General trend of the growing popularity of arbitration is especially visible in the world of sport. The sports arbitration often be governed by specific rules of the relevant sports federation or association. Rather than allowing disputes to be settled in ordinary domestic courts, International Olympic Committee(IOC) and most International Sports Federations(IFs) now provide for all disputes under their regulations to be settled exclusively by way of arbitration. Indeed, many provide for a final appeal to the Court of Arbitration for Sport(CAS). The CAS can only accept claims or appeals if there is a valid arbitration clause between the parties, either inserted in the contract or in the rules of the sports association to which the parties form part(Art. R27 CAS Code). However due to the monopolistic position of international federations, athletes, as well as clubs, have no other choice than to submit their disputes to arbitration. The validity of these provisions can be questioned. Arbitration is a procedure in which a dispute is submitted, by agreement of the parties. It is a non-judicial process for the settlement of disputes whereby an independent third party - an arbitrator - makes a decision(arbitral award) that is binding. Usually, parties will pre-emptively include an arbitration clause in their contract or, once a dispute arises, enter an agreement to arbitrate. Yet in sport, this ‘agreement’ is forced: the regulations of IFs are rarely negotiated in any meaningful sense, so athletes (and all other participants) must either accept them or choose a different career. The very concept of ‘forced arbitration’ is questionable. All international conventions and domestic legislation consider the consent of the parties to the arbitration vital. There is no arbitration unless both parties agree to it. Though arbitration has become an almost quintessential part of sports law, it recently faced a legal challenge in the German case of Claudia Pechstein v ISU. This article will discuss the judgment of the German Court in Claudia Pechstein case, and consider whether sport’s use of ‘forced arbitration’ is satisfactory.
