Anti-Sith bill

In the latter stages of the Old Sith Wars, the Galactic Senate of the Republic approved a bill that banned the Sith religion. The bill was proposed in response to the carnage the Sith inflicted upon the galaxy during the Jedi Civil War of 3959–3956 BBY. The legislation was approved, and banned not only the religion, but all affiliated organizations and governments, as well as the teachings of the Sith philosophy. It remained in effect from the end of the Jedi Civil War until the New Sith Wars, during which it was used as justification for the Republic's battle against the New Sith Empire and its successor organization, the Brotherhood of Darkness. It was apparently nullified sometime during the Great Peace of the Republic, as by the time of the Clone Wars, the Galactic Constitution held provisions that specifically outlawed persecution based on religious affiliation.
