what was the ruling in the case of brown V Board of Education

The ruling was unanimous.

Explanation:

In “Brown v. Board of Education: Opinion of the Court,” Chief Justice Earl Warren explains the Supreme Court’s unanimous ruling in favor of the Browns, an African American family of Topeka, Kansas, against their local board of education. The Browns complained that their daughter, a third-grader, had to attend a school across town because the local school had refused her on account of her race. The board claimed it had acted in accord with the doctrine of “separate but equal” education established by the case of Plessy v. Ferguson in 1896. The Supreme Court, however, has decided to strike down Plessy v. Ferguson and declare that segregation in public schools violates the Equal Protection Clause of the Fourteenth Amendment and is therefore unconstitutional.
