Reed v. Reed (1971) was the first Supreme Court case to strike down a state law as unconstitutional sex discrimination, ruling that Idaho's automatic preference for men as estate administrators violated the Equal Protection Clause of the 14th Amendment.
Reed v. Reed (1971) started with an Idaho law that said when two equally qualified people wanted to administer a deceased person's estate, the man automatically won. Sally Reed challenged the law after it handed her son's estate to her ex-husband simply because he was male. The Supreme Court unanimously struck the law down, holding that an arbitrary preference based on sex violates the Equal Protection Clause of the 14th Amendment.
That made Reed v. Reed the first time the Court ever invalidated a law because it discriminated on the basis of sex. For nearly a century, the Equal Protection Clause had been used almost exclusively in race cases. Reed extended it to gender, and it gave the women's rights movement (especially groups like the National Organization for Women) a working legal strategy. Instead of waiting on legislatures, advocates could now challenge sex-based laws in court the same way the civil rights movement had challenged race-based ones.
Reed v. Reed lives in Topic 3.10 (Social Movements and Equal Protection) in Unit 3: Civil Liberties and Civil Rights. It directly supports learning objective AP Gov 3.10.A, which asks you to explain how constitutional provisions have supported and motivated social movements. The CED's essential knowledge says civil rights protect people from discrimination based on race, national origin, religion, and sex, and it names the women's rights movement and NOW as evidence of the Equal Protection Clause in action. Reed is the case that proves that point. It shows the equal protection clause isn't just a race-discrimination tool; it's a constitutional hook any social movement can use. That's the exact argument pattern the AP exam wants you to make about how the Constitution motivates movements.

Brown v. Board of Education (Unit 3)
Brown used the Equal Protection Clause to attack race discrimination; Reed used the same clause to attack sex discrimination seventeen years later. The women's rights movement deliberately copied the NAACP's playbook of winning rights through litigation.
National Organization for Women (Unit 3)
NOW is the CED's named example of the women's rights movement, and Reed v. Reed is the courtroom win that validated its strategy. After Reed, challenging sex-based laws under the 14th Amendment became the movement's main legal weapon.
Civil Rights Act of 1964 (Unit 3)
Reed shows the judicial path to equality while the Civil Rights Act shows the legislative path. Together they illustrate the CED's point that civil rights come from both the Constitution and acts of Congress.
Plessy v. Ferguson (1896) (Unit 3)
Plessy is what a failed equal protection reading looks like; Reed is part of the long arc of the Court reading the clause more broadly. Tracing Plessy to Brown to Reed gives you a ready-made story about how equal protection jurisprudence expanded over time.
Reed v. Reed is an illustrative example in Topic 3.10, not one of the required Supreme Court cases, so you won't be forced to brief it. But it shows up in multiple-choice questions that test whether you can connect a court decision to a social movement's strategy. Typical stems ask which case most directly influenced NOW's legal approach to sex discrimination, what constitutional argument the Court used to strike down Idaho's law (equal protection under the 14th Amendment), or how Reed marked a shift in the women's rights movement's tactics. On FRQs, Reed is a strong piece of evidence for any prompt about how constitutional provisions support social movements. The move to make: name the Equal Protection Clause, say Reed was the first case applying it to sex discrimination, and tie it to the women's rights movement.
Both cases rest on the Equal Protection Clause, so it's easy to blur them. Brown (1954) struck down racial segregation in public schools and is a required SCOTUS case you must know in depth. Reed (1971) struck down sex discrimination in a state law and is an illustrative example. The quick sort: Brown = race + required case; Reed = sex + first-ever gender equal protection win.
Reed v. Reed (1971) was the first Supreme Court case to strike down a law as unconstitutional sex discrimination.
The Court ruled that Idaho's automatic preference for men as estate administrators violated the Equal Protection Clause of the 14th Amendment.
Reed extended the Equal Protection Clause beyond race, showing it could protect against discrimination based on sex.
The decision validated the women's rights movement's litigation strategy, modeled on the civil rights movement's success in Brown v. Board.
On the AP exam, Reed is your go-to evidence for explaining how constitutional provisions motivate and support social movements (AP Gov 3.10.A).
In 1971, the Supreme Court unanimously struck down an Idaho law that automatically preferred men over women as estate administrators. It was the first time the Court invalidated a law for sex discrimination under the Equal Protection Clause.
No. Reed is an illustrative example in Topic 3.10, not one of the required cases like Brown v. Board. You won't be asked to brief it in a SCOTUS comparison FRQ, but it's excellent evidence for questions about social movements and equal protection.
Both used the Equal Protection Clause, but Brown (1954) addressed racial segregation in schools while Reed (1971) addressed sex discrimination in state law. Brown is a required case; Reed is the illustrative example showing the clause expanded to cover gender.
No. Reed struck down one arbitrary sex-based law, but it didn't ban all gender distinctions in law. Its significance is that it opened the door, establishing for the first time that the Equal Protection Clause applies to sex discrimination at all.
The CED names NOW as evidence of how the Equal Protection Clause supports social movements, and Reed proved that strategy works. After Reed, women's rights advocates could challenge sex-based laws in court using the 14th Amendment, just as the civil rights movement had done with race.
