(AP) — Recent federal court rulings overturning state gay marriage bans will not prompt a civil rights organization to revive its challenge to Nebraska’s strict ban that forbids even same-sex civil unions. But gay marriage advocates are hoping the recent rulings will lead to U.S. Supreme Court to take on the issue and strike down such bans.

The American Civil Liberties Union, which sued Nebraska in 2003 over its same-sex union ban approved by voters in 2000, said Wednesday it does not plan another lawsuit in the wake of rulings striking down similar bans in Oklahoma and Utah.

But Ken Upton, an attorney for national civil rights organization Lambda Legal, says he thinks the U.S. Supreme Court “now has the appetite” to decide whether Nebraska and other state bans are constitutional.
