Station regulations were a set of rules aboard Deep Space 9 in the 2370s. In a Dominion simulation in 2371, Miles O'Brien was attacked by a Jem'Hadar, whom Michael Eddington let go without punishment. When Julian Bashir pointed out that station regulations prohibited such attacks, Eddington agreed but stated the Jem'Hadar were not aware of them. (DS9: "The Search, Part II") In 2373, Nog and Jake Sisko moved in together. When Nog temporarily moved out again, Captain Sisko informed his son that the size of his quarters required two or more occupants by station regulation. (DS9: "The Ascent")
