What does the 14th Amendment have to do with privacy? An accessible guide

Quick overview: why the Fourteenth Amendment matters for privacy

What this article explains, bill of rights right to privacy

The central legal route for many privacy claims is the Fourteenth Amendment, specifically its Due Process Clause, which courts have used to make certain rights enforceable against the states and to protect some unenumerated liberties. For a concise description of the Amendment and its text, see the Legal Information Institute on the Fourteenth Amendment Legal Information Institute on the Fourteenth Amendment.

This article breaks the topic into clear parts: what we mean by constitutional privacy, how incorporation and substantive due process work, the key Supreme Court decisions that shaped the doctrine, how Dobbs changed the landscape for abortion-related privacy claims, and practical effects for contraception, assisted reproduction, and data protections. Readers will find short, source-linked summaries and a checklist to evaluate public claims.

The aim is neutral explanation, not advocacy. The account relies on Supreme Court opinions and prominent analyses where appropriate. Where doctrine is unsettled after Dobbs, I explain the debate and point to state law as an important venue for protections.

How to read the rest of the piece

Start with the definitions section if you want the basic legal terms. Move to the doctrinal framework to see how courts treat different claims. Read case summaries to connect doctrine to decisions, and the later sections for practical scenarios and a short checklist for evaluating claims.

This opening overview points readers to primary opinions and to ongoing analysis after Dobbs, and it flags that some questions are now resolved by state law rather than a single federal privacy right.

What do we mean by privacy under the Constitution?

Two senses of constitutional privacy: incorporated Bill of Rights protections and unenumerated liberties

One common meaning of constitutional privacy is incorporation, the process by which the Fourteenth Amendment makes certain protections in the Bill of Rights enforceable against state governments. Courts have long treated incorporation as a route to apply specific, enumerated rights to the states, and that framing shapes how judges analyze claims about search, speech, and religious liberty. For background on incorporation and the Fourteenth Amendment, see the Legal Information Institute on the Fourteenth Amendment Legal Information Institute on the Fourteenth Amendment.

The other important meaning is substantive due process, a doctrine that recognizes certain unenumerated liberties as protected by the Fourteenth Amendment’s guarantee of liberty. Under this view, some intimate decisions, marital choices, and personal autonomy interests can be protected even if they are not spelled out in the text of the Bill of Rights.

How courts describe ‘liberty’ under the Due Process Clause

When courts analyze liberty under the Due Process Clause, they ask whether the interest at stake is historically rooted, central to individual autonomy, or otherwise fundamental in the Court’s precedent. That approach appears across opinions that recognize privacy-related protections and helps explain why some claims succeed as substantive rights while others are treated differently. For an accessible description of how courts use the Due Process Clause, consult the Legal Information Institute on the Fourteenth Amendment Legal Information Institute on the Fourteenth Amendment.

These two senses of privacy, incorporation and substantive due process, are not always exclusive. In some cases a claim can be analyzed under both frameworks, and courts choose the approach that fits the right and the remedy sought.

How the Fourteenth Amendment has been used to protect privacy: a doctrinal framework

Incorporation: applying specific Bill of Rights protections to the states

Incorporation treats the Fourteenth Amendment as the vehicle that binds states to selected protections in the Bill of Rights. For example, elements of the Fourth Amendment and other protections have been applied to states through this route, which gives plaintiffs a concrete doctrinal path when an enumerated right is at issue. See the Legal Information Institute on the Fourteenth Amendment for background on incorporation doctrine Legal Information Institute on the Fourteenth Amendment.

Focus term use: The phrase bill of rights right to privacy appears here to show how some privacy claims are framed as extensions of enumerated protections, such as search and seizure rules or protections against compelled testimonial abuse. That framing matters for remedies and how courts write opinions.

