The decision, or holding, in a Supreme Court case sets what is called a precedent. Precedents are treated as laws and they set standards for future cases or legal issues related to the same topic. For example, the holding in Brown v. Board of Education was that segregation in schools violated people’s legally protected equal rights. The precedent set would disallow laws that segregate based on race in schools or in the greater society. Explain the precedent set by Mapp v. Ohio based on the decision summarized above.
