Griswold v. Connecticut and the Birth of the Right to Privacy

What was the Connecticut law in Griswold?

The Connecticut law in Griswold made it a crime for anyone to use a drug, medicinal article or instrument to prevent conception. Section 53-32 of the General Statutes punished such use with a fine of at least $50, imprisonment, or both, and section 54-196 allowed anyone who assisted, abetted or counseled the offense to be prosecuted as if he were the principal offender ^[1]. On its face, the ban made no distinction by marital status, and it reached the use of contraceptives, not just their sale.

The statute was old. The Supreme Court noted in 1961 that it had been on the books since 1879, enacted as chapter 78 of the Connecticut Acts of that year ^[2]. It was rarely enforced: the only known prosecution was State v. Nelson in 1940, a test case against two doctors and a nurse that the state later moved to dismiss ^[2]. Justice William O. Douglas observed in 1961 that this prosecution had nonetheless closed the state's birth-control clinics ^[2]. The plurality in Poe added a telling detail: contraceptives were openly sold in Connecticut drugstores without anyone being prosecuted, which showed how far the use ban had drifted from practice ^[2].

The law sat alongside other morals offenses in Connecticut's criminal code. The state also punished adultery and fornication, a fact that several justices would invoke in 1965 to explain what the state could legitimately regulate and what it could not ^[1].

How did the case reach the Supreme Court?

The case reached the Supreme Court after a first challenge failed on procedural grounds. In Poe v. Ullman, decided on June 19, 1961, the Court dismissed a challenge to the statute because it saw no real or immediate threat of prosecution, describing Connecticut's long non-enforcement as a kind of tacit agreement ^[2]. Justice Felix Frankfurter announced the judgment for four justices, Justice William Brennan concurred in the judgment, and Justices Hugo Black, Douglas and John Marshall Harlan were among the dissenters ^[2].

Harlan's dissent would shape the 1965 decision. He argued that the ban, applied to married couples, was an intolerable invasion of privacy, while accepting that states may enact "laws forbidding adultery, fornication and homosexual practices" as part of a policy of confining sexuality to lawful marriage ^[2]. That distinction between marital intimacy and other sexual conduct would reappear in Griswold. Douglas, dissenting separately, argued that a society which tells doctors, under threat of criminal penalty, what they may not tell their patients is not a free society, and that by making use a crime the state had entered the innermost part of the home ^[2].

The test case followed within months. The Planned Parenthood League of Connecticut opened a center in New Haven that operated from November 1 to November 10, 1961, when its executive director, Estelle Griswold, and its medical director, Dr. Buxton, a licensed physician and professor at Yale Medical School, were arrested ^[1]. They had advised married persons on preventing conception and examined wives to prescribe contraceptives ^[1]. Convicted as accessories and fined $100 each, they saw their convictions upheld by the Connecticut courts before the Supreme Court heard the case in March 1965 ^[1].

What is the penumbra theory of privacy?

The penumbra theory is Justice Douglas's view that the specific guarantees of the Bill of Rights have penumbras, formed by emanations from those guarantees, that together create zones of privacy ^[1]. Writing for the Court on June 7, 1965, Douglas pointed to the First Amendment's protection of association, the Third Amendment's ban on quartering soldiers in homes, the Fourth and Fifth Amendments' protections against searches and self-incrimination, and the Ninth Amendment's reminder that enumerated rights do not exhaust those retained by the people ^[1].

Applied to the case, the theory placed the marriage relationship inside one of those zones. Douglas emphasized that the law targeted the use of contraceptives, and he asked whether police should be allowed to search marital bedrooms for evidence of that use ^[1]. He described marriage as intimate to the point of being sacred ^[1].

Not every justice in the majority accepted this reasoning. Justice Harlan concurred only in the judgment, rejecting the penumbra approach and relying instead on the Due Process Clause of the Fourteenth Amendment, as in his Poe dissent ^[1]. Justice Byron White also concurred in the judgment on due-process grounds ^[1]. Justices Black and Potter Stewart dissented, each joining the other's opinion; Black called privacy a broad, abstract and ambiguous concept that the government may invade unless a specific constitutional provision forbids it ^[1]. Stewart made clear that he considered the statute unwise even as he voted to uphold it ^[1].

Why did a concurrence mention fornication statutes?

A concurrence mentioned fornication statutes to show that the state had other, narrower ways to protect marital fidelity. Justice Arthur Goldberg, joined by Chief Justice Earl Warren and Justice Brennan, wrote that Connecticut had statutes, "the constitutionality of which is beyond doubt," that prohibited adultery and fornication ^[1]. He drew on Harlan's Poe dissent for the idea that the state may forbid certain sexual intimacies outside marriage ^[1][2].

His point was about tailoring. Goldberg argued that the state's interest in discouraging extramarital relations could be served by a more discriminately tailored statute that did not sweep so broadly, and he grounded the right of marital privacy in the Ninth Amendment's recognition that fundamental rights exist beyond those listed in the first eight amendments ^[1]. In his view, the existence of adultery and fornication laws undercut the claim that a ban on married couples' contraceptive use was necessary.

