During the Match: Situations that may occur

What the ITTO saysWhat this looks like in practiceFurther advice / good practice / additional considerations
Raise the right hand above the head when the referee is required on court.There are many situations that could mean the referee should come on court, from a problem with court mats to player injury. Remember to start your stopwatch once you call for the referee, so that you can make a note on the scoresheet as to how long play was stopped. See Section 7 of this manual for more information on the notes that need to be made on the scoresheet if the referee is called.Be aware that the right hand is used to call the referee on court, while raising the left hand above the head is used to signal that a decision is required from the Instant Review System (IRS) as to whether a shuttle landed “in” or “out”. This is, of course, only applicable at tournaments with IRS in place, which are quite high-level events.
“Fault” shall be called by
the umpire when a fault
occurs, except when…
Watch for any faults or lets during play, and make sure that you call these immediately and boldly.

Examples of “fault” situations during play (at the net) can be seen in Video Clip UMPV1.

Examples of “let” situations can be seen in Video Clip UMPV2.
…a service fault is called by the service judge. The umpire shall call “Service fault called”, followed by an explanation using the appropriate vocabulary (BWF Statutes, Section 4.1.5, Section 4);If there is a lot of noise in the hall, it may be difficult to hear a service fault call. Having a quick look at the service judge just after the service will help avoid any miscommunication.

When a service fault has been called, the player should not address the service judge to ask about the fault. The service judge’s signal and the umpire’s call should suffice to communicate the nature of the fault, but if there are further questions, the player should address the umpire. The umpire will either answer (preferably) or direct the player to the service judge.
…a fault during service is called by the umpire. The umpire shall announce the service fault or receiver fault using the appropriate vocabulary (BWF Statutes, Section 4.1.5, Section 4); orAs these calls are made less frequently, it is a good idea to review this vocabulary before an event.
…a fault occurs under Laws 13.2.1, 13.2.2 (which are obvious), 13.3.1 (for which the line judge’s call and signal suffices), or 13.3.2, unless clarification is needed for the players or spectators.
If neither side wishes to take an interval, play in that game shall continue without an interval, except where intervals are made mandatory by the referee.Sometimes intervals are mandatory for broadcasting purposes, which is mainly for higher-level events.Make sure that you know if intervals are optional or mandatory before you go on court.
If a side reaches 29 points, in each game and for each side, call “Game point” or “Match point”, as applicable.Once the score reaches 29, you need to indicate “game point” or “match point” again. When the score reaches “29-28” you would announce:

“Twenty Nine” <pause> “Game Point” <pause> “Twenty Eight”

If the scores draw level again:

“Twenty Nine” <pause> “Game Point” <pause> “All”
In a third game (or in a match of one game), after the rally which takes a side to 11 points, the umpire shall call the score, followed immediately by “interval, change ends”, or “service over”, the score, and then “interval, change ends”.Make sure that the players change ends at the appropriate times during the match.Be especially careful not to forget the change of ends at 11 points in a third game!

Keep an eye on the players and coaches as they change ends, and ensure that players’ belongings are once again properly placed (for example, in baskets courtside, if applicable).
During this interval and after the players have changed ends, each side may be joined on the court by no more than two accredited coaches. They must leave the court when the umpire calls “20 seconds”.(As explained previously around intervals)This interval will seem shorter than other 11-point intervals, as it takes time for the players to change sides and organise their gear. Make sure the players and coaches hear the “20 second” call and are reacting to it.
