A federal judge in Michigan could rule as soon as Thursday on a challenge to the state's ban on same-sex marriage and civil unions. The challenge comes as the U.S. Supreme Court is set to hear two cases dealing with gay marriage later this month.
In the Michigan case, a lesbian couple sued not because they want to be married, but because they want to be parents.
The Obama administration has filed a friend of the court brief urging the U.S. Supreme Court to strike down California's ban on gay marriage as a denial of "equal protection under the law." But the brief does not call for the abolition of all state bans on same-sex marriage.
The case now before the high court tests the constitutionality of California's Proposition 8, a referendum narrowly passed by voters in 2008 that reinstituted a ban on gay marriage.
