As a CBA is a legally binding contract, it can be enforced only by the parties that signed it. CBAs that are incorporated into development agreements can be enforced by the government as well as by community groups. There is no case law regarding the validity and enforceability of CBAs. Donald Trump's 1993 CBA-like contract relating to the New York City Riverside South project was the subject of a 2008 New York Appellate Division opinion, but the court held that the contract's terms were expired.
