New challenge to Indiana's gay marriage ban

Indiana's ban on same-sex marriages faces a new challenge, in a lawsuit filed by a national gay rights group. Lambda Legal is representing three lesbian couples from Whitestown, Chesterton and Munster Indiana. The suit argues 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 in southern Indiana. The suits follow Indiana's legislative debate this year on adding the gay marriage ban to the state constitution and court rulings striking down such bans in Kentucky and other states. Indiana Attorney General Greg Zoeller has said he'll defend the state's marriage laws.
