400 students at Edgewood High School in San Antonio held a walkout and demonstration, and marched to the district administration office. Among the students’ grievances were insufficient supplies and the lack of qualified teachers. On July 10 of the same year, Demetrio Rodríguez and seven other Edgewood parents filed suit on behalf of Texas schoolchildren who were poor or resided in school districts with low property-tax bases. The resulting class action, Rodríguez v. San Antonio ISD, was a landmark case in which a federal district court declared the Texas school-finance system unconstitutional.
