Same as the umpire in any other sport - to uphold the rules of the game.
Badminton Europe has an age limit of 55 for umpire assessment and Badminton World Federation will not assess an umpire over age 50, and they must retire at 55. Assessment is the process of becoming an accredited umpire after completing training courses. As far as how yound can an umpire be, Sandarina Lok was the youngest umpire in the Badminton Association of Malaysia when she passed the Grade 3 Umpire exam in 2010 at the age of 14. The UKs youngest umpire was 17 years old in 2012. Since he was not 18, he could not represent Great Britain and officiate court-side at the London Olympics.
An umpire is in charge of the game.
Keeps score - and enforces the rules of the game.
