The U.S. Supreme Court's decision in a gay marriage case from California doesn't have an immediate impact on Michigan's voter-approved ban.
The court didn't make a sweeping statement on the legality of gay marriage Wednesday. It let stand a trial judge's decision that the California ban is unconstitutional.
Michigan's 2004 gay marriage ban is being challenged in Detroit federal court. Judge Bernard Friedman heard arguments in March but said he would wait for guidance from the Supreme Court before making a decision.
The American Civil Liberties Union says key parts of another Supreme Court opinion on a federal marriage law could help it defeat Michigan's ban in Friedman's court.
Attorney General Bill Schuette, who supports the ban, says states have the power to define marriage.
