Unified Earth Government

The Unified Earth Government (UEG) is the central civilian government that administers Earth and its colonies throughout a portion of the Orion Arm of the Milky Way galaxy. It encompasses the Colonial Administration Authority (CAA) and the United Nations Space Command (UNSC).

During the Human-Covenant War, the UNSC took authority over the UEG, leaving the UEG to focus on Earth affairs and the CAA to focus on colonial affairs while the UNSC fought the Covenant.

Government and Politics
The Unified Earth Government functions as a representative democracy and is headed by a President. The government maintains executive, legislative, and judicial branches. The Unified Earth Government Senate serves as the legislative branch of the government. A number of other executive offices are known to exist, among them the Minister of Information, the Secretary of Defense, and the Minister for the Colonies; the last position is part of the CAA. Inferring from the first and last positions, the UEG would appear to be based around a parliamentary system. Other executive ministries include the Department of the Treasury, under which operates the Internal Revenue Service. The Inner Territories Transportation Administration is an agency of the UEG that has authority over the security of public interstellar or interplanetary travel among the Inner Colonies.

While the UEG is formally a union of independently governed worlds, Earth is in a privileged position over the colonies in the election process, which has been a source of discord with some colonials. Some colonies are managed by planetary governors that lead a world's parliamentary government.

The Colonial Administration Authority is the government branch that administers the various colonies that belong to the UEG. It keeps extensive files on every colony world and city under the UEG, available to UNSC members for planning missions.
