League of United Latin American Citizens v. Wilson
United States District Court for the Central District of California
908 F. Supp. 755 (1995)
California voters approved Proposition 187 in 1994, requiring law enforcement, social services, health care, and public-education personnel to verify and report certain individuals' immigration status and deny undocumented individuals social services, health care, and education - with schools specifically required to verify parents' immigration status, report it, and help transition undocumented children to schools in their home countries. The League of United Latin American Citizens and other plaintiffs sued Governor Pete Wilson and other state officials (defendants), seeking to enjoin enforcement of the initiative's provisions.
