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.

Decision.—The stroke stands.

XXX.—A ball strikes the ground close to a line, the scorer scores the stroke against the striker. On appeal to the linesman, the latter decides that the ball was not out. Which decision stands?

Decision.—The scorer has no right to consider a ball out until the linesman has called to that effect; therefore the decision of the latter must be accepted. The decision of a linesman affecting his own line is final.

XXXI.—A return strikes the cord running along the bottom of the net and bounds over. Is it a good return?

Decision.—Yes.

XXXII.—During play a ball is thrown into the court and the ball in play strikes it, or a player steps on it. May a let be claimed?

Decision.—Yes.
