MADISON, WI (WTAQ) - A Wisconsin appeals court says the law is constitutional.
Back in October of 2011, the League of Women Voters filed a lawsuit in Dane County Circuit Court challenging the law.
On Thursday, the 4th District Court of Appeals said the league failed to prove that the law is unconstitutional.
Another Dane County judge's decision blocking the requirement in a separate lawsuit still stands.
There are also two federal lawsuits challenging the law as well.
