The Bill of Rights Series

Amendment IX: The List Was Never the Whole Story

---

Part 9 of a 10-part series examining the Bill of Rights — and the federal record of violating it.

---

The Ninth Amendment exists because the Framers understood that writing down a list of rights creates a problem. Once the list exists, someone will argue that anything not on it was surrendered.

“The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.”

That is the entire amendment. It does not name a single right. It does not describe a specific protection. It does one thing: it tells courts and governments that the list is not exhaustive, that the people retain rights beyond those written down, and that the absence of a specific clause is not permission to regulate.

James Madison included it for a precise reason. Anti-Federalists had warned during ratification that a Bill of Rights would backfire — that listing some freedoms would imply that unlisted freedoms did not exist. Madison’s answer was the Ninth Amendment. It closes that inference before it can be drawn.

What It Does and Does Not Do

The Ninth Amendment is not a blank check for courts to invent new rights from scratch. It is a rule of construction — an instruction about how to read the Constitution. When the government argues that it may regulate some aspect of personal life because no specific clause forbids it, the Ninth Amendment answers that the absence of a clause is not the same as the presence of permission.

The distinction matters. A constitution that grants limited powers to the government and retains everything else for the people reads differently from a constitution that lists specific rights and treats everything else as available for regulation. The Ninth Amendment insists on the first reading. The government’s default position has often been the second.

In practice, courts have rarely decided cases on the Ninth Amendment alone. Unenumerated rights have more often been protected through the Due Process Clauses of the Fifth and Fourteenth Amendments. But the Ninth Amendment reinforces those decisions — it confirms that the Constitution was never understood as a complete catalog of the only liberties the people possess.

Griswold and the Right to Privacy

The most prominent example is Griswold v. Connecticut (1965), which struck down a state law banning the use of contraceptives by married couples. The Constitution contains no clause that says “the right to marital privacy shall not be violated.” Connecticut argued that the absence of such a clause left the matter to the legislature.

The Court disagreed. Justice Goldberg’s concurrence invoked the Ninth Amendment directly — the fact that privacy is not enumerated does not mean it is unprotected. The right existed. The people retained it. The failure to list it was not its surrender.

The decision has been criticized from multiple directions. Some argue that the Court used the Ninth Amendment as cover for judicial policymaking — that “unenumerated rights” is simply a label for whatever the justices happen to prefer. Others argue the opposite: that courts have been too reluctant to enforce the amendment’s plain instruction, deferring to legislatures in areas where the Constitution’s structure requires something more.

Both criticisms are coherent. What they share is an acknowledgment that the Ninth Amendment creates a genuine problem for courts — how to protect rights the Constitution does not name without substituting judicial preference for constitutional principle. The amendment does not solve that problem. It creates the obligation to take it seriously.

The Government’s Default Position

When the Constitution is silent on a particular liberty, government’s default position is that the silence is permission. The Ninth Amendment says otherwise. It says the silence means nothing about whether the right exists — only that the Framers did not write it down.

This plays out most clearly in areas where government claims broad regulatory authority over personal decisions — parental choices about children’s education and upbringing, medical decisions, associational choices that carry no specific textual protection. Courts have recognized some of these as fundamental even without a named clause. They have done so inconsistently, applying different levels of scrutiny at different times to similar categories of claims.

The inconsistency is not random. It reflects a genuine tension between two legitimate concerns: that unenumerated rights need protection, and that judges identifying unenumerated rights are doing something that looks more like legislation than interpretation. The Ninth Amendment does not resolve that tension. It establishes that the tension must be confronted — that dismissing a liberty claim because it lacks a textual address is not a constitutional answer.

The Amendment’s Structural Role

The Ninth Amendment works alongside the Tenth. The Tenth Amendment says that powers not delegated to the federal government are reserved to the states or to the people. The Ninth says that rights not enumerated are retained by the people. Together they describe a constitutional structure in which the federal government has limited, delegated powers and the people retain everything else — both the powers not granted and the rights not listed.

That structure is the opposite of the assumption that what the Constitution does not prohibit, the government may do. The Founders built a system in which the question runs the other direction: not whether the Constitution forbids this, but whether the Constitution authorizes it. The Ninth Amendment is part of that architecture. It sits at the boundary between what was written down and what was retained, holding the line against the inference that the boundary is the whole map.

The Pattern

Every expansion of government power into areas the Constitution does not expressly address involves an implicit claim that the silence is permission. The Ninth Amendment was written to reject that claim before it could be made.

Whether that rejection has held depends on who is doing the reading. Courts that treat the Ninth Amendment as a rule of construction — an instruction to read the Constitution as a charter of limited government and retained rights — produce different outcomes than courts that treat it as a historical curiosity with no practical application.

The amendment does not tell courts which unenumerated rights to protect. It tells them that the question must be asked — that a liberty interest cannot be dismissed simply because no Founder wrote it in the margin. The Bill of Rights was a floor, not a ceiling. The Ninth Amendment is the clause that says so.

Next: The Tenth Amendment — powers reserved to the states and to the people, federalism as a structural protection of liberty, and what happens when the federal government decides the reservation does not apply to it.
