Background information 
There remains some confusion as to whether or not this ceremony ended with the incorporation of the Federation, since Deanna Troi, referring to the ceremony, stated in "These Are The Voyages..." that "This alliance will lead to the Federation." This line is ambiguous, however, and may simply be Troi's characterization of the Federation's initial de facto, if not de jure, nature. It should be noted, however, that at no time do any of the 22nd century characters seen in "These Are the Voyages..." use the term "Federation", referring to it instead as a "coalition" or an "alliance". Furthermore, Troi's line was the only reference to the Federation in the episode's final draft script.

According to a newspaper clipping titled "It's Federation Day!" created for the Picard family album in , but not seen on-screen, the Constitution of the United Federation of Planets was formally signed in San Francisco by five dignitaries, representing Earth, Tellar, Vulcan, Andor, and Alpha Centauri, on October 11, 2161. These dignitaries were outspoken on the Earth-Romulan War. Representatives at the ceremony included:

 Ambassador Titus Oleet (Alpha Centauri Colony)
 Ambassador Natha Kell (Tellar Prime)
 Ambassador Sarahd (Andoria; later appointed Vice President)
 Ambassador T'Jan (Vulcan)
 Ambassador Thomas Vanderbilt (Earth; later appointed President)
 Major General Georges Picard

Immediately after the ceremony, the Federation Council met for the first time and elected the President and Vice-President.
