Volleyball challenge system

The Challenge System process:
1. Video verification can be requested by the head coach, but it must happen before the game resumes and directly after the play which is a matter of doubt.
2. Both teams have two challenges per set. If the challenge is won it doesn’t decrease the number of challenges a team still has that set. If the challenge is lost, the number of challenges for that team is decreased by one.
3. The first referee has the right to ask for video verification in the case of being of two minds and if the call will end the set or match.
4. Verification requests can be for the following situations only:
a) A ball is in or out;
b) Ball contact with antennae, particularly the order after the attack hit or from the block;
c) Antennae or net contact by a player;
c) Contact of player’s feet with end line when serving, 3-mater line by a back-row player, and under net penetration onto the opponent’s side;
e) Libero’s feet position when playing the ball overhand pass if directly after an attack has been complete while the ball was entirely higher than the top of the net;
5. The first referee can allow or deny the request if deemed not reviewable. In the case of a rejected challenge, the requesting team will be sanctioned for a delay of game. Challenges are not to be used as a stall tactic or treated as an additional timeout. Players remain on the court during the video analysis.
6. The second referee analyzers the video replay on a court-side monitor. The replay will be available for onsite spectators and the TV audience.
7. The second referee informs the first referee of the outcome. The first referee is responsible for the final decision.
8. When there is not enough evidence to overturn the original call, the call stands and the team loses one challenge. If there is no replay available on a challenge call, the original call stands and the team does not lose a challenge opportunity.
