Understanding these 15 Supreme Court cases is vital for AP U.S. Government & Politics students because:
Short Summary:
In 1801, President John Adams appointed William Marbury as a justice of the peace. However, his commission was not delivered before Thomas Jefferson took office. Marbury petitioned the Supreme Court to compel Secretary of State James Madison to deliver the commission.
Constitutional Issue:
Whether the Supreme Court has the authority to declare an act of Congress unconstitutional, thereby establishing the principle of judicial review.
Holding and Constitutional Principle:
The Court, led by Chief Justice John Marshall, held that while Marbury was entitled to his commission, the Court did not have the authority to issue a writ of mandamus under the Judiciary Act of 1789. This decision established the principle of judicial review, allowing the Supreme Court to invalidate unconstitutional laws.
Impact:
Short Summary:
Maryland imposed a tax on the Second Bank of the United States. James McCulloch, a cashier at the Baltimore branch, refused to pay the tax, leading to a legal battle over the bank’s constitutionality.
Constitutional Issue:
Whether Congress has the implied power to create a national bank and whether a state can tax a federal institution.
Holding and Constitutional Principle:
The Court ruled that Congress possessed implied powers under the Necessary and Proper Clause to establish the bank. Additionally, the Supremacy Clause was invoked to declare that Maryland could not tax the federal bank, as federal laws take precedence over state laws.
Impact:
Short Summary:
Charles Schenck distributed leaflets urging resistance to the military draft during World War I. He was convicted under the Espionage Act of 1917 and appealed on First Amendment grounds.
Constitutional Issue:
Whether the Espionage Act’s restrictions on speech violated the First Amendment’s free speech protections.
Holding and Constitutional Principle:
The Supreme Court upheld Schenck’s conviction, introducing the “clear and present danger” test. The Court ruled that speech creating a clear and present danger of substantive evils could be restricted.
Impact:
Short Summary:
African American students were denied admission to public schools based on segregation laws. They challenged the “separate but equal” doctrine established by Marbury v. Madison.
Constitutional Issue:
Whether racial segregation in public schools violates the Equal Protection Clause of the Fourteenth Amendment.
Holding and Constitutional Principle:
The Court unanimously ruled that “separate educational facilities are inherently unequal,” overturning the “separate but equal” doctrine. This decision declared racial segregation in public schools unconstitutional.
Impact:
Short Summary:
The New York Board of Regents authorized a voluntary, non-denominational prayer to be recited in public schools. Several organizations filed suit, arguing it violated the Establishment Clause of the First Amendment.
Constitutional Issue:
Whether the state-sanctioned prayer in public schools violates the Establishment Clause of the First Amendment.
Holding and Constitutional Principle:
The Supreme Court held that state-sponsored prayer in public schools is unconstitutional, even if it is voluntary and non-denominational. The decision reinforced the separation of church and state.
Impact:
Short Summary:
Charles Baker and other Tennessee residents challenged the state’s apportionment of legislative districts, arguing that unequal representation violated the Equal Protection Clause.
Constitutional Issue:
Whether the Supreme Court has jurisdiction to hear cases related to legislative apportionment and if unequal representation violates the Equal Protection Clause.

