The Constitution protects more than the freedoms it names on the page. Rights not listed in the Constitution, sometimes called unenumerated rights, are freedoms the Supreme Court has recognized as protected even though no specific clause spells them out. They include the right to privacy, the right to marry, the right to travel between states, parental authority over children’s upbringing, private intimate conduct between consenting adults, and the right to refuse unwanted medical treatment. The Ninth Amendment supplies the principle that such rights exist; the Fifth and Fourteenth Amendments’ Due Process Clauses are the doctrinal tools courts use to enforce them.
What the Ninth Amendment Actually Does
The Ninth Amendment, ratified in 1791, states: “The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.”1Constitution Annotated. Ninth Amendment It does not create or identify any particular right. It functions as a rule of construction, instructing courts that the Bill of Rights is a floor rather than a ceiling. The freedoms singled out in the first eight amendments do not imply that everything left off the list is fair game for government control.2Cornell Law School / Legal Information Institute. Historical Background on the Ninth Amendment
Because the Ninth Amendment doesn’t name anything, courts rarely rest a decision on it alone. The actual enforcement work happens elsewhere.
How Courts Recognize an Unlisted Right
Both the Fifth and Fourteenth Amendments forbid the government from taking away a person’s “life, liberty, or property, without due process of law.”3Constitution Annotated. Amdt5.5.1 Overview of Due Process The Fifth applies to the federal government; the Fourteenth, ratified in 1868, extends the same limit to every state.4Constitution Annotated. Fourteenth Amendment Courts have read the word “liberty” in those clauses to protect more than freedom from physical confinement. That reading is called substantive due process, and it’s the doctrine used when someone argues that the Constitution protects a freedom the text never names.
Not every asserted freedom qualifies. In Washington v. Glucksberg (1997), the Supreme Court set out the test still used today. A claimed right must be “deeply rooted in this Nation’s history and tradition” and “implicit in the concept of ordered liberty,” and the party asserting it must describe the right carefully rather than in sweeping terms.5Justia U.S. Supreme Court Center. Washington v. Glucksberg, 521 U.S. 702 How the right is framed often decides the case.
Which Unlisted Rights Are Currently Recognized
Privacy
The word “privacy” appears nowhere in the Constitution. In Griswold v. Connecticut (1965), the Supreme Court struck down a state ban on married couples using contraceptives, reasoning that several provisions of the Bill of Rights, including the First, Third, Fourth, and Fifth Amendments, cast “penumbras” that together shelter intimate decisions from government intrusion.6Justia U.S. Supreme Court Center. Griswold v. Connecticut, 381 U.S. 479 Later cases shifted the anchor to the Fourteenth Amendment’s liberty interest, but the core idea held: the government cannot dictate a person’s most personal choices without a powerful reason.
Private Intimate Conduct
In Lawrence v. Texas (2003), the Court struck down a state law criminalizing consensual sexual conduct between same-sex partners, holding that the Due Process Clause protects private choices about intimate relationships. As the Court put it, “The State cannot demean their existence or control their destiny by making their private sexual conduct a crime.”7Justia U.S. Supreme Court Center. Lawrence v. Texas, 539 U.S. 558
Marriage
In Obergefell v. Hodges (2015), the Court held that the fundamental right to marry extends to same-sex couples under the Fourteenth Amendment’s Due Process and Equal Protection Clauses, treating marriage as central enough to individual dignity and autonomy that states cannot reserve it for opposite-sex couples.4Constitution Annotated. Fourteenth Amendment
Interstate Travel
No clause explicitly grants the right to move freely between states, but courts have treated it as fundamental for generations. In Shapiro v. Thompson (1969), the Court described it as “a right so elementary [it] was conceived from the beginning to be a necessary concomitant of the stronger Union the Constitution created.”8Justia U.S. Supreme Court Center. Shapiro v. Thompson, 394 U.S. 618 Saenz v. Roe (1999) later identified three components: the right to enter and leave any state, the right to be treated as a welcome visitor while passing through, and the right to equal treatment if you become a permanent resident.9Law.Cornell.Edu. Saenz v. Roe
Parental Authority
The right of parents to direct their children’s upbringing and education has been recognized as a fundamental liberty interest since the 1920s, in cases including Meyer v. Nebraska (1923) and Pierce v. Society of Sisters (1925). Troxel v. Granville (2000) reinforced the presumption that fit parents act in their children’s best interests, holding that a state court violated a mother’s rights by overriding her visitation decisions without proper weight for her judgment.10Justia U.S. Supreme Court Center. Troxel v. Granville, 530 U.S. 57
