 Justice Thomas also rejected the view advanced by the dissent that these school districts were in danger of resegregation.He contended that whatever trends toward classroom racial imbalance have obtained, they were not the result of state-sanctioned segregation as in the pre-"Brown" era.Justice Thomas goes on to call out the dissent for adopting segregationist reasoning advanced in "Brown", particularly its insistence that the Court should defer to local school board knowledge, expertise, and judgment.
