In legal usage, sodomy is an umbrella term for sexual acts that fall outside penile-vaginal intercourse: oral-genital contact, anal intercourse, and sexual contact between a human and an animal. The sodomy legal definition applied regardless of the participants’ sex or marital status, which is why a married couple could technically violate the same statute aimed at anyone else. After the Supreme Court’s 2003 decision in Lawrence v. Texas, these laws cannot be enforced against consenting adults in private, but the statutory term still carries weight in cases involving force, minors, bestiality, immigration consequences, and convictions entered before 2003.
The Three Categories the Term Covers
Courts and legislatures grouped three kinds of conduct under the sodomy label: anal intercourse between any two people, oral-genital contact, and sexual acts between a human and an animal. The breadth was deliberate. Legislators drafted these statutes as catch-all provisions rooted in religious and moral frameworks inherited from English common law, where “buggery” had been a capital offense. A broad definition let prosecutors charge a wide range of private conduct under one heading, and courts reinforced that approach by reading the term expansively when defendants challenged it.
Bestiality sat awkwardly inside this category for most of American legal history, prosecuted under the same “sodomy” or “crime against nature” statutes that covered consensual acts between adults. That grouping reflected the moralistic origins of the laws rather than any coherent theory of harm. Beginning in the late twentieth century, states started pulling bestiality into its own statutory category, often reframing it as animal cruelty or sexual assault of an animal. Oregon, California, and Hawaii are among the states that have adopted language treating these offenses as animal welfare violations.
How Criminal Codes Phrased the Prohibition
Sodomy statutes are notorious for not plainly saying what they prohibit. Legislators relied on euphemisms like “the abominable and detestable crime against nature” or “unnatural acts” to avoid graphic descriptions in the code. That vagueness handed prosecutors and judges wide discretion over what qualified, and it created due process problems because defendants sometimes argued they couldn’t tell in advance whether their behavior fell within such open-ended language.
The American Law Institute attempted a fix in the original 1962 Model Penal Code. Section 213.0 defined “deviate sexual intercourse” as sexual intercourse per os or per anum between human beings who are not husband and wife, and any form of sexual intercourse with an animal. Section 213.2 then used that defined term to describe offenses involving force or imposition, separating coerced acts from merely prohibited ones. The phrase “deviate sexual intercourse” became common statutory shorthand in states that updated their codes, but it coexisted with the older “crime against nature” language rather than replacing it. Many legislatures were reluctant to revisit these provisions at all, since any floor debate about sexual conduct carried political risk.
What Is Still Prosecutable
Lawrence v. Texas held, 6-3, that criminalizing private, consensual sexual conduct between adults violates the Due Process Clause of the Fourteenth Amendment.1Justia. Lawrence v. Texas, 539 U.S. 558 (2003) Justice Kennedy wrote that “Liberty presumes an autonomy of self that includes freedom of thought, belief, expression, and certain intimate conduct,” and that the Texas statute “furthers no legitimate state interest which can justify its intrusion into the individual’s personal and private life.”2Library of Congress. Lawrence et al. v. Texas, 539 U.S. 558 (2003)
The ruling has clear boundaries. Kennedy limited the protected right to conduct in “the home or in other similarly private places” and explicitly excluded public sexual conduct, writing that “the idea of a ‘privacy’ right and a place of public accommodation are, in this context, mutually exclusive.” Sex in a park, a public restroom, or a commercial establishment remains prosecutable even if both parties consent.
Lawrence also did not address sexual contact involving minors, non-consensual encounters, or situations where one party is legally incapable of consent due to incapacitation. Modern sexual assault statutes in every state cover those situations, and many states kept their sodomy-specific language to prosecute forced oral or anal sex as a distinct offense. Where consent is absent or legally impossible, the statutory meaning of sodomy remains fully operative.
Laws Still on the Books After Lawrence
Roughly a dozen states still have sodomy laws in their criminal codes that have never been formally repealed. These statutes are constitutionally unenforceable against consenting adults, but their continued existence creates real problems. Some local law enforcement agencies have used them as a basis for arrests well after 2003, even though convictions cannot stand. The arrests themselves carry consequences: booking records, mugshots, and the disruption of being taken into custody don’t disappear because a charge is eventually dropped.
Repeal has stalled for political reasons. A vote to remove a sodomy statute can be framed by opponents as being soft on crime or endorsing the underlying conduct, which makes repeal bills toxic in some districts. The result is a split between the law on paper and the law in practice. A person reading their state’s criminal code might reasonably believe consensual oral sex is still a felony, even though no court would sustain such a charge.
How Military Law Treats These Offenses
The Uniform Code of Military Justice originally addressed sodomy under Article 125, which criminalized both forcible and consensual sodomy among service members. In 2016, Congress overhauled the UCMJ’s sexual offense provisions. Article 125 was amended to cover kidnapping, and the conduct previously prosecuted as forcible sodomy was folded into the broader sexual assault framework under Articles 120 and 120b.3Office of the Law Revision Counsel. 10 USC 925 – Art. 125. Kidnapping Consensual sodomy between adults is no longer a standalone military offense. Forced oral or anal sex is now prosecuted as sexual assault, with penalties that include lengthy confinement and dishonorable discharge.
Legacy Convictions and Their Consequences
People convicted under sodomy statutes before Lawrence face collateral consequences the Supreme Court’s ruling did not automatically resolve. A conviction that the Constitution now forbids is still a conviction on your record unless a court specifically vacates or expunges it. That distinction matters for employment, housing, and professional licensing.
Sex Offender Registration
The Lawrence opinion itself flagged the registry problem. The Court observed that a person convicted of consensual sodomy in Texas would trigger sex offender registration requirements in at least four states if they relocated there.1Justia. Lawrence v. Texas, 539 U.S. 558 (2003) Removal procedures vary. Some states let individuals convicted of now-decriminalized conduct petition for removal from sex offender databases; others have no clear mechanism.
Immigration Consequences
For non-citizens, a legacy sodomy conviction can be devastating. Federal immigration law makes people deportable or inadmissible based on convictions for “crimes involving moral turpitude.” The State Department’s Foreign Affairs Manual doesn’t list sodomy by name, but it categorizes “gross indecency” and “lewdness” as offenses normally considered crimes involving moral turpitude.4U.S. Department of State Foreign Affairs Manual. 9 FAM 302.3 (U) Ineligibility Based on Criminal Activity, Criminal Convictions and Related Activities – INA 212(a)(2) Whether a particular sodomy conviction qualifies depends on the specific statutory language under which the person was convicted, not the underlying conduct. Immigration judges apply a “categorical approach” that examines the minimum behavior required to violate the statute rather than what actually happened.
A single conviction for a crime involving moral turpitude committed within five years of admission, carrying a potential sentence of one year or more, is enough to make a lawful permanent resident deportable. Even when the conviction is decades old and the conduct is now constitutionally protected, the immigration system treats it as a valid conviction unless it has been formally vacated on the merits.
Expungement and Record Clearing
The path to clearing a legacy sodomy conviction varies by state. Some jurisdictions have enacted specific provisions allowing people convicted of conduct that has since been decriminalized to petition for expungement. Others require the person to go through the same general expungement process available for any criminal conviction, with waiting periods, filing fees, and judicial discretion. Court filing fees generally run a few hundred dollars, though total costs climb once attorney fees are included.
Anyone carrying an old sodomy conviction for consensual conduct should consult a criminal defense attorney in the state where the conviction was entered. The availability of relief depends heavily on local rules and judicial attitudes, and Lawrence did not automatically wipe the slate clean for people convicted before 2003.
