BISMARCK, N.D.  — A Fargo lawmaker says federal court decisions to overturn bans on same-sex marriage in two conservative states may prompt challenges to North Dakota's constitutional ban on gay marriage.

Democratic Rep. Joshua Boschee is the first openly gay person elected to the North Dakota Legislature. He says a federal court decision in Oklahoma and one in Utah, resulting in those states' bans being struck down, may spur lawsuits in North Dakota.

North Dakota voters overwhelmingly approved a constitutional amendment in 2004 that bans same-sex marriages and defines marriage as the union of a man and a woman.

Boschee says he does not know of any pending lawsuits but he knows people who have expressed interest in challenging North Dakota law.
