Rillaan, designated P3X-775 by the Tau'ri, and called Taldor (or Taldur) occasionally by Stargate Command was a planet in the Milky Way galaxy with a Stargate. The leaders and judicial body of this planet is called the Taldor, and their laws are absolute and decisive.
Every crime, small or big, are punishable. It is, for example, forbidden to aid criminals in any way, something SG-1 discovered when helping Roshure, or to carry weapons on ancient grounds. The trials are swift and frank. The prisoners are gathered and beamed to the Tal'al, which is a large, dark room. Voices all around are telling what their crimes are and then they are sentenced.
The judicial body (Taldor) believe in zero tolerance almost religiously. They do not use death penalty as a punishment, but they do punish nearly every criminal, with no appeals process, to life imprisonment on the planet Hadante. That planet has a Stargate, but no Dial Home Device that can help the prisoners get away.
By far the most important characteristic about this planet and its judicial body is their belief in the justice, as explained above. The judicial body believes punctuality is emblematic of civilized behavior. Its members are xenophobic and, as the Tau'ri see them, even arrogant, narrow-minded and self-centered.
Contact with Earth
SG-1 came to Taldur with weapons on their ancient grounds, which was a crime by their standards. They also helped the criminal Roshure, which definitely didn't help their impression on the judicial body. After they broke out of the prison, they also took Linea with them. (SG1: "Prisoners")