The Court ruled that redistricting issues present justiciable questions and do not fall outside the purview of the judiciary. This case established that courts could intervene in and decide redistricting cases.
Impact:
Short Summary:
Clarence Gideon was charged with felony theft in Florida. He requested a court-appointed attorney but was denied based on state law. Gideon filed a habeas corpus petition, arguing his Sixth Amendment rights were violated.
Constitutional Issue:
Whether the Sixth Amendment’s right to counsel applies to defendants in state courts through the Fourteenth Amendment’s Due Process Clause.
Holding and Constitutional Principle:
The Court unanimously ruled that the right to counsel is fundamental and must be provided to defendants in all felony cases, regardless of their ability to pay. This case extended the right to legal representation to state courts.
Impact:
Short Summary:
Students wore black armbands to protest the Vietnam War and were suspended by the school. They sued, claiming their First Amendment rights were violated.
Constitutional Issue:
Whether the prohibition of symbolic speech (wearing armbands) in public schools violates the First Amendment’s free speech clause.
Holding and Constitutional Principle:
The Court held that students do not “shed their constitutional rights to freedom of speech or expression at the schoolhouse gate.” The armbands were considered symbolic speech protected by the First Amendment, as they did not disrupt school operations.
Impact:
Short Summary:
The Nixon Administration attempted to prevent the New York Times from publishing the Pentagon Papers, classified documents detailing U.S. involvement in Vietnam. The administration argued that publication threatened national security.
Constitutional Issue:
Whether the government’s attempt to prevent publication (prior restraint) violated the First Amendment’s freedom of the press.
Holding and Constitutional Principle:
The Court ruled that the government could not impose prior restraint on the press unless it could prove that publication would cause a “direct, immediate, and irreparable” harm to the nation. The Pentagon Papers were allowed to be published, reinforcing press freedom.
Impact:
Short Summary:
Jonas Yoder and other Amish parents refused to send their children to school beyond the eighth grade, citing religious beliefs. They were charged under a Wisconsin law mandating high school attendance.
Constitutional Issue:
Whether the state’s mandatory high school attendance law violated the Free Exercise Clause of the First Amendment.
Holding and Constitutional Principle:
The Court held that the state’s interest in compulsory education was not sufficient to outweigh the Amish parents’ right to free exercise of religion. The decision prioritized religious freedom over educational mandates.
Impact:

Constitutional Issue:
Whether the creation of racially-based districts violates the Equal Protection Clause of the Fourteenth Amendment.
Holding and Constitutional Principle:
The Court held that redistricting based primarily on race must be held to a strict scrutiny standard. The unusual shape of the district indicated an intent to segregate voters by race, which was unconstitutional.
Impact:
Short Summary:
Alfonzo Lopez was charged with carrying a concealed handgun into his high school, violating the Gun-Free School Zones Act of 1990. He argued that the Act exceeded Congress’s authority under the Commerce Clause.
Constitutional Issue:
Whether the Gun-Free School Zones Act exceeded Congress’s power under the Commerce Clause.
Holding and Constitutional Principle:
The Court ruled that the Act was unconstitutional because carrying a gun in a school zone did not substantially affect interstate commerce. This decision marked the first time in decades that the Court limited Congress’s Commerce Clause powers.
Impact:
Short Summary:
Chicago enacted a handgun ban, which was challenged following the Supreme Court’s decision in District of Columbia v. Heller, which recognized an individual’s Second Amendment right to bear arms. The question was whether the Second Amendment applies to state and local governments.
Constitutional Issue:
Whether the Second Amendment’s right to keep and bear arms is incorporated against the states through the Fourteenth Amendment’s Due Process Clause.
Holding and Constitutional Principle:
The Court held that the Second Amendment right is fully applicable to the states, thereby invalidating Chicago’s handgun ban. This decision affirmed that fundamental rights are protected from state infringement.
Impact:

Constitutional Issue:
Whether the BCRA’s restrictions on independent political expenditures by corporations violate the First Amendment’s freedom of speech clause.
Holding and Constitutional Principle:
The Court ruled that corporate funding of independent political broadcasts in candidate elections cannot be limited under the First Amendment. This decision equated corporate spending with individual free speech rights.
Impact:
Short Summary:

Whether a woman’s right to choose to have an abortion is protected by the Constitution, and if so, to what extent.
Holding and Constitutional Principle:
The Court held that a woman’s right to privacy under the Due Process Clause of the Fourteenth Amendment extends to her decision to have an abortion. This decision effectively legalized abortion nationwide, setting a precedent for reproductive rights.
Impact:
Note: Roe v. Wade is no longer required on the AP Government exam starting in 2023, but understanding its implications remains valuable for comprehensive knowledge of U.S. legal history.
