After the server delivers the first service, play shall be continuous so far as is practical. However,

7.1 at any time the Referee may suspend play owing to bad light or other circumstances beyond the control of the players and officials, for such period as the Referee shall decide. The score shall stand. If another court is available and the original court remains unsuitable for play, the Referee may transfer the match to it.

7.2 There shall be a 90 second interval between the end of the warm-up and the commencement of the first game and between all games. Players may leave the court during these intervals but must be ready to play prior to the expiry of the 90 second interval.

(G1) 7.3 If a player satisfies the Referee that a change of equipment, clothing or footwear is necessary, the player may leave the court to effect the change as quickly as possible but must do so within 90 seconds.

7.4 When 15 seconds of a permitted 90 second interval remain the Referee shall call "Fifteen seconds" to advise the players to be ready to resume play. At the end of 90 seconds the Referee shall call "Time".

Should one or both players not be ready to resume play when "Time" is called, the Referee shall apply Rule 17.

7.5 If a player is injured, ill or disabled the Referee shall apply Rule 16.

(G2) 7.6 The Referee, on deciding that a player has delayed play unreasonably, shall apply Rule 17.

(G3) 7.7 If an object, other than a player's racket, falls to the floor of the court while a rally is in progress the requirements are:

7.7.2 a player becoming aware of a fallen object may stop play and appeal.

7.7.3 If the object falls from a player, that player shall lose the rally, unless Rule 7.7.5 applies or the cause is a collision with the opponent. In the latter case the Referee shall allow a let, unless the player appeals for a let because of interference in which case the Referee shall apply Rule 12.

7.7.4 If the object falls from a source other than a player, the Referee shall allow a let unless Rule 7.7.5 applies.

7.7.5 If the player has already made a winning return when the object falls to the floor, that player shall win the rally.

7.7.6 If a dropped object remains unnoticed until the end of the rally, the result of the rally shall stand.

(G3) 7.8 If a player drops a racket, the Referee shall allow the rally to continue, unless interference occurred (Rule 12), the ball touched the racket (Rule 13.1.1), distraction occurred (Rule 13.1.3), or the Referee applies a conduct penalty (Rule 17).

A player wins a rally if:

8.1 the opponent fails to deliver a good service (Rule 4.4);

8.2 the opponent fails to make a good return (Rule 6), unless the Referee allows a let or awards a stroke to the opponent;

(G4) 8.3 the ball touches the opponent (including anything worn or carried), without interference, when the opponent is the non-striker, except as is otherwise provided for in Rules 9 and 10. If interference occurs then the provisions of Rule 12 apply. In all cases the Referee shall make the decision;

8.4 the Referee awards a stroke to the player as provided for in the Rules.

(G4) 9.1 If the striker hits the ball which, before reaching the front wall, hits the opponent (including anything worn or carried), play shall cease. The Referee, in addition to considering possible infringement of Rule 17, shall assess the ball’s trajectory and shall:

(G4 & G5) 9.1.2 if the striker turned, award a stroke to the opponent, unless the opponent made a deliberate movement to intercept the return, in which case the Referee shall award the stroke to the striker;

(G5) 9.1.3 if the striker’s return is a further attempt, allow a let, provided that Rule 9.1.2 does not apply;

9.1.4 allow a let if the ball either had struck or would have struck any other wall before the front wall and the return would have been good, unless Rule 9.1.5 applies;

9.1.5 if deciding the return would have been a winning return, award a stroke to the striker;

9.1.6 award a stroke to the opponent if the return would not have been good.

(G5) 9.2 If the striker turns:

9.2.1.1 allow a let, if deciding that there was a reasonable fear of the ball hitting the opponent and the striker would have been able to make a good return unless Rule 9.2.3 applies or

9.2.1.2 not allow a let, if deciding that the striker could not have made a good return.

9.2.2. The striker may, because of interference, stop play and appeal. The Referee shall:

9.2.2.1 allow a let, if deciding that the striker is unable to complete an attempt to play the ball because of interference by the opponent or

9.2.2.2 award a stroke to the striker, if deciding that the opponent did not make every effort to avoid the interference on turning, or

9.2.2.3 not allow a let, if deciding that the striker could not have made a good return regardless of the interference.

9.2.3 The Referee shall not allow a let if deciding that the act of turning was to create the opportunity to appeal rather than an attempt to return the ball.
