Unalienable rights are freedoms that belong to every person simply because they exist, not because any government granted them. The Declaration of Independence names three by example: life, liberty, and the pursuit of happiness. In American law, those principles become enforceable through the Bill of Rights, the Due Process Clauses of the Fifth and Fourteenth Amendments, and civil rights statutes that let you sue officials who cross the line.
What Unalienable Rights Are
A right is unalienable when it cannot be taken away, surrendered, or transferred to someone else. The word describes something permanently attached to a person’s humanity rather than something a legislature voted into existence. A government can violate an unalienable right, but the theory holds that it can never legitimately erase it. That distinction flips the usual power dynamic. Instead of citizens having only the freedoms their government permits, the government has only the powers its citizens permit.
You may see the word spelled “inalienable.” The two terms mean the same thing. “Unalienable” was the more common spelling in the eighteenth century and appears in the Declaration of Independence. “Inalienable” gradually replaced it in everyday usage after the 1830s, but both carry identical legal and philosophical weight.
The idea itself predates the United States. Enlightenment thinkers, most influentially John Locke, argued that individuals hold rights in a “state of nature” that do not depend on any ruler’s approval, and that the entire purpose of forming a government is to protect those pre-existing rights. The American founders built their case for independence on that logic: governments derive their power from the consent of the governed, and when a government becomes destructive of the people’s rights, the people may alter or abolish it.1National Archives.

The Rights Named in the Declaration
The Declaration lists three unalienable rights by name: life, liberty, and the pursuit of happiness.1National Archives. Declaration of Independence: A Transcription The text says “among these,” signaling that the three are examples drawn from a larger, open-ended set of inherent rights.
The right to life means the government cannot end your existence without following formal legal procedures. Liberty covers freedom from arbitrary government restraint and the ability to make your own choices without unjustified interference. The pursuit of happiness is the most debated of the three. Thomas Jefferson chose this phrase rather than Locke’s “property,” and historical evidence suggests he drew on the work of Scottish philosopher Henry Home, Lord Kames.2Library of Congress. Index of Documents for Pursuit of Happiness The phrase captures something broader than property ownership: the freedom to choose your own vocation, form relationships, and seek personal fulfillment.
Rights the Constitution Does Not Spell Out
The founders worried that writing specific rights into the Bill of Rights might accidentally suggest those were the only rights people had. The Ninth Amendment addresses that concern directly: “The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.”3Legal Information Institute. Ninth Amendment The list of rights in the Constitution is not exhaustive. The Supreme Court has generally treated the Ninth Amendment as a rule of interpretation rather than a standalone guarantee, but its existence reinforces the idea that unalienable rights extend beyond whatever the text happens to mention.4Legal Information Institute. Overview of Ninth Amendment, Unenumerated Rights
Courts have used a doctrine called substantive due process to identify and protect specific unenumerated rights. Under this approach, the Due Process Clauses of the Fifth and Fourteenth Amendments protect not just fair procedures but also fundamental freedoms that are deeply rooted in American history and tradition. Through substantive due process, the Supreme Court has recognized rights that appear nowhere in the Constitution’s text, including the right to marry, the right to raise your children as you see fit, the right to refuse unwanted medical treatment, and the right to privacy.5Cornell Law School. Substantive Due Process The scope of these rights is not static. Most modern privacy decisions rely on the Fourteenth Amendment’s guarantee of due process, and the 2022 Dobbs decision removed abortion from the category of constitutionally protected privacy rights.6LII / Legal Information Institute.

How the Constitution Enforces These Rights
The Declaration articulates unalienable rights as a philosophical principle. The Constitution is the legal machinery that enforces them. Several provisions work together to limit what the government can do to you.
The Bill of Rights
The first ten amendments restrict the federal government from interfering with specific freedoms: speech, religion, assembly, the press, the right to bear arms, protection against unreasonable searches, the right to a jury trial, and others.7Legal Information Institute. Bill of Rights These amendments function as a concrete list of things Congress and federal agencies simply cannot do, no matter how popular the idea might be.
