Appealable calls

Any player may appeal a short or other service fault. Any player may also appeal receiving line violations. If the server appeals a short or other service fault, and the appeal is upheld, the server is awarded the serve over. If the server had one short, the call would cancel the previous fault call, and the server would be awarded two serves, because he/she was judged to have made a legal serve. If, in the opinion of the referee, the ball could not have been returned, a point shall be awarded the server. If the appeal is not upheld, the call would be two shorts, a side out. If, on the first serve, the server appeals a non-call of a short or other service fault, and the appeal is upheld, the server is awarded a second serve. After the rally has ended, either player may appeal on a double-bounce call or non-call, kill shots called good, kill shots called no good and court hinders. The outcome may result in a point being awarded, a side out, or a replay. After the rally has ended, either player may also appeal faults, restraining line violations, and skip serves not called. If the appeal is upheld, the player is awarded the appropriate call. In all one-wall matches, appeals are limited to three unsuccessful appeals per player/side per 21-point game and two unsuccessful appeals for shorter games. At no time may a player appeal a hinder serve, hinder (other than court hinders), technicals or other discretionary calls.
