This article is published at the 1/2023 Issue of the ASA Bulletin. Since its creation by the IOC in 1984, the Court of Arbitration for Sport (CAS) has evolved into an independent arbitral tribunal and the “supreme court” of sports-related disputes at the international level, administering several hundred of cases every year. The CAS functions predominantly as an appellate tribunal, reviewing decisions rendered by the internal tribunal of sports federations. Such appeal mechanism differs from commercial arbitration in many aspects. This article navigates through the appeal procedure following the amendment of the CAS Code in November 2022, from the outset of the arbitration through the issuance of the final award and beyond, focusing on procedural particularities that counsel without previous experience in sports arbitration should keep in mind. The article was re-published on the 2023/1 issue of the CAS Bulletin and can be accessed here.
