Landmark Supreme Court cases are significant legal decisions made by the U.S. Supreme Court that have a lasting impact on American law and society. These cases often address fundamental issues such as civil rights, individual freedoms, and the balance of power among government branches. Examples include Brown v. Board of Education, which declared racial segregation in public schools unconstitutional, and Roe v. Wade, which recognized a woman's right to choose an abortion. These cases set important legal precedents that guide future court decisions and influence legislation. They reflect the evolving interpretation of the U.S. Constitution and help shape the rights and responsibilities of individuals and government entities. Landmark cases often spark public debate and can lead to significant social change.
