What are the duties and responsibilities of referees in table tennis?

Answer 1

For each match there is an umpire, whose primary duty is to decide the result of each rally.

He is also 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.

Answer 2

The top official is the Tournament Referee.

The role of a tournament referee differs widely from one Association to another and from one tournament to another.

At one extreme he or she is involved in every part of the organisation, from drafting the entry form to arranging the finals.

At the other extreme, the referee appears only on the day of the tournament solely to decide any question of rule interpretation.

For each match there is an umpire, whose primary duty is to decide the result of each rally.

He is also 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.

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.
