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 corps, 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. The second referee must check that during the match, the coach is sitting on the bench or standing or walking within the free zone in front of his/her team’s bench from the attack line to the warm-up area, without disturbing or delaying the match (Rule 5.2.3.2 and Rule 5.2.3.4).
5.1. The coach’s movement rule applies to the Head Coach only; it does not apply to assistant coaches, managers/trainers, or medical doctors. They are to sit on the bench.
5.2. The coach does not have the right to enter the court for any reason unless it is to assist an injured player. The coach has no right to speak nor protest to the referee. For FIVB, the coach only can answer questions from the second referee to clarify certain Challenge requests.
5.3. All time-outs and substitutions are to be requested by the Coach from the end of the bench closest to the scorer when he/she is sitting or from the extension of the attack line in the free zone when he/she is standing or walking.
