MADISON, Wis. (AP) – The Wisconsin Supreme Court plans to rule on whether a 2009 law creating a domestic registry that provides limited benefits to same-sex couples is constitutional. The court was to issue its decision Thursday. It comes even as a challenge to the constitutional ban on same-sex marriages continues in federal court. A judge last month declared the ban unconstitutional, and the 7th Circuit Court of Appeals plans to hear arguments in that case on Aug. 26. If the court strikes down the registry, that decision could quickly become moot if the federal courts allow same-sex marriages in the state. But in the meantime, couples on the registry would lose the rights they currently enjoy thanks to the 2009 law.
