Lets
'Let' is called by the umpire, or by a player (if there is no umpire), to halt play.
A 'let' may be given for any unforeseen or accidental occurrence. The rules of badminton consider the following as 'lets':
1. If a shuttle is caught in the net and remains suspended on top or, after passing over the net, is caught in the net, it shall be a 'let' except on service.
2. If, during service, the receiver and server are both faulted at the same time, it shall be a 'let'.
3. If the server serves before the receiver is ready, it shall be a 'let'.
4. If, during play, the shuttle disintegrates and the base completely separates from the rest of the shuttle, is shall be a 'let'.
5. If a line judge is unsighted and the umpire is unable to make a decision, it shall be a 'let'.
A 'let' may occur following a service court error. When a 'let' occurs, the play since the last service shall not count and the player who served shall serve again, except where in situations where the Law of Service Court Errors is applicable.
