The Supreme Court of the United States (SCOTUS) stands as the pinnacle of the federal judiciary, wielding ultimate appellate jurisdiction over all federal court cases and certain state court cases involving U.S. constitutional or federal law. Established to ensure the rule of law and uphold the Constitution, the Court has the power to interpret laws and their alignment with constitutional principles. A landmark moment in its history occurred in 1803 with the case of Marbury v. Madison, where the Court asserted its authority of judicial review, enabling it to invalidate legislation that conflicts with the Constitution. This power has allowed the Court to play a critical role in shaping American law and governance. Throughout its history, the Supreme Court has addressed pivotal issues, including civil rights, federalism, and the balance of powers among branches of government. Notable decisions such as 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, have had profound impacts on American society. The Court's interpretations and rulings continue to influence legal precedents and public policy, making it a cornerstone of American democracy and a guardian of constitutional rights. Its legacy is marked by ongoing debates about judicial activism versus restraint, reflecting the evolving nature of law in response to societal changes.
