The Great Hall of the Federation Council is located within the Federation Headquarters on Earth. It is one the most securiest places in the Federation. By 2401 it was guarded by Special Jem'Hadar Marine Forces. The Great Halls is the main chamber where all representives of the Federation meet to discuss any issues.
In 2401 the entire Council was assembled in the Great Halls to hear Captain Zack Marshall-Bennet and his crew discuss why they disobeyed orders and prevented the relocation of the inhabitants of Ba'ku. After the meeting all the charges against Bennet and his crew were dropped.
