Colonial Administration Authority

The Colonial Administration Authority, abbreviated CAA and often referred to as Colonial Administration or Colonial Authority, is an organization under the ultimate control of the Unified Earth Government. The CAA acted as a secondary governing body that helped the UEG govern the various colony worlds of humanity.

Overview
The CAA kept extensive files on every colony, world, and city under its care. The document containing these files was referred to as the CAA Factbook. These files contained everything from topographic maps to the information on the materials the city sewer system was built from. In addition, the CAA oversaw the Outer Colony vaccination program which held the largest DNA database of the human population. The CAA provided this information to ONI special weapons teams upon request. It could be very helpful when defending colonies from Covenant attack.

The CAA was also responsible for the colonization of worlds, as evident by the "CAA" hull classification symbol on their colony ships, such as the.

Over the course of the Human-Covenant War, the UNSC had largely taken over many of the responsibilities of other branches of the government. The CAA was described as "a little more resistant to the idea than the UEG and has subsequently been stripped of most of its power." It is therefore likely that the organization no longer exists in any functional capacity by 2552, though the Factbook was still being updated as late as 2550.
