During a match, what is the first referee's primary focus?

The first referee's primary focus is enforcing the rules. This role is crucial in maintaining the integrity of the game, ensuring that all players and teams adhere to the established regulations. The referee must closely monitor the match, calling faults such as violations of the net, incorrect rotations, and other rule infractions. This oversight helps to create a fair playing environment.

While aspects like providing entertainment, encouraging players, and minimizing disruption are important in the context of the game, they do not take precedence over the critical responsibility of rule enforcement. The enforcement of rules is fundamental to the sport, as it directly impacts the flow of the game and the outcome of the match. By prioritizing rule enforcement, the first referee ensures that the game is played fairly and as intended.
