The range of organizations filing amicus briefs in a district court case was itself notable. Amicus practice was less common in district court proceedings than in appellate courts; the presence of multiple organizations filing in support of the Mendez families at the district court level indicated how seriously the case was being taken across the civil rights organizational landscape.
## The School Districts’ Arguments
The school districts, defended by Orange County counsel Joel Ogle, made arguments that reflected the standard defensive repertoire available to segregated institutions in this period.
The jurisdictional argument was the most procedurally serious: Ogle contended that education was a state matter and that federal courts had no business adjudicating the enrollment decisions of California school districts. The federal-state relationship in education was genuinely contested in the 1940s, and the argument that federal courts lacked jurisdiction over school administration had legal substance, even if it was ultimately rejected.
The pedagogical argument was less defensible on its own terms. The districts maintained that separate schools for Mexican American children served a genuine educational need — that children who came from Spanish-speaking homes required a different instructional approach to acquire English and access the standard curriculum. This argument had a certain surface plausibility, rooted in the genuine reality that many Mexican American children did come from homes where Spanish was the primary language.
But the argument collapsed when confronted with the actual mechanism of student assignment. If the districts were sorting children by language need, they would have assessed language ability. They did not. They sorted by surname and appearance. Children who bore Spanish surnames and had dark complexions went to Mexican schools regardless of whether they spoke English. Children who bore European surnames and had lighter complexions went to Anglo schools regardless of their linguistic background. Soledad Vidaurri’s own children, the cousins who accompanied Sylvia and her brothers to the 17th Street enrollment, had lighter complexions and a partly French surname — and they were admitted. Sylvia and her brothers, with a Spanish surname and darker complexions, were turned away. No one had assessed anyone’s English proficiency.
