Table Tennis has an umpire, an assistant umpire, a timekeeper and a stroke counter.
The assistant umpire often also acts as the timekeeper and stroke counter.
For each match there is an umpire, whose primary duty is to decide the result of each
rally. 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.
An assistant umpire is solely responsible for decisions on edge balls at the side of the table nearest to him, and he has the same power as the umpire to decide the legality of a player's service action, whether a player obstructs the ball and some of the conditions for a let.
The timekeeper is required to monitor the duration of practice, of play in a game, of intervals between games and of any authorised suspension of play, and his decision is final on the time that has elapsed.
Stroke counting is required when the expedite system is in operation and the stroke
counter's duty is solely to count the return strokes of the receiver and his decision on
this question of fact cannot be overruled.
