The Oklahoma Supreme Court has upheld a voter ID law in the latest battle in the U.S. between advocates who say the laws are aimed at suppressing voter turnout, and conservatives who say the protections are needed to prevent election fraud.
The Oklahoma court's Tuesday ruling says the state constitutional amendment approved by voters in 2010 is a "reasonable" regulation and not an undue burden on voters.
The lawsuit by voter Delilah Gentges was filed in 2012 after the law took effect.
