WASHINGTON (AP) - Three years ago, the Supreme Court warned there could be constitutional problems with a landmark civil rights law that has opened voting booths to millions of African-Americans. Now, opponents of a key part of the Voting Rights Act are asking the high court to finish off that provision.
The basic question is whether state and local governments that once boasted of their racial discrimination still can be forced in the 21st century to get federal permission before making changes in the way they hold elections.
Some of the governments covered - most of them are in the South - argue they have turned away from racial discrimination over the years. But Congress and lower courts that have looked at recent challenges to the law concluded that a history of discrimination and more recent efforts to harm minority voters justify continuing federal oversight.
The Supreme Court could say as early as Monday whether it will consider ending the Voting Rights Act's advance approval requirement that has been held up as a crown jewel of the civil rights era.
The justices sidestepped this very issue in a case from Texas in 2009. In an opinion joined by eight justices, Chief Justice John Roberts wrote then that the issue of advance approval "is a difficult constitutional question we do not answer today."
Since then, Congress has not addressed potential problems identified by the court. Meanwhile, the law's opponents sensed its vulnerability and filed several new lawsuits.
The advance approval, or preclearance requirement, was adopted in the Voting Rights Act in 1965 to give federal officials a potent tool to defeat persistent efforts to keep blacks from voting.
The provision was a huge success, and Congress periodically has renewed it over the years. The most recent occasion was in 2006, when a Republican-led Congress overwhelmingly approved and President George W. Bush signed a 25-year extension.
The requirement currently applies to the states of Alabama, Alaska, Arizona, Georgia, Louisiana, Mississippi, South Carolina, Texas and Virginia. It also covers certain counties in California, Florida, New York, North Carolina and South Dakota, and some local jurisdictions in Michigan and New Hampshire. Coverage has been triggered by past discrimination not only against blacks, but also against American Indians, Asian-Americans, Alaskan Natives and Hispanics.
Before these locations can change their voting rules, they must get approval either from the U.S. Justice Department's civil rights division or from the federal district court in Washington that the new rules won't discriminate.
Congress compiled a 15,000-page record and documented hundreds of instances of apparent voting discrimination in the states covered by the law dating to 1982, the last time it had been extended.
