New York City Housing Authority residents who went without heat during a cold snap that hit the city this past winter won’t be able to band together as a certified class in a suit against the  housing authority, a Manhattan judge said in Friday.

Manhattan Supreme Court Justice Carol Edmead also told attorneys from Willkie Farr & Gallagher and the Legal Aid Society that the state court case regarding lost heat may become pre-empted by a consent decree in a federal lawsuit against NYCHA that addresses a myriad of issues with living conditions in the city’s public housing, which awaits a judge’s approval.
