What is Lawrence v. Texas (2003)?

Lawrence v. Texas (2003) is the Supreme Court decision that declared state criminal laws punishing private, consensual sexual conduct between adults of the same sex unconstitutional. The Court grounded its ruling in the Fourteenth Amendment's Due Process Clause, holding that "liberty" includes the right of adults to make intimate personal choices without government interference. In doing so, the Court overruled its own precedent, Bowers v. Hardwick (1986), which had upheld a similar Georgia law just 17 years earlier.

For AP Gov, Lawrence matters because it shows the Due Process Clause doing more than incorporating the Bill of Rights against the states. It also protects unenumerated rights, like privacy, that aren't spelled out anywhere in the Constitution's text. That's the same logic behind Griswold v. Connecticut and Roe v. Wade, and Lawrence extended it to LGBT Americans. The decision became a building block for later marriage-equality litigation, including Obergefell v. Hodges (2015).

Why Lawrence v. Texas (2003) matters in AP® Gov

Lawrence v. Texas lives in Unit 3: Civil Liberties and Civil Rights, specifically Topic 3.7 (Selective Incorporation & the 14th Amendment), supporting learning objective 3.7.A: explain the implications of the doctrine of selective incorporation. The essential knowledge here is that the Fourteenth Amendment's due process clause limits state regulation of civil liberties. Lawrence is a clean example of exactly that. Texas passed a criminal law, and the federal Constitution stepped in to block it. The case also demonstrates two bigger ideas the exam loves: the Court overturning its own precedent (Bowers), and the Due Process Clause protecting rights beyond the Bill of Rights' explicit text. Lawrence is not one of the 15 required SCOTUS cases, but it's strong outside evidence for argument essays about privacy, liberty, and federal limits on state power.

How Lawrence v. Texas (2003) connects across the course

McDonald v. Chicago (Unit 3)

Both cases use the Fourteenth Amendment's Due Process Clause to stop states from restricting individual liberty. The difference is what gets protected. McDonald incorporated an enumerated right (the Second Amendment), while Lawrence protected an unenumerated one (privacy in intimate conduct). Together they show the two jobs the Due Process Clause does.

Gitlow v. New York (Unit 3)

Gitlow started the selective incorporation story in 1925 by applying free speech protections to the states. Lawrence sits much further down the same road. Once the Court accepted that 'liberty' in the Fourteenth Amendment binds the states, it could extend that liberty to rights the framers never wrote down.

Mapp v. Ohio (Unit 3)

Mapp applied the Fourth Amendment's protection against unreasonable searches to the states, and the Lawrence case literally began with police entering a private home. Both cases reinforce the idea that the Constitution shields what happens in your home from state intrusion, one through search rules and one through substantive liberty.

Is Lawrence v. Texas (2003) on the AP® Gov exam?

Lawrence v. Texas is not one of the 15 required Supreme Court cases, so you won't be forced to analyze it in the SCOTUS comparison FRQ's required-case slot. Where it earns you points is as the non-required case in that FRQ (when the prompt centers on due process, privacy, or incorporation cases like McDonald v. Chicago) and as outside evidence in the Argument Essay on questions about civil liberties or the scope of the Fourteenth Amendment. On multiple choice, expect scenario stems where a state criminalizes private conduct and you have to identify which constitutional provision applies. The answer is the Due Process Clause of the Fourteenth Amendment, not the First Amendment and not the Equal Protection Clause. Knowing that Lawrence overruled Bowers v. Hardwick also helps with questions about stare decisis and how precedent can change.

Lawrence v. Texas (2003) vs Obergefell v. Hodges (2015)

Lawrence struck down criminal bans on same-sex intimacy in 2003; Obergefell legalized same-sex marriage nationwide in 2015. Lawrence is about decriminalizing private conduct under due process liberty, while Obergefell goes further and recognizes marriage as a fundamental right using both due process and equal protection. Think of Lawrence as the precedent Obergefell built on, twelve years apart.

No. Lawrence (2003) decriminalized same-sex intimacy; it said nothing about marriage. Same-sex marriage wasn't legalized nationwide until Obergefell v. Hodges in 2015, which built on Lawrence's due process reasoning.

What case did Lawrence v. Texas overturn?

Both use the Fourteenth Amendment's Due Process Clause against the states, but McDonald (2010) incorporated an enumerated right, the Second Amendment, while Lawrence protected an unenumerated right to privacy in intimate conduct. McDonald is a required AP Gov case; Lawrence is not.
