In the case of brown versus board of education of topeka , how did process of judicial review allow the superior court to decide on the case

In the case of Brown v. Board of Education of Topeka, the process of judicial review allowed the Supreme Court to decide on the case by examining the constitutionality of segregation in public schools. The Court used judicial review to review the lower court's decision, which upheld the constitutionality of segregation, and ultimately declared segregation in public schools unconstitutional in violation of the Equal Protection Clause of the Fourteenth Amendment. This decision set a precedent and established the principle of "separate but equal" as inherently unequal, leading to the desegregation of public schools across the United States.
