Latino parents living in Arizona asked the Tolleson Elementary School Board to allow their children to attend the white schools instead of the singular segregated school that was designated as the “Mexican school.” When they refused, Porfirio Gonzales, a Mexican American father of four, sued the school district on behalf of 300 families. The school district argued that Mexican American students could not speak English and required a separate school. Mexican American parents quickly demonstrated that their children were more than capable of speaking English. The courts decided that excluding Mexican American students and placing them all in one designated school, regardless of their abilities, violated their Fourteenth Amendment rights. They also found that a separate school made students feel a sense of inferiority. This hurt the development of a common cultural attitude which the courts thought was necessary for American public life. Gonzales won the case, and the courts ruled that the segregation of Mexican American students in a singular "Mexican School" was unconstitutional.
