MADISON, Wis. (AP) – The Wisconsin Supreme Court has upheld a requirement that voters show photo identification at the polls, but the law remains blocked in federal court. Thursday’s ruling has no immediate impact given that the law was struck down in April by a federal judge in Milwaukee. His ruling is under appeal, and a federal appeals court would have to overturn it for the law to take effect. Four lawsuits have been filed over the law passed in 2011. The 4-3 Wisconsin Supreme Court ruling addressed two that were filed by the League of Women Voters and the Milwaukee branch of the National Association for the Advancement of Colored People. The voter ID requirement was only in force for one low-turnout spring 2012 primary before being blocked by a state judge.
