Ultraviolet-rated constable, together with its counterpart violet-rated constable, represented one of the two highest echelons of officers leading the Sullustan Constable Brigade. This Brigade served as the law enforcement agency for the SoroSuub Corporation, the governing body of the Outer Rim Territories planet Sullust; each of its nine ranks, including ultraviolet-rated constable, derived its name from a color found within the light spectrum.
The title of ultraviolet-rated constable initially appeared in the Strongholds of Resistance sourcebook for Star Wars Roleplaying, released in 2015 by Fantasy Flight Games. This sourcebook formed part of the Star Wars: Age of Rebellion roleplaying game.
