# District of Columbia v. Heller

Heller established for the first time that the Second Amendment protects an individual right to possess firearms for traditionally lawful purposes, such as self-defense within the home, independent of service in a militia. The decision struck down the District of Columbia's handgun ban and trigger lock requirement, fundamentally reshaping Second Amendment jurisprudence.

## Citation

554 U.S. 570 (2008)

## Year

2008

## Court

Supreme Court of the United States

## Facts

The District of Columbia effectively banned the possession of handguns by making it illegal to carry an unregistered firearm and prohibiting the registration of handguns. The law also required residents to keep their lawfully owned firearms, such as registered long guns, unloaded and disassembled or bound by a trigger lock at all times. Dick Heller, a D.C. special police officer authorized to carry a handgun while on duty, applied for a registration certificate for a handgun he wished to keep at home for self-defense. His application was denied.

## Procedural History

Heller filed suit in the U.S. District Court for the District of Columbia. The district court dismissed the complaint. The D.C. Circuit reversed, holding the Second Amendment protects an individual right. The Supreme Court granted certiorari.

## Issue

Does the Second Amendment protect an individual right to keep and bear arms unconnected with service in a militia, and does the District of Columbia's handgun ban violate that right?

## Holding

The Court held 5-4 that the Second Amendment protects an individual right to possess a firearm unconnected with service in a militia and to use that arm for traditionally lawful purposes, such as self-defense within the home. The D.C. handgun ban and trigger lock requirement were unconstitutional because they effectively prohibited an entire class of arms that Americans overwhelmingly choose for the lawful purpose of self-defense.

## Reasoning

Justice Scalia's majority opinion conducted an extensive textual and historical analysis of the Second Amendment. The Court parsed the Amendment's prefatory clause ('A well regulated Militia, being necessary to the security of a free State') and operative clause ('the right of the people to keep and bear Arms, shall not be infringed') separately. Scalia held that the prefatory clause announces a purpose but does not limit the operative clause's protection of an individual right. Through detailed historical analysis, the Court concluded that the right to keep and bear arms was understood at the founding as an individual right predating the Constitution. However, the right is not unlimited: the Court noted that longstanding prohibitions on possession by felons and the mentally ill, laws forbidding firearms in sensitive places, and conditions on commercial sale of arms are presumptively lawful.

## Dissent

Justice Stevens dissented, arguing that the Second Amendment protects only a militia-related right to bear arms and that the majority's individual rights interpretation is unsupported by the text, history, and precedent. Justice Breyer also dissented, arguing that even if the Amendment protects an individual right, the D.C. restrictions were permissible under an interest-balancing approach, which the majority expressly rejected.

## Impact

Heller transformed Second Amendment law from a collective right associated with militia service into an individual right of constitutional magnitude. The decision was extended to state and local governments through McDonald v. City of Chicago in 2010. In New York State Rifle & Pistol Association v. Bruen (2022), the Court further developed Heller's framework, requiring gun regulations to be consistent with the nation's historical tradition of firearm regulation. Heller has generated extensive litigation over the constitutionality of various firearms regulations.

## Key Quotes

- The Second Amendment protects an individual right to possess a firearm unconnected with service in a militia, and to use that arm for traditionally lawful purposes, such as self-defense within the home.
- Like most rights, the right secured by the Second Amendment is not unlimited.
- The enshrinement of constitutional rights necessarily takes certain policy choices off the table. These include the absolute prohibition of handguns held and used for self-defense in the home.

## Exam Relevance

Heller is the foundational case for any Second Amendment exam question. Professors test students on the individual versus collective rights debate, the relationship between the prefatory and operative clauses, and the scope of permissible regulations. After Bruen, students should understand the historical tradition test that has replaced means-end scrutiny for evaluating gun regulations.

## Study Tips

- Understand the textual analysis: the relationship between the prefatory clause and the operative clause.
- Know the list of presumptively lawful regulations Scalia identified (felon-in-possession, sensitive places, commercial sale conditions).
- Be prepared to compare the majority's originalist methodology with the dissenters' approaches.
- Trace the doctrinal development from Heller through McDonald (incorporation) to Bruen (historical tradition test).

## Doctrine Established

Individual Right to Bear Arms
