The phrase “the practice of selective incorporation means that the Bill of Rights will” often appears in constitutional law classes, civics exams, and legal discussions. It is the legal process by which the Supreme Court applies specific provisions of the Bill of Rights to state governments, one by one, through the Fourteenth Amendment’s Due Process Clause.
Without it, your constitutional protections could vary significantly depending on where you lived. Today, freedoms such as free speech, religious liberty, the right to counsel, and protection against unreasonable searches generally apply at both the federal and state levels because of this legal doctrine.
This guide explains incorporation in plain English. You’ll learn what it means, why it matters, how it developed, and which rights have been incorporated through landmark Supreme Court decisions. While it may sound technical, the concept is one of the most important principles in American constitutional law.

What Does the Practice of Selective Incorporation Mean?
It is a constitutional doctrine by which the U.S. Supreme Court has gradually applied most protections in the Bill of Rights to state governments through its interpretation of the Due Process Clause of the Fourteenth Amendment.
In simple terms, the constitutional doctrine means that the Bill of Rights protects individuals not only from the federal government but also from unconstitutional actions by state governments. Instead of applying all constitutional rights at once, the Supreme Court reviewed individual rights one by one and decided whether each was fundamental enough to extend to the states.
Before Incorporation: The Barron v. Baltimore Problem
In 1833, the Supreme Court made a landmark ruling in Barron v. Baltimore. Chief Justice John Marshall held that the Bill of Rights was intended solely as a limitation on federal power; states could do as they pleased.
This meant a state could, theoretically:
- Restrict your freedom of speech.
- Deny you a fair trial.
- Allow unreasonable searches of your home.
- Seize your property without compensation.
And for much of American history, some states did exactly that.
The Gamechanger: The Fourteenth Amendment (1868)
After the Civil War, Congress passed the Fourteenth Amendment, which includes this critical line:
“…nor shall any State deprive any person of life, liberty, or property, without due process of law.”
This Due Process Clause became the constitutional vehicle for incorporation. Over the following decades, the Supreme Court would use it to apply federal rights protections directly against state governments.
Why Was Constitutional Doctrine Necessary?
When the Bill of Rights was adopted in 1791, it restricted only the federal government. State governments retained broad authority over many legal matters. This created inconsistent protection across the country.
Following the Civil War, the Fourteenth Amendment was ratified in 1868, introducing protections against state violations of individual rights. However, it took decades of Supreme Court decisions before those protections became meaningful through constitutional doctrine.
How Does Selective Incorporation Work?
Instead of automatically applying every constitutional protection to states, the Supreme Court asks one central question.
Is the right fundamental to liberty and justice?
If the answer is yes, that protection becomes enforceable against state governments through the Fourteenth Amendment.
The Process
- A constitutional dispute reaches the Supreme Court.
- The court examines the specific rights.
- The court determines whether the right is fundamental.
- If incorporated, state governments must respect constitutional protection.
Historical Background
Understanding constitutional doctrine becomes easier when you know the timeline.
| Year | Constitutional Event | Importance |
| 1791 | The Bill of Rights was adopted | Limited only to the federal government |
| 1868 | Fourteenth Amendment ratified | Opened the door for incorporation |
| 1897 | First major incorporation case | Began applying rights to states |
| 1925–1970s | Major incorporation era | Most fundamental rights are incorporated |
| Today | Modern constitutional doctrine | Protects citizens nationwide |
Major Supreme Court Cases That Shaped Incorporation
Several landmark decisions transformed constitutional law.
1. Gitlow v. New York (1925)
The court ruled that freedom of speech applies to state governments. This became one of the most important decisions regarding incorporation.
2. Mapp v. Ohio (1961)
The exclusionary rule became applicable to states. Evidence obtained through illegal searches generally cannot be used in court.
3. Gideon v. Wainwright (1963)
The court guaranteed that defendants facing serious criminal charges have the right to legal counsel even in state courts.
4. Miranda v. Arizona (1966)
Although based partly on the Fifth Amendment, this case strengthened protections against self-incrimination during police questioning.
5. McDonald v. Chicago (2010)
The Second Amendment right to keep and bear arms was incorporated against the states.
Rights That Have Been Incorporated
Below are many constitutional protections that now apply to state governments.
First Amendment
- Freedom of speech.
- Freedom of religion.
- Freedom of the press.
- Peaceful assembly.
- Petitioning the government.
Fourth Amendment
- Protection against unreasonable searches.
- Warrant requirements.
- Privacy protections.
Fifth Amendment
- Protection against double jeopardy.
- Protection against self-incrimination.
Sixth Amendment
- Right to an attorney.
- Speedy trial.
- Public trial.
- Impartial jury.
- Confronting witnesses.
Eighth Amendment
- Protection against cruel and unusual punishment.
Rights That Have Not Been Fully Incorporated
Not every part of the Bill of Rights applies to the states.
Examples include:
- A grand jury indictment is required in many criminal cases.
- Certain aspects of civil jury trials.
- Some provisions of the Third Amendment have rarely been tested.
Important
Selective incorporation does not mean every single constitutional right automatically applies to every state in exactly the same way. Some protections remain partially incorporated or interpreted differently depending on Supreme Court rulings.
Selective Incorporation vs. Total Incorporation
One of the biggest constitutional debates involved whether all rights should apply automatically.
| Selective Incorporation | Total Incorporation |
| Rights added individually | All rights apply automatically. |
| Based on Supreme Court decisions | Would apply the entire Bill of Rights at once. |
| Current constitutional doctrine | Never fully adopted. |
| Evaluates each right separately | Treats every right equally. |
Why Constitutional Doctrine Matters Today?
Most Americans have far more day-to-day interactions with state and local governments than with the federal government. Whether dealing with local police during an investigation, appearing in a state criminal court, attending a public school, voting in state elections, or following local government regulations, state authorities play a significant role in everyday life.
Because of the doctrine of selective incorporation, the fundamental protections guaranteed by the Bill of Rights apply in these situations as well. This means that state governments must respect many of the same constitutional rights as the federal government, ensuring consistent legal protections for citizens across the country.
Benefits of Selective Doctrine
Constitutional doctrine strengthens constitutional protections by ensuring that fundamental rights apply nationwide. It protects individual liberties regardless of where people live, creates greater consistency by requiring states to respect essential constitutional rights, limits the power of both federal and state governments, and reinforces judicial review by allowing courts to strike down laws that violate the Constitution. Together, these benefits help preserve fairness, equality, and the rule of law nationwide.
Key Takeaways
It extends many protections in the Bill of Rights to state governments.
- The doctrine relies on the Fourteenth Amendment’s Due Process Clause.
- Rights are incorporated individually rather than all at once.
- Most fundamental freedoms now apply nationwide.
- Supreme Court decisions continue shaping constitutional protections.
Final Thoughts
Understanding the practice of selective incorporation means that the Bill of Rights will protect citizens against many actions taken by state governments, which is essential for anyone studying American government or constitutional law.
This doctrine transformed the Constitution from a document that primarily limited federal authority into one that safeguards fundamental freedoms across the entire nation. Although the process developed gradually through landmark Supreme Court decisions, its impact is enormous.
Today, freedoms such as speech, religion, fair trials, legal representation, and protection from unreasonable searches are protected whether the government involved is federal or state. Selective incorporation remains one of the strongest foundations of constitutional liberty, ensuring that fundamental rights are respected consistently throughout the United States.
