By 1965 concerted efforts to break the grip of state disfranchisement had been under way for some time, but had achieved only modest success overall and in some areas had proved almost entirely ineffectual. The murder of voting-rights activists in Philadelphia and Mississippi, gained national attention, along with numerous other acts of violence and terrorism. Finally, the unprovoked attack on March 7, 1965, by state troopers on peaceful marchers crossing the Edmund Pettus Bridge in Selma, Alabama, en route to the state capitol in Montgomery, persuaded the President and Congress to overcome Southern legislators' resistance to effective voting rights legislation. President Johnson issued a call for a strong voting rights law and hearings began soon thereafter on the bill that would become the Voting Rights Act.
Congress determined that the existing federal anti-discrimination laws were not sufficient to overcome the resistance by state officials to enforcement of the 15th Amendment. The legislative hearings showed that the Department of Justice's efforts to eliminate discriminatory election practices by litigation on a case-by-case basis had been unsuccessful in opening up the registration process; as soon as one discriminatory practice or procedure was proven to be unconstitutional and enjoined, a new one would be substituted in its place and litigation would have to commence anew.
President Johnson signed the resulting legislation into law on August 6, 1965. Section 2 of the Act, which closely followed the language of the 15th amendment, applied a nationwide prohibition against the denial or abridgment of the right to vote on the literacy tests on a nationwide basis. Among its other provisions, the Act contained special enforcement provisions targeted at those areas of the country where Congress believed the potential for discrimination to be the greatest. Under Section 5, jurisdictions covered by these special provisions could not implement any change affecting voting until the Attorney General or the United States District Court for the District of Columbia determined that the change did not have a discriminatory purpose and would not have a discriminatory effect. In addition, the Attorney General could designate a county covered by these special provisions for the appointment of a federal examiner to review the qualifications of persons who wanted to register to vote. Further, in those counties where a federal examiner was serving, the Attorney General could request that federal observers monitor activities within the county's polling place.
Orange County must provide bilingual support in Spanish, Chinese, Korean and Vietnamese in compliance with federal law. The determination to provide ballot materials and support in these languages was issued in 2002 and were made using data from the 2000 U.S. Census under guidelines set forth in Section 203 of the Voting Rights Act.
