A neutral planetoid used by the Federation as a conference site, to which the Enterprise-D carried the feuding Antican and Selay delegations in 2364.
Parliament is a neutral conference planetoid referred to in the first-season Next Generation episode Lonely Among Us. It is the Enterprise-D's destination throughout the story but is not itself seen.
In 2364 the Anticans and the Selay, hostile neighbours from the Beta Renner system, have both asked to join the Federation. Starfleet arranges for their differences to be worked out at Parliament and assigns the Enterprise to carry both delegations there.
The voyage is interrupted when the ship passes through an energy cloud and a life form from it takes over first Worf, then Beverly Crusher, then the ship's computer and finally Picard, who beams himself out into the cloud. Once he is recovered through the transporter the ship resumes its course for Parliament.
