Question

Which of the following cases ruled that segregation laws were acceptable and was later overturned through court decisions and legislation?

Answer 1

The correct answer is: "Plessy v. Ferguson (1896)"

The Plessy v. Ferguson case was about the constitutionality of the "separate but equal" principle. The decision reached allowed the proliferation of segregated schools under the belief that, if facilities were equal in quality, such education system was not violating the equality of rights provision that had been guaranteed for all US citizens by the Reconstruction Amendments to the US Constitution.  

Brown v. Board of Education subsequently overturned the abovementioned previous Supreme Court decision in 1954 and declared segregation unconstitutional claming that, in practice, it actually deprived black students. The court published a deadline and all public schools nationwide had to abolish such practice and to adopt racial integration.
