The Mexican American Legal Defense and Educational Fund (MALDEF) joined the American Civil Liberties Union, the ACLU of Arizona, the law firm of Altshuler Berzon and the National Immigration Law Center (NILC) in filing a lawsuit in federal court today on behalf of Chicanos Por La Causa and Somos America challenging Arizona's new law ["Legal Arizona Workers Act", which uses the Basic Pilot Program] that threatens employers with permanent loss of business licenses based on invalid new state requirements.

..."Under federal law, participation in the Basic Pilot Program is voluntary. By requiring Arizona employers to use this program, the Legal Arizona Workers Act runs afoul of the Constitution and will subject all Arizona employees regardless of legal status - Latinos in particular - to potential discrimination based on their race, ethnicity, or national origin," said Kristina Campbell, Acting Los Angeles Regional Counsel and lead MALDEF attorney on the case...

They also claim that the BPP database has issues. I'm absolutely positive that that's all that MALDEF and the ACLU - two groups with the same indirect link to the Mexican government - are concerned about. I'm absolutely positive that they aren't just far-left, reflexive supporters of illegal immigration.
