Petitioners sought desegregation of the Park Hill area schools in Denver, and, upon securing an order of the District Court directing that relief, expanded their suit to secure desegregation of the remaining schools of the Denver school district, particularly those in the core city area. The District Court denied the further relief, holding that the deliberate racial segregation of the Park Hill Schools did not prove a like segregation policy addressed specifically to the core city schools and requiring petitioners to prove de jure segregation for each area that they sought to have desegregated. The court nevertheless found that the segregated core city schools were educationally inferior to "white" schools elsewhere in the district and ordered the respondents to provide substantially equal facilities for those schools. This latter relief was reversed by the Court of Appeals. The Supreme Court held that: (1) the District Court, for purposes of defining a "segregated" core city school, erred in not placing Negroes and Hispanos in the same category and (2) the courts below did not apply the correct legal standard in dealing with petitioners' contention that respondent School Board had the policy of deliberately segregating the core city schools.
