Despite pleas from Indiana’s business leaders, the Senate voted 40-10 last week in favor of a Constitutional amendment banning gay marriage, according to The Indianapolis Star. Gay marriage is currently banned in Indiana by statute.

The Indiana House has already approved the ban, which is as far as the measure will go this year. To amend its constitution, Indiana law requires that amendments be approved in the House and Senate two times, and the second vote must follow an election. That means the measure must pass again in either the 2013 or 2014 legislative session. Finally, the amendment must be placed on the ballot and approved by a majority of Indiana voters.
