9.B. It is a fault if the volleying player or anything that has contact with the volleying player while in the act of volleying touches the non-volley zone. For players using wheelchairs, the front (smaller) wheels may touch the non-volley zone.
- 9.B.1. The act of volleying begins when the ball is struck out of the air before bouncing (volleyed) and ends when the player’s movement from the follow-through action (momentum) stops.
9.C. During the act of volleying, it is a fault if the volleying player’s momentum causes the player to contact anything that is touching the non-volley zone, including the player’s partner. For players using wheelchairs, the front (smaller) wheels may touch the non-volley zone.
- 9.C.1. It is a fault even if the ball becomes dead before the player contacts the non-volley zone.
9.D. If a player has touched the non-volley zone for any reason, that player cannot volley a return until both feet have made contact with the playing surface completely outside the non-volley zone. A maneuver such as standing within the non-volley zone, jumping up to hit a volley, and then landing outside the non-volley zone is a fault.