The Fifth and Fourteenth Amendments
Two Due Process Clauses work in tandem. The Fifth Amendment bars the federal government from depriving any person of “life, liberty, or property, without due process of law.”8Constitution Annotated. Amdt5.5.1 Overview of Due Process The Fourteenth Amendment imposes the same restriction on state governments, adding that no state may “deny to any person within its jurisdiction the equal protection of the laws.”9Legal Information Institute. 14th Amendment
The Fourteenth Amendment also enabled what lawyers call the incorporation doctrine. As originally written, the Bill of Rights restrained only the federal government. Through a long series of court decisions, the Fourteenth Amendment’s Due Process Clause has been used to apply nearly all of those protections to state and local governments as well. Your free speech rights, your protection against unreasonable searches, and most other Bill of Rights guarantees now apply regardless of which level of government is acting.
When Government Can Restrict a Right
No right is absolute in practice. The government can restrict even fundamental freedoms, but courts apply increasingly demanding tests depending on which right is at stake. The harder the test, the less likely the restriction survives.
Strict Scrutiny
When a law burdens a fundamental right or targets a suspect classification like race, courts apply strict scrutiny. To survive this test, the government must show three things: the law serves a compelling interest, it is narrowly tailored to achieve that interest, and it uses the least restrictive means available.10Legal Information Institute. Strict Scrutiny Most laws that reach this level of review fail.
Intermediate Scrutiny
Laws that classify people by gender or affect certain First Amendment interests face intermediate scrutiny. The government must demonstrate an important interest and show that the law is substantially related to achieving it.11Legal Information Institute. Intermediate Scrutiny The bar is real but lower than strict scrutiny.
Rational Basis Review
When no fundamental right or suspect classification is involved, courts apply the most deferential standard: rational basis review. The government only needs to show a legitimate interest and a rational connection between the law and that interest.12Legal Information Institute. Rational Basis Test Routine economic regulations and licensing requirements usually fall into this category, and most survive review easily.
What You Can Do When a Right Is Violated
Identifying a right on paper matters far less than having a way to enforce it. Federal law provides two primary tools for holding government officials accountable when they violate your constitutional rights, plus one significant obstacle that frequently stands in the way.
Suing State and Local Officials
Under 42 U.S.C. ยง 1983, you can sue any person who deprives you of a constitutional right while acting under the authority of state or local law. The statute covers police officers, public school administrators, prison officials, and anyone else exercising government power. If you win, the court can award monetary damages and injunctive relief.13Office of the Law Revision Counsel. 42 U.S. Code 1983 – Civil Action for Deprivation of Rights Section 1983 is the workhorse of constitutional litigation and accounts for a large share of federal civil rights cases.
Suing Federal Officials
Section 1983 does not cover federal agents. For constitutional violations committed by federal officers, the equivalent remedy is a Bivens action, named after the 1971 Supreme Court case Bivens v. Six Unknown Named Agents. The Court held in that case that a person whose Fourth Amendment rights were violated by federal agents could sue for damages even without a statute explicitly authorizing the lawsuit.14Legal Information Institute. Bivens Action In recent years, the Supreme Court has significantly narrowed the availability of Bivens claims, making it harder to extend this remedy to new categories of constitutional violations.
The Qualified Immunity Barrier
Even when a constitutional violation is clear, government officials can avoid personal liability through qualified immunity. This doctrine shields officers from damages unless their conduct violated a right that was “clearly established” at the time. Courts ask whether a reasonable official in the same position would have known the conduct was unconstitutional, based on the law as it existed when the violation occurred.15Legal Information Institute. Qualified Immunity If no prior court decision addressed substantially similar facts, the right may not qualify as “clearly established,” and the official walks away even if the court agrees the conduct was unconstitutional. Many civil rights claims fall apart at this step, and the doctrine remains one of the most contested in American law.
