Final answer:
Three Supreme Court cases pivotal to civil rights and liberties include Brown v. Board of Education which ended segregation, Miranda v. Arizona which established the 'Miranda warning', and Obergefell v. Hodges which legalized same-sex marriage nationwide.
Step-by-step explanation:
Three landmark Supreme Court cases related to civil rights and liberties include:
- Brown v. Board of Education (1954): This case tackled the issue of segregation in public schools, declaring state laws establishing separate public schools for black and white students to be unconstitutional, thus overturning the "separate but equal" doctrine of Plessy v. Ferguson.
- Miranda v. Arizona (1966): It established the importance of informing arrestees of their rights before interrogation, leading to the creation of the "Miranda warning" now common in law enforcement procedures.
- Obergefell v. Hodges (2015): This case involved the right to marriage equality. The Supreme Court held that same-sex couples have the fundamental right to marry, guaranteed by both the Due Process Clause and the Equal Protection Clause of the Fourteenth Amendment.
These cases reflect the Supreme Court's ongoing role in interpreting the Constitution to protect civil liberties, such as equality, due process, and privacy.
