A much-anticipated lawsuit challenging North Dakota's same-sex marriage ban was filed on Friday, meaning that there are now no states in the union with unchallenged bans on same-sex marriage. Seven couples are challenging the state ban, along with its ban on recognizing legal, out-of-state same-sex marriages. North Dakota was one of several states to pass constitutional amendments by voter referendum in 2004 that limited or eliminated marriage rights for same-sex couples.
The Washington Post confirmed that the suit was imminent late in May. Given that a few challenges to state bans are already pending a decision from federal appeals courts, the North Dakota suit serves more of a symbolic purpose than anything else: it leaves no state ban unchallenged. The lawyer representing the North Dakota plaintiffs is Joshua Newville, who also recently filed suit on behalf of same-sex couples in South Dakota.
The complaint argues that "the state will incur little to no burden in allowing same-sex couples to marry and in recognizing the lawful marriages of same-sex couples from other jurisdictions on the same terms as different-sex couples," and follows the lead of other challenges to state bans by asserting that North Dakota's amendment violates the Equal Protection clause in the U.S. Constitution.
