Referees are the most important official and ensure the tournament is conducted fairly
Badminton is a fast-paced sport that requires several officials to ensure a fair game. Referees are the most important officials in a badminton game as they are in overall charge of the tournament or championship. They uphold the Laws of Badminton and Competition Regulations in the BWF Statutes. Referees are supported by other officials, including the umpire, service judge, and line judges, each with specific duties to ensure the tournament is conducted fairly.
The umpire is often referred to as the 'main judge' and has the authority to overrule the decisions of other officials. They are responsible for the smooth conduct of the game, ensuring players do not delay gameplay. The umpire also approves requests for shuttle changes and looks out for faults, such as a player touching the net or the shuttle touching a player's body or attire. Dressed in black, the umpire sits in a high chair overlooking the court and its immediate surroundings.
Service judges work alongside the umpire, sitting opposite them on a regular chair. They are responsible for calling service faults and providing new shuttles to the players. Service judges are qualified umpires and often rotate roles with the umpires during a tournament.
Line judges are positioned beside the badminton court, right in front of the in/out lines, to determine whether the shuttlecock lands inside or outside the boundaries. Their calls are often subjective and can be controversial. At the highest level of tournaments, such as the SuperSeries and Olympics, there are 12 line judges to ensure accurate decision-making.
While referees are the primary authority figures, the contributions of umpires, service judges, and line judges are crucial to the smooth and fair conduct of badminton tournaments. Each official plays a unique role in upholding the rules and ensuring the integrity of the sport.

Umpires are in charge of the court and make sure the match is fair
Badminton officials include referees, umpires, service judges, and line judges. Each official has distinct responsibilities to ensure the match is fair and adheres to the rules.
Umpires are the 'main judges' in badminton games. They are in charge of the court and its immediate surroundings, ensuring the game runs smoothly and preventing players from delaying gameplay. Umpires are responsible for tracking the score and calling faults, such as a shuttle touching a player or the receiver moving prematurely. They also communicate with the players and have the authority to approve requests, such as changing the shuttle. Additionally, umpires oversee faults around the net, including instances of players touching the net or the shuttle touching players' bodies or attire.
Umpires are dressed in black and typically occupy a raised chair overlooking the court. They have the power to overrule decisions made by other judges, such as the service judge or line judges. Their role is crucial to maintaining fairness and addressing any issues that may arise during the game.
At lower-level tournaments, an umpire may also assume the responsibilities of a line judge, including indicating whether the shuttlecock landed 'in' or 'out' on the lines they are overseeing.

Service judges check serves and hand out shuttlecocks
Service judges are responsible for calling service faults and providing new shuttlecocks to the players. They sit opposite the umpire on a normal chair so that the umpire can focus on the receiver. Service judges are qualified umpires and wear a black uniform. They are also in charge of calling service faults, so the umpire can focus on the receiver.
The service judge plays an important role in ensuring that the game is played fairly and according to the rules. A legal serve in badminton must be hit diagonally over the net and across the court. It must be hit underarm and below the server's waist height. The whole of the shuttle should be below 1.15 metres from the surface of the court when hit by the server, with the racquet shaft pointing downwards. The shuttlecock is not allowed to bounce.
After a point is won, the players move to the opposite serving stations for the next point. A point is scored when the shuttlecock lands inside the opponent's court. If a returned shuttlecock hits the net or lands outside the court, the player loses the point.
Service judges work alongside other officials such as the referee, umpire, and line judges to ensure the smooth and fair running of a badminton match.

Line judges indicate whether shuttlecocks land 'in' or 'out'
Line judges play a crucial role in ensuring the fairness and accuracy of badminton matches. They are responsible for determining whether the shuttlecock lands inside or outside the boundaries of the court, making subjective calls that are sometimes controversial.
In a badminton match, line judges are positioned beside the court, directly in front of the in/out lines. Their primary duty is to indicate whether the shuttlecock, or shuttle, has landed "in" or "out" on the lines. This is especially important as a point is scored when the shuttlecock lands inside the opponent's court, and the rules allow players to return the shuttlecock from both inside and outside the court.
The role of line judges becomes even more critical when considering the pace and dynamics of the game. Badminton is a fast-paced racket sport, and the ability to hit the shuttlecock over the net and into the opponent's court is fundamental. The line judges' quick and accurate judgments ensure that players' shots are fairly assessed, contributing to the overall fairness of the game.
At the highest level tournaments, such as the SuperSeries and Olympics, there can be up to 12 line judges to cover all the lines of the court. However, at lower-level tournaments, the number of officials may be reduced, and an official may take on multiple roles. For example, at national-level events, an umpire or service judge may also act as a line judge for the lines closest to them.
The role of line judges in badminton is essential to maintaining the integrity of the game. Their judgments on whether the shuttlecock lands in or out can directly impact the outcome of a match, reinforcing the importance of accurate and impartial officiating.

Technical officials handle tournament organisation and supervise other officials
Technical officials are responsible for tournament organisation and the supervision of other officials. They ensure that badminton matches are fair and proceed according to the rules.
The technical officials include referees, who are in overall charge of a tournament or championship, upholding the Laws of Badminton and Competition Regulations in the BWF Statutes. Referees are supported by umpires, who are the 'main judges' of badminton games. Umpires keep track of the score, call faults, and communicate with players. They also have the power to overrule any decisions made by service judges or line judges. Service judges, who are qualified umpires, call service faults and provide shuttles to players. Line judges sit beside the badminton court to determine whether the shuttlecock is inside or outside the boundaries. They indicate whether the shuttlecock landed 'in' or 'out' and their calls are often very subjective and controversial.
At the top tournaments, such as SuperSeries and the Olympics, there will be multiple deputy referees, a service judge, 12 line judges, and two mopper line judges. At national-level events, officials may take on multiple roles, such as the umpire or service judge acting as line judges.