Substantive due process: recognizing certain liberty interests

Substantive due process is the doctrinal route courts use to recognize some rights that are not explicitly in the Bill of Rights but are treated as fundamental to liberty. Historic cases that protected marital privacy and intimate conduct used this analysis, which asks whether the asserted right is part of the liberty protected by the Fourteenth Amendment. For an original opinion applying substantive due process to privacy claims, see Griswold v. Connecticut Griswold v. Connecticut, opinion text.

Courts weigh several factors when deciding whether to recognize a right under substantive due process, including precedent, historical practice, and whether the interest is central to personal autonomy. Those factors influence whether a court will extend protections to a new context.

When courts choose one approach over the other

Judges consider the nature of the right, the available precedent, and the practical remedies requested. If a claim fits neatly under a specific constitutional clause, incorporation may be the preferred path. If a claim involves personal autonomy without an obvious textual hook, courts may turn to substantive due process. The choice affects legal standards and the kinds of judicial remedies available. For discussion of these doctrinal differences, see the Legal Information Institute on the Fourteenth Amendment Legal Information Institute on the Fourteenth Amendment.

That doctrinal choice matters in practice. Different frameworks produce different tests, and those tests shape litigation strategy and the odds of success in lower courts.

Key Supreme Court cases that shaped privacy doctrine

Griswold v. Connecticut and marital privacy

Griswold v. Connecticut (1965) is the foundational Supreme Court decision recognizing a constitutional right to marital privacy in the context of contraception, and it used substantive due process reasoning to protect intimate choices from state intrusion. The opinion is frequently cited as an early source for privacy jurisprudence; read the opinion text in Griswold v. Connecticut Griswold v. Connecticut.

Griswold established principles that later cases cited when protecting private conduct or family choices, and it remains a touchstone in litigation over privacy-related claims.

Lawrence v. Texas on intimate conduct

Lawrence v. Texas (2003) applied Fourteenth Amendment liberty principles to protect consensual intimate conduct between adults. The decision built on earlier privacy precedents to reject laws that criminalized private sexual conduct between consenting adults. For the Court’s reasoning in Lawrence, see Lawrence v. Texas Lawrence v. Texas.

Lawrence influenced subsequent litigation on the scope of intimate liberty and provided doctrinal support for later decisions on marriage equality.

Obergefell v. Hodges and marriage equality

Obergefell v. Hodges (2015) held that same-sex couples have a constitutional right to marry under the Fourteenth Amendment, applying liberty and equal protection principles to marriage. The decision relied on precedents recognizing intimate and family liberties under the Due Process Clause. For the full opinion, see Obergefell v. Hodges Obergefell v. Hodges.

Obergefell is often cited alongside Griswold and Lawrence to show how the Court has approached personal autonomy and family choices under the Fourteenth Amendment.

Dobbs v. Jackson Women’s Health Organization and its effect on abortion privacy claims

Dobbs v. Jackson Women’s Health Organization (2022) overruled Roe and held that the Constitution does not confer a federal constitutional right to abortion, which substantially changed the treatment of abortion within the federal privacy framework. The decision is the starting point for understanding contemporary disputes over abortion and related privacy questions; see the Dobbs majority opinion Dobbs majority opinion.

Although Dobbs removed Roe’s federal protection for abortion, earlier precedents like Griswold, Lawrence, and Obergefell remain cited in litigation, and courts continue to apply those precedents in contexts that do not directly involve abortion.

The post-Dobbs landscape: what changed and what remains unsettled

Dobbs’ direct holding is narrow in subject matter, but the opinion generated doctrinal debate about the reach of substantive due process and what limits, if any, the decision might imply for other privacy precedents. Scholars and court decisions have discussed whether Dobbs signals broader limits on substantive due process, and that debate remains active in legal commentary. For analysis on the future of substantive due process after Dobbs, see SCOTUSblog analysis SCOTUSblog analysis, and related commentary at CSIS What Privacy in the United States Could Look Like without Roe.

Because Dobbs removed a federal constitutional right to abortion, many abortion-related questions moved to state constitutions, statutes, and administrative law. That shift means state courts and legislatures play a larger role in determining protections related to reproductive health.

