After a judicial finding of constitutional violation, petitioners were ordered in 1973 to place pretrial detainees in single cells. In return for certain benefits, petitioners committed themselves in 1979 to continued compliance with the singlecelling requirement. They reaffirmed this promise in 1985. It was clearly not an abuse of discretion for the District Court to require petitioners to honor this commitment. I would affirm the judgment of the Court of Appeals.
