The State Supreme Court upheld a state voter ID law, Act 10, and the state's domestic partnership registry Thursday.
In a decision written by Justice Michael Gableman, he ruled that Act 10, the law that prohibits most collective bargaining between the government and public employees, does not violate the state constitution.
Despite the 4-3 ruling on voter ID, the law remains blocked in federal court.
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.
Justices considered whether that domestic partnership registry violates a constitutional amendment passed in 2006 prohibiting "substantially similar" institutions to marriage. Two lower courts said it does not. The justices upheld the constitutionality of the registry with a unanimous decision.
This case spans back to August 2009, when same-sex partners in Wisconsin could join a registry allowing them limited legal benefits as domestic partners. Months later, the conservative group Wisconsin Family Action filed suit saying that violated the amendment prohibiting "substantially similar" institutions to marriage.
