INDIANAPOLIS - The full Indiana House is set Monday afternoon to begin considering a proposal to ban same-sex marriage in the state's constitution.
The move to the full House follows a panel of lawmakers' initial approval to move the measure forward last week.
House Minority Leader Scott Pelath, D-Michigan City, has proposed to delete the portion of the amendment that bans civil unions.
Any changes approved by the House could derail the amendment this year.
Two consecutive legislatures must approve the exact same wording for an amendment to be added to the state's constitution.
Supporters and opponents of the marriage amendment arrived at the Statehouse early Monday morning to lobby lawmakers.
"This is an issue of what the definition of marriage is. Everyone has the equal right to marry, but marriage by definition is the union of a man and a woman," said Peter Sprigg, of Family Research Council.
"We'll keep pulling all the way through March 14 at midnight," said Peter Hanscom, of Freedom Indiana. "We've already seen through this process some tricks the Legislature has played on us, and we won't lie down until we know for sure HJR3 is dead."
Under legislative rules, the House can't vote on the amendment Monday, but is expected to vote before the end of the week.
Fifty-one representatives would need to approve the proposed ban to move it to the Senate for a vote.
If both chambers approve, the constitutional amendment will appear on the November ballot.