Refusing Medical Treatment
In Cruzan v. Director, Missouri Department of Health (1990), the Court recognized that a competent person has a constitutionally protected liberty interest in refusing unwanted medical treatment, including life-sustaining measures like hydration and nutrition. States can impose procedural safeguards, but the underlying right flows from the Due Process Clause.11Law.Cornell.Edu. Cruzan v. Director, Missouri Department of Health, 497 U.S. 261
What Dobbs Changed
For nearly fifty years, abortion was treated as another branch of the privacy and liberty rights recognized in Griswold and its successors. In Dobbs v. Jackson Women’s Health Organization (2022), the Supreme Court overruled that precedent, holding that abortion is “not deeply rooted in the Nation’s history and tradition” and therefore not protected under the Fourteenth Amendment. The Court pointed to the fact that three-quarters of states had criminalized abortion by the time the Fourteenth Amendment was adopted in 1868.12Supreme Court of the United States. Dobbs v. Jackson Women’s Health Organization
The majority distinguished abortion from other unlisted rights, calling it “critically different” because it involves what the law may characterize as potential life. It reaffirmed the history-focused Glucksberg test as controlling and rejected broader reasoning about autonomy or evolving norms.13Constitution Annotated. Amdt14.S1.6.3.1 Overview of Noneconomic Substantive Due Process Justice Thomas, in a solo concurrence, urged the Court to “reconsider all of this Court’s substantive due process precedents,” naming Griswold, Lawrence, and Obergefell.12Supreme Court of the United States. Dobbs v. Jackson Women’s Health Organization No other justice joined that view, but the concurrence made clear that at least one member of the Court sees the entire category as open to challenge.
These Rights Aren’t Absolute
Even a recognized fundamental right can be regulated. What matters is the level of judicial scrutiny.
When a law restricts a fundamental right, courts apply strict scrutiny. The government must show that the law serves a compelling interest and is narrowly tailored to that interest without sweeping more broadly than necessary.13Constitution Annotated. Amdt14.S1.6.3.1 Overview of Noneconomic Substantive Due Process Most laws fail this test. If a claimed right is not deemed fundamental, courts apply rational basis review, and the government need only show a reasonable connection between the law and a legitimate purpose. Most laws survive that standard. So whether a right is classified as fundamental often decides the case.
State Constitutions Can Protect More
Federal rights are a floor. State constitutions can offer broader protection, and roughly 33 states have their own version of the Ninth Amendment, sometimes called a “Baby Ninth,” with language reserving unlisted rights to the people. State supreme courts interpret these provisions independently of federal precedent, so a right the U.S. Supreme Court declines to recognize may still be protected under state law.
This matters more since Dobbs. When the federal floor drops, state constitutions become the primary line of defense for rights previously protected nationally. Some state supreme courts have gone beyond federal precedent on privacy and intimate conduct, grounding decisions in state constitutional text rather than federal substantive due process.
Suing When an Unlisted Right Is Violated
If a state or local government infringes on a constitutionally protected right, the main federal remedy is a lawsuit under 42 U.S.C. § 1983. That statute lets any person sue a government official who, acting in an official capacity, deprives them of “any rights, privileges, or immunities secured by the Constitution and laws.”14Office of the Law Revision Counsel. 42 U.S. Code 1983 – Civil Action for Deprivation of Rights It covers both listed and unlisted rights. A successful plaintiff can obtain injunctive relief, money damages, or both.
If you win, a federal court has discretion to award reasonable attorney’s fees under 42 U.S.C. § 1988(b), and prevailing plaintiffs are ordinarily entitled to that award.15GovInfo. 42 USC 1988 – Proceedings in Vindication of Civil Rights That fee-shifting rule exists because many constitutional rights cases involve dignitary or liberty interests rather than large dollar amounts. Federal filing fees run a few hundred dollars, and courts can waive them entirely for people who cannot afford them.
The practical picture is this: the scope of your unlisted constitutional rights depends on both federal doctrine and the state where you live, and it can shift with the composition of the courts. Rights that seemed settled for decades can be reconsidered, as Dobbs showed. Reading both the federal and state protections that apply to your situation gives you the clearest sense of where you actually stand.
