AP US Government & Politics – Bill of Rights and Selective Incorporation (14th Amendment)


What This Is

The Bill of Rights (first 10 amendments to the U.S. Constitution) protects individual liberties like free speech, religion, and due process from federal government overreach. Selective incorporation is the process by which the Supreme Court has applied most (but not all) of these protections to state governments via the 14th Amendment’s Due Process Clause. This matters on the AP exam because it’s a core example of how the Court interprets constitutional limits on government power—especially in landmark cases like Gitlow v. New York (1925), where the Court first ruled that states must respect free speech. Without incorporation, states could (and historically did) ignore rights like the 4th Amendment’s protection against unreasonable searches, leaving citizens vulnerable to local abuses.


Key Terms & Concepts

  • Bill of Rights: The first 10 amendments to the U.S. Constitution, ratified in 1791, guaranteeing individual liberties (e.g., speech, religion, fair trials) and limiting federal power.
  • 14th Amendment (1868): Added after the Civil War; includes the Due Process Clause (“No state shall deprive any person of life, liberty, or property without due process of law”) and the Equal Protection Clause.
  • Selective Incorporation: The Supreme Court’s gradual process of applying most (but not all) Bill of Rights protections to state governments via the 14th Amendment’s Due Process Clause. Not all rights are incorporated (e.g., the 3rd Amendment’s quartering of soldiers).
  • Total Incorporation: A rejected theory that the entire Bill of Rights should apply to states at once (never adopted by the Court).
  • Fundamental Rights: Liberties deemed essential to “ordered liberty” (e.g., free speech, right to counsel) that the Court incorporates; others (e.g., grand jury indictments in the 5th Amendment) are not.
  • Due Process Clause (14th Amendment): Used to incorporate Bill of Rights protections; also protects procedural fairness (e.g., fair trials) and substantive rights (e.g., privacy).
  • Equal Protection Clause (14th Amendment): Prohibits states from denying equal protection under the law (key for civil rights cases like Brown v. Board).
  • Incorporation Doctrine: The legal principle that the 14th Amendment extends Bill of Rights protections to state actions.
  • Prior Restraint: Government censorship of speech before it’s published (e.g., Near v. Minnesota, 1931, incorporated free press to states).
  • Exclusionary Rule: Evidence obtained illegally (e.g., without a warrant) cannot be used in court (Mapp v. Ohio, 1961, incorporated the 4th Amendment to states).
  • Right to Privacy: Not explicitly in the Bill of Rights but inferred from amendments (e.g., 1st, 3rd, 4th, 9th) and incorporated via Griswold v. Connecticut (1965) and Roe v. Wade (1973).

Step-by-Step: How to Analyze a Selective Incorporation Case

Use this process for FRQs or multiple-choice questions about incorporation:

  1. Identify the Right at Issue
  2. Is it a Bill of Rights protection (e.g., 1st Amendment free speech, 6th Amendment right to counsel)?
  3. Example: In Gideon v. Wainwright (1963), the right is the 6th Amendment’s guarantee of a lawyer.

  4. Check if the Case Involves State Action

  5. Incorporation only applies to state governments (not private actors or the federal government).
  6. Example: Gitlow v. New York (1925) involved a state law banning socialist pamphlets.

  7. Determine if the Right is Incorporated

  8. Ask: Has the Supreme Court ruled that this right applies to states via the 14th Amendment?
  9. Use the “Fundamental Rights” test: Is the right essential to liberty? (Most are, but not all—e.g., 5th Amendment’s grand jury requirement is not incorporated.)
  10. Example: McDonald v. Chicago (2010) incorporated the 2nd Amendment to states.

  11. Apply the 14th Amendment’s Due Process Clause

  12. The Court asks: Does the state’s action violate a “fundamental principle of liberty and justice”?
  13. Example: In Mapp v. Ohio, the Court ruled that states must exclude illegally obtained evidence (4th Amendment).

  14. Evaluate the Impact

  15. How does incorporation limit state power? How does it expand individual rights?
  16. Example: Miranda v. Arizona (1966) required states to inform suspects of their rights (5th Amendment self-incrimination).

Common Mistakes

  • Mistake: Assuming all Bill of Rights protections apply to states.
  • Correction: Only most are incorporated. Exceptions include:

    • 3rd Amendment (quartering soldiers)
    • 5th Amendment’s grand jury requirement
    • 7th Amendment’s right to a jury in civil cases
    • 8th Amendment’s excessive fines clause (until Timbs v. Indiana, 2019).
  • Mistake: Confusing the Due Process Clause with the Equal Protection Clause of the 14th Amendment.

