The Alabama Attorney General’s Office has opened yet another front in the legal battle to scale back the 1965 Voting Rights Act. With a lawsuit filed this week in Washington, D.C., add Alabama to the growing list of governments complaining to judges that they’re chafing under the burdens of the 47-year-old law that doesn’t let them run their elections without strict supervision. All or part of 16 states — those with a blatant history of discrimination against minority voters — have to get permission from the federal government before they change any election-related procedures. Alabama is one of those states. “The fact that so many covered states are now willing to come out against the Voting Rights Act is a sea change since the act’s amendments passed 98-0 in the Senate in 2006,” said Rick Hasen, professor at the University of California Irvine School of Law and election law expert. Congress approved a 25-year extension of the law in 2006 and, as with previous renewals, sparked a new round of legal action. Shelby County has a case pending at the U.S. Supreme Court, as does a jurisdiction in North Carolina. And other states from around the South have challenges at various stages in the legal process.
