FIFA's judicial bodies primarily make decisions based on FIFA statutes and regulations. This is because FIFA operates under its own legal framework, which includes its constitutions, bylaws, regulations, and procedural rules. These documents provide a structured approach to governing football at the international level, including the rules for player transfers, disputes, and disciplinary actions.
The statutes and regulations are essential for ensuring uniformity and consistency in how decisions are made, as they set out the rights and obligations of member associations, players, and agents. Therefore, decisions made by FIFA’s judicial bodies reflect adherence to this internal legal framework rather than external laws or regulations.
In contrast, while European law and Swiss law may influence certain aspects of FIFA's functions due to the jurisdiction in which FIFA operates, they do not serve as the primary basis for decision-making within the organization. Similarly, the law chosen by the parties could come into play in specific contractual disputes but is not a guiding principle for the overall governance of FIFA's judicial processes.
