Section 7 -- Fault Rules
A fault is any action that stops play or a violation of the rules. A fault will be declared for the following:
7.A. Hitting the ball into the net on the service or any return.
7.B. Hitting the ball out of bounds.
7.C. Failure to hit ball before it bounces twice on player's court.
7.D. Violation of a service rule (See Section 4).
7.E. A player, or player's clothing, or any part of a player's paddle touches net when the ball is in play.
7.F. If the ball while in play, strikes a player or a player's clothing. The exception to this rule is if the ball strikes the player's paddle hand then it is considered in play. If the ball strikes a player standing out of bounds that player loses the rally. If in doubles, the serve strikes the opposing player positioned at the net not receiving the serve then it is a point for the serving team. This rule also includes all balls that appear to be hit out of bounds. In tournament play if you catch the ball or try to stop it from heading out of bounds then you lose the rally.
7.G. If the ball while in play, strikes the roof, walls, or other objects that are not part of the court.
7.H. Violation of non-volley zone rules (See Section 9).
7.I. Violation of the other rules (See Section 12).
