Tribunal

The Tribunal of the United Empire of Earth is an judiciary and former executive organ. It seems to be standing committee which is able to depose the Imperator of the UEE. The Tribunal consists of the current holders of the following offices: High-Advocate, High-Admiral and High-Secretary.

Tribunal of the United Planets of Earth
There are currently only a few facts known. It was the successor of the Council of the United Nations of Earth and was possibly created as a result of the transformation of the UNE into the United Planets of Earth (2523). Another organ was the Congress of the UPE, which could have been the legislative organ while the Tribunal was an executive organ.

Triumvirate
Since it's was also also called Triumvirate ("Rule of Three") it must be connected with a lot of executive power. The Triumvirate only reigned 13 years. In 2546, High-General Ivar Messer appointed himself Prime Citizen. Not one year later, he eliminated the last leftovers of democracy - if the UPE was ever an democracy - and transformed it into an hereditary monarchy titulating himself Imperator of his new found United Empire of Earth.

New Tribunal
In the following institutional conflict the Tribunal lost its ability to depose the Imperator. It regained this ability in the transition process under Erin Toi in 2792.
