Required Supreme Court Cases
Marbury v. Madison (1803) The Supreme Court established judicial review, meaning the Court can strike down laws or government actions that violate the Constitution.
McCulloch v. Maryland (1819) The Supreme Court ruled that Congress has implied powers through the Necessary and Proper Clause and that states cannot tax the federal government. This strengthened federal power over state power.
Schenck v. United States (1919) The Supreme Court ruled that speech can be restricted if it creates a “clear and present danger,” especially during wartime. This limited First Amendment free speech protections.
Brown v. Board of Education (1954) The Supreme Court ruled that racial segregation in public schools violates the Equal Protection Clause of the Fourteenth Amendment. This overturned “separate but equal” from Plessy v. Ferguson.
Baker v. Carr (1962) The Supreme Court ruled that federal courts can hear cases about redistricting and reapportionment. This helped establish the principle of “one person, one vote.”
Engel v. Vitale (1962) The Supreme Court ruled that school-sponsored prayer in public schools violates the Establishment Clause of the First Amendment, even if the prayer is voluntary.
Gideon v. Wainwright (1963) The Supreme Court ruled that states must provide attorneys to defendants who cannot afford one in serious criminal cases. This applied the Sixth Amendment right to counsel to the states through the Fourteenth Amendment.
Tinker v. Des Moines Independent Community School District (1969) The Supreme Court ruled that students have free speech rights in public schools as long as their expression does not substantially disrupt the school environment.
New York Times Co. v. United States (1971) The Supreme Court ruled that the government could not use prior restraint to stop publication of the Pentagon Papers. This strengthened freedom of the press under the First Amendment.
Wisconsin v. Yoder (1972) The Supreme Court ruled that Amish parents could remove their children from school after eighth grade because of their religious beliefs. This protected the Free Exercise Clause of the First Amendment.
Roe v. Wade (1973) The Supreme Court ruled that the Constitution protected a right to abortion under the right to privacy. However, this case was later overturned by Dobbs v. Jackson Women’s Health Organization in 2022.
Shaw v. Reno (1993) The Supreme Court ruled that oddly shaped majority-minority districts may violate the Equal Protection Clause if race is the main factor in redistricting. This case limited racial gerrymandering.
United States v. Lopez (1995) The Supreme Court ruled that Congress exceeded its Commerce Clause power by banning guns near schools. This limited federal power and strengthened states’ rights.
McDonald v. Chicago (2010) The Supreme Court ruled that the Second Amendment right to keep and bear arms applies to the states through the Fourteenth Amendment’s Due Process Clause.
Citizens United v. Federal Election Commission (2010) The Supreme Court ruled that corporations and unions have First Amendment political speech rights and that independent political spending cannot be limited. This expanded the role of money in elections.
Foundational Documents
Declaration of Independence (1776) This document declared the colonies’ independence from Britain and argued that government should protect natural rights, including life, liberty, and the pursuit of happiness. It is based on consent of the governed and the right to revolt against tyranny.
Articles of Confederation (1781) This was the first governing document of the United States. It created a weak national government, gave most power to the states, and lacked the power to tax, regulate commerce, or enforce laws effectively.
U.S. Constitution (1787) This document replaced the Articles of Confederation and created a stronger federal government with separation of powers, checks and balances, federalism, and a system for amending the Constitution.
Brutus No. 1 (1787) This Anti-Federalist essay argued against ratifying the Constitution because it gave too much power to the national government. Brutus feared that the Necessary and Proper Clause and Supremacy Clause would destroy state power and individual liberty.
Federalist No. 10 (1787) James Madison argued that factions are inevitable, but their effects can be controlled through a large republic. A large republic makes it harder for one faction to dominate the government.
Federalist No. 51 (1788) James Madison argued for separation of powers and checks and balances. The main idea is that “ambition must be made to counteract ambition” so no branch becomes too powerful.
Federalist No. 70 (1788) Alexander Hamilton argued for a strong, energetic, single executive. He believed one president would provide accountability, quick decision-making, and national security.
Federalist No. 78 (1788) Alexander Hamilton argued that the judiciary would be the “least dangerous branch” because it has neither the power of the purse nor the sword. He defended judicial review and lifetime tenure for federal judges.
Letter from Birmingham Jail (1963) Martin Luther King Jr. defended civil disobedience against unjust laws. He argued that people have a moral responsibility to disobey unjust laws and that justice delayed is justice denied.
