3. Organisation of the CAS - Statute S21
The President of either Division may be challenged if circumstances exist that give rise to legitimate doubts with regard to her/his independence vis-à-vis one of the parties to an arbitration assigned to her/his Division. She/he shall pre-emptively disqualify herself/himself if, in arbitration proceedings assigned to her/his Division, one of the parties is a sports-related body to which she/he belongs, or if a member of the law firm to which she/he belongs is acting as arbitrator or counsel.
ICAS shall determine the procedure with respect to any challenge. The challenged President shall not participate in such determination.
If the President of a Division is challenged, the functions relating to the efficient running of the proceedings conferred upon her/him by the Procedural Rules (Articles R27 et seq.), shall be performed by her/his deputy or by the CAS President, if the deputy is also challenged. No disqualified person shall receive any information concerning the activities of CAS regarding the arbitration proceedings giving rise to her/his disqualification.
