For months, preservationists fought to save Prentice, which was designed by celebrated architect Bertrand Goldberg, by trying to have it designated as a landmark, the Chicago Tribune reported.
The Commission on Chicago Landmarks initially said the structure is worthy of preliminary landmark designation but Thursday rescinded the decision based on an economic impact report, effectively giving the university a green light to go ahead with its building plans.
Preservationists have indicated the fight may not be over, saying Thursday's proceedings violated the ordinance under which the landmarks commission is supposed to operate.
"We asked for a day in court," said Jonathan Fine, executive director of Preservation Chicago. "Instead, we got a show trial."
