The Ohio Supreme Court has dismissed a legal challenge to a proposed constitutional amendment which would legalize gay marriage.

The proposed amendment filed by Freedom to Marry Ohio would repeal a constitutional amendment defining marriage as a heterosexual union, which passed in 2004 with overwhelming support, and replace it with one which would allow gay marriage.

The Ohio Campaign to Protect Marriage, the group behind the ban, had claimed that Ohio Attorney General Mike DeWine should not have verified the proposed amendment's summary, arguing that the petition summary is invalid because “it is not a summary and is not a fair and truthful statement of the proposed constitutional amendment.”

While DeWine opposes equal marriage rights for gay couples, he asked the Republican-dominated court to dismiss the case.

“When somebody wants to put something on the ballot, it's not a question of whether Mike DeWine likes it or doesn't like it,” he told WKSU. “The question is: Is it a concise and accurate representation of what that ballot initiative would do. And our lawyers looked at it and said, 'Yes it was.'”

The group now must collect roughly 385,000 valid signatures from at least half of Ohio's 88 counties to get the proposal on next year's ballot.
