The Supreme Court of the United States plays a crucial role in interpreting the Constitution and shaping American law. Through landmark rulings, the Court has defined civil rights, limited government power, and influenced social policy. Below are some of the most important Supreme Court decisions in U.S. history.
1. Marbury v. Madison (1803)
In Marbury v. Madison, the Court established the principle of judicial review, giving it the authority to declare laws unconstitutional. This decision strengthened the judiciary as an equal branch of government and remains a cornerstone of constitutional law.
2. Brown v. Board of Education (1954)
Brown v. Board of Education declared racial segregation in public schools unconstitutional. The ruling overturned the “separate but equal” doctrine established by Plessy v. Ferguson and became a major catalyst for the Civil Rights Movement.
3. Miranda v. Arizona (1966)
In Miranda v. Arizona, the Court ruled that criminal suspects must be informed of their rights before police questioning. These protections—known as “Miranda rights”—include the right to remain silent and the right to an attorney.
4. Roe v. Wade (1973)
Roe v. Wade recognized a constitutional right to abortion under the right to privacy. For nearly 50 years, it shaped reproductive rights law in the United States before being overturned in 2022.
5. United States v. Nixon (1974)
In United States v. Nixon, the Court ruled that President Richard Nixon had to turn over tape recordings related to the Watergate investigation. The decision reinforced the principle that no person—not even the president—is above the law.
6. Obergefell v. Hodges (2015)
Obergefell v. Hodges legalized same-sex marriage nationwide, holding that the Constitution guarantees the right to marry regardless of sexual orientation. The decision marked a historic moment in civil rights law.
7. Dobbs v. Jackson Women’s Health Organization (2022)
In Dobbs v. Jackson Women’s Health Organization, the Court overturned Roe v. Wade, ruling that the Constitution does not confer a right to abortion and returning regulatory authority to the states. This decision significantly reshaped abortion laws across the country.
