Ap Gov Required Court Cases 2025

Navigating the intricate landscape of United States government and law requires a solid understanding of landmark Supreme Court cases. For those diving into AP Government in 2025, familiarizing yourself with the required court cases is essential. These cases, selected for their profound impact on American society, offer a lens through which to examine core constitutional principles and the ongoing evolution of legal interpretation.

Foundational Cases: Establishing Judicial Review and Federal Power

Before delving into specific cases, it’s important to grasp the bedrock principles that underpin the Supreme Court's role. Two cases, in particular, stand out:

Marbury v. Madison (1803)

• The Core Issue: The appointment of William Marbury as a Justice of the Peace was blocked by the new Secretary of State, James Madison. Marbury petitioned the Supreme Court for a writ of mandamus, forcing Madison to deliver his commission.
• The Ruling: Chief Justice John Marshall ruled that while Marbury was entitled to his commission, the section of the Judiciary Act of 1789 that allowed the Supreme Court to hear the case in its original jurisdiction was unconstitutional.
• The Impact: This case established the principle of judicial review, the power of the Supreme Court to declare laws unconstitutional. This single ruling transformed the Court into a co-equal branch of government, significantly shaping the balance of power in the American system.

McCulloch v. Maryland (1819)

• The Core Issue: The state of Maryland attempted to tax the Second Bank of the United States, a national bank chartered by Congress. The question was whether Congress had the power to establish a national bank and whether a state could tax a federal entity.
• The Ruling: The Supreme Court, again under Chief Justice Marshall, upheld the constitutionality of the national bank, citing the Necessary and Proper Clause (Article I, Section 8). The Court also ruled that states could not tax the federal government, invoking the Supremacy Clause (Article VI).
• The Impact: McCulloch v. Maryland solidified the concept of implied powers, allowing Congress to enact laws "necessary and proper" to carry out its enumerated powers. It also reinforced the supremacy of federal law over state law when the two conflict, strengthening the power of the federal government.

Cases Concerning Individual Rights and Liberties

The Bill of Rights guarantees fundamental freedoms to all Americans. The following cases illustrate the Supreme Court's role in interpreting and protecting these rights:

Schenck v. United States (1919)

• The Core Issue: Charles Schenck distributed leaflets urging men to resist the draft during World War I. He was convicted of violating the Espionage Act. The question was whether Schenck's speech was protected by the First Amendment.
• The Ruling: The Supreme Court upheld Schenck's conviction, establishing the clear and present danger test. Justice Oliver Wendell Holmes Jr. argued that speech that poses an immediate threat to public safety is not protected by the First Amendment.
• The Impact: This case set a precedent for limiting free speech during times of national crisis. While the "clear and present danger" test has been refined over time, it remains a significant landmark in First Amendment jurisprudence.

Tinker v. Des Moines Independent Community School District (1969)

• The Core Issue: Students John Tinker, Mary Beth Tinker, and Christopher Eckhardt were suspended for wearing black armbands to school to protest the Vietnam War. The school argued that the armbands disrupted the learning environment.
• The Ruling: The Supreme Court sided with the students, ruling that their symbolic speech was protected by the First Amendment. The Court stated that students do not shed their constitutional rights at the schoolhouse gate, and that their expression could only be restricted if it substantially disrupted school activities or invaded the rights of others.
• The Impact: Tinker v. Des Moines established the principle that students have a right to express their views, even if those views are unpopular, as long as the expression does not disrupt the educational environment. It has been a cornerstone case in protecting student free speech rights.

Engel v. Vitale (1962)

• The Core Issue: The New York State Board of Regents authorized a voluntary prayer to be recited in public schools. Parents challenged the prayer as a violation of the Establishment Clause of the First Amendment.
• The Ruling: The Supreme Court ruled that the school-sponsored prayer was unconstitutional. The Court reasoned that even a non-denominational, voluntary prayer violated the Establishment Clause, which prohibits government endorsement of religion.
• The Impact: Engel v. Vitale reinforced the separation of church and state in public schools, setting a precedent for subsequent cases involving religion in education.

