AP Government: Fourteenth Amendment and Incorporation Doctrine

Understanding the Fourteenth Amendment is central to grasping how your constitutional rights are protected not just from the federal government, but from your state and local governments as well. This transformation, achieved through the Incorporation Doctrine, is the story of how the Supreme Court nationalized the Bill of Rights, weaving a single thread of fundamental liberties through the fabric of American federalism and connecting landmark cases you must know.

The Starting Point: A Bill of Rights That Bound Only Congress

For the first 76 years of the Constitution, the Bill of Rights was understood to apply only to the national government. This principle was cemented in the 1833 case Barron v. Baltimore. Barron argued the city damaged his wharf, essentially taking his property without just compensation, violating the Fifth Amendment. The Supreme Court, led by Chief Justice John Marshall, ruled unanimously that the Bill of Rights was designed solely as a limitation on federal power. "The Fifth Amendment must be understood as restraining the power of the general government, not as applicable to the states," Marshall wrote. This meant states could, in theory, establish official religions or conduct unreasonable searches without violating the U.S. Constitution.

This dual system of liberty created a patchwork where fundamental freedoms depended on your state's constitution. The Civil War and the subsequent Reconstruction Era aimed to rectify this imbalance, leading directly to the ratification of the Fourteenth Amendment in 1868.

The Fourteenth Amendment: The Engine of Incorporation

The Fourteenth Amendment contains the critical clauses that became the vehicle for applying the Bill of Rights to the states. Two clauses are paramount in this story:

1. The Privileges or Immunities Clause: "No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States." Many thought this was the direct channel for applying the Bill of Rights to the states.
2. The Due Process Clause: "Nor shall any State deprive any person of life, liberty, or property, without due process of law."

The history of incorporation is, in part, the history of the Court choosing one clause over the other. In the 1873 Slaughter-House Cases, a narrowly interpreted Privileges or Immunities Clause was essentially rendered useless for incorporation. The Court drew a sharp distinction between state citizenship and national citizenship, ruling that the clause only protected a narrow set of rights belonging to national citizenship, like the right to travel to the nation's capital. This controversial decision steered future incorporation efforts toward the Due Process Clause.

Selective Incorporation: The Predominant Method

The Court faced a fundamental question: How should the Due Process Clause be used to apply the Bill of Rights to the states? Two theories emerged:

• Total Incorporation: Argued that the Fourteenth Amendment's Due Process Clause fully incorporated all provisions of the Bill of Rights against the states. Justice Hugo Black was this view's most famous proponent.
• Selective Incorporation: The view that ultimately prevailed. It holds that the Due Process Clause incorporates only those rights in the Bill of Rights that are fundamental to ordered liberty and deeply rooted in the nation's history and tradition. The Court examines each right individually, case-by-case.

The process of selective incorporation follows a pattern. First, a case arises where a state law or action allegedly violates a provision of the Bill of Rights. The Supreme Court must then decide if that specific right is "fundamental." If it is, the right is incorporated through the Fourteenth Amendment's Due Process Clause and applied to the states. This creates a national floor of rights; states can provide more protection through their own constitutions but cannot provide less.

Landmark Cases of Incorporation: A Required Knowledge Timeline

The doctrine developed gradually over the 20th century, with a major wave occurring during the Warren Court (1953-1969). Key cases you must know include:

• First Amendment Incorporation: Most First Amendment rights were incorporated early. Gitlow v. New York (1925) began the process by assuming freedom of speech and press were incorporated, then applying them to the states. This "assumption" was later made explicit, and rights like religion (Everson v. Board, 1947) and assembly (DeJonge v. Oregon, 1937) followed.
• Gideon v. Wainwright (1963): This is a quintessential incorporation case. Clarence Gideon was charged with a felony in Florida and denied a lawyer because state law only provided counsel for capital offenses. He appealed, arguing his Sixth Amendment right to counsel was fundamental. The Supreme Court agreed, unanimously incorporating the right to counsel in felony cases. The Court stated that a fair trial without counsel for an indigent defendant was impossible, calling it "an obvious truth."
• Tinker v. Des Moines (1969): While primarily a First Amendment case defining student speech rights, Tinker also reinforces the reality of incorporation. The case occurred in a public school, a state entity. The Court's ruling that students do not "shed their constitutional rights to freedom of speech or expression at the schoolhouse gate" explicitly applied the incorporated First Amendment to the actions of local school officials.
• McDonald v. Chicago (2010): A modern example that shows the doctrine is still active. After incorporating the Second Amendment's individual right to bear arms against the states in District of Columbia v. Heller (2008), the Court faced the same question regarding state and local laws. In McDonald, the Court incorporated the Second Amendment right to keep and bear arms for self-defense via the Due Process Clause. This case highlights the ongoing, case-by-case nature of selective incorporation.

The Impact and Modern Debate

Today, nearly all provisions of the Bill of Rights have been incorporated. Notable exceptions include the Third Amendment's quartering of soldiers and the Fifth Amendment's right to a grand jury indictment. The Incorporation Doctrine has fundamentally reshaped American law, ensuring a baseline of individual liberty that applies uniformly across all 50 states.

The modern constitutional debate often centers not on whether a right is incorporated, but on the scope of that incorporated right. For example, while the Second Amendment is incorporated (McDonald), intense litigation continues over what types of gun regulations are permissible. Similarly, while the First Amendment is incorporated, debates rage over its limits in the digital public square. The doctrine nationalized the debate over rights, moving it firmly to the Supreme Court's docket.

Common Pitfalls

1. Confusing "Incorporated" with "Created": The doctrine does not create new rights. It applies existing rights from the Bill of Rights to a new level of government (the states). The right existed at the federal level since 1791; incorporation made it enforceable against states after 1868.
2. Overlooking the Slaughter-House Cases: It's easy to jump from the Fourteenth Amendment to the Due Process Clause. The crippling of the Privileges or Immunities Clause in 1873 is a critical historical turn. Many scholars believe the Court misinterpreted it, and some modern justices have expressed interest in reviving it.
3. Assuming Instant, Total Application: Incorporation was a slow, piecemeal process spanning more than a century. Not all rights were incorporated at once. You must be able to place key cases (Gitlow, Gideon, McDonald) on a timeline to show the doctrine's evolution.
4. Mixing Up "Incorporation" and "Application": Incorporation is the process of making a right applicable to the states. Once incorporated, the Court must still decide how that right applies in specific situations (e.g., Tinker defined how the incorporated First Amendment applies in public schools).

Summary

• The Incorporation Doctrine is the legal process through which most provisions of the Bill of Rights have been applied to state and local governments via the Fourteenth Amendment's Due Process Clause.
• Selective Incorporation, the prevailing method, requires the Supreme Court to determine on a case-by-case basis whether a right is "fundamental to ordered liberty" before applying it to the states.
• Landmark cases like Gideon v. Wainwright (Sixth Amendment right to counsel) and McDonald v. Chicago (Second Amendment right to bear arms) are modern examples of this selective, fundamental-rights analysis.
• The earlier Slaughter-House Cases effectively shut down the Privileges or Immunities Clause as a path for incorporation, directing the Court toward the Due Process Clause.
• This doctrine has nationalized fundamental freedoms, creating a uniform floor of constitutional rights across the United States and making the Supreme Court the primary arbiter of their scope against all levels of government.
