Official Rules of Racquetball

3.8 - Dead-ball Serves

Dead-ball serves do not cancel any previous fault serve. The following are dead-ball serves:

(a) Court Hinders. A serve that takes an irregular bounce because it hit a wet spot or an irregular surface on the court is a dead-ball serve. In addition, any serve that hits any surface designated by local rules as an obstruction rather than being out-of-play.

(b) Broken Ball. If the ball is determined to have broken on the serve, a new ball shall be substituted and the serve shall be replayed, not canceling any prior fault serve.