Wisconsin v. Yoder (1972)

• The Core Issue: Amish parents Jonas Yoder, Wallace Miller, and Adin Yutzy were prosecuted for violating a Wisconsin law requiring children to attend school until age 16. The parents argued that high school attendance violated their religious beliefs.
• The Ruling: The Supreme Court sided with the Amish parents, holding that the state's compulsory education law violated their right to freedom of religion under the First Amendment. The Court recognized the long-standing traditions and values of the Amish community and concluded that requiring them to attend high school would undermine their way of life.
• The Impact: Wisconsin v. Yoder established a strong precedent for protecting religious freedom, even when it conflicts with state laws. It highlights the importance of balancing individual rights with the state's interest in education.

Gideon v. Wainwright (1963)

• The Core Issue: Clarence Earl Gideon was charged with a felony in Florida but was denied a court-appointed attorney because he could not afford one. He was convicted and sentenced to prison. Gideon argued that his Sixth Amendment right to counsel had been violated.
• The Ruling: The Supreme Court unanimously ruled in Gideon's favor, holding that the Sixth Amendment guarantees the right to counsel to all defendants in criminal cases, regardless of their ability to pay.
• The Impact: Gideon v. Wainwright revolutionized the American justice system, ensuring that all defendants, rich or poor, have access to legal representation. It led to the creation of public defender systems across the country.

Roe v. Wade (1973)

• The Core Issue: Norma McCorvey (Jane Roe) challenged a Texas law that prohibited abortion except to save a woman's life. She argued that the law violated her constitutional right to privacy.
• The Ruling: The Supreme Court ruled that a woman has a constitutional right to an abortion, based on the right to privacy implied in the Fourteenth Amendment. The Court established a trimester framework, granting states more regulatory power over abortion as the pregnancy progressed.
• The Impact: Roe v. Wade had a profound impact on reproductive rights in the United States. It legalized abortion nationwide, although the ruling has been consistently challenged and modified by subsequent cases. This ruling was overturned in 2022 by Dobbs v. Jackson Women's Health Organization, leaving abortion regulation to individual states. Although no longer good law, its historical significance makes it essential knowledge for understanding US legal history.

McDonald v. City of Chicago (2010)

• The Core Issue: Several residents of Chicago challenged the city's handgun ban, arguing that it violated their Second Amendment right to bear arms. The question was whether the Second Amendment applied to state and local governments.
• The Ruling: The Supreme Court ruled that the Second Amendment applies to the states through the Fourteenth Amendment's Due Process Clause. The Court struck down Chicago's handgun ban, affirming an individual's right to own a handgun for self-defense in their home.
• The Impact: McDonald v. City of Chicago extended the reach of the Second Amendment, limiting the ability of state and local governments to regulate firearms.

Cases Concerning Equal Protection and Discrimination

The Fourteenth Amendment guarantees equal protection under the law. These cases demonstrate the Supreme Court's efforts to ensure equality and address discrimination:

Brown v. Board of Education (1954)

• The Core Issue: Linda Brown, an African American student, was denied admission to a white-only school in Topeka, Kansas. The case challenged the "separate but equal" doctrine established in Plessy v. Ferguson (1896).
• The Ruling: The Supreme Court unanimously ruled that state-sponsored segregation in public schools was unconstitutional, violating the Equal Protection Clause of the Fourteenth Amendment. The Court declared that "separate educational facilities are inherently unequal."
• The Impact: Brown v. Board of Education overturned Plessy v. Ferguson and paved the way for desegregation of schools and other public facilities. It was a landmark victory for the Civil Rights Movement.

Shaw v. Reno (1993)

• The Core Issue: North Carolina created a congressional district that was highly irregular in shape, allegedly to create a majority-minority district. White voters challenged the district, arguing that it was an unconstitutional racial gerrymander.
• The Ruling: The Supreme Court ruled that the district was unconstitutional because it was so bizarrely shaped that it could only be explained as an effort to separate voters based on race. The Court held that while states can consider race when drawing district lines to comply with the Voting Rights Act, they cannot create districts that are so extremely irregular that they are "unexplainable on grounds other than race."
• The Impact: Shaw v. Reno limited the use of race in drawing congressional districts, requiring states to justify the shape of districts based on factors other than race.

