What does the 14th Amendment say about guns? A clear legal explainer

How the Fourteenth Amendment makes the bill of rights right to bear arms apply to states

Text of the Fourteenth Amendment and why it matters

The Fourteenth Amendment, ratified in 1868, provides the constitutional mechanism by which many provisions of the Bill of Rights can be applied to state and local governments through a process known as incorporation. The amendment’s text and ratification date are preserved in the National Archives, which hosts the official record of the amendments to the Constitution as ratified by the states National Archives.

Incorporation explained in plain language

Incorporation is a legal doctrine courts use to decide whether a protection in the Bill of Rights limits state as well as federal power. At its core, incorporation means that a right originally written as protection against the federal government can, in certain cases, be read to constrain state and local law too. A clear overview of the doctrine and how courts have treated it is available from a neutral legal reference that explains the incorporation framework and its modern contours Legal Information Institute and from related coverage on this site constitutional rights.

In everyday terms, incorporation does not automatically make every federal right enforceable in the same way against states. Instead, it gives federal courts a constitutional path to review state conduct under the standards set by Supreme Court precedent. That means asking whether a particular right is recognized as fundamental enough, or whether a specific constitutional clause has been interpreted to reach state action.

The legal mechanism of incorporation is procedural and interpretive, not a policy prescription. Courts perform legal analysis; they do not make policy choices for legislatures. Where incorporation applies, it creates a litigation route for people who challenge state or local rules under federal constitutional standards.

McDonald v. City of Chicago and the bill of rights right to bear arms

What the Court decided in McDonald

The Supreme Court in McDonald v. City of Chicago held that the Second Amendment right to keep and bear arms is incorporated against the states. The Court’s opinion explains that the Second Amendment is a right that is sufficiently connected to the concept of ordered liberty to be applied through the Fourteenth Amendment, and the opinion is available from the Supreme Court’s official site for direct review McDonald v. City of Chicago opinion.

What incorporation of the Second Amendment meant for state and local rules

Practically, McDonald meant that state and local firearms laws could be challenged in federal court on Second Amendment grounds. Before McDonald, the Second Amendment was widely understood to restrict only federal actors; after McDonald, the amendment’s protections could be invoked against states and municipalities through the Fourteenth Amendment. A concise case summary and accessible commentary on the decision can be found at a neutral case resource that explains the opinion and its implications Oyez case summary.

McDonald did not prescribe a single test for how to evaluate every firearms regulation under the Second Amendment. Instead, it resolved the incorporation question for the Second Amendment and left lower courts to apply the appropriate standards when addressing specific kinds of regulations under later precedent.

Bruen and the new historical-tradition test for Second Amendment review

What the Supreme Court held in Bruen

In 2022, the Supreme Court in New York State Rifle & Pistol Association v. Bruen changed the way courts evaluate many Second Amendment challenges by instructing that courts must assess firearm regulations against the historical tradition of firearm regulation in the United States. The full opinion sets out the Court’s reasoning and the new framework for analysis New York State Rifle & Pistol Association v. Bruen opinion.

How Bruen replaced means-end scrutiny with a history-focused inquiry

Before Bruen, many courts applied a means-end approach that weighed government interests against the burden a rule placed on a person’s right. Bruen rejected that framework for many Second Amendment claims, directing courts to determine whether a challenged regulation is consistent with historical tradition. This shift changes the question from whether a law is an effective or necessary means to achieve public purposes to whether there is a historical analogue that justifies the regulation under the Nation’s tradition of firearm regulation.

That new historical approach has important practical consequences. It requires judges to study historical materials and to make comparative judgments about whether modern regulations are sufficiently similar to historical measures that were accepted at the time of the founding or in important later periods. Legal analysts and public interest centers have produced guidance and summaries to help practitioners and courts apply the Bruen framework in modern cases Brennan Center analysis.

How federal courts use the Fourteenth Amendment to review state and local gun laws

The incorporation link between the Second Amendment and the Fourteenth Amendment

Because the Fourteenth Amendment is the vehicle for incorporation, federal courts use it to apply the incorporated Second Amendment against states and localities. When a plaintiff challenges a state or local firearm regulation on constitutional grounds, the federal court reviews the claim under the governing Supreme Court precedent, including the incorporation holding in McDonald and the analytic framework set out in Bruen. The underlying amendment text and its role in incorporation are recorded in the National Archives National Archives.

How courts invalidate or uphold state laws in practice

Federal courts resolve challenges by comparing the challenged rule to controlling precedent and by applying the relevant test. After Bruen, courts ask whether the regulation is consistent with the historical tradition; if a court concludes it is not, the rule can be struck down as inconsistent with the incorporated Second Amendment. Remedies in constitutional cases commonly include injunctions or declaratory judgments that prevent enforcement of a law while the legal dispute proceeds.

