The service judge in badminton sits in a relatively lower chair opposite the umpire. They are responsible for calling out a player if they commit a service fault and providing a player with a replacement shuttlecock if necessary. The Badminton World Federation (BWF) specifies that the service judge must sit opposite the umpire so that the umpire can see them at the moment of service and promptly halt the game if a player commits a fault. The service judge primarily looks for two particular faults during the serve: whether the player hits above the 1.15-meter mark and whether the racket is pointing in a downward direction.

What You'll Learn
Seated opposite the umpire
The service judge in badminton is seated opposite the umpire, with up to four line judges sitting behind them. The service judge sits in a relatively lower chair than the umpire, which allows them to be near the same height as the shuttlecock during the service. This gives them a better view to judge whether the server has committed a fault. The service judge is responsible for calling out a player if they commit a service fault and providing a player with a replacement shuttlecock if necessary. They also check that everything about a service is legal, from the method of service to the position of the service and receiver.
The service judge's proximity to the shuttlecock's height allows them to accurately judge whether the player has hit above the 1.15-meter mark. There are transparent panels in front of the service judge to help determine this height. These panels have separate lines drawn depending on where the player is serving from. The service judge also checks whether the racket is pointing in a downward direction.
The service judge's role is crucial to the game, as without their call, the umpire will not know whether a service is legal or not. This can cause a delay in the game. According to the Badminton World Federation (BWF), the service judge must sit opposite the umpire so that the umpire can see them at the exact moment of service. This allows the umpire to promptly halt the game if a player commits a service fault.
The service judge is one of the technical officials appointed by the tournament referee. They are the only official seated opposite the umpire, with the space on the umpire's left and right reserved for bins where players can place their items.

Checking for service faults
The service judge in badminton sits on a low chair opposite the umpire, allowing them to be near the same height as the shuttlecock during service. They are responsible for checking if the service is legal and for communicating any service faults to the umpire. Here are some key points they need to check for service faults:
Height of the Shuttlecock
The service judge must ensure that the shuttlecock is hit below the server's waist. The whole shuttlecock should be below 1.15 meters from the surface of the court when struck by the server's racket, with the racket shaft pointing downwards. This rule helps prevent high service faults, which occur when the shuttlecock is struck above the waist of the server.
Racket Direction
The service judge must also check that the racket is pointing in a downward direction during the serve. A service fault occurs if the racket is not directed downwards, as this can affect the legality of the serve.
Server's Foot Position
The server must position their feet correctly within the service court. A foot position fault occurs if the server fails to maintain the proper foot placement during the serve. This fault results in a point loss for the serving side.
Shuttlecock Placement
The service judge must pay attention to the placement of the shuttlecock. A shuttlecock placement fault occurs when the server fails to deliver the shuttlecock correctly into the opponent's service court. This fault also results in a point loss for the serving side.
Undue Delay
Any undue delay in the service is considered a fault. This includes taking an excessively long time to serve or pausing between the backswing and forward swing of the racket. The umpire will usually provide a warning before calling a fault for undue delay.
The service judge plays a crucial role in ensuring the legality of the service and promptly communicating any faults to the umpire through hand signals. Their position opposite the umpire and at a lower height provides an optimal view for judging service faults.

Providing replacement shuttlecocks
The service judge in badminton sits on a low chair opposite the umpire. Their role is to ensure that the service is legal and to call out a player if they commit a service fault. One of their other duties is to provide a player with a replacement shuttlecock if the need arises.
Choosing the Right Shuttlecock
When choosing a shuttlecock, it is important to consider the speed, shuttle flight path quality, shuttle consistency, and durability. The speed of a shuttlecock will determine how far it travels and how quickly it decelerates. Slower shuttlecocks are better for beginners as they will travel a shorter distance, whereas faster shuttlecocks are better for more advanced players. The shuttle flight path quality refers to how closely the shuttlecock follows the ideal flight path. Shuttle consistency refers to how accurately the shuttlecock lands in the same spot when hit in the same way. Finally, shuttlecock durability refers to how long the shuttlecock will last before it needs to be replaced.
Storing Shuttlecocks
To ensure durability, shuttlecocks should be stored in a humid environment, such as above a water tray. If this is not possible, shuttlecock tubes should be sealed immediately after use and stored in a relatively low-temperature environment to prevent moisture loss.
Replacing Shuttlecocks During a Match
During a match, the service judge is responsible for providing replacement shuttlecocks to players if needed. Due to the COVID-19 pandemic, players may now use dispensers at the side of the court to retrieve new shuttlecocks and reduce contact.
Picking Up Shuttlecocks Safely
It is important to pick up shuttlecocks safely to avoid injury. Small objects like shuttlecocks can cause back injuries when bending down to pick them up. One way to safely pick up a shuttlecock is to use the "Ballerina" method, where you balance on one leg and extend the other leg horizontally behind you. Then, extend your arm to reach the shuttlecock. Another method is to "Stick your butt out," which uses your leg muscles more than your back muscles, reducing the risk of back injury.

Using hand signals
The service judge in badminton sits on a low chair opposite the umpire, allowing them to be near the same height as the shuttlecock during the service. This gives them a better view to judge whether the server has committed a fault. The service judge has two main responsibilities: calling out a player if they commit a service fault and providing a player with a replacement shuttlecock if necessary.
Since the service judge's role is to check for service faults, they need to be well-versed in badminton's service laws and the hand signals that communicate violations of each service law. Here are some of the hand signals used by the service judge to indicate service faults:
- If a player's feet are off the ground or on the boundary line during the serve, the service judge will stretch out their right leg and signal a fault with their right hand.
- When a player violates service rule 9.1.2 by stepping on the service line or outside the service court, the service judge will point to their right foot with their right hand.
- If a player violates service rule 9.1.4 by failing to hit the bottom of the shuttlecock with their racket face, the service judge will open their right hand and lightly touch the palm with their left hand.
- If a player commits an "undue delay of service" by delaying the start of the service after completing the backward movement of the racket, the service judge will communicate this fault to the umpire, who may cover their eyes with their hands to indicate uncertainty or an obstructed view.
- If a player violates service rules by hitting the shuttlecock above 1.15 meters from the surface of the court, the service judge will call a service fault and hold their hand at chest level with the palm facing down.
These hand signals are standardized and outlined in the Badminton World Federation's (BWF) Technical Official Instructions for Service Judges. It is important for players, officials, and spectators to understand these hand signals to follow the match proceedings and ensure fair play.

The service judge is responsible for calling out a player if they commit a service fault and providing a player with a replacement shuttlecock if necessary. The service judge must communicate any service fault to the umpire, who can then overrule the service judge if they choose. The service judge's main task is a short one, but without their call, the umpire will not know whether a service is legal or not, which can cause a delay in the game.
The service judge looks for two particular faults during the serve. The first is checking whether the player hits the shuttlecock above the 1.15-metre mark. There are transparent panels in front of the service judge to help them determine this height. The second fault the service judge checks for is whether the player's racket is pointing in a downwards direction.
The service judge is one of the technical officials on the badminton court. In individual singles matches, there are six officials: an umpire, a service judge, and four line judges. In doubles matches, there are eight officials, with two additional line judges.