United States v. Windsor (2013)

• The Core Issue: Edith Windsor was forced to pay estate taxes on her deceased wife's estate because the federal government did not recognize same-sex marriages under the Defense of Marriage Act (DOMA). Windsor challenged the constitutionality of DOMA.
• The Ruling: The Supreme Court ruled that DOMA was unconstitutional, violating the Equal Protection Clause of the Fifth Amendment. The Court held that DOMA's discrimination against same-sex couples was motivated by animus and served no legitimate purpose.
• The Impact: United States v. Windsor paved the way for nationwide marriage equality by undermining the legal basis for denying federal benefits to same-sex couples.

Cases Concerning the Structure of Government

These cases delve into the relationship between the branches of government and the balance of power within the federal system.

Baker v. Carr (1962)

• The Core Issue: Charles Baker challenged Tennessee's apportionment of its state legislature, arguing that the districts were drawn in such a way that voters in rural areas had disproportionately more representation than voters in urban areas. The state argued that apportionment was a "political question" that the courts should not address.
• The Ruling: The Supreme Court ruled that apportionment was not a "political question" and that the courts could hear cases challenging the fairness of legislative districts. The Court established the principle of "one person, one vote," requiring that legislative districts be roughly equal in population.
• The Impact: Baker v. Carr led to a redrawing of legislative districts across the country, ensuring that all voters have equal representation. It significantly impacted the balance of power between rural and urban areas.

Shaw v. Reno (1993) (Also relevant in Equal Protection)

• The Core Issue: North Carolina created a congressional district that was highly irregular in shape, allegedly to create a majority-minority district. White voters challenged the district, arguing that it was an unconstitutional racial gerrymander.
• The Ruling: The Supreme Court ruled that the district was unconstitutional because it was so bizarrely shaped that it could only be explained as an effort to separate voters based on race. The Court held that while states can consider race when drawing district lines to comply with the Voting Rights Act, they cannot create districts that are so extremely irregular that they are "unexplainable on grounds other than race."
• The Impact: Shaw v. Reno limited the use of race in drawing congressional districts, requiring states to justify the shape of districts based on factors other than race.

Citizens United v. Federal Election Commission (2010)

• The Core Issue: Citizens United, a conservative non-profit organization, challenged the constitutionality of the Bipartisan Campaign Reform Act (BCRA), which restricted corporate and union spending on political advertisements.
• The Ruling: The Supreme Court ruled that corporations and unions have the same First Amendment rights as individuals, and that the government cannot restrict their independent political spending. The Court overturned portions of BCRA that prohibited corporations and unions from using their general treasury funds to finance electioneering communications.
• The Impact: Citizens United v. FEC dramatically changed campaign finance law in the United States. It led to a surge in independent political spending by corporations and unions, and it has been criticized for giving wealthy interests an outsized influence in elections.

Contemporary Cases and Evolving Jurisprudence

The law is not static. The Supreme Court continues to shape constitutional law through its decisions in contemporary cases.

Obergefell v. Hodges (2015)

• The Core Issue: Several same-sex couples challenged state laws that prohibited them from marrying or refused to recognize their marriages performed in other states.
• The Ruling: The Supreme Court ruled that the right to marry is a fundamental right guaranteed to same-sex couples by both the Due Process Clause and the Equal Protection Clause of the Fourteenth Amendment. The Court held that states must allow same-sex couples to marry and must recognize same-sex marriages performed in other states.
• The Impact: Obergefell v. Hodges legalized same-sex marriage nationwide, marking a historic victory for the LGBTQ+ rights movement.

Dobbs v. Jackson Women's Health Organization (2022)

• The Core Issue: Mississippi law banned abortions after 15 weeks of pregnancy. Jackson Women's Health Organization, the only licensed abortion facility in Mississippi, challenged the law, arguing that it violated the constitutional right to abortion established in Roe v. Wade and Planned Parenthood v. Casey.
• The Ruling: The Supreme Court overruled Roe v. Wade and Planned Parenthood v. Casey, holding that the Constitution does not confer a right to abortion. The Court held that the authority to regulate abortion is returned to the states.
• The Impact: Dobbs v. Jackson Women's Health Organization eliminated the federal constitutional right to abortion, allowing states to ban or severely restrict abortion. The decision has had a profound impact on reproductive rights in the United States, with many states enacting abortion bans or restrictions.
