After the Supreme Court in Milliken V. Bradley determined that an interdistrict remedy for de jure segregation in the Detroit school system exceeded the constitutional violation, and remanded the case for formulation of a decree, the District Court promptly ordered submission of desegregation plans limited to the Detroit school system. After extensive hearings the court included in its decree a plan for student assignment and education components. The court determined that these components were necessary to carry out desegregation. The Court of Appeals affirmed the District Court's order concerning the implementation of and cost sharing for the four educational components. The Supreme Court held that: (1) as part of a desegregation decree a district court can order compensatory education programs for children who have been subjected to past acts of de jure segregation, (2) in designing and implementing the decrees, the courts are to focus on the nature and the scope of the violation and the decrees must be remedial, and (3) the requirement that the defendants pay one half of the additional costs attributable to the four components does not violate the 11th Amendment.
