The officiating committee in the game of badminton consists of an umpire, a service judge and 10 line judges. The umpire is responsible for enforcing rules of the game and may overrule decisions made by the service judge and line judges in the event of an obvious error.
The umpire is positioned in a high seat at the extended net line, enabling him to detect player faults around the net and contact faults.
The service judge sits at the side of the net opposite the umpire. A lower seat places the service judge's eyes at the waist level of the players to spot service faults effectively.
The 10 line judges surround the perimeter of the court to make in and out calls within their designated territories. Each line judge uses badminton sign language to communicate his respective ruling.
