What is the role of match umpire in table tennis?

Answer 1

The primary duty of the match umpire is to decide the result of each rally.

In principle, the umpire has no discretionary powers, but he is required to exercise judgment in applying some laws and regulations, such as deciding whether a rally should be a let because a player's service or return may have been affected by circumstances outside the player's control, or whether a player's behaviour is acceptable.

Where the umpire is officiating alone, his is the final decision on all questions of fact that arise during a match, including decisions on all edge balls and on all aspects of service.

In these circumstances he is directly responsible also for timing the duration of play, but when the expedite system is in operation he is assisted by another official who acts as stroke counter.
