The Kethni Council was the governing body of the planet Andoria and the myriad of Kethni that dominated Andorian society. Each Kethni sent a delegation to the Council which usually consisted of at least 300 individuals in total who later voted on matters of both state as well as legislation. The Kethni Council was also responsible for electing a President from amongst their ranks with the office carrying only a few executive powers. The Presidents role on the Council was simply presiding over meetings as well as attend to the administrative needs of the group.
In addition to this duty, the Council was also responsible for oversight of the Andorian Defense Force which was not part of Starfleet following the formation of the United Federation of Planets. Furthermore, the Kethni Council maintained its own intelligence service in the form of the Am Tal. (Decipher RPG module: Worlds)
