It is however specified that the body can legislate. The exact process of legislation within the Council itself is unclear - though it is clear that Emperors have possessed the power of veto since Uriel Septim VI's reign in the early 4th century of the Third Era.
The leader at the end of the Third Era was High Chancellor Ocato, an Altmer who is said to have been virtually running the Empire for 15 years after Emperor Uriel Septim VII's murder in 3E 433. Following the Oblivion Crisis, Ocato began to recognize the threat of the Thalmor and was assassinated.
The Council convenes at its chambers in the center of the Imperial Palace complex, within the Imperial City. The Council chamber comprises a large circular table encircled by tall chairs. The table is in the exact center of a dome shaped room possessive of an extremely high ceiling. The palace is built around the ancient Ayleid White-Gold Tower stretching hundreds of feet into the air, which at least partially accounts for the design of the Council chamber.
The exact details of what makes up the council is unknown. Known members are:
- Emperor of the Empire of Tamriel
- Lord High Chancellor/Imperial Battlemage 
- Amaund Motierre
- King of Morrowind
- Counts of Cyrodiil
- Jarls of Skyrim
