Lesson 17: Privacy Rights & the Legacy of Roe

Starter (~150 words)

Search the Constitution for the word "privacy." You won't find it. It isn't in the original text, it isn't in the Bill of Rights, and it isn't in any of the 27 amendments. And yet for nearly half a century, "the right to privacy" was one of the most consequential phrases in American constitutional law — the foundation of decisions touching contraception, marriage, family, and abortion.

How does a right that is nowhere written down become law? And once a court has recognized such a right, can a later court take it away?

Those two questions sit at the center of today's lesson. We are going to follow a single constitutional idea across nearly sixty years — through four Supreme Court cases that built it, modified it, and ultimately overturned a major part of it. Our goal isn't to settle the political fight. It's to understand the legal machinery: how interpretation works, and how precedent can change.

Core Concepts (~1000–1200 words)

A right that isn't in the text

The Constitution protects many rights explicitly — speech, religion, the right to counsel. These are enumerated rights: written down, named, listed. But the framers also anticipated that they could not possibly list every liberty. The Ninth Amendment says so directly: "The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people." In other words, the fact that a right isn't named doesn't mean it doesn't exist. Rights that are protected without being explicitly listed are called unenumerated rights, and the right to privacy is the most famous example.

The question that divides constitutional thinkers is how judges should identify these unwritten rights — and whether they should at all.

Griswold and the "penumbras"

The right to privacy was first articulated by the Supreme Court in Griswold v. Connecticut (1965). Connecticut had a law banning the use of contraceptives, even by married couples, and the executive director of Planned Parenthood was convicted for counseling married couples about birth control. The Court struck the law down.

Writing for the majority, Justice William O. Douglas reasoned that several specific guarantees in the Bill of Rights create "penumbras" — shadows or zones of protection that extend beyond the literal words. The First Amendment's freedom of association, the Third's bar on quartering soldiers in homes, the Fourth's protection against unreasonable searches, the Fifth's protection against self-incrimination, and the Ninth's reservation of unlisted rights all point, Douglas argued, toward a broader right to privacy — especially within the marital relationship. No single clause says "privacy," but together they imply a protected private sphere the government may not invade. With Griswold, the right to privacy entered American constitutional law.

Substantive due process

Later cases anchored the privacy right more firmly in the Fourteenth Amendment, through a doctrine called substantive due process. The 14th Amendment's Due Process Clause says no state shall "deprive any person of life, liberty, or property, without due process of law." Read narrowly, "due process" is about procedures — fair notice, a fair hearing. But under substantive due process, the word "liberty" is read to protect certain fundamental rights from government interference no matter what procedures are used. The theory: some liberties are so basic that the government cannot take them away at all. Substantive due process is also the vehicle through which most of the Bill of Rights has been incorporated against the states (covered in Lesson 14). It is powerful — and controversial — precisely because it asks unelected judges to decide which unwritten liberties count as "fundamental."

Roe v. Wade (1973)

In Roe v. Wade (1973), the Court held that the constitutional right to privacy was "broad enough to encompass a woman's decision whether or not to terminate her pregnancy." Grounding the right primarily in the 14th Amendment's concept of personal liberty, Justice Harry Blackmun's majority opinion (7–2) treated the abortion decision as part of the protected zone of privacy — but not an unlimited one. The state had legitimate interests too: protecting the health of the pregnant woman and protecting "the potentiality of human life."

To balance the privacy right against those state interests, Roe created the trimester framework: - In the first trimester, the decision was left to the woman and her physician, with little room for state regulation. - In the second trimester, the state could regulate abortion in ways reasonably related to maternal health. - In the third trimester — after fetal viability — the state could regulate and even prohibit abortion, except where necessary to preserve the woman's life or health.

The key takeaway for the exam: Roe recognized a constitutional right to abortion as an application of the privacy right, and used the trimester framework to manage the balance.

