A state appeals court has revived a class action lawsuit filed by residents claiming the New York City Housing Authority failed to provide heat and hot water during a long, cold winter.

The Appellate Division, First Department, panel justices unanimously reversed New York County Supreme Court Judge Carol Edmead’s dismissal of Diamond v. New York City Housing Authority. The panel in its decision Tuesday certified the class for the lawsuit and reinstated a claim for breach of the warranty of habitability.
