Official Rules of Racquetball

B.6 - Line Judges

(a) When Utilized. Two line judges should be used for semifinal and final matches, when requested by a player or team, or when the referee or tournament director so desires. However, the use of line judges is subject to availability and the discretion of the tournament director.

(b) Replacing Line Judges. If any player objects to a person serving as a line judge before the match begins, all reasonable effort shall be made to find a replacement acceptable to the officials and players. If a player objects after the match begins, any replacement shall be at the discretion of the referee and/or tournament director.

(c) Position of Line Judges. The players and referee shall designate the court location of the line judges. The tournament director shall settle any dispute.

(d) Duties and Responsibilities. Line judges are designated to help decide appeals. In the event of an appeal, and after a very brief explanation of the appeal by the referee, the line judges must indicate their opinion of the referee's call.

(e) Signals. Line judges should extend their arm and signal as follows: (i) thumb up to show agreement with the referee's call, (ii) thumb down to show disagreement, and (iii) hand open with palm facing down to indicate "no opinion" or that the play in question wasn't seen.

(f) Manner of Response. Line judges should be careful not to signal until the referee announces the appeal and asks for a ruling. In responding to the referee's request, line judges should not look at each other, but indicate their opinions simultaneously in clear view of the players and referee. If at any time a line judge is unsure of which call is being appealed or what the referee's call was, the line judge should ask the referee to repeat the call and the appeal.

(g) Result of Response. The referee's call stands if at least one line judge agrees with the referee or if neither line judge has an opinion. If both line judges disagree with the referee, the referee must reverse the call. If one line judge disagrees with the referee and the other signals no opinion, the rally is replayed. Any replays, with the exception of appeals on the second serve itself, will result in resumption of play at first serve.
