This was an important statement because it put the problem not in the school buildings but in the act of separation. Even if the Mexican school had exactly the same textbooks, teachers of the same quality, buildings of the same size and condition — even granting all that — the segregation itself would still be a violation of equal protection. The Fourteenth Amendment’s requirement was not met by parallel institutions; it required shared institutions.
McCormick also addressed the educational argument that segregation proponents advanced about language acquisition. He found that segregating Spanish-speaking children from English-speaking environments actually harmed their English language development, because it limited their exposure to the language they were supposedly being prepared to use. If the goal were genuine English proficiency, separation from English-speaking environments was counterproductive. “Commingling” of students from different backgrounds was, in his view, necessary for building the common cultural foundation that American civic life required.
The district court ruling left open the question of what it meant for Plessy v. Ferguson. McCormick’s logic implied that the separate but equal doctrine was constitutionally inadequate — that equality required shared institutions, not parallel ones. But a district court judge could not overrule a Supreme Court precedent, and McCormick did not formally claim to do so. His ruling worked within the constitutional framework as it existed while pushing toward a conclusion that that framework had not previously produced.
## The Organizational Response
The filing of Mendez v. Westminster in March 1945 drew the attention of civil rights organizations that were watching the development of federal equal protection litigation as a potential tool for challenging segregation more broadly.
