Every term in Unit 3

All 24 terms we publish for Civil Liberties & Civil Rights, with definitions. Reading them through is the fastest way to find the ones you cannot define — then drill those in cram mode until you can produce them without the prompt.

Selective incorporation: Applying Bill of Rights protections to the states one at a time through the Fourteenth Amendment's due process clause.
Civil liberties vs civil rights: Liberties are protections from government action; rights are protections of equal treatment and government obligations to secure it.
Establishment clause: Government may not establish religion. The line between accommodation and endorsement is the recurring dispute.
Free exercise clause: Protects religious practice, but not without limit — general laws of neutral application can burden practice.
Engel v. Vitale (1962): Required case. School-sponsored prayer violates the establishment clause even when non-denominational and voluntary.
Wisconsin v. Yoder (1972): Required case. Compelling Amish children to attend school past eighth grade violated free exercise, given the sincerity and centrality of the belief.
Schenck v. United States (1919): Required case. Speech creating a "clear and present danger" may be restricted; the standard for wartime speech restriction.
Tinker v. Des Moines (1969): Required case. Students retain free speech in school unless it materially disrupts education — armbands protesting Vietnam were protected.
New York Times v. United States (1971): Required case. Prior restraint carries a heavy presumption against it; the government could not block publication of the Pentagon Papers.
Symbolic speech: Expressive conduct protected by the First Amendment — armbands, flag burning, silent protest.
Prior restraint: Government blocking expression before publication. Presumptively unconstitutional, which is a stronger protection than after-the-fact liability.
McDonald v. Chicago (2010): Required case. Incorporated the Second Amendment against the states through the Fourteenth Amendment.
Gideon v. Wainwright (1963): Required case. Incorporated the Sixth Amendment right to counsel, requiring states to provide an attorney to defendants who cannot afford one.
Miranda rights: Suspects in custody must be informed of the rights to silence and counsel before interrogation, from Miranda v. Arizona.
Exclusionary rule: Evidence obtained unconstitutionally is generally inadmissible, from Mapp v. Ohio. Deters violations by removing their payoff.
Right to privacy: Not enumerated; inferred from several amendments in Griswold and extended in Roe. The basis for a long line of contested decisions.
Roe v. Wade (1973): Required case. Found a privacy-based right to abortion with a trimester framework. Overturned by Dobbs in 2022.
Equal protection clause: Fourteenth Amendment guarantee that states not deny equal protection of the laws — the engine of civil rights litigation.
Brown v. Board of Education (1954): Required case. Segregated public schools are inherently unequal, overturning Plessy in education.
Civil Rights Act of 1964: Banned discrimination in public accommodations and employment, and allowed the withholding of federal funds from segregated programs.
Voting Rights Act of 1965: Suspended literacy tests and sent federal examiners into resistant jurisdictions, producing an immediate surge in Black registration.
Title IX: Bars sex discrimination in federally funded education programs, transforming women's access to athletics and professional training.
Affirmative action: Policies considering historically disadvantaged status in admissions or hiring. Repeatedly narrowed by the Court and now largely barred in college admissions.
Strict scrutiny: The hardest test to satisfy: a law classifying by race must serve a compelling interest and be narrowly tailored. Most such laws fail it.

What examiners penalize here

Sort the First Amendment cases by clause: **Engel** (Establishment), **Yoder** (Free Exercise), **Tinker** (symbolic speech), **Schenck** (limits on speech — clear and present danger), **NYT v. US** (press, no prior restraint). Naming the clause and the standard together earns the point.
Both **Gideon** (right to counsel) and **McDonald** (right to bear arms) are incorporation cases decided under the **Fourteenth Amendment**. If a prompt asks how a Bill of Rights protection came to bind a *state*, "selective incorporation through the Due Process Clause" is your framework.
Keep the concepts distinct: **civil liberties** are freedoms *from* government interference (speech, religion, due process); **civil rights** are protections *by* government against discrimination (equal protection). Brown and the Equal Protection Clause are civil *rights*; the First Amendment cases are civil *liberties*.