Planned Parenthood v. Casey (1992)

Nearly two decades later, Planned Parenthood v. Casey (1992) revisited Roe. A divided Court reaffirmed what it called the "essential holding" of Roe — that there is a constitutional right to choose an abortion before viability — but it discarded the trimester framework. In its place the Court adopted the "undue burden" standard: a state regulation is unconstitutional if it places "a substantial obstacle in the path of a woman seeking an abortion" before viability. Applying that test, Casey upheld several Pennsylvania requirements (such as a 24-hour waiting period and informed-consent provisions) while striking down a spousal-notification requirement. Casey is the bridge case: the right survived, but the legal test changed, and the Court leaned heavily on stare decisis — respect for precedent — as a reason to retain Roe's core.

Dobbs v. Jackson Women's Health Organization (2022)

Then came Dobbs v. Jackson Women's Health Organization (2022). Reviewing a Mississippi law banning most abortions after 15 weeks, the Court did something far larger than rule on that statute. Writing for the majority, Justice Samuel Alito held that the Constitution does not confer a right to abortion, and that Roe and Casey were both overruled. The majority reasoned that a right to abortion is not mentioned in the Constitution and is not "deeply rooted in this Nation's history and tradition" — the test it drew from earlier substantive-due-process cases. Because no such right exists in the Constitution, the Court held, "the authority to regulate abortion is returned to the people and their elected representatives" — that is, to the states.

The single most important fact in this lesson: the right to privacy that included the abortion decision was recognized in Roe v. Wade (1973) and overturned by Dobbs v. Jackson (2022). Abortion is now regulated state by state.

The state-by-state landscape

Because Dobbs removed the federal constitutional floor, abortion policy now varies enormously by state. Some states protect access by statute or in their state constitutions; others restrict or prohibit it; many fall somewhere in between with gestational limits. The result is a patchwork: the legality of the same act can differ depending on which state line you are standing behind. This is federalism in action — when there is no national constitutional rule on a question, the matter returns to the states, and fifty different policy choices become possible.

In Practice. Dobbs did not ban abortion nationwide, and it did not make it legal nationwide. That is the most common misreading. What Dobbs did was remove the question from federal constitutional law and hand it to the political process — Congress and, above all, the state legislatures and state courts. After Dobbs, the most consequential abortion battles moved to state ballot measures, state legislatures, and state supreme courts. A right that was once decided in Washington is now contested in fifty capitals.

The larger debate

Dobbs reignited a deeper argument about substantive due process itself: how should courts decide which unwritten liberties are "fundamental"? The majority emphasized history and tradition. The dissent warned that the same reasoning could unsettle other privacy-based rights. The Court's majority opinion stated that its holding concerned abortion alone. Whatever one's view, the Roe-to-Dobbs arc is the clearest modern case study of a single point: constitutional interpretation can shift, and precedent — even decades old — can be overturned.

Document Spotlight (~300 words): Unenumerated Rights — the Ninth & Fourteenth Amendments

Context. The whole privacy line of cases rests on a structural feature of the Constitution: it protects more than it explicitly lists. Two textual hooks make this possible. The Ninth Amendment (ratified 1791) was added to answer a fear voiced during ratification — that listing some rights might imply the government could trample any right left off the list. The Fourteenth Amendment (ratified 1868) then turned the federal government's guarantee of "liberty" against the states.

Key quotes.

"The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people." — Ninth Amendment

"...nor shall any State deprive any person of life, liberty, or property, without due process of law..." — Fourteenth Amendment, Section 1

What it means. The Ninth Amendment says the rights named in the Constitution are not the only rights the people have — there are unenumerated rights "retained by the people." But the Ninth Amendment doesn't say which ones, and it isn't self-enforcing. The heavy lifting is done by the Fourteenth Amendment's "liberty," which courts have read through substantive due process to protect certain fundamental, unlisted liberties from state interference. Griswold invoked the penumbras and the Ninth; Roe leaned on the Fourteenth.

How it's used on the AP exam. When a prompt involves a right not spelled out in the text — privacy, marriage, family decisions — these are your anchors. The exam loves the tension here: the Ninth says unlisted rights exist; critics counter that it gives judges no standard for identifying them, inviting judicial overreach. In an FRQ, use the Ninth and Fourteenth Amendments to explain how an unenumerated right can be recognized — then acknowledge the counterargument that doing so hands unelected judges great discretion. That tension is exactly what Dobbs turned on.

