1. The first referee must identify the game captain and coach and only they will be allowed to intervene during the game. The referees must know throughout the game who the game captains are.
2. During the match, the second referee must check that the reserve players are seated on the bench or are in the warm-up area. Players in the warm-up area during sets cannot use balls but may use personal warm up devices (e.g. stretch bands). The team members, either sitting on the bench or staying in the warm-up area, have no right to protest or contest the referees’ decisions. Such behaviour must be sanctioned by the first referee.
3. Should the game captain ask for an explanation of the referee's application of the rules, the first referee must give it by speaking briefly using official terminology of the Rulebook and if necessary, repeat his/her hand signals. The game captain has the right only to ask for an explanation on the application or interpretation of the rules made by the referees in the name of his/her team-mates.
4. The coach does not have the right to request anything from the members of the refereeing team, except the regular game interruptions (time-outs and substitutions). But, if on the scoreboard, the number of used regular game interruptions and/or the score are not indicated, or are not correct, he/she may inquire with the scorer, when the ball is out of play.
5. As per the rules of the game, the coach has no right to disturb the game or the work of the officials (referees, scorers, line judges), nor to have the right to enter the court. Nevertheless, it is not recommended for the 2nd referee to ignore the coaches when they address respectfully, asking for some explanation about a normal playing action. Whenever it is necessary, a short and clear answer to the coach can prevent further protest and sanctions. This is part of the "smooth refereeing" philosophy for conducting a volleyball game with common sense and in a good atmosphere.
