In Sheff v. O'Neill, 238 Conn. 1, 678 A.2d 1267 (1996), the Court held that the legislature was required to remedy both de jure and de facto segregation in public schools. Id., 29-30. The court did not intend to allow state constitutional challenges on the basis of disparate impact, and it ruled as it did because it relied in part on the "independent constitutional significance" of the word "segregation" in article first, 20, of our state constitution and the affirmative constitutional obligation to provide a substantially equal educational opportunity under article eighth, 1. Id., 25-30.
