In the event of a double fault, what is the subsequent course of action by the referee?

In the event of a double fault, declaring a replay is the appropriate course of action. A double fault occurs when both teams commit a fault during the same play, which means that neither team can be awarded a point. By calling for a replay, the referee ensures that the point is played again under the same conditions, allowing both teams another opportunity to win the rally without penalizing either side for the infractions that occurred.

This approach maintains fairness in the game, as neither team benefits or suffers from the faults. Generally, volleyball rules are designed to promote sportsmanship and a fair contest, and declaring a replay in the case of a double fault aligns with this principle.

The other options do not align with the standard procedures for handling double faults and could inadvertently favor one team over the other. Therefore, declaring a replay is the most equitable solution in such situations.
