Answer:
Segregation of Mexican American children in schools would violate both California Law and Federal Law.
Step-by-step explanation:
In Mendez vs Westminster, the Supreme Court ruled, 8 years before Brown vs Board of Education, that segregated schools were unequal. The Court primarily relied on evidence that Mexican American children were having problems to learn english because of lack of exposure.
In Brown vs Board of Education, the SCOTUS finally prohibited segregated schools accross the United States, because the Court considered that said schools were inherently unequal even if they equal in quality (facilities, teachers, materials), thus, they were a violation of the equal protection clause of the 14th Amendment.
Segregated schools are forbidden by law in any state.
