Required cases at a glance
All fourteen cases required by the course. For SCOTUS Comparison, know four things for each required case: the constitutional basis, essential facts, holding, and a useful comparison point. Several of these cases involve current-doctrine developments that go beyond the original holding; those developments are covered in the chapter where each case was first introduced.
| Required case | Constitutional basis | Essential facts | Holding / reasoning | Best comparison hook |
|---|---|---|---|---|
| Marbury v. Madison (1803) | Article III; judicial review | Marbury sought a commission; the Judiciary Act purported to give the Supreme Court original jurisdiction beyond Article III | The Court could not issue the writ under the unconstitutional jurisdictional grant; the decision established judicial review of federal law | Compare whenever the supplied case concerns the Court’s authority to invalidate governmental action or the judiciary’s place in separation of powers |
| McCulloch v. Maryland (1819) | Necessary and Proper; Supremacy | Congress created a national bank; Maryland taxed the bank | Congress has implied powers to choose appropriate means for enumerated powers, and a state may not tax a valid federal instrument in a way that controls or burdens it | Compare national implied power, federalism, state interference, or the scope of congressional authority |
| Schenck v. United States (1919) | First Amendment speech | Schenck distributed anti-draft material during World War I and was convicted under the Espionage Act | The Court upheld the conviction using the historical clear-and-present-danger approach; that standard is historical AP content, not the current incitement test | Compare government limits on speech, wartime context, or how later doctrine gives speech stronger protection |
| Brown v. Board of Education (1954) | Fourteenth Amendment Equal Protection | Public schools were segregated by law | State-mandated racial segregation in public schools is inherently unequal and violates Equal Protection | Compare race discrimination, equal protection, civil rights, or the relationship between judicial rulings and implementation |
| Baker v. Carr (1962) | Fourteenth Amendment Equal Protection; justiciability | Tennessee legislative districts had large population disparities and had not been reapportioned for decades | Federal courts may hear Equal Protection challenges to legislative apportionment; the claim is not automatically barred as a political question | Compare malapportionment /redistricting cases. Keep Baker’s justiciability rule distinct from later one-person-one-vote holdings |
| Engel v. Vitale (1962) | First Amendment Establishment Clause | New York public schools used a state-composed prayer | Government may not compose and sponsor an official prayer in public school | Compare school-sponsored religion with personal religious exercise; identify the government’s role in creating or directing the religious activity |
| Gideon v. Wainwright (1963) | Sixth Amendment via Fourteenth Due Process | Gideon, unable to afford counsel in a Florida felony case, was required to defend himself | States must provide appointed counsel to indigent defendants in felony prosecutions | Compare criminal procedure, incorporation, and state obligations under incorporated Bill of Rights protections |
| Tinker v. Des Moines (1969) | First Amendment speech | Students wore black armbands to protest the Vietnam War; the school prohibited the expression | Students retain speech rights at school; officials need material and substantial disruption, or a supportable forecast of it, to restrict this kind of expression | Compare student expression. Focus on facts showing disruption, school sponsorship, location, and the school’s justification |
| Required case | Constitutional basis | Essential facts | Holding / reasoning | Best comparison hook |
|---|---|---|---|---|
| New York Times Co. v. United States (1971) | First Amendment press; prior restraint | The federal government sought to stop publication of the Pentagon Papers | The government failed to meet the heavy burden required for prior restraint | Compare publication bans, national-security claims, prior restraint, and the difference between punishing speech after publication and blocking it in advance |
| Wisconsin v. Yoder (1972) | First Amendment Free Exercise | Amish parents objected to compulsory schooling beyond eighth grade on religious grounds | On the specific facts, the state’s compulsory-schooling interest did not justify the burden on Amish religious practice | Compare free exercise conflicts. Use the specific burden and government interest; do not turn Yoder into a rule that religious objections always prevail |
| Shaw v. Reno (1993) | Fourteenth Amendment Equal Protection | North Carolina created an unusually shaped majority-minority congressional district in a redistricting plan | A redistricting plan in which race predominates can be challenged under Equal Protection; racial classifications can trigger strict scrutiny | Compare racial gerrymandering. Distinguish race-based districting from ordinary partisan or geographic line drawing |
| United States v. Lopez (1995) | Commerce Clause | A student possessed a gun in a school zone under a federal statute lacking an adequate interstate-commerce connection | The Commerce Clause did not authorize federal regulation of this local, noneconomic activity on the facts presented | Compare the outer limits of congressional commerce power; ask whether the regulated activity is economic and how it connects to interstate commerce |
| McDonald v. Chicago (2010) | Second Amendment via Fourteenth Due Process | Chicago handgun restrictions were challenged after the Court recognized an individual self-defense right | The Second Amendment right to keep and bear arms for self-defense applies to state and local governments through the Fourteenth Amendment | Compare selective incorporation and state/local restrictions on an incorporated liberty |
| Citizens United v. FEC (2010) | First Amendment political speech | Federal law restricted corporate-funded electioneering communications and independent political spending | Government may not ban independent political expenditures because the speaker is a corporation or union; the case concerns independent spending, not an unlimited right to contribute directly to candidates | Compare independent expenditures with direct contributions, campaign-finance restrictions, and political speech |
Table B.2 Every required case, retrievable by constitutional basis, facts, holding, and comparison use.
Retrieval rule: for every required case, produce four things without notes: (1) the constitutional clause or right, (2) one fact that drove the dispute, (3) the holding, and (4) one sentence explaining why those facts produced that holding. In a SCOTUS Comparison, do not stop after recalling the required case. Use the supplied case’s facts to state the similarity or difference explicitly.
