The main functions of the Senate are to mediate disputes between members, provide for the common defense, create and pass laws into effect that would benefit most of the Republic, and regulate inter-system trade. The Jedi Order, although technically not officially part of the Republic, are considered the defenders of the general Republic. The Republic often orders the Jedi to specific areas that require assistance. In this way, they are eventually the unofficial police force of the Republic. They become representatives of the Senate as well, to some extent.
