12 26. HINDRANCE If a player is hindered in playing the point by a deliberate act of the opponent(s), the player shall win the point. However, the point shall be replayed if a player is hindered in playing the point by either an unintentional act of the opponent(s), or something outside the player's own control (not including a permanent fixture). Case 1: Is an unintentional double hit a hindrance? Decision: No. See also Rule 24 (f). Case 2: A player claims to have stopped play because the player thought that the opponent(s) was being hindered. Is this a hindrance? Decision: No, the player loses the point. Case 3: A ball in play hits a bird flying over the court. Is this a hindrance? Decision: Yes, the point shall be replayed. Case 4: During a point, a ball or other object that was lying on the player's side of the net when the point started hinders the player. Is this a hindrance? Decision: No. Case 5: In doubles, where are the server's partner and receiver's partner allowed to stand? Decision: The server's partner and the receiver's partner may take any position on their own side of the net, inside or outside the court. However, if a player is creating a hindrance to the opponent(s), the hindrance rule should be used. 27. CORRECTING ERRORS As a principle, when an error in respect of the Rules of Tennis is discovered, all points previously played shall stand. Errors so discovered shall be corrected as follows: a. During a standard game or a tie-break game, if a player serves from the wrong half of the court, this should be corrected as soon as the error is discovered and the server shall serve from the correct half of the court according to the score. A fault that was served before the error was discovered shall stand. b. During a standard game or a tie-break game, if the players are at the wrong ends of the court, the error should be corrected as soon as it is discovered and the server shall serve from the correct end of the court according to the score. c. If a player serves out of turn during a standard game, the player who was originally due to serve shall serve as soon as the error is discovered. However, if a game is completed before the error is discovered the order of service shall remain as altered. In this case, any ball change to be made after an agreed number of games should be made one game later than originally scheduled. A fault that was served by the opponents(s) before the error was discovered shall not stand.