Outcomes turn on both legal framing and factual record. How courts describe the historical analogues, how they frame the regulated activity, and the evidence they find persuasive all shape decisions. The interaction of incorporation with subsequent precedent means lower courts play a central role in how doctrine develops on the ground.

Open questions: background checks, permitting, sensitive places and weapon-specific rules under Bruen

Why modern regulatory categories raise new questions

Bruen’s historical inquiry leaves open difficult questions about several modern regulatory categories. Background-check regimes (see reporting on ammunition background checks CalMatters), permitting systems, rules limiting firearms in sensitive places, and bans or restrictions on particular weapons are all subjects where courts must decide whether an historical analogue exists and whether the comparison is apt. Observers and legal trackers note that these categories present both factual and methodological challenges as courts try to map modern regulations onto historical tradition Bruen opinion.

How courts are treating background checks and permitting

Courts reviewing background checks and permitting systems under Bruen have divided on whether those modern regulatory tools resemble historical measures that regulated who could possess arms. Some decisions have found sufficient historical analogues, while others have concluded the fit is weak and have invalidated rules as inconsistent with the historical tradition. Commentators emphasize that outcomes vary by jurisdiction and by how courts frame the question Brennan Center analysis (see a Ninth Circuit decision Rhode v. Bonta).

Sensitive-place rules and weapon-specific bans under current doctrine

Sensitive-place restrictions are another unsettled area. Courts must decide what counts as a protected right within the Second Amendment and whether longstanding prohibitions for specific locations have historical counterparts. Similarly, weapon-specific limits require courts to locate historical parallels or to find that certain arms were treated differently in historical practice. Legal trackers report uneven rulings as lower courts apply the Bruen historical test to these categories Brennan Center analysis.

Recent lower-court examples and what they show in practice

Examples of varied rulings across jurisdictions

Since Bruen, lower courts have produced different results when considering licensing, place-based restrictions, and weapon-specific rules. Some courts have upheld regulations by finding historical analogues, while others have invalidated rules for lack of such analogues. Legal overviews and trackers document these divergent outcomes and provide summaries of the principal cases and trends Legal Information Institute (see a dataset of Bruen-based decisions Court Decisions Based on Bruen).

How the historical test is applied in different factual contexts

Application of the historical test often depends on how a court characterizes the regulated conduct, the precision of historical evidence, and the mapping the court creates between past measures and present-day rules. In practice, judges look at different kinds of historical sources and draw distinctions among regulatory aims and mechanisms, which helps explain why similar modern rules can receive different treatment in different courts.

Common misunderstandings and pitfalls when reading about the 14th Amendment and guns

Mistaking incorporation for an absolute, unlimited right

A common error is to treat incorporation as making the Second Amendment absolute in all circumstances. Incorporation gives rights a route to be applied to states, but courts still interpret the scope and limits of those rights under governing precedent. McDonald incorporated the Second Amendment, but it did not state that all regulations are unconstitutional in every circumstance McDonald opinion.

Overreading Bruen as resolving all modern regulatory questions

Another pitfall is assuming Bruen resolved every open question about modern gun rules. Bruen changed the analytical framework, but it left many concrete regulatory categories to lower courts for application. As a result, doctrine is evolving and readers should avoid claims that Bruen provides definitive answers for each type of modern regulation Bruen opinion.

How to follow developments and consult primary sources

Primary documents: amendments and Court opinions

To verify doctrine, consult primary documents: the Fourteenth Amendment text at the National Archives and Supreme Court opinions such as McDonald and Bruen on the Court’s website. Reading the original opinions helps readers see the legal reasoning courts use to reach their conclusions National Archives.

Trusted legal trackers and explainers to watch

Reputable legal centers and trackers provide summaries and ongoing case lists that make it easier to follow how courts apply Bruen and McDonald. These resources do not replace reading primary opinions, but they frequently flag important cases and provide context that helps interpret lower-court trends Brennan Center analysis.

Takeaways: what to remember about the Fourteenth Amendment and firearms

Remember that the Fourteenth Amendment is the vehicle courts use to apply the Bill of Rights to state governments, and that McDonald incorporated the Second Amendment so that state and local gun laws can be challenged in federal court McDonald opinion.

Also keep in mind that Bruen replaced means-end scrutiny with a historical-tradition test, and that has produced uneven lower-court outcomes as judges apply the new framework to modern regulations. For current status in any jurisdiction, consult primary opinions and trusted trackers.
