The question of whether a party has exhausted its internal legal remedies does not pertain to CAS jurisdiction but instead serves as an admissibility requirement. By agreeing to CAS jurisdiction, the parties intended to exclude the option of appealing to State courts, especially when a CAS panel finds that the criteria for a "decision" under Article R47 of the CAS Code have not been met. Thus, whether a decision is appealable under Article R47 does not restrict CAS's jurisdiction over State courts; it is an issue of admissibility governed by procedural principles, such as efficiency. Similarly, determining the appealability of a (preliminary) decision from a prior instance is also a matter of procedural admissibility.
