The League of Women Voters wants the Wisconsin Supreme Court to review an appellate decision that found the state's voter photo identification law is constitutional.
The league's attorneys filed a petition Friday asking the court to take the case. Three of the court's seven justices must vote to accept it. It's unclear when that vote might happen.
The league filed a lawsuit in October 2011 arguing the law creates an additional qualification for voters not contained in the Wisconsin Constitution and imposes such a burden it essentially denies people the right to vote. A Dane County judge found the requirements unconstitutional in 2012 but the 4th District Court of Appeals reversed him in May.
An injunction blocking the photo ID mandate in a separate challenge remains in place.
