Taldur
From The Stargate Omnipedia
Literally meaning "justice," the Taldur is a judicial body on the world of the same name. They are strict to their rules, believing, almost religiously, that the law is absolute. One is found guilty even if one inadvertently helped a guilty criminal.
Punishment by the Taldur is permanent imprisonment on Hadante.