SCOTUS Case Breakdown

Roe v. Wade (1973)

Facts of the case. A pregnant woman in Texas, using the legal pseudonym "Jane Roe," challenged a Texas law that criminalized abortion except to save the life of the mother. She argued the law violated her constitutional right to privacy. The case reached the Supreme Court as a challenge to the Texas statute on behalf of women seeking abortions.

Constitutional question. Does the Constitution's right to privacy, grounded in the Fourteenth Amendment's Due Process Clause, extend to a woman's decision to have an abortion?

Holding. Yes. The Court held (7–2) that the right to privacy is "broad enough to encompass a woman's decision whether or not to terminate her pregnancy," though that right is not absolute and must be balanced against the state's interests.

Reasoning. Justice Blackmun located the privacy right in the "concept of personal liberty" protected by the Fourteenth Amendment's Due Process Clause (building on Griswold). But the Court recognized two legitimate, growing state interests: protecting maternal health and protecting potential life. To reconcile the right with those interests, the Court adopted the trimester framework, giving the woman near-total decision-making in the first trimester, allowing health regulations in the second, and permitting prohibition after viability (subject to a life/health exception) in the third.

Impact. Roe established a nationwide constitutional standard for abortion and became one of the most debated decisions in the Court's history. It was modified by Planned Parenthood v. Casey (1992), which kept the core right but replaced the trimester framework with the undue burden standard — and then overturned by Dobbs v. Jackson (2022).

Dobbs v. Jackson Women's Health Organization (2022)

Facts of the case. Mississippi's "Gestational Age Act" prohibited most abortions after 15 weeks of pregnancy — earlier than viability. Jackson Women's Health Organization, the state's only licensed abortion clinic, challenged the law as unconstitutional under Roe and Casey. The state asked the Court to uphold the law and reconsider those precedents.

Constitutional question. Does the Constitution confer a right to obtain an abortion?

Holding. No. The Court held (with six justices upholding the Mississippi law, and five voting to overrule the prior cases entirely) that the Constitution does not confer a right to abortion, and it overruled both Roe and Casey.

Reasoning. Justice Alito's majority opinion reasoned that the right to abortion is not enumerated in the Constitution and, to be protected as an unenumerated right under substantive due process, it would need to be "deeply rooted in this Nation's history and tradition" — a test the majority concluded abortion failed. Without a constitutional basis, the Court held, the issue does not belong to the federal judiciary. Therefore "the authority to regulate abortion is returned to the people and their elected representatives" — the states. The dissent argued the decision broke with stare decisis and undermined the privacy line of cases; the majority responded that its holding was limited to abortion.

Impact. Dobbs ended the federal constitutional right to abortion recognized in Roe and returned regulatory authority to the states, producing a state-by-state legal landscape. It stands as the leading modern example of the Supreme Court overturning its own precedent and reallocating a contested issue from federal constitutional law to the democratic/state level.

Also note: Griswold v. Connecticut (1965) first articulated the privacy right via the "penumbras" of the Bill of Rights, striking down a ban on contraceptives for married couples. Planned Parenthood v. Casey (1992) retained a constitutional right to abortion but swapped Roe's trimester framework for the undue burden standard.

Application Practice (~400 words)

Use the four-step move: Identify the issue → State the principle → Apply it → Predict the outcome.

Scenario 1 — An unenumerated-rights claim. A state passes a law restricting a private family decision. A resident sues, arguing the law violates a "right to privacy," even though the Constitution never uses that word. The state responds that no such right is written in the text.

• Issue: Whether an unenumerated right can be enforced against a state.
• Principle: The Ninth Amendment says unlisted rights are "retained by the people," and substantive due process under the Fourteenth Amendment has been used to protect certain fundamental unwritten liberties (as in Griswold).
• Apply: The resident must argue the liberty is fundamental; the state will argue that recognizing unwritten rights gives judges too much discretion and that the right must be "deeply rooted in history and tradition" (the Dobbs test).
• Predict: The outcome turns on whether a court finds the claimed liberty fundamental under existing precedent — which is exactly why these cases are contested.

