An Indiana Senate panel on Monday will consider a measure which seeks to put a gay marriage ban in the state's constitution.

Before approving House Joint Resolution 3 (HJR-3) last month, the House stripped out language which also banned civil unions and other similar arrangements.

After the House vote, Senate President Pro Tem David Long announced that the measure would not be vetted in the Senate Judiciary Committee as he previously had said. Instead, the proposal will be heard in the Senate Rules Committee, which he chairs.

Long told the AP that he would “like to see a clean bill come to the floor for the Senate.”

“I will say that once it comes to the floor, any and all amendments are going to be considerable and available. There will be no attempt to block anything. There will be a full and robust discussion,” he said.

Freedom Indiana, the coalition working to derail the proposed ban, called on supporters to wear red at Monday's hearing.

Marriage equality foes want the Senate to restore HJR-3's original language.

“We'll be working with the Senate to restore the second sentence,” Curt Smith, president of the Indiana Family Institute, told the Courier Journal. “Retaining the second sentence makes the first sentence much more likely to survive a legal challenge.”

“Urge the Indiana Senate to restore the removed language of #HJR3 and pass the original version of the bill,” tweeted Brian Brown, president of the National Organization for Marriage (NOM).

Altering the proposed ban's language would likely keep it off this year's ballot, because before an amendment can head to voters, it needs to pass the General Assembly in two consecutive two-year sessions. If the House and Senate agree to the measure as altered, the earliest the modified amendment could reach voters is 2016.
