Referees

[Sarah]

a group of people, sometimes known as an officiating crew, that cover sports games (such as football, basketball, hockey, and so forth [baseball's referees are known as umpires]). also known as people who should be replaced by robots on the field because of their unmistakably horrible calls on key plays and big games (see: referees overturning an interception in Colts V Steelers, 1/15/06)

Referees in Weightlifting. Three officials whose job is to ensure that the equipment and the lifts conform to the IWF rules. Each referee judges the lift independently and signals their verdict on the light signals. One of the referees takes up the position of chief referee, who gives the signal to lifters to lower the bar at the end of the lift. The chief referee sits directly in front of and not less than 6m from the lifter.
