Who ensures that the game balls comply with the specifications of Law 2?

The referee is responsible for ensuring that the game balls comply with the specifications outlined in Law 2 of the Laws of the Game. This law details the required size, weight, and quality of the match ball. Before the start of a match, it is the referee's duty to inspect the game balls to confirm they meet the necessary standards for play. This process is critical, as using a ball that does not adhere to the specifications can affect the fairness and flow of the game.

While other roles, like the team coach or the field manager, may have various responsibilities regarding equipment and field maintenance, the ultimate authority to approve the game's ball lies with the referee, whose decisions directly influence the match's proceedings. The players' association typically focuses on players' rights and regulations but does not play a direct role in ball specification compliance for a specific match.
