INMATES OF SUFFOLK COUNTY JAIL Opinion of the Court A A party seeking modification of a consent decree may meet its initial burden by showing a significant change either in factual conditions or in law. 1 Modification of a consent decree may be warranted when changed factual conditions make compliance with the decree substantially more onerous. Such a modification was approved by the District Court in this litigation in 1985 when it became apparent that plans for the new jail did not provide sufficient cell space. Inmates of Suffolk County Jail v. Kearney, Civ. Action No. 71–162–G (Mass., Apr. 11, 1985), App. 110.8 Modification is also appropriate when a decree proves to be unworkable because of unforeseen obstacles, New York State Assn. for Retarded Children, Inc. v. Carey, 706 F. 2d, at 969 (modification allowed where State could not find appropriate housing facilities for transfer patients); Philadelphia Welfare Rights Organization v. Shapp, 602 F. 2d, at 1120–1121 (modification allowed where State could not find sufficient clients to meet decree targets); or when enforcement of the decree without modification would be detrimental to the public interest, Duran v. Elrod, 760 F. 2d 756, remedying the underlying constitutional violation. Ordinarily, the parties should consent to modifying a decree to allow such changes. If a party refuses to consent and the moving party has a reasonable basis for its request, the court should modify the decree. In these cases the entire architectural program became part of the decree binding on the local authorities. Hence, any change in the program technically required a change in the decree, absent a provision in the program exempting certain changes. Such a provision was furnished by the 1985 modification of the decree. Of course, the necessity of changing a decree to allow insignificant changes could be avoided by not entering an overly detailed decree. 8 This modification was entered over the opposition of the Boston city councilors, who were parties to the litigation in the District Court.