Justice White made a related argument. He accepted that deterring promiscuous or illicit sexual relationships was a legitimate goal for the state, but he found that banning contraceptive use by married couples did nothing meaningful to reinforce Connecticut's criminal prohibitions on illicit sexual conduct ^[1]. The law therefore deprived married persons of liberty without due process.

These passages matter for the history of fornication law because they show that in 1965, three justices who also joined the Court's opinion treated fornication statutes as plainly valid. Griswold protected marriage; it did not question laws aimed at sex outside marriage.

How did Griswold lead to Eisenstadt and Lawrence?

Griswold led to Eisenstadt and Lawrence by establishing a protected sphere of intimate decisions that later cases detached from marriage. On March 22, 1972, Eisenstadt v. Baird struck down a Massachusetts law that limited contraceptives to married people, holding that unequal treatment of married and unmarried people violated the Equal Protection Clause ^[3]. The Court declared that privacy belongs to "the individual, married or single," while expressly leaving open whether the unmarried had a fundamental right of access ^[3]. The full story is told in Eisenstadt v. Baird and unmarried couples.

When the Court decided Lawrence v. Texas on June 26, 2003, it called Griswold the "most pertinent beginning point" for its analysis ^[4]. The majority noted that Griswold had emphasized the marriage relation and the protected space of the marital bedroom, but said that Eisenstadt and later cases showed this reasoning could not be confined to married adults ^[4]. Lawrence struck down a Texas sodomy law and overruled Bowers v. Hardwick, protecting private, consensual conduct between adults ^[4].

The change reversed the assumption Goldberg had stated in 1965. Cornell's Legal Information Institute now explains that, because Lawrence protects private sexual acts under the Due Process Clause, fornication laws cannot be enforced ^[7]. The statutes Goldberg described as beyond constitutional doubt are, in their application to consenting adults in private, now treated as unenforceable. For that later step, see how Lawrence v. Texas undermined fornication laws.

Is Griswold still good law?

Yes: as of October 2026, Griswold has not been overruled, and the Supreme Court's most recent major statement on it was reassuring but contested. On June 24, 2022, in Dobbs v. Jackson Women's Health Organization, the Court overruled its abortion precedents while stating that nothing in its opinion should be understood to cast doubt on precedents that do not concern abortion ^[5]. The majority distinguished cases such as Griswold because, unlike abortion, they do not involve what it called the destruction of a "potential life" ^[5].

Justice Clarence Thomas wrote separately to urge a broader review. He said the Court "should reconsider all of this Court's substantive due process precedents," naming Griswold, Lawrence and Obergefell, and no other justice joined his concurrence ^[6]. His view has not been adopted by the Court.

Griswold's practical scope has also widened since 1965. The decision itself concerned married couples, but the combination of Griswold and Eisenstadt means that, as a matter of constitutional law, a state may not make access to contraception depend on marital status ^[1][3].

The stakes extend to the fornication statutes that remain in some state codes. Their unenforceability against consenting adults rests on Lawrence, which in turn presented itself as the heir of Griswold and Eisenstadt ^[4][7]. Because such laws are rarely enforced, Cornell's Legal Information Institute notes, they are also hard to challenge in court and tend to stay on the books until legislatures repeal them ^[7]. Any future narrowing of the Griswold line would therefore reopen questions that most legislatures and courts now treat as settled. This article summarizes court decisions and is not legal advice.

Frequently asked questions

Who wrote the Griswold opinion?

Justice William O. Douglas wrote the opinion of the Court. Justice Goldberg, joined by Chief Justice Warren and Justice Brennan, added an influential concurrence based on the Ninth Amendment, while Justices Harlan and White concurred only in the judgment.

What was the vote in Griswold v. Connecticut?

The vote was 7-2. Justices Hugo Black and Potter Stewart dissented, each joining the other's opinion. The case was decided on June 7, 1965.

Did Griswold apply to unmarried couples?

No. Griswold protected the use of contraceptives by married couples as part of a right of marital privacy. Unmarried people gained equal access in Eisenstadt v. Baird (1972), which held that treating them differently violated the Equal Protection Clause.

What does "penumbras" mean in Griswold?

It refers to the zones of privacy that Justice Douglas found around specific guarantees of the Bill of Rights. He reasoned that the First, Third, Fourth, Fifth and Ninth Amendments cast penumbras, formed by emanations from those guarantees, and that marriage falls within them.

Why did Justices Black and Stewart dissent?

They found no specific constitutional provision that the law violated. Justice Black called privacy a broad, abstract and ambiguous concept, and Justice Stewart, while openly considering the law unwise, refused to strike it down on that basis.

Did Griswold say fornication laws were constitutional?

Not as a holding, but a concurrence said so. Justice Goldberg, joined by two other justices, described Connecticut's laws against adultery and fornication as beyond constitutional doubt. That assumption was later undercut by Eisenstadt (1972) and Lawrence v. Texas (2003).
