A proposal to amend the Indiana Constitution to ban gay marriage and civil unions is on its way to the state Senate.

The Republican-controlled Senate Judiciary Committee approved the measure Wednesday by a 7-3 vote along party lines.

GOP lawmakers rejected Democrats’ argument that banning civil unions could threatened the ability of employers to offer domestic partner benefits.

Indiana already has a law on the books that bans gay marriage, but amendment supporters want the constitutional change to protect it from being overturned by what they call ‘activist judges.’

The proposal has already been approved by the GOP-led House.

If it wins full passage this year, the measure would still have to be approved by the next legislature and then by Indiana voters in order for the state Constitution to be amended.
