The protection of minors has been a significant concern for FIFA since 2001 when, in cooperation with the European Commission, it introduced in its regulations the prohibition of transfer for underage players in football. Since then, Article 19 of the FIFA Regulations on the Status and Transfer of Players (FIFA RSTP) has been revised on multiple occasions, and some exceptions to the general rule have been put in place, but the main prohibition still stands. Analyzing FIFA’s decisions related to minors, especially when they are challenged before the Court of Arbitration for Sport (CAS), provides valuable insights. In this respect, it is interesting to observe that a considerable number of FIFA’s disciplinary decisions related to Article 19 FIFA RSTP involving clubs are - for some reason - subsequently amended in CAS awards. This recurring trend shows a noticeable discrepancy between FIFA and CAS when it comes to the interpretation of the rules involving the protection of minors. Precisely, these conflicting interpretations of the rules and the different appreciation of the circumstances to impose the appropriate sanctions will be part of the analysis presented in this article.
