To whom does the player submit an appeal, if they wish to dispute a FIFA decision?

If a player wishes to dispute a FIFA decision, the appropriate course of action is to submit an appeal to the Court of Arbitration for Sport (CAS). This is because CAS is an independent body that provides arbitration and mediation services for sports disputes at the international level, and it serves as the final authority on appeals related to FIFA decisions. Players and clubs turn to CAS when they seek to challenge rulings made by FIFA and require a neutral party to review the case.

Alternatively, FIFA’s Disciplinary Committee deals with enforcement and application of FIFA's regulations but does not handle appeals from players. Additionally, the local football association generally deals with domestic matters and does not have jurisdiction over FIFA decisions. The FIFA Congress is a governing body that primarily discusses and makes decisions about policy and structural issues within FIFA, rather than handling individual disputes. Hence, for a formal appeal against a FIFA decision, CAS is the correct avenue.
