INDIANAPOLIS — Indiana's ban on same-sex marriages faces a new challenge in a lawsuit filed by a national gay rights group.
The federal lawsuit was filed by Lambda Legal on behalf of three lesbian couples from Whitestown, Chesterton and Munster. The suit the group announced Thursday argues that the couples' equal protection rights are being violated because they can't marry in Indiana and the state won't recognize same-sex marriages performed elsewhere.
A similar lawsuit was filed last week by four couples from southern Indiana.
The lawsuits follow Indiana's legislative debate this year on adding the gay marriage ban to the state constitution, a federal ruling overturning Kentucky's ban on recognizing same-sex unions, and related rulings in other states.
Indiana Attorney General Greg Zoeller has said he'll defend the state's marriage laws.
