Civil Rights and Civil Liberties in the US

Civil liberties are protections from government action — freedom of speech, religion, and protection from unreasonable searches. Civil rights are the rights to equal treatment and protection from discrimination by both government and (in some contexts) private actors. Both are fundamental to the American constitutional order.

The Distinction: Liberties vs. Rights

Civil libertiesGovernment infringement on individual freedomsBill of Rights (1st–10th Amendments), 14th Amendment due process

The Bill of Rights and the 14th Amendment

The Bill of Rights (Amendments 1–10) was originally interpreted as applying only to the federal government. States could theoretically violate free speech, run established churches, or conduct unreasonable searches without federal consequence.

The 14th Amendment (1868) changed this — its Due Process Clause ("nor shall any State deprive any person of life, liberty, or property, without due process of law") has been used by the Supreme Court to incorporate most Bill of Rights protections and apply them to state governments.

The Incorporation Doctrine

The Court applies Bill of Rights protections to states through selective incorporation — case by case:

AmendmentKey RightsIncorporated Against States?
1stSpeech, press, religion, assemblyYes
2ndKeep and bear armsYes (McDonald v. Chicago, 2010)
4thUnreasonable search and seizureYes (Mapp v. Ohio, 1961)
5thSelf-incrimination, double jeopardy, due processPartially (grand jury requirement not incorporated)
6thSpeedy trial, jury trial, right to counselYes
8thCruel and unusual punishmentYes

The First Amendment

The 1st Amendment contains five distinct rights:

"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."

Freedom of Speech

The US has among the strongest free speech protections in the world. The government generally cannot regulate speech based on its content — even offensive, hateful, or deeply unpopular speech is protected.

Unprotected speech (the narrow exceptions):

  • Incitement to imminent lawless action (Brandenburg v. Ohio, 1969) — not mere advocacy of illegal ideas; must be directed at producing and likely to produce imminent lawless action
  • True threats — serious expressions of intent to commit violence
  • Obscenity (using the Miller test — community standards, patently offensive, no serious value)
  • Defamation (false statements of fact causing harm; actual malice required for public figures per NYT v. Sullivan, 1964)
  • Fighting words — personally abusive epithets that provoke immediate breach of peace

Protected speech (surprising examples): Flag burning (Texas v. Johnson, 1989), Ku Klux Klan advocacy (Brandenburg), Nazi marches, violent video games, campaign spending (Citizens United v. FEC, 2010).

Freedom of Religion — Two Clauses

Establishment Clause: Government cannot establish an official religion, promote religion over non-religion, or endorse a religion. Engel v. Vitale (1962): school-sponsored prayer is unconstitutional. The three-part Lemon test (largely abandoned; now Kennedy v. Bremerton, 2022 uses historical practices approach).

Free Exercise Clause: Government cannot substantially burden religious practice without a compelling interest. Employment Division v. Smith (1990): neutral, generally applicable laws can burden religion incidentally. Fulton v. City of Philadelphia (2021): government cannot exclude religious organisations from generally available programs based on their religious beliefs.

Equal Protection — The 14th Amendment

The Equal Protection Clause of the 14th Amendment prohibits states from denying "any person within its jurisdiction the equal protection of the laws." The Supreme Court applies different levels of scrutiny depending on the classification:

Levels of Scrutiny

StandardWhen AppliedGovernment Must Show
Strict scrutinySuspect classifications (race, national origin) and fundamental rightsLaw is necessary to achieve a compelling government interest, and narrowly tailored. Almost always → law struck down.
Intermediate scrutinyQuasi-suspect classifications (sex, legitimacy)Law is substantially related to an important government interest
Rational basisAll other classificationsLaw is rationally related to a legitimate government interest. Almost always → law upheld.

Landmark equal protection cases:

  • Brown v. Board of Education (1954): Racially segregated schools are inherently unequal — struck down the "separate but equal" doctrine of Plessy v. Ferguson (1896)
  • Loving v. Virginia (1967): Laws banning interracial marriage are unconstitutional
  • Reed v. Reed (1971): First sex discrimination case won under equal protection
  • United States v. Virginia (1996): Virginia Military Institute's male-only admissions policy was unconstitutional
  • Obergefell v. Hodges (2015): Same-sex couples have a fundamental right to marry

The Civil Rights Movement and Legislation

The Supreme Court's decisions were necessary but not sufficient. Congress enacted landmark legislation:

Civil Rights Act of 1964

The most comprehensive civil rights legislation since Reconstruction. Title II: Prohibits discrimination in public accommodations (hotels, restaurants, theaters) based on race, color, religion, national origin. Title VI: Prohibits discrimination in federally funded programs. Title VII: Prohibits employment discrimination based on race, color, religion, sex, or national origin; established the Equal Employment Opportunity Commission (EEOC).

Voting Rights Act of 1965

Responded to systematic denial of voting rights to Black Americans in the South. Banned literacy tests and other discriminatory voting practices; required federal pre-clearance (Section 5) of changes to voting laws in covered jurisdictions (partially gutted by Shelby County v. Holder, 2013).

Civil Rights Act of 1968 (Fair Housing Act)

Prohibited discrimination in the sale, rental, and financing of housing based on race, color, religion, national origin; later amended to add sex, disability, and familial status.

Americans with Disabilities Act (1990)

Prohibits discrimination against people with disabilities in employment (Title I), public services (Title II), and public accommodations (Title III). Requires "reasonable accommodations" in the workplace.

Due Process — Procedural and Substantive

The 5th and 14th Amendments both contain Due Process Clauses. Courts have identified two types:

Procedural due process: Before the government deprives you of life, liberty, or property, it must give you fair procedures — notice, a hearing, a neutral decision-maker. The required procedures vary with the significance of the interest at stake.

Substantive due process: Some rights are so fundamental that the government cannot infringe them at all, even with full procedural protections. Examples: right to marry (Loving v. Virginia), right to have children, right to direct the education of your children (Pierce v. Society of Sisters), right to privacy (see Griswold v. Connecticut, Lawrence v. Texas).

Dobbs v. Jackson Women's Health Organization (2022) overruled Roe v. Wade on substantive due process grounds, returning abortion regulation to the states.

Study Snapshot

Civil Rights and Liberties — Bill of Rights protections (1st through 8th Amendments), incorporation doctrine (14th Amendment applies rights to states), three levels of equal protection scrutiny (strict/intermediate/rational basis), civil rights legislation (1964/1965/1968), and due process (procedural vs. substantive).
