BISMARCK (AP KFGO-AM) -- Seven couples have filed a federal lawsuit challenging the ban on same-sex marriage in North Dakota, the last remaining state without a court challenge.
It challenges both North Dakota's constitutional ban on gay marriage and its refusal to recognize marriages of same-sex couples who legally wed in other states.
The lawsuit means cases are currently pending in all 31 states with gay marriage bans. Judges have overturned several of those bans since the U.S. Supreme Court struck down part of the federal Defense of Marriage Act last year.
Minneapolis-based attorney Josh Newville, who is representing the North Dakota couples, also filed a lawsuit on behalf of South Dakota couples in May.
