Proposition 187 is introduced to deny illegal immigrants (or those suspected of being so) health care, social services, and public education. In November of 1994, the issue was brought to the voters, where it received 59% of the votes in its favor, and became a law. Its constitutionality was immediately challenged and three days after Election Day, a temporary restraining was placed on the new law. In March of 1998, U.S. District Court confirmed that the federal government has exclusive authority of immigration policies and thus, the law was unconstitutional. This court ruling effectively killed the law.
