The U.S. Supreme Court has played a crucial role in shaping American law and society. Through its decisions, the Court has addressed a wide array of issues, from civil rights to the balance of powers between government branches.

World History Edu American historians present ten landmark Supreme Court cases that have significantly impacted the United States.

Marbury v. Madison (1803)

Summary: Marbury v. Madison established the principle of judicial review, allowing the Supreme Court to nullify laws that it deems unconstitutional. This case originated when William Marbury sued Secretary of State James Madison for not delivering his commission as a justice of the peace.

Impact: This decision cemented the judiciary’s role as a co-equal branch of government, capable of reviewing and invalidating legislative and executive actions that violate the Constitution. It laid the foundation for the Court’s authority and its role in maintaining the balance of power among the branches of government.

McCulloch v. Maryland (1819)

Summary: This case addressed the scope of federal power and the relationship between federal and state governments. The state of Maryland attempted to tax the Second Bank of the United States, but the bank’s cashier, James McCulloch, refused to pay the tax.

Impact: The Supreme Court, under Chief Justice John Marshall, ruled that Congress had implied powers under the Necessary and Proper Clause of the Constitution to create the bank, and that Maryland could not tax it. This case affirmed the supremacy of federal law over state law and expanded the interpretation of federal powers.

Dred Scott v. Sandford (1857)

Summary: Dred Scott, an enslaved African American, sued for his freedom on the grounds that he had lived in free territories. The Supreme Court, however, ruled that African Americans, whether enslaved or free, could not be American citizens and had no standing to sue in federal court.

Impact: This decision exacerbated national tensions over slavery and contributed to the outbreak of the Civil War. It is widely regarded as one of the worst decisions in Supreme Court history, as it denied basic human rights to African Americans and invalidated the Missouri Compromise.

Plessy v. Ferguson (1896)

Summary: Homer Plessy, who was seven-eighths white and one-eighth black, challenged Louisiana’s segregation laws by refusing to leave a whites-only railroad car. The Supreme Court upheld state segregation laws under the “separate but equal” doctrine.

Impact: This decision legitimized state-imposed racial segregation for over half a century, leading to widespread discrimination and the entrenchment of Jim Crow laws across the South. It wasn’t until the Civil Rights Movement that this doctrine was overturned.

Brown v. Board of Education (1954)

Summary: This case challenged the legality of racial segregation in public schools. The Court unanimously ruled that segregation in public education violated the Equal Protection Clause of the Fourteenth Amendment.

Impact: Brown v. Board of Education overturned Plessy v. Ferguson, declaring that “separate but equal” facilities are inherently unequal. This landmark decision was a major victory for the Civil Rights Movement and paved the way for further desegregation and the fight against racial inequality in America.

Miranda v. Arizona (1966)

Summary: Ernesto Miranda was convicted of kidnapping and rape based on his confession during police interrogation, without being informed of his rights. The Supreme Court ruled that detained criminal suspects must be informed of their rights to an attorney and against self-incrimination prior to police questioning.

Impact: This decision led to the creation of the “Miranda rights,” which must be read to suspects upon arrest. It significantly transformed law enforcement practices, ensuring that individuals are aware of their constitutional rights during the criminal justice process.

Roe v. Wade (1973)

Summary: This case centered around “Jane Roe,” a pseudonym for Norma McCorvey, who challenged Texas laws criminalizing most abortions. The Supreme Court ruled that the right to privacy under the Due Process Clause of the Fourteenth Amendment extended to a woman’s decision to have an abortion.

Impact: Roe v. Wade legalized abortion nationwide, striking down many state laws restricting it. The decision sparked ongoing debates and legal battles over reproductive rights, leading to significant political and social discourse that continues to this day.

United States v. Nixon (1974)

Summary: During the Watergate scandal, President Richard Nixon claimed executive privilege to avoid releasing taped conversations. The Supreme Court unanimously ruled that the president must comply with a subpoena for the tapes.

Impact: This decision reinforced the principle that no one, not even the President of the United States, is above the law. It led to Nixon’s resignation and strengthened the checks and balances within the federal government, ensuring that executive privilege cannot be used to obstruct justice.

 

Bush v. Gore (2000)

Summary: The 2000 presidential election between George W. Bush and Al Gore hinged on the recounting of votes in Florida. The Supreme Court halted the recount, effectively awarding the presidency to Bush.

Impact: This controversial decision underscored the influence of the judiciary in electoral processes and highlighted issues with the U.S. voting system. It emphasized the importance of clear and fair electoral procedures and sparked debates about judicial intervention in political matters.

Obergefell v. Hodges (2015)

Summary: This case consolidated several challenges to state bans on same-sex marriage. The Supreme Court ruled that same-sex marriage is a fundamental right guaranteed by the Due Process Clause and the Equal Protection Clause of the Fourteenth Amendment.

Impact: Obergefell v. Hodges legalized same-sex marriage across the United States, marking a historic victory for LGBTQ+ rights. It affirmed the principle of equality under the law and expanded civil rights protections to include marriage equality.

14 Major Events of the Civil Rights Movement

Detailed Examination of Each Case

Marbury v. Madison (1803)

Context: The case arose from a political struggle between the outgoing Federalist administration of John Adams and the incoming Democratic-Republican administration of Thomas Jefferson. Adams had appointed several justices of the peace in the final hours of his presidency, but some commissions, including Marbury’s, were not delivered before Jefferson took office.

Decision and Reasoning: Chief Justice John Marshall wrote the unanimous opinion, stating that while Marbury was entitled to his commission, the Court could not grant it because the section of the Judiciary Act of 1789 that gave the Court the power to issue writs of mandamus was unconstitutional. This established the principle of judicial review.

Long-term Effects: Marbury v. Madison fundamentally shaped the American legal system by affirming the judiciary’s role in interpreting the Constitution. It has been cited in numerous cases to support the Court’s authority to review and overturn government actions that violate the Constitution.

McCulloch v. Maryland (1819)

Context: The state of Maryland imposed a tax on all notes of banks not chartered in Maryland, which included the Second Bank of the United States. James McCulloch, the bank’s cashier, refused to pay the tax, leading to the lawsuit.

Decision and Reasoning: Chief Justice Marshall’s opinion emphasized the Constitution’s “Necessary and Proper” Clause, allowing Congress to take actions not explicitly outlined in the Constitution if they are necessary to carry out its enumerated powers. The ruling also reinforced federal supremacy over states.

Long-term Effects: McCulloch v. Maryland has been pivotal in expanding federal power and ensuring a unified national economic policy. It has influenced subsequent rulings on federal authority and state interactions.

Brown v. Board of Education (1954)

Context: Several African American families challenged state laws establishing separate public schools for black and white students. Thurgood Marshall, representing the plaintiffs, argued that segregation harmed black children psychologically and violated the Equal Protection Clause.

Long-term Effects: The creation of “Miranda rights” transformed police procedures and reinforced the importance of constitutional protections during criminal investigations. It remains a cornerstone of criminal justice reform.

Roe v. Wade (1973)

Context: “Jane Roe,” a pseudonym for Norma McCorvey, challenged Texas laws that criminalized most abortions. The case addressed the extent of a woman’s right to privacy and bodily autonomy.
