. If the
server makes two consecutive faults, he loses that point.
The server has the option of electing the side from which he shall
commence serving and thereafter, until he loses the service, he shall
alternate between both sides of the court in serving. If the server
serves from the wrong side of court, there shall be no penalty and if
the receiver makes no attempt to return the ball the point shall be
replayed from the proper court.
When one service fault has been called and play for any reason
whatsoever has stopped, when play is resumed the first fault does not
stand and the server is entitled to two services.

7. RETURN OF SERVICE AND SUBSEQUENT PLAY
(a) To make a valid return of service the ball must be struck after
the first bounce and before the second bounce, and reach the front wall
on the fly above the telltale and below the 16-ft. line; in so doing it
may touch any wall or walls within the court before or after reaching
the front wall, except as in (e), below. A service fault may not be
played. If a fair service is not so returned, it shall count as a point
for the server and he shall then serve from the other side of the court.
(b) After a valid return of service, each player alternately
thereafter shall strike the ball in the same manner as on the return of
service, except that it may be volleyed. The player failing to so
return the ball shall lose the point.
(c) A ball striking the ceiling or lights or on or above any court
boundary line on the fly shall be ruled out of court; if a ball should
strike the back wall on or above the 4'6" line after having bounced, it
shall continue to be in play. If a ball having bounced should go into
the gallery or strike any construction which alters its course, a let
shall be called.
(d) If a ball before the second bounce hits the front wall above
the telltale for the second time it is still in play.
(e) In an effort to return the ball to the front wall by first
hitting to the back wall, the ball may not be played to the back wall
unless it has first struck the back wall, and must be so struck as to
hit the back wall below the 4'6" line.
(f) A player may not hit a ball twice during a stroke, but, while
the ball is still in play, it may be struck at any number of times.

8. LET
A "let" is the stopping of play and the playing over of the point.
(a) In all cases, a player requesting a let must make his request
b
