This is a school desegregation case brought by black parents and their children who attend the Boston public schools. Plaintiffs seek for themselves and on behalf of their class, it is stated, declaratory and injunctive relief against the defendants for a myriad of acts that allegedly violate the constitutional rights of the plaintiff class. Defendants are the Boston School Committee, its individual members, and the Superintendent of the Boston Public Schools (collectively "the city defendants"), and the Board of Education of the Commonwealth of Massachusetts, its individual members, and the Commissioner of Education (collectively "the state defendants"). Plaintiffs have alleged that the city defendants have intentionally brought about and maintained racial segregation in the Boston public schools by various actions, including the adoption and maintenance of pupil assignment policies, the establishment and manipulation of attendance areas and district lines reflecting segregated residential patterns, the establishment of grade structures and feeder patterns, the administration of school capacity, enlargement, and construction policies, transportation practices, and by unjustifiably failing to adopt or implement policies reasonably available to eliminate racial segregation in the Boston public schools.
