Roe v. Wade, 410 U.S. 113 (1973)

Author: Blackmun (majority) Outcome: Plaintiffs win ($d = 1$: Texas abortion statute violates DP) Concurrences: Burger, Douglas, Stewart Dissents: White, Rehnquist


1. Holding ($H_t$)

"A state criminal abortion statute of the current Texas type, that excepts from criminality only a life-saving procedure on behalf of the mother, without regard to pregnancy stage and without recognition of the other interests involved, is violative of the Due Process Clause of the Fourteenth Amendment." (p. 164)

"For the stage prior to approximately the end of the first trimester, the abortion decision and its effectuation must be left to the medical judgment of the pregnant woman's attending physician." (p. 164)

"For the stage subsequent to approximately the end of the first trimester, the State, in promoting its interest in the health of the mother, may, if it chooses, regulate the abortion procedure in ways that are reasonably related to maternal health." (p. 164)

"For the stage subsequent to viability, the State, in promoting its interest in the potentiality of human life, may, if it chooses, regulate, and even proscribe, abortion except where it is necessary, in appropriate medical judgment, for the preservation of the life or health of the mother." (p. 164-165)

As constraint on admissible $(w, c)$: The holding establishes a trimester framework that delineates the state's regulatory power over abortion. In the first trimester, the state cannot regulate abortion beyond requiring that it be performed by a licensed physician. In the second trimester, the state may regulate abortion procedures in ways reasonably related to maternal health. After viability, the state may regulate or prohibit abortions, except where necessary to preserve the life or health of the mother. This framework constrains decision rules by requiring that any state regulation of abortion be justified by a compelling state interest and narrowly tailored to serve that interest.

What the holding does NOT constrain:


2. Fact vector $z_t$

2a. Raw salient facts

2b. Dimension mapping

Dimension Value Raw fact(s) mapped Textual basis
D1 Liberty interest type Privacy-intimacy Medical judgment; historical context "right of personal privacy" (p. 153)
D2 Historical grounding Low Historical context "restrictive criminal abortion laws... are of relatively recent vintage" (p. 129)
D3 Level of generality Broad Liberty interest type "right of personal privacy... broad enough to encompass a woman's decision whether or not to terminate her pregnancy" (p. 153)
D4 Government interest strength Compelling (post-first trimester) State interests "State has a legitimate interest in protecting... potentiality of human life" (p. 162)
D5 Intrusion severity High Pregnancy duration; medical safety "denying this choice altogether is apparent" (p. 153)
D6 Methodology Balancing State interests; medical safety "compelling state interest" test (p. 162)
D7 Institutional setting Medical Medical judgment; medical safety "abortion decision... inherently, and primarily, a medical decision" (p. 166)
D8 Precedent density Low Historical context "laws were not of ancient or common-law origin" (p. 129)

Unmapped facts:

Notable: The Court's reliance on a trimester framework is a novel approach, emphasizing the evolving nature of state interests and medical realities over the course of a pregnancy.


3. Treatment of prior holdings ($\mathcal{F}_t$ update)

Griswold v. Connecticut (1965)

Lochner v. New York (1905)


4. Overruling (constraint removal at cost $C$)

What is removed: The Texas statute's blanket prohibition on abortion, except to save the mother's life, is removed.

Justification (mapping to stare decisis factors):

Institutional cost: The decision imposes a new legal framework that requires states to adjust their abortion regulations, but it does not mandate immediate changes, allowing for gradual adaptation.


5. Breadth

Narrow reading (what the Court explicitly holds):

Broad reading (what the reasoning supports):

Breadth ambiguity: The opinion leaves open questions about the precise definition of viability and the specific regulations states may impose in the second trimester. The extent to which the decision applies to non-physician-performed abortions is also unclear.

7. Reasoning revealing implicit weights on dimensions

Privacy as a fundamental right (D1 weight is high):

"This right of privacy... is broad enough to encompass a woman's decision whether or not to terminate her pregnancy." (p. 153)

The Court places significant weight on the privacy dimension, recognizing it as a fundamental right that limits state regulation.

State interests evolve over pregnancy (D4 weight changes):

"At some point in pregnancy, these respective interests become sufficiently compelling to sustain regulation of the factors that govern the abortion decision." (p. 162)

The Court acknowledges that the state's interest in protecting health and potential life becomes compelling at different stages, justifying increased regulation as pregnancy progresses.

Medical safety and modern techniques (D5 weight is high):

"Modern medical techniques have altered this situation... abortion in early pregnancy... is now relatively safe." (p. 149)

The Court emphasizes the reduced intrusion severity due to medical advancements, supporting the decision to limit state regulation in the early stages of pregnancy.

Historical context and evolving standards (D2 weight is low):

"The restrictive criminal abortion laws... are not of ancient or even of common-law origin." (p. 129)

The Court downplays historical grounding, focusing instead on contemporary medical and social understandings to justify its decision.
