So our case is "ordinary procedure" ?not appeals?
Under the ordinary procedure, each party chooses one arbitrator from the CAS list, then the two designated arbitrators agree on who will be the president of the panel. Failing such agreement, the President of the Ordinary Arbitration Division makes this selection instead of the two arbitrators.
Under the appeals procedure, each party chooses an arbitrator, and the president of the panel is selected by the President of the Appeals Arbitration Division.
