HELENA (AP) — Four gay couples are suing Montana over its constitutional ban on same-sex marriage.
That leaves North Dakota and South Dakota as the only two states with gay marriage bans and no lawsuits seeking to overturn them.
The Montana lawsuit was being filed Wednesday in federal court in Great Falls, with help from the Montana ACLU. It lists as plaintiffs four Montana couples who are either unmarried or were married outside the state.
The lawsuit alleges the ban denies same-sex couples the freedom and dignity afforded to other Montanans, and denies them the state and federal legal protections and benefits that come with marriage.
State marriage bans have been falling around the country since the U.S. Supreme Court last year struck down part of the federal Defense of Marriage Act.