Observers note uncertainty about how lower courts will reconcile Dobbs with earlier privacy cases in specific situations such as contraception, assisted reproduction, and data privacy. Some courts and scholars treat those precedents as intact, while others debate the doctrinal implications of Dobbs. See the Dobbs opinion for the primary text and reasoning Dobbs majority opinion.

As a practical matter, many privacy questions will be resolved under state constitutions or statutes when the federal route is uncertain or unavailable.

Practical examples: how the Fourteenth Amendment framework affects real issues

Contraception and assisted reproduction

Griswold’s protection of marital privacy informed later cases addressing contraception, and courts often look to that precedent when similar personal medical choices arise. The reasoning in Griswold remains a reference point in litigation over reproductive and family decisions; for the original opinion, see Griswold v. Connecticut Griswold v. Connecticut.

After Dobbs, questions about access to contraception or assisted reproductive technologies may be resolved differently depending on state law. In some states, statutory protections or state constitutional language will decide the outcome, rather than a single federal privacy right.

Intimate conduct and marriage rights

Lawrence and Obergefell illustrate how the Fourteenth Amendment protected intimate conduct and marriage equality under liberty and equal protection reasoning. These cases show that courts have recognized a set of personal autonomy interests under the Due Process Clause, and those precedents continue to be cited in disputes about family law and private conduct. See Lawrence v. Texas for the opinion text Lawrence v. Texas.

Even after Dobbs, courts and litigants still rely on Lawrence and Obergefell in contexts that do not present the same questions as abortion, and those precedents continue to shape litigation about private relationships and family recognition.

Data privacy and state law avenues

Data privacy raises different challenges because the Constitution does not create a single federal ‘privacy’ statute for modern information flows. Many data privacy claims turn on statutory protections, federal statutes, or state constitutional provisions rather than a single Fourteenth Amendment doctrine. For discussion of post-Dobbs avenues and state law importance, see SCOTUSblog analysis SCOTUSblog analysis and the article “Informational Privacy After Dobbs” Informational Privacy After Dobbs (UA Law).

How to evaluate claims about privacy and the 14th Amendment

Here is a short checklist to assess public claims about constitutional privacy:

• Identify whether the claim relies on an incorporated Bill of Rights clause or on substantive due process.
• Check controlling precedent at the Supreme Court level for similar fact patterns.
• Notice whether the question involves state constitutional text or statutes that may provide protection independently.
• Distinguish doctrinal categories because remedies and standards differ.

For readers and journalists, the practical step is to read the controlling opinions and to note whether a case cites incorporation or substantive due process as its basis. Supreme Court opinions remain the primary source for doctrinal explanation, while state constitutions govern where federal protection is removed or narrowed.

When you see claims that Dobbs automatically invalidated other privacy precedents, be cautious. The most reliable approach is to look at how courts frame the specific right and whether the precedent at issue addresses similar liberty interests. For the Dobbs opinion text, see the Dobbs majority opinion Dobbs majority opinion.

Common mistakes, final takeaways, and where to look next

Common errors include assuming that Dobbs nullified precedents like Griswold, or that there is a single federal ‘privacy’ right that covers all issues. Those assumptions oversimplify the law. Griswold, Lawrence, and Obergefell remain precedents cited in litigation, even as Dobbs changed the federal status of abortion-related rights. For Griswold primary text, see Griswold v. Connecticut Griswold v. Connecticut.

Main takeaway: The Fourteenth Amendment is central to modern privacy law both through incorporation and through substantive due process, but post-Dobbs uncertainty means many questions will be decided under state constitutions, statutes, or future federal litigation. For analysis of post-Dobbs doctrinal debates, see SCOTUSblog analysis SCOTUSblog analysis.

Where to look next: read the relevant Supreme Court opinions, consult state constitutional texts when the issue touches state authority, and follow reputable legal summaries for evolving litigation. Primary opinions and neutral commentary are the best starting points for further research. See state constitutional texts and official opinion pages for original sources.
