Falcon Funding owned land in Elgin, Illinois. Elgin agreed to annex the land in 1991. The property never was developed. In 2005, Falcon asked the trial court to order the property disconnected from Elgin.
Falcon and Elgin both asked the trial court for a summary judgment. The court denied Elgin’s request, and gave Falcon summary judgment, disconnecting the property.
Elgin appealed, and raised equitable estoppel [reliance by one party — here, the city — on the word or conduct of another so that the party (city) changes his position and subsequently suffers harm] as an affirmative defense to Falcon’s request for disconnection. Falcon argued that Elgin forfeited its equitable estoppel argument because the city had not specifically stated it as an affirmative defense to the complaint. Elgin asserted the argument was not forfeited because it was raised as a defense to Falcon’s summary judgment request.
