What is a rotation fault in volleyball?

A rotation fault occurs when a team serves out of the correct order. The opponent scores a point, gets the serve, and all points scored by the faulty team since the error are cancelled.

Full Explanation

Per FIVB Rule 7.7, a rotation fault is committed when the serve is not made according to the correct service order. The consequences are: the opponent is awarded a point and the serve; and per FIVB Rule 7.7.2, all points scored by the team at fault since the fault was committed are cancelled (the opponent's points during that period are retained). The scorekeeper identifies the fault by cross-referencing the server with the scoresheet lineup. To prevent rotation faults, coaches should review the rotation order before each set and players should know their position.
