Transfer rules and evidential burdens: Case C-650/22 FIFA v BZ (Diarra) and the July 2025 amendments to the Regulations on the Status and Transfer of Players

Where private football rules govern a player’s access to employment with a new club, EU law is engaged. 1 In 1995, Bosman removed the most visible barriers to post-contract movement. 2 However, it did not redesign the transfer system as a whole. The 2001 settlement between FIFA/UEFA and the Commission preserved a regulatory architecture in which compensation exposure, ITC-based clearance (through the International Transfer Certificate procedure) and fixed registration windows continued to shape mobility in practice. 3 The immediate trigger for Diarra was BZ’s failed move to Charleroi, after uncertainty over registration and potential joint liability under FIFA’s transfer rules carried the dispute through the Belgian courts to the Mons reference. 4 Diarra therefore tests whether that post- Bosman architecture, taken as a connected design of compensation exposure, clearance control and registration-period timing, restricts free movement and competition contrary to Articles 45 and 101 TFEU. 5
