MONTGOMERY, Ala. (AP) - A court ruling in Kansas could lead to Alabama enforcing part of its immigration law that has never been used. The 2011 law required people registering to vote in Alabama for the first time to present evidence of citizenship, such as a passport or Alabama driver's license. Alabama's chief election official, Republican Secretary of State Jim Bennett, says the requirement was not put into effect because of litigation over similar requirements in Kansas and Arizona. A federal judge in Kansas ruled last week that federal officials must help Kansas and Arizona enforce laws requiring new voters to document their U.S. citizenship. Bennett says no decision has been made yet on what to do in Alabama and that will depend, in part, on whether the Kansas ruling is appealed.
