Utah same-sex marriage proponents want Supreme Court to rule, too

It's no coincidence that victors rarely ask for a rematch. When you've won, traditional wisdom says, walk away.

But for the Utah couples attempting to topple a state ban on same-sex marriage once and for good, there will be no turning back until their case -- or one like it -- lands at the U.S. Supreme Court.

Lawyers for the three plaintiff couples announced Thursday that they will join with Gov. Gary Herbert and Attorney General Sean Reyes in calling for the Supreme Court to hear their case.

It's an unusual move.

Utah asks Supreme Court for urgent intervention to halt same-sex marriage recognition

Utah asked the U.S. Supreme Court on Wednesday to issue an emergency order that would prevent the state from recognizing the marriages of thousands of gay and lesbian Utahns, because the state believes it will ultimately prevail in its fight to revive a ban on such unions.

If it does, the state wrote, Utah will do "everything possible" to enforce the law. That means effectively nullifying the more than 1,000 unions gay and lesbian Utahns entered into during a 17-day window when such weddings were legal.
