Hernandez v. Texas is the 1954 Supreme Court decision that extended the Fourteenth Amendment’s equal protection guarantee beyond a Black-and-white framework to cover any group a community singles out for different treatment. A unanimous Court, led by Chief Justice Earl Warren, threw out the murder conviction of Pete Hernandez after his lawyers showed that no person of Mexican descent had served on a Jackson County, Texas jury in twenty-five years. The ruling came down two weeks before Brown v. Board of Education and was the first Supreme Court case argued by a Mexican American legal team.1Justia U.S. Supreme Court Center. Hernandez v. Texas, 347 U.S. 475 (1954)
The Case Behind the Ruling
On October 11, 1951, an all-Anglo jury in Jackson County indicted Pete Hernandez for murder with malice and sentenced him to life in prison.2Library of Congress. 1954: Hernandez v. Texas His attorneys focused on a striking gap in the county’s civic life. Roughly 14 percent of Jackson County residents and 11 percent of adult men had Mexican or Latin American surnames, yet no one of Mexican descent had served on a jury commission, grand jury, or petit jury in the county for the previous twenty-five years.3Legal Information Institute. Hernandez v. State of Texas, 347 U.S. 475
The defense argued this pattern was systematic exclusion, not coincidence, and that it violated the Fourteenth Amendment. Texas disagreed. The case moved up through the state courts and reached the Supreme Court on the constitutional question: does equal protection reach discrimination against Mexican Americans at all?
The Two-Class Theory the Court Rejected
The Texas Court of Criminal Appeals upheld Hernandez’s conviction on what was known as the “two-class theory.” Under that reading, the Fourteenth Amendment’s equal protection guarantee addressed only discrimination between white and Black citizens. Texas classified Mexican Americans as white, so, the state reasoned, no unlawful discrimination could have occurred.2Library of Congress. 1954: Hernandez v. Texas
The theory created a convenient loophole. Jackson County treated Mexican Americans as white on paper while excluding them from public life in practice. Defining the group into the majority let the state deny them jury service and claim ethnicity had nothing to do with it.
The Evidence of Discrimination
To defeat the two-class theory, the defense had to show that Jackson County actually treated Mexican Americans as a group apart. The Supreme Court’s opinion collected the evidence:
- Children of Mexican descent were required, until shortly before the trial, to attend a segregated school for the first four grades. The superintendent said the children needed help with English, but the segregated classrooms combined two grades per teacher while the regular school gave each grade its own teacher.
- At least one restaurant in town displayed a sign reading “No Mexicans Served.”
- On the courthouse grounds, one men’s toilet was unmarked. The other was marked “Colored Men” and “Hombres Aqui” (“Men Here”).
The courthouse restrooms carried real weight in Warren’s opinion. The building where Hernandez was tried maintained separate facilities that grouped Mexican Americans with another excluded population.3Legal Information Institute. Hernandez v. State of Texas, 347 U.S. 475 Together with the twenty-five-year jury shutout and minimal participation in local business and civic groups, the record showed a community that excluded an entire ethnic group from public life while telling the courts no such exclusion existed.
What the Supreme Court Held
Chief Justice Warren wrote for a unanimous Court. The central holding was that the Fourteenth Amendment “is not directed solely against discrimination due to a ‘two-class theory’—that is, based upon differences between ‘white’ and Negro.”1Justia U.S. Supreme Court Center. Hernandez v. Texas, 347 U.S. 475 (1954) Equal protection was not limited to two racial categories. Whenever a distinct class of people exists and the law singles that class out without a reasonable basis, the guarantee applies.
The test the Court set was practical. A group did not need to fit an existing racial category to claim protection. If local conditions showed that a community treated a particular group as separate and inferior, that group qualified as a distinct class under the Fourteenth Amendment. The twenty-five years of jury exclusion, combined with the segregation evidence, established the systematic discrimination the Constitution prohibits.3Legal Information Institute. Hernandez v. State of Texas, 347 U.S. 475 The Court reversed the conviction and sent the case back for a new trial with a properly selected jury.
Why the Case Still Matters
Hernandez was decided on May 3, 1954, two weeks before Brown v. Board of Education.4Supreme Court Historical Society. Hernandez v. Texas (1954) Brown gets more attention, but Hernandez broke different ground. Brown addressed discrimination inside the established Black-white framework. Hernandez expanded the concept of who counts as a protected class in the first place, opening the Fourteenth Amendment to any group a community treats as separate and subordinate.
That flexible standard let other minority communities challenge discrimination they faced. By anchoring equal protection in observable social conditions rather than fixed racial labels, the Court gave the doctrine room to reach new forms of exclusion as they came into view. The principle remains good law.1Justia U.S. Supreme Court Center. Hernandez v. Texas, 347 U.S. 475 (1954)
The case also shaped jury selection law directly. Hernandez addressed the total exclusion of a group from the jury pool. Decades later, Batson v. Kentucky (1986) prohibited prosecutors from using peremptory strikes to remove individual jurors based on race. Between them, the two decisions cover equal protection at every stage of jury selection, from the pool to the final seated jury.5Justia U.S. Supreme Court Center. Batson v. Kentucky, 476 U.S. 79 (1986)
The lawyers who argued the case were Gus Garcia and Carlos Cadena of San Antonio and James de Anda of Houston, the first Mexican American team to argue before the Supreme Court.6Supreme Court Historical Society. Gus Garcia
What Happened to Pete Hernandez
The Supreme Court win did not end Hernandez’s legal troubles. With the original conviction overturned, he faced retrial in Jackson County, now with Mexican Americans eligible for jury service. On December 27, 1954, he pleaded guilty and received a twenty-year sentence, down from the original life term.2Library of Congress. 1954: Hernandez v. Texas The case that carries his name reshaped constitutional law; the man at its center went back to prison.
