The Associated Press:

Two lesbians who are raising three children filed a lawsuit Monday to overturn Michigan's ban on adoption by unmarried couples.

April DeBoer, with two adopted children, and Jayne Rowse, with one, are longtime partners and nurses who live together with the kids in suburban Detroit. But under state law, they can't adopt them as a couple, an option available only to heterosexual married couples.

... The lawsuit names Gov. Rick Snyder and Attorney General Bill Schuette as defendants.

"We have not seen the suit yet, but our job is to enforce and defend all laws as enacted by the Legislature," Schuette spokesman John Sellek said. "Any changes to a law would have to originate in the Legislature."
