Before Judge McCormick’s decision was appealed to the U.S. Court of Appeals for the 9th Circuit in San Francisco, the different school districts involved in the litigation reacted in different ways. Westminster integrated its elementary schools for the 1946-1947 school year by placing grades 1-4 in Westminster Main and grades 5-8 in Hoover. Finally, the Mendez children were able to attend Westminster Main.
In April 1947, the U.S. Court of Appeals handed down a unanimous decision. While the Court of Appeals upheld Judge McCormick’s judgment, it did so only on the basis that the segregation violated California law. The Court’s opinion noted that the U.S. Supreme Court’s segregation decisions were not controlling in this case since there was no state law mandating segregation of Mexican-American children, and there were such state laws in the litigation decided by the nation’s highest Court. As Professor Strum indicates, “The Court of Appeals was only willing to say that Mexican-American children could not be segregated because the legislature had not decided that sending them to separate schools was state policy.”
The school districts involved chose not to pursue an appeal to the U.S. Supreme Court.
