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
before or in the act of hitting the ball.  If a let is requested after the ball has been hit, it shall not be granted.
    (b) If a player endeavoring to make his play in proper turn is
interfered with so as to prevent him from making such play as he would without such interference, or if the striker refrains from striking at the ball because of fear of hitting his opponent, there shall be a let whether the ball has been hit by him or not.
    (c) A player shall not be entitled to a let because his opponent
prevents him from seeing the ball, provided his stroke is not interfered with.
    (d) If the ball breaks in the course of a point, there shall be a
let.  If a player thinks the ball has broken while play is in progress, he must nevertheless complete the point and then request a let.  The referee shall grant the let only if the ball proves in fact to be broken.
    (e) If in the course of a point either player should be interfered
with by elements outside their control, there shall be a let.
    (f) It shall be the duty of the referee to call a let if, in his
opinion, the play warrants it.  If a match be played without a referee, the question of a let shall be left to the sportsmanship of the players.
    (g) A player hit by a ball still in play loses the point, except
that if he be hit by a ball played by his opponent before the ball strikes the front wall above the telltale, then it is a let.  If however, a player is hit by a ball off his opponent’s racquet that is clearly not going to reach the front wall above the telltale, a let will not be allowed and the point shall be given to the player who was hit by the ball.  However, a player hit by a ball still in play will not lose the point if because of interference a let is called.
