Taldur
From The Stargate Omnipedia
Literally meaning "justice," the Taldur is a judicial body on P3X-775. 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.
