State attorneys plan to review a 6th U.S. Circuit Court of Appeals decision upolding gay marriage bans in four states to determine whether the ruling has implcations for Utah's own same-sex marriage laws, an attorney general's office spokeswoman said Thursday.

"It's a complicated legal analysis, so it's not that easy to say," Missy Larsen said.

Gay marriage became legal in Utah in December 2013, when a federal district judge overturned the state's voter-approved ban on same-sex unions, ruling it unconstitutional. Utah lost an appeal of the decision to the 10th Circuit Court of Appeals, and sought a hearing before the U.S. Supreme Court.

That petition, which like the 6th Circuit case was based on a states' rights argument, was rejected Oct. 6, when the high court declined to hear any same-sex marriage-related cases. With that decision, same-sex marriage became legal in Utah.

The deadline to ask the Supreme Court to reconsider its decision on Utah's case was Friday. The state did not ask for a reconsideration, Larsen said.

More than half of Utahns oppose same-sex unions, as does The Church of Jesus Christ of Latter-day Saints, the state's dominant religion.
