XXI.—A player serves from the wrong court, he loses the stroke, and then claims that it was a fault.
_Decision._—If the stroke was played in his first service it is simply a fault, but if he serves twice into the wrong court he has served two faults, and lost the stroke.
XXII.—The partner of the player whose turn it is to serve, serves and wins the game. The error is not discovered until the first service of the next game has been delivered.
_Decision._—A new game having been begun, the previous game stands.
XXIII.—The same case as above, except that the error is discovered after two or three strokes have been played.
_Decision._—Any score made before the last service is delivered stands—_i.e._, the last stroke does not stand unless another service (fault or not) has been delivered. The proper server will then serve.
XXIV.—With the score at thirty-forty, the server takes a bisque, and then serves from the right court. His opponent claims a fault.
_Decision._—It is a fault. The service must come alternately from the right and left courts.
XXV.—A player takes a bisque after the server has served a fault. Which court does the server next serve from?
XXVI.—The score is five games all, and the umpire directs the players to play an advantage set. The advantage game has been won when it is discovered that no advantage sets are to be played. What is to be done?
_Decision._—The set is won at the eleventh game. It is no part of the umpire’s duty to decide on the conditions of the matches.
XXVII.—A player serves. He hears the umpire call, but cannot hear what he says. He knows that the only two things that the umpire should call are “fault” and “let,” and that in neither case can the ball be in play. He therefore does not return it, only to find that the umpire has called play. Has he any redress?
XXVIII.—The umpire calls “fault” and then instantly changes and says “play.” The striker-out fails to return the ball, and he claims that he was prevented by the umpire, and also that the umpire cannot change his decision.
_Decision._—The umpire should call a let and the service be taken again.
XXIX.—A ball drops near a line, the player appeals, and the umpire calls “play.” The player misunderstands the call, and lets the ball fall. He then claims to have the stroke played again.
