XVIII. A return hits the umpire or his chair or stand; the player claims that the ball was going into court.
Decision.—Unless the umpire can say that the ball was in his opinion not going into court, he should call a let.
XIX. A player receiving fifteen serves from the left court, his opponent claims a fault.
Decision.—It is a fault. The service starts from the right court under all circumstances.
XX.—At fifteen all, the server by mistake serves from the left court; he wins the stroke and serves again (a fault). The mistake is then discovered. Is he entitled to the previous stroke? From which court should he serve next?
Decision.—The previous stroke stands. A fault cannot be claimed after the next service, good or not, is delivered. The next service should be from the left court, the score being thirty-fifteen, and the server has served one fault.
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.
