Chicago can’t bulldoze any of the 554 homes and businesses it owns in Bensenville for 30 days, a DuPage County judge ruled Monday.

The city can’t even begin preparing those properties for demolition during that time, Judge Kenneth Popejoy said, handing Chicago a setback as he granted the emergency request for a delay filed by Bensenville officials.

Chicago won a major victory last week when Popejoy agreed to lift a yearlong injunction that had blocked it from demolishing homes and businesses in the western suburb to make room for a massive, $15 billion expansion of O’Hare Airport.
