Quorum of Ships' Captains
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
The Quorum of Ships' Captains is the legislative body that replaces the Quorum of Twelve after the events of Gaeta's Mutiny.
Instead of reforming the colony-based Quorum with new representatives, Lee Adama proposes that the Colonials are no longer defined by their home colonies but rather the respective ships they live on. President Roslin supports the idea and tasks Lee with restructuring the civilian government accordingly (No Exit).
In "Someone to Watch Over Me", its revealed that a new Quorum is being formed, but this time made up of ship's captains. It is unknown how many captains are on this new Quorum, but a Cylon representative, a Six named Sonja, has also been elected to this Quorum to represent the Rebel Basestar.
