If parties choose CAS arbitration in a contract, any disputes will be heard here. Ordinary Arbitrations are fairly rare and do not make up much of CAS's workload. The Appeals Arbitration Division serves as a court of final appeal for sporting bodies, whether national (e.g. Thailand's Football Federation) or international (e.g. FIFA). The Appeals Division hears most of CAS's cases, including doping cases and other federation actions. It is the final court of appeal, meaning all internal remedies must be exhausted before proceeding to the Appeals Division. Federations must choose CAS of their own volition, just like private parties. Their rules and regulations must provide for CAS referral in order for it to have jurisdiction.⁶ Rule 61 of the Olympic Charter sends all Olympic Games disputes to CAS. FIFA has used the Court since 2005 and accounts for most of its matters.⁷ But some federations (e.g. North American sports leagues) avoid CAS arbitration altogether and settle disputes themselves.
