to the extent that, any such dispute has not been settled within 90 days of the commencement of the mediation, or if, before the expiration of the said period, either party fails to participate or continue to participate in the mediation, the dispute shall, upon the filing of a Request for Arbitration by either party, be referred to and finally settled by CAS arbitration pursuant to the Code of Sports-related Arbitration. When the circumstances so require, the mediator may, at his own discretion or at the request of a party, seek an extension of the time limit from the CAS President.”
