The purpose of this study is to present implications by analyzing the Swiss Federal Court's annulment of the arbitration Awards in Court of Arbitration for Sport(CAS). As international interest in the sports sector increases, related disputes are also increasing. Therefore, the role of CAS specializing in sports disputes is becoming very important. In particular, the Swiss federal court's annulment of the arbitral awards made by the CAS could contribute significantly to the development of sports arbitration in the future. Looking at the case analyzed in this study, first of all, it is about the partiality of the arbitrator. The court judged that the arbitrator posted and shared racist articles on SNS, which could be sufficiently biased. Next, it is about the uncertainty of the arbitration clause. The arbitral award was finally canceled due to the issue of whether the CAS could make an arbitral award with jurisdiction over a clause that includes both dispute resolution through a sports organization and dispute handling in a national court. As a result of the analysis of this study, in the case of unclear arbitration provisions, it will be necessary to prepare an arbitration agreement. In addition, in the case of unclear arbitration provisions, it will be necessary to prepare a post-arbitration agreement. Finally, in order to revitalize sports arbitration, it will be necessary to train professional arbitrators in Korea, support them to work internationally, and establish specialized arbitration institutions.

An ICSID award on Lone Star case has been rendered finally on August 31st, 2022 after almost ten years since the Lone Star Funds submitted the request for arbitration against the Republic of Korea in 2012. The Lone Star case is the first investor-state dispute settlement(ISDS) case brought against Korea, and this case, also known as "eat and run" case, has given rise to heated debates for years. Moreover, as the ICSID tribunal has ordered Korea to pay the Lone Star Funds the sum of USD 216.5 million plus interest in the award, this case has become once again the subject of controversy. Any arguments and evidence submitted by the parties in dispute have not been disclosed until recently, however, as the memorials and the award are now open to the public, it has become possible to realize the assertions of each party and the decisions of the tribunal in detail. Therefore, this paper aims at analyzing the main issues of the Lone Star case with a focus on the ICSID award. By examining the substantive and procedural issues of the case one after the other, it might be able to understand the whole picture of the case and prepare for the remaining procedures of this case and other upcoming cases as well.

It is important who is bound by an arbitration agreement and what is the subject of the agreement in resolving disputes through arbitration. However, there are no provisions on them in the Korean Arbitration Act. Where an arbitration agreement is valid, the persons who are bound by the agreement cannot bring the claims which are the subject of the agreement to a court. Therefore, in determining the subjective scope of the effect of an arbitration agreement, we should make allowances for the essential qualities of arbitration to ensure the efficient resolution of disputes on the basis of the parties' agreement, and take caution not to infringe on the rights to be tried in court. Where the rights or legal relationships constituting the dispute that is the subject of the arbitration agreement have been assigned, the effect of the arbitration agreement between the predecessor and the other party should be extend to the successor, when it is agreed to transfer the status under the arbitration agreement to the successor between the three. However, in the absence of such an agreement, it is necessary to weigh the interests between the predecessor, the other party and the successor to determine whether the arbitration agreement has any effect on the successor. Arbitration is a method of resolving disputes based on the agreement of the parties. If it matters whether third parties who are not parties to the arbitration agreement is bound by the arbitration agreement or may invoke it, it should be resolved according to the intentions of the parties. Where the parties to an arbitration agreement have agreed to allow a third party to invoke the arbitration agreement, the effect of the arbitration agreement will extend to the third party. However, even if the parties to the arbitration agreement have not expressly agreed on this, when it is recognized that the parties have sought to resolve the dispute through arbitration even in relation to a third party by exploring the reasonable intentions of the parties, the effect of the arbitration agreement will extend to the third party.
