Selective Incorporation Began: Key Moment in American Constitutional Law

Legal Guide Team

Selective incorporation refers to the process by which the U.S. Supreme Court gradually applied portions of the Bill of Rights to state governments through the Due Process Clause of the Fourteenth Amendment. The journey began in the early 20th century and unfolded through a series of landmark decisions, fundamentally shaping American civil liberties. This article explains when selective incorporation began, the pivotal cases, and how the doctrine evolved to influence rights protections across states.

Background: The Bill Of Rights And The States

Originally, the Bill of Rights constrained the federal government, not the states. Barron v. Baltimore (1833) established that the Bill of Rights did not automatically restrain state action. As the United States grew, citizens pressed for uniform protections against state abuses. The Fourteenth Amendment, ratified in 1868, offered a vehicle for extending constitutional safeguards to state governments, though the courts took decades to interpret its scope. The central question became whether fundamental rights embedded in the Bill of Rights could be applied to state laws and practices.

First Moment: The Beginning Of Selective Incorporation

The contemporary era of selective incorporation began in the 1920s, culminating in the pivotal question of whether the federal rights could bind the states via the Fourteenth Amendment. The Supreme Court initiated this process in the mid-1920s, signaling a shift in constitutional doctrine. The term selective incorporation describes the gradual, case-by-case incorporation of individual rights, rather than a blanket adoption of the entire Bill of Rights at once.

Gitlow Vs. New York (1925): The Landmark Beginning

Gitlow v. New York (1925) is widely regarded as the formal starting point for selective incorporation. The Court held that the First Amendment’s free speech protection could be applied to state governments through the Due Process Clause of the Fourteenth Amendment. While Gitlow did not strike down New York’s criminal anarchy statute, it established that the Fourteenth Amendment’s protections could limit state actions. This decision essentially inaugurated the doctrine of selective incorporation, laying the groundwork for applying other Bill of Rights provisions to the states over subsequent decades.

Development Of The Doctrine

After Gitlow, the Supreme Court began a methodical, case-by-case approach to incorporation. The Court assessed which rights were fundamental and thus enforceable against the states. Several guiding principles emerged:

  • Fundamental Rights: Rights considered essential to due process and a fair system of justice were more likely to be incorporated.
  • Nationwide Standards: Incorporation served to harmonize liberty protections across all states, reducing disparities in civil rights.
  • Selective Application: Not all provisions of the Bill of Rights were incorporated immediately or uniformly; some rights were incorporated piecemeal over time.

Key cases built on Gitlow’s framework, expanding or limiting incorporation based on the nature of the right and the specific constitutional clause involved. The Court also considered whether incorporation was appropriate through the Due Process Clause or other constitutional mechanisms.

Notable Milestones In The Incorporation Process

The subsequent decades produced numerous landmark decisions that broadened or clarified the scope of incorporation. Some of the most influential include:

  • Mapp v. Ohio (1961): Extended the exclusionary rule to the states, prohibiting evidence obtained unlawfully from being used in state courts.
  • Gideon v. Wainwright (1963): Guaranteed the right to counsel for defendants in state court who cannot afford an attorney.
  • Miranda v. Arizona (1966): Required police to inform suspects of their rights, affecting state law enforcement practices.
  • Katz v. United States (1967): Adopted a broader interpretation of the Fourth Amendment, influencing state surveillance law.
  • Prospective And Retroactive Effects: Courts carefully balanced when to apply incorporation to ongoing cases or new prosecutions, shaping procedural protections across jurisdictions.

Current Landscape: How Incorporation Shapes Modern Rights

Today, the doctrine of selective incorporation continues to influence a broad array of rights. The Supreme Court has incorporated most—but not all—of the First, Fourth, Fifth, Sixth, and Eighth Amendment protections against state action. Some entrenched rights, or the manner of their application, remain subjects of scholarly debate and judicial interpretation. The decision to apply or limit particular rights often depends on evolving social norms, technological changes, and procedural concerns within state systems.

Key Takeaways: When And How It Began

When did selective incorporation begin? The process began in the 1920s, with the seminal ruling in Gitlow v. New York (1925) establishing that the Fourteenth Amendment can bind the states to certain First Amendment protections. This case marked the formal start of applying the Bill of Rights to state governments, a process that would unfold incrementally over the following decades.

Why does it matter? Incorporation ensures a baseline of constitutional rights across all states, preventing states from adopting laws or practices that would infringe fundamental liberties guaranteed by the Bill of Rights.

How has it evolved? Through a steady line of landmark cases, the Court identified which rights are fundamental and how their application should be integrated with state law and procedure. The result is a nuanced framework that protects individual liberties while accommodating state sovereignty where appropriate.
