The American Civil Liberties Union is asking a judge to force the state of Michigan to recognize more than 300 same-sex marriages performed in March.
The ACLU filed a lawsuit Monday on behalf of couples who say their constitutional rights are being violated by Gov. Rick Snyder. He won't recognize the marriages for the purpose of benefits until federal courts decide the status of Michigan's ban on gay marriage.
More than 300 couples were married in the hours after a judge struck down the ban on March 21. But the decision was suspended by a federal appeals court the next day while it takes an appeal from the state.
The federal government is recognizing the same-sex marriages.
An email seeking comment was sent to Snyder's spokeswoman.
