Craig v. Boren is the 1976 Supreme Court decision that created intermediate scrutiny, the standard federal courts still use to judge laws that treat men and women differently. By a 7-2 vote on December 20, 1976, the Court struck down an Oklahoma statute that let women buy low-alcohol beer at 18 while making men wait until 21. Justice William Brennan’s majority opinion held that sex-based classifications must serve an important governmental objective and be substantially related to achieving it.1Justia. Craig v. Boren, 429 U.S. 190 (1976)
The Oklahoma Law at the Center of the Case
Oklahoma defined “minor” one way for women and another for men. Licensed vendors could not sell beer of up to 3.2% alcohol by weight to any minor, but the statute defined a minor as a woman under 18 or a man under 21.1Justia. Craig v. Boren, 429 U.S. 190 (1976) An 18-year-old woman could walk into a store and buy the beer legally. An 18-year-old man could not. That three-year gap became the constitutional problem.
Oklahoma itself classified the beverage as “non-intoxicating.” That label would matter later, when the Court examined whether the sex-based cutoff actually did anything to advance the state’s stated goal.
How the Case Reached the Supreme Court
Curtis Craig, a man between 18 and 21, and Carolyn Whitener, a licensed beer vendor, sued in the U.S. District Court for the Western District of Oklahoma in December 1972.1Justia. Craig v. Boren, 429 U.S. 190 (1976) Craig argued the law denied him equal protection under the Fourteenth Amendment.2Congress.gov. Fourteenth Amendment – Equal Protection and Other Rights Whitener argued the statute injured her business: she had to either turn away paying customers or risk sanctions.
A three-judge district court sided with Oklahoma, finding the state’s arrest statistics on young male drunk driving sufficient to justify the distinction. Craig and Whitener appealed directly to the Supreme Court.
The case almost fell apart on the way there. Craig turned 21 during the litigation, which mooted his personal claim. The Court kept the case alive through Whitener under third-party standing. Because the statute was aimed directly at vendors and left her a choice between losing customers and facing penalties, she had a concrete economic injury. That injury, combined with the close link between her commercial interests and her customers’ equal protection rights, let her assert those rights on her customers’ behalf.1Justia. Craig v. Boren, 429 U.S. 190 (1976) The ruling became an important precedent for businesses challenging laws on behalf of their customers.
The Intermediate Scrutiny Test the Court Created
Before Craig, courts had no settled standard for sex discrimination cases. Rational basis review, the default for most legislative classifications, gave governments an easy win. Strict scrutiny, the demanding standard used for race, had fallen one vote short in Frontiero v. Richardson three years earlier, where a four-justice plurality wanted to treat sex as a suspect classification but Justice Powell and two others refused to preempt the Equal Rights Amendment then before the states.3Justia. Frontiero v. Richardson, 411 U.S. 677 (1973) Earlier still, Reed v. Reed (1971) had invalidated a sex-based Idaho probate rule but without announcing a new standard.4Justia. Reed v. Reed, 404 U.S. 71 (1971)
Craig filled the gap. Justice Brennan’s majority opinion announced a two-part test: a sex-based classification must serve an important governmental objective, and it must be substantially related to achieving that objective.1Justia. Craig v. Boren, 429 U.S. 190 (1976)
Each word does work. “Important” sits above the “legitimate” interest rational basis accepts and below the “compelling” interest strict scrutiny demands. “Substantially related” means a general social concern isn’t enough; the sex-based line itself has to meaningfully advance the goal. A loose connection fails.
The practical shift was large. Governments defending sex-based laws could no longer point to any plausible reason and prevail. They had to show a genuine link between treating men and women differently and a goal a court would recognize as genuinely important.
Why Oklahoma’s Statistics Failed the Test
Traffic safety was Oklahoma’s asserted goal, and the Court accepted it as important. The state’s defense fell apart on the second half of the test.
Oklahoma’s strongest evidence showed that 2% of men aged 18 to 20 had been arrested for driving under the influence, compared to 0.18% of women in the same range. The disparity was real, but the Court found it far too thin to justify a blanket sex-based ban. Treating maleness as a proxy for drunk driving on a 2% correlation was, in the Court’s words, an “unduly tenuous ‘fit.'”5Legal Information Institute. Craig v. Boren, 429 U.S. 190 (1976)
The methodology had deeper problems. None of the studies separated the effects of 3.2% beer from alcohol generally, which mattered because the state itself classified the beverage as non-intoxicating. Several surveys made no effort to connect their findings to the specific age-and-sex line at issue. Even if young men drank and drove more than young women, Oklahoma had not shown that barring men under 21 from buying weak beer reduced the problem.
The Vote, the Concurrences, and the Dissent
The Court reversed 7-2. Justice Powell joined the majority but wrote separately to call the case “relatively easy,” noting that the statistics did not justify a three-year sex-based age gap, especially one “so easily circumvented as to be virtually meaningless.” Justice Stevens concurred on different grounds, questioning whether tiered scrutiny made sense at all.5Legal Information Institute. Craig v. Boren, 429 U.S. 190 (1976)
Chief Justice Burger and Justice Rehnquist dissented. Rehnquist argued the Court should have applied rational basis review rather than invent a new tier, and that Oklahoma’s statistics were sufficient under that more deferential standard. The majority, he wrote, was creating a heightened standard without adequate constitutional justification.1Justia. Craig v. Boren, 429 U.S. 190 (1976)
What Craig v. Boren Means Today
Intermediate scrutiny has held up. Courts apply it not only to sex-based classifications but also to laws that distinguish based on whether a person’s parents were married at the time of birth.
The framework was strengthened in United States v. Virginia (1996), where the Court struck down the Virginia Military Institute’s male-only admissions policy. Justice Ginsburg’s majority opinion held that a defender of a gender-based government action must show an “exceedingly persuasive justification,” language that raised the bar above what the original Craig formula suggested. Virginia’s proposed alternative program for women fell well short of what VMI offered men.
The Court applied the same approach in Sessions v. Morales-Santana (2017), striking down a federal immigration provision that imposed different residency requirements on unwed mothers and fathers for passing citizenship to children born abroad. The government again failed to provide an “exceedingly persuasive justification” for the sex-based line, and the majority reaffirmed that such classifications are judged by today’s understanding rather than by the assumptions in place when the law was enacted.6Supreme Court of the United States. Sessions v. Morales-Santana, 582 U.S. 47 (2017)
Nearly five decades on, intermediate scrutiny remains the primary tool federal courts use when a law draws a line between men and women. It lets genuinely justified distinctions survive while catching those built on broad assumptions about how the sexes behave. A dispute over weak beer in Oklahoma became the foundation of modern sex discrimination law.
