‘Render unto sports the things that are sport and to courts the things that are legal.’ 1 Michael Beloff
Nowadays the CAS is the highest tribunal in the hierarchy of arbitration in football-related disputes. Therefore, through its jurisprudence, which has developed during the last few years through several cases, the CAS contributes to the development of the rules governing world football whether through adopting clear and practical views or interpretations in regard to a particular rule or legal principle, or through developing a set of criteria or tests to be used in determining whether the rule at stake is to be applied.
Specifically in regard to employment contracts of football players the CAS has- arguably- played a very big and effective role in developing the rules applicable there to. This has been achieved particularly through cases related to unilateral breach of said contracts.
