Telettoh's Maxim was a doctrine that was adopted by many starship crew in the Galactic Republic following the Jedi Civil War. It stated that starships should not take any Sith Lords aboard due to their perceived destructive tendencies. The doctrine was first coined by the Republic Navy Admiral Telettoh who had unknowingly carried the future Sith Lord Darth Malak aboard his Hammerhead-class cruiser Testament. At that time, Malak was a member of a Jedi faction known as the Revanchists who advocated a hardline stance against the Mandalorian Neo-Crusaders. Telettoh would spend the rest of his career trying to undo the damage caused by his actions.
