3.7 Selective Incorporation
The Bill of Rights originally limited only the national government. Through selective incorporation, the Supreme Court has used the Fourteenth Amendment's Due Process Clause to apply most of its protections to the states, one right and one case at a time. Today nearly all of the Bill of Rights binds state and local governments.
Key terms
- selective incorporation
- Fourteenth Amendment
- due process clause
The starting point: Barron v. Baltimore
In Barron v. Baltimore (1833), a wharf owner argued that the city had ruined his business without paying him, violating the Fifth Amendment's takings clause. The Court ruled that the Bill of Rights restrained only the national government, not the states. So for decades, a state could limit speech or religion without violating the federal Constitution (state constitutions had their own protections).
The Fourteenth Amendment changes the game
Ratified in 1868 after the Civil War, the Fourteenth Amendment says no state shall “deprive any person of life, liberty, or property, without due process of law.” The Due Process Clause gave the Court a way to apply federal rights against the states: if a right in the Bill of Rights is part of the “liberty” protected by due process, then states must respect it too.
Selective incorporation is the process of doing this right by right, as cases come up, instead of applying the whole Bill of Rights at once. Justice Hugo Black argued for total incorporation of all of it, but the Court never adopted that approach.
Milestones
| Case | Year | Right applied to the states |
|---|---|---|
| Gitlow v. New York | 1925 | Freedom of speech (the Court assumed it was incorporated) |
| Near v. Minnesota | 1931 | Freedom of the press |
| Cantwell v. Connecticut | 1940 | Free exercise of religion |
| Everson v. Board of Education | 1947 | Establishment clause |
| Mapp v. Ohio | 1961 | Exclusionary rule for illegally obtained evidence (Fourth Amendment) |
| Gideon v. Wainwright | 1963 | Right to a lawyer in felony cases (Sixth Amendment) |
| Malloy v. Hogan | 1964 | Protection against self-incrimination (Fifth Amendment) |
| Duncan v. Louisiana | 1968 | Jury trial in serious criminal cases (Sixth Amendment) |
| McDonald v. Chicago | 2010 | Right to keep and bear arms (Second Amendment) |
| Timbs v. Indiana | 2019 | Ban on excessive fines (Eighth Amendment) |
What hasn't been incorporated
A few protections still apply only to the national government: the Third Amendment's ban on quartering soldiers (the Supreme Court has never ruled on it), the Fifth Amendment's requirement of a grand jury indictment, and the Seventh Amendment's right to a jury in civil cases. That's why many states can bring felony charges without a grand jury.
Why it matters
Incorporation shifted power toward the national government and the federal courts. Most criminal cases are handled by state and local police and courts, so incorporating the rights of the accused (3.8) changed policing and trials nationwide. It also connects to federalism (1.8): the Fourteenth Amendment is one of the main constitutional tools that lets federal courts limit what states do.
When you see a modern case about a state or local law and a Bill of Rights freedom, the claim is technically under the Fourteenth Amendment, which makes the relevant right apply to the state.
Worked examples

- Example 1
Explaining incorporation in a scenario
A state law bans newspapers from endorsing candidates. A newspaper sues, citing the First Amendment, which says “Congress shall make no law…abridging the freedom…of the press.” The state argues that the First Amendment limits only Congress. Explain why the state's argument fails.
Show the solutionHide the solution
- Step 1: Acknowledge the text: the First Amendment's wording refers to Congress, and under Barron v. Baltimore the Bill of Rights originally limited only the national government.
- Step 2: Bring in the Fourteenth Amendment: its Due Process Clause bars states from depriving people of liberty without due process.
- Step 3: Explain incorporation: through selective incorporation, the Court has ruled that freedom of the press is part of that protected liberty (Near v. Minnesota, 1931), so it applies to states too.
- Step 4: Conclude: the state is bound by the free press guarantee.
Answer: Freedom of the press has been incorporated through the Fourteenth Amendment's Due Process Clause, so it limits state governments as well as Congress.
Common mistakes
- Saying incorporation happened through the Equal Protection Clause. It happened through the Fourteenth Amendment's Due Process Clause.
- Thinking the entire Bill of Rights was applied at once. It was selective, case by case, over most of the 20th century.
- Claiming every right is incorporated. The Third Amendment, the grand jury requirement and the civil jury right are not.
On the exam
- When a required case involves a state, such as Gideon or McDonald, mention incorporation and the Due Process Clause to show full understanding.
- Multiple-choice questions often ask which amendment made incorporation possible. The answer is the Fourteenth.