  • Correction:

    • Due Process = Incorporates Bill of Rights to states (e.g., Gitlow).
    • Equal Protection = Prohibits discrimination (e.g., Brown v. Board).
  • Mistake: Thinking incorporation happened all at once.

  • Correction: It’s a gradual process (e.g., free speech in 1925, right to counsel in 1963, 2nd Amendment in 2010).

  • Mistake: Forgetting that incorporation only applies to government actions, not private individuals.

  • Correction: The Bill of Rights limits government power, not private businesses or citizens (e.g., a private employer can fire you for speech, but the government can’t).

  • Mistake: Misidentifying which amendment a right comes from.

  • Correction:
    • Free speech = 1st Amendment
    • Right to bear arms = 2nd Amendment
    • No unreasonable searches = 4th Amendment
    • Right to a lawyer = 6th Amendment
    • No cruel/unusual punishment = 8th Amendment

AP Exam Insights

  1. FRQ Hot Topic:
  2. Expect a Document-Based Question (DBQ) or Concept Application FRQ asking you to:
    • Explain how a specific Bill of Rights protection was incorporated (e.g., “Using Gideon v. Wainwright, explain how the 6th Amendment was applied to states”).
    • Compare incorporation to another constitutional principle (e.g., federalism, judicial review).
  3. Trap: The FRQ might ask about a non-incorporated right (e.g., “Explain why the 5th Amendment’s grand jury requirement does not apply to states”).

  4. Multiple-Choice Traps:

  5. Distinction: Incorporation vs. reverse incorporation (applying state constitutional rights to the federal government—rare and not tested).
  6. Tricky Cases: Know which rights are not incorporated (e.g., 3rd Amendment, 7th Amendment civil juries).
  7. Dates Matter: The exam loves testing the order of incorporation (e.g., free speech in 1925, right to counsel in 1963).

  8. Key Court Cases to Memorize:

  9. Incorporation Cases:
    • Gitlow v. New York (1925) – 1st Amendment free speech
    • Near v. Minnesota (1931) – 1st Amendment free press
    • Mapp v. Ohio (1961) – 4th Amendment exclusionary rule
    • Gideon v. Wainwright (1963) – 6th Amendment right to counsel
    • McDonald v. Chicago (2010) – 2nd Amendment
  10. Non-Incorporation Cases:

    • Hurtado v. California (1884) – 5th Amendment grand jury not incorporated
    • Minneapolis & St. Louis R.R. v. Bombolis (1916) – 7th Amendment civil juries not incorporated
  11. Thematic Connections:

  12. Federalism: Incorporation limits state power, shifting authority to the federal judiciary.
  13. Judicial Activism: The Court’s role in expanding rights (e.g., Roe v. Wade via privacy).
  14. Civil Liberties vs. Civil Rights: Incorporation protects liberties (freedom from government), while the Equal Protection Clause protects rights (equality under law).

Quick Check Questions

  1. Multiple Choice: Which of the following Bill of Rights protections has not been incorporated to apply to state governments? A) 1st Amendment free speech B) 4th Amendment protection against unreasonable searches C) 5th Amendment grand jury requirement D) 6th Amendment right to a lawyer

Answer: C. The 5th Amendment’s grand jury requirement has not been incorporated (Hurtado v. California).

  1. Short FRQ: “The 14th Amendment’s Due Process Clause has been used to apply most Bill of Rights protections to state governments.” Using a specific Supreme Court case, explain how this process works.

Answer: In Gideon v. Wainwright (1963), the Supreme Court ruled that the 6th Amendment’s right to a lawyer is a fundamental right essential to a fair trial. Using the 14th Amendment’s Due Process Clause, the Court incorporated this right to states, requiring them to provide attorneys to indigent defendants.

  1. Multiple Choice: The Supreme Court’s decision in McDonald v. Chicago (2010) is significant because it: A) Overturned Roe v. Wade B) Incorporated the 2nd Amendment to state governments C) Applied the 8th Amendment’s ban on cruel punishment to states D) Upheld a state law banning same-sex marriage

Answer: B. McDonald v. Chicago incorporated the 2nd Amendment’s right to bear arms to states via the 14th Amendment.
