The match referee in badminton is called the umpire. There are 8 other linesmen for making line calls.

The Umpire will keep the score in a supervised game.

An Umpire is in control of a particular match, usually called a rubber, and has to know the rules of Badminton and ensure the game is played fairly within the rules. The most obvious job is to keep the score, calling it out between points so that the players and spectators know the score. The Umpire is also required to call any faults and sort any problems during the games. Umpires also act as Service Judges and work as a team with the Umpire when both are on court. The Umpire reports any problems to the Referee who has the final say at the event.
