Illinois Appellate Court strikes down Chicago's landmarks law

Crain's Chicago Business reports:

An Illinois appellate court has struck down the city of Chicago’s landmarks ordinance, saying it is unconstitutionally vague, putting in jeopardy the city’s protection of more than 250 buildings and 50 historic districts.

The ordinance, which was enacted in 1968, prohibits any demolition or alteration of properties that are designated landmarks by the Commission on Chicago Landmarks, an eight-member body appointed by the mayor.
