Keyes was the first school desegregation case decided by the Supreme Court that did not originate in a Southern city. Geography was its quintessence-not merely the line drawing and school assignment form-but its political geography and demography variant. In Denver, as was the case in most Southwestern cities, the number of Mexican Americans was as large or larger than the number of Black schoolchildren. In several important cases taken up at approximately the same time, Anglo community lawyers and NAACP Legal Defense and Educational Fund lawyers took up important cases in desegregation (Keyes v. School District No. I), bilingual education (Lau v. Nichols), and Texas school finance (San Antonio Independent School District v. Rodriguez) without significant formal involvement by lawyers representing Latino interests. In part, this Article argues, it was a traditional blind spot in the Black-White legal theory that doomed the cases; even though the Chinese American plaintiffs prevailed in Lau, it was undertaken without significant Latino legal involvement. In addition, the Mexican American Legal Defense and Educational Fund was not yet the major purposive legal organization it became in the next decade, when it won significant voting rights and immigrant education Supreme Court cases. However, it had already begun to undertake Tenth Circuit education litigation and was building its organizational capacity, and the failure of White lawyers in Denver and Texas to incorporate a Mexican American theory of the case contributed to an unsuccessful litigation strategy.
