What approach should the first referee take concerning the line judges’ calls?

The correct answer focuses on the importance of collaboration and authority for the first referee in managing the match effectively. A first referee should acknowledge the input of the line judges, as they have a perspective on plays that the referee may not have from their vantage point. By considering the line judges' calls, the first referee shows respect for their role and reinforces a team dynamic that is crucial for the smooth running of the game.

However, it is essential for the first referee to maintain ultimate authority over the match. This means that even though line judges provide valuable information regarding out-of-bounds calls and touches, the first referee must exercise their judgment and make final decisions based on the entire context of the play. This approach helps to ensure clarity and consistency in officiating, which are essential for fair play and maintaining the flow of the game.

This combination of valuing the input from line judges while ensuring that decisions strictly remain within the first referee's authority strikes the right balance in officiating volleyball matches.
