Planned Parenthood of Southeastern Pennsylvania v. Casey, 505 U.S. 833 (1992)

Author: O'Connor, Kennedy, and Souter (plurality) Outcome: Mixed ($d = 0/1$: some provisions upheld, others struck down) Concurrences: Stevens, Blackmun Dissents: Rehnquist, Scalia


1. Holding ($H_t$)

"The essential holding of Roe v. Wade should be retained and once again reaffirmed." (p. 846)

"An undue burden exists, and therefore a provision of law is invalid, if its purpose or effect is to place substantial obstacles in the path of a woman seeking an abortion before the fetus attains viability." (p. 878)

As constraint on admissible $(w, c)$: The holding reaffirms the right to choose an abortion before viability without undue interference from the state. It introduces the "undue burden" standard, which invalidates laws that place substantial obstacles in the path of a woman seeking a pre-viability abortion. This standard replaces the strict scrutiny framework of Roe, allowing for more state regulation provided it does not impose an undue burden.

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 Informed consent requirement; spousal notification "A woman's right to choose to have an abortion before viability" (p. 846)
D2 Historical grounding Low Spousal notification "The Constitution says absolutely nothing about it" (Scalia, p. 980)
D3 Level of generality Narrow Informed consent requirement "The decision to terminate or continue a pregnancy" (p. 928)
D4 Government interest strength Strong Parental consent for minors; informed consent requirement "The State has legitimate interests from the outset of the pregnancy" (p. 846)
D5 Intrusion severity High Spousal notification "A substantial obstacle in the path of a woman seeking an abortion" (p. 878)
D6 Methodology Balancing Undue burden standard "An undue burden exists... if its purpose or effect is to place substantial obstacles" (p. 878)
D7 Institutional setting Medical regulation Recordkeeping and reporting "A report of each abortion performed shall be made to the department" (p. 910)
D8 Precedent density High conflict Reaffirmation of Roe; introduction of undue burden standard "The essential holding of Roe v. Wade should be retained" (p. 846)

Unmapped facts:

Notable: The Court's introduction of the "undue burden" standard marks a significant shift from the strict scrutiny framework, allowing for more nuanced state regulation of abortion.


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

Roe v. Wade (1973)

Akron v. Akron Center for Reproductive Health (1983); Thornburgh v. American College of Obstetricians and Gynecologists (1986)


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

What is removed: The strict scrutiny framework for evaluating abortion regulations is removed, replaced by the undue burden standard.

Justification (mapping to stare decisis factors):

Institutional cost: The Court emphasizes the importance of maintaining its legitimacy and the stability of constitutional law, suggesting that overruling Roe entirely would undermine these values.


5. Breadth

Narrow reading (what the Court explicitly holds):

Broad reading (what the reasoning supports):

Breadth ambiguity: The precise application of the undue burden standard is left open, creating potential for varied interpretations in future cases.


6. Concurrences / dissents (alternative admissible theories)

Stevens (concurring in part, dissenting in part)

Blackmun (concurring in part, dissenting in part)

Rehnquist, Scalia, White, Thomas (dissenting)


7. Reasoning revealing implicit weights on dimensions

Liberty interest type (D1 weight is high):

"The Constitution protects a woman's right to terminate her pregnancy in its early stages." (p. 844)

The Court emphasizes the importance of the woman's liberty interest, suggesting a high weight on D1.

Government interest strength (D4 weight is strong):

"The State has legitimate interests from the outset of the pregnancy in protecting the health of the woman and the life of the fetus that may become a child." (p. 846)

The Court acknowledges strong state interests, indicating a high weight on D4.

Intrusion severity (D5 weight is high):

"An undue burden exists... if its purpose or effect is to place substantial obstacles in the path of a woman seeking an abortion before the fetus attains viability." (p. 878)

The Court's focus on substantial obstacles suggests a high weight on D5, prioritizing the woman's access to abortion services.
