Understanding Selective Incorporation
Selective incorporation is the constitutional doctrine through which the Supreme Court applies specific protections found in the Bill of Rights to state and local governments. Originally, the first ten amendments restricted only the federal government. Following the ratification of the Fourteenth Amendment in 1868, the Court gradually used the Due Process Clause to ensure that state governments couldn't infringe upon fundamental civil liberties. Instead of absorbing the entire Bill of Rights at once—a rejected theory known as total incorporation—the justices evaluated rights individually on a case-by-case basis.
For AP United States Government and Politics students, mastering this concept requires tracking how national power expanded at the expense of state autonomy. When analyzing constitutional questions, you'll find that selective incorporation serves as the primary engine driving modern civil liberties protection. If a state passes a law that violates a fundamental freedom like free speech or the right to counsel, the Supreme Court strikes it down by citing how the Fourteenth Amendment absorbs that specific federal protection.
The Constitutional Blueprint: The Fourteenth Amendment
To understand how selective incorporation functions, you have to look closely at the text of the Fourteenth Amendment. Section 1 states that no state shall "deprive any person of life, liberty, or property, without due process of law." This phrasing mirrors the Fifth Amendment's due process clause, which previously bound only federal authorities.
For decades after the Civil War, the Supreme Court resisted applying the Bill of Rights to the states. In the landmark case Barron v. Baltimore (1833), Chief Justice John Marshall ruled that the Bill of Rights restricted only the national government. Everything changed after the Fourteenth Amendment passed. Jurists began to argue that certain federal rights were so essential to a free society that they formed part of the "liberty" protected from state interference.
This evolution shifted American federalism. Power flowed from state legislatures toward the federal judiciary, which set a uniform national floor for civil rights. States could provide more protection than the federal baseline, but they couldn't offer less.
Total Incorporation Versus Selective Incorporation
Constitutional scholars and early twentieth-century Supreme Court justices debated two primary theories for applying the Bill of Rights to the states:
- Total Incorporation: This approach argued that the Fourteenth Amendment automatically incorporated every single provision of the Bill of Rights as a single bundle, applying all of it to the states immediately. Justice Hugo Black famously championed this view, but a majority of the Supreme Court never accepted it.
- Selective Incorporation: This method requires the Court to evaluate specific rights one at a time. A right becomes incorporated only if the justices determine it is "fundamental" and "implicit in the concept of ordered liberty".
Because of this incremental approach, incorporation took place over many decades. Some clauses of the Bill of Rights, such as the right to a grand jury indictment in criminal cases, remain unincorporated to this day.
Landmark Supreme Court Cases to Know for AP Gov
The Supreme Court Historical Society tracks how individual amendments were incorporated through specific rulings. You must know these pivotal cases for your exams.
Gitlow v. New York (1925)
This case marks the birth of modern selective incorporation. Benjamin Gitlow, a socialist, was convicted under New York's criminal anarchy law for distributing leftist pamphlets. The Supreme Court upheld his conviction, but in doing so, it officially assumed that freedom of speech and of the press were among the fundamental personal rights protected by the Due Process Clause of the Fourteenth Amendment from impairment by the states. It was the first time a First Amendment protection applied to state action.
Mapp v. Ohio (1961)
Dollree Mapp's home was searched by police officers without a proper search warrant. They discovered illicit materials and arrested her. The Supreme Court ruled that evidence obtained through a violation of the Fourth Amendment is inadmissible in state courts, a principle known as the exclusionary rule. This incorporated the Fourth Amendment protection against unreasonable searches and seizures.
Gideon v. Wainwright (1963)
Clarence Earl Gideon was accused of breaking into a poolroom in Florida. He couldn't afford an attorney and asked the state judge to appoint one for him, but Florida law only permitted appointed counsel in capital cases. Gideon defended himself poorly and was convicted. The Supreme Court unanimously ruled that the Sixth Amendment's guarantee of counsel is a fundamental right essential to a fair trial, forcing states to provide free lawyers to indigent defendants in felony cases.
McDonald v. Chicago (2010)
Following its earlier ruling that the Second Amendment protects an individual right to bear arms in District of Columbia v. Heller, the Court addressed whether that right applies to state and local governments. Otis McDonald challenged Chicago's strict handgun bans. The Court ruled 5-4 that the Second Amendment is fully applicable to the states through the Fourteenth Amendment's Due Process Clause, incorporating the right to keep and bear arms for self-defense.
How Selective Incorporation Affects Modern Federalism
Selective incorporation fundamentally alters how local, state, and federal laws interact. When a city or state passes an ordinance that restricts personal freedoms, citizens don't just rely on state constitutions. They file lawsuits in federal court alleging violations of incorporated Bill of Rights amendments.
This dynamic creates continuous friction between states' rights and federal oversight. For instance, when local police departments adopt interrogation tactics or search protocols, they must comply with federal constitutional standards established by rulings like Miranda v. Arizona. If they don't, federal courts invalidate their procedures.

Common Misunderstandings on AP Exams
Students often lose points on free-response questions because they confuse incorporation mechanisms or misapply the amendments. Keep these points straight:
- Equal Protection vs. Due Process: The Equal Protection Clause of the Fourteenth Amendment deals primarily with discrimination and civil rights (such as racial equality). Selective incorporation relies almost entirely on the Due Process Clause to absorb civil liberties from the Bill of Rights.
- Total vs. Selective: Don't write that the Supreme Court incorporated the entire Bill of Rights in a single historic ruling. Emphasize that it's a slow, case-by-case process.
- Federal vs. State: Remember that the original Bill of Rights restrained only federal power. Incorporation brought state governments under those exact same restrictions.
Frequently Asked Questions
What clause of the Fourteenth Amendment enables selective incorporation?
The Due Process Clause is the legal vehicle used by the Supreme Court to incorporate Bill of Rights protections. It protects individuals from state actions that deny fundamental liberties.
Are all amendments in the Bill of Rights incorporated?
No. Some provisions, such as the Fifth Amendment requirement for a grand jury indictment in state criminal trials or the Seventh Amendment right to a jury trial in civil cases, have not been incorporated.
Why did the Supreme Court prefer selective incorporation over total incorporation?
The justices favored selective incorporation because it allows the Court to exercise judicial restraint, examining each specific right based on historical tradition and whether it's truly fundamental to ordered liberty.
How does selective incorporation relate to federalism?
It shifts power toward the federal government by establishing a uniform national standard for civil liberties that state laws cannot cross. States retain police powers, but those powers must respect incorporated federal rights.