Scenario 2 — How Dobbs changed the federal-vs-state allocation. Two neighboring states adopt opposite abortion policies after 2022. A commentator says one of them must be violating the Constitution.

• Issue: Whether differing state abortion laws are constitutionally permissible after Dobbs.
• Principle: Dobbs held the Constitution confers no right to abortion and returned the issue to the states.
• Apply: With no federal constitutional rule in place, federalism allows each state to set its own policy through its legislature, courts, or ballot measures.
• Predict: Both states can have valid but opposite laws. Neither is "violating the Constitution" simply by differing — that is the predictable result of returning a question to the states.

Scenario 3 — Stare decisis. A litigant asks the Supreme Court to overturn a 30-year-old precedent. Opponents argue the Court must follow precedent.

• Issue: The weight of stare decisis when a precedent is challenged.
• Principle: Stare decisis is a strong presumption in favor of following precedent — not an absolute bar. The Court can overturn precedent (as Dobbs overruled Roe and Casey; as Brown overruled Plessy).
• Apply: The Court weighs factors like whether the prior rule was "egregiously wrong," workable, and relied upon. Reasonable justices disagree on how much weight precedent deserves.
• Predict: Don't assume precedent is permanent — but don't assume it's disposable either. The strength of stare decisis is itself the question.

Traps & Confusions (~250 words)

Get the direction right: Roe vs. Dobbs. This is the highest-value fact in the lesson. Roe v. Wade (1973) RECOGNIZED the constitutional right (as part of privacy). Dobbs v. Jackson (2022) OVERTURNED it and returned the issue to the states. Reversing these — saying Roe banned abortion, or that Dobbs created a right — is a fatal error. Roe = recognized; Dobbs = overturned; now = state by state.

Dobbs did not ban (or legalize) abortion nationwide. It removed the federal constitutional rule and sent the question to the states. The result is a patchwork, not a national ban and not a national right.

Privacy is unenumerated. The word "privacy" is not in the Constitution. The right was inferred — from the "penumbras" of the Bill of Rights (Griswold) and from substantive due process under the 14th Amendment. If a question implies privacy is explicitly written in the text, it's wrong.

Substantive vs. procedural due process. Procedural due process = fair procedures (notice, a hearing). Substantive due process = certain liberties themselves are protected from government interference, regardless of procedure. The privacy cases are substantive.

Federal constitutional right vs. state regulation. Before Dobbs, abortion was a federal constitutional right (a national floor). After Dobbs, it is a matter of state regulation. Mixing up "the Constitution requires X" with "a state has chosen X" is a classic federalism slip.

Practice Problems (12–15)

FRQ Practice — Argument Essay (FRQ 4)

This is FRQ 4, the Argument Essay, scored on the College Board's 6-point rubric. The structure is the same every time:

The non-negotiable rule: an AP Gov argument essay must use the required foundational documents named in the prompt, and the strongest responses fully explain two. For this prompt the natural pair is Federalist No. 78 (judicial duty, precedent, and preferring the Constitution) and Brutus No. 1 (the danger of an unaccountable, centralized power).

THE PROMPT

Some argue that the Supreme Court should give strong weight to stare decisis — its own precedents — and only rarely overturn them, in order to keep the law stable and predictable. Others argue that the Court's primary duty is to the Constitution itself, so that it should overturn a precedent it concludes was wrongly decided, even a long-standing one.

Develop an argument about whether the Supreme Court should give greater weight to precedent (stare decisis) or to its own independent interpretation of the Constitution when the two conflict.

In your essay, you must: - Articulate a defensible claim or thesis that responds to the prompt and establishes a line of reasoning. - Support your claim with at least TWO pieces of accurate and relevant evidence. - At least TWO pieces of evidence must come from the required foundational documents. At least one must be from: Federalist No. 78, Brutus No. 1, or Federalist No. 51. - Use reasoning to explain why your evidence supports your claim. - Respond to an opposing or alternative perspective using refutation, concession, or rebuttal.

