LANSING, Mich. — Michigan Democrats are calling for the state to act on legalizing same-sex marriage and making other legal changes in favor of marriage equality ahead of a U.S. Supreme Court ruling on the issue.

Democrats from the Republican-controlled state Senate and House said at a press conference Thursday that attitudes have changed in the decade since Michigan voters wrote a ban on same-sex marriage into Michigan’s constitution.

Rep. Jeremy Moss of Southfield is sponsoring a bill to allow a voter referendum to overturn that ban.

The U.S. Supreme Court is scheduled to hear testimony next month on the legality of bans on same-sex marriage in Michigan and three other states.

Moss says that even though he’s optimistic the high court will strike down the bans, Michigan should clean up its laws.

Spokeswoman Amber McCann says Republican Senate Majority Leader Arlan Meekhof wants to await the U.S. Supreme Court’s action.

On Wednesday, the GOP-led Michigan state House approved legislation allowing faith-based adoption agencies to refuse adoptions by same-sex couples if that violates the organization’s religious beliefs.