(Either side is fully defensible — the rubric rewards the argument, not the conclusion. The model below argues one side; an equally strong essay could argue the other.)

MODEL RESPONSE

(Claim — Element A): The Supreme Court should generally give strong weight to stare decisis and overturn precedent only in rare, clearly justified cases, because stable precedent protects the rule of law and constrains the discretion of unelected judges — even though the Court's ultimate duty to the Constitution means precedent can never be absolutely binding.

(Evidence Document #1 + Reasoning — Federalist No. 78): Federalist No. 78 supports giving precedent strong weight. Hamilton argued that "to avoid an arbitrary discretion in the courts, it is indispensable that they should be bound down by strict rules and precedents." Because federal judges are unelected and serve for life, Hamilton worried that without the discipline of precedent, judging would collapse into personal preference. This supports my claim because stare decisis is precisely that discipline: by requiring judges to follow established rules, it limits the danger that a new majority will simply rewrite the law to match its own views. At the same time, Fed 78 acknowledges the other side — Hamilton also wrote that where a law conflicts with the Constitution, "the Constitution ought to be preferred," which is why precedent must yield in the rare case where it is clearly unconstitutional.

(Evidence Document #2 + Reasoning — Brutus No. 1): Brutus No. 1, the Anti-Federalist essay, warned that a powerful, centralized federal government — and especially its courts — could become unaccountable to the people — Brutus warned that "the powers of the general legislature extend to every case that is of the least importance." This supports my claim because a Court that freely overturns its own precedents exercises exactly the kind of unchecked, far-reaching power Brutus feared from an unelected national institution. Strong respect for stare decisis answers that fear: it ties the Court to rules it announced before, making its power more predictable and less personal, and reassuring the public that constitutional rights do not vanish whenever the Court's membership changes.

(Additional evidence — course knowledge): Beyond the documents, the doctrine of judicial review established in Marbury v. Madison (1803) gives the Court enormous power to say "what the law is." That power is more legitimate when it is constrained by precedent. The contrast between Planned Parenthood v. Casey (1992), which leaned on stare decisis to retain a prior holding, and Dobbs v. Jackson (2022), which overturned it, shows how consequential the choice is: when the Court overrules a long-standing precedent, a nationwide constitutional rule can change. That magnitude is exactly why overturning precedent should be rare.

(Responding to an alternative perspective — Element D): A strong counterargument holds that the Court's duty is to the Constitution, not to its own past mistakes, so it should overturn precedents it concludes were wrongly decided — otherwise an early error becomes permanent. This view has real force; Brown v. Board of Education (1954) overruled Plessy v. Ferguson, and few would defend keeping a precedent merely because it is old. I concede that stare decisis cannot be absolute. But this objection actually defines the boundary of my claim rather than defeating it: precedent should yield only when a ruling is demonstrably and seriously wrong, not whenever a new majority disagrees. As Fed 78 implies, the choice is between disciplined judging and "arbitrary discretion" — and a presumption favoring precedent, overcome only by a strong showing, best preserves both constitutional fidelity and the rule of law.

POINT-BY-POINT SCORING OF THE MODEL

Score: 6/6.

COMMON POINT LOSS

• Restated thesis (–1). "Precedent is important" with no because and no side chosen earns nothing. Pick stare decisis or independent interpretation and give a reason.
• Only one required document (–evidence points). This prompt requires two. Citing Fed 78 alone, even well, caps your evidence score. Plan your pair (Fed 78 + Brutus 1) before writing.
• Naming a document without explaining it (–1). "Brutus 1 is anti-federalist" is a label. Connect it to your claim about precedent and judicial power.
• No counterargument (–1). The opposite view ("duty to the Constitution, overrule errors") is the obvious alternative — name it and answer it. Don't skip Element D.
• Taking a side on abortion instead of on the legal question (–credibility). This prompt is about stare decisis vs. constitutional interpretation, not about abortion policy. Use Roe/Casey/Dobbs only as a neutral example of how precedent can change. An essay that argues the policy merits of abortion is off-task.
