SAN FRANCISCO (CBS/AP) — A federal appeals court is set to consider gay marriage bans in Idaho, Nevada and Hawaii.

The 9th U.S. Circuit Court of Appeals has scheduled two hours of arguments Monday on whether such bans should be struck down in Idaho and Nevada.

Hawaii legalized gay marriage in December so that appeal may be dismissed.

The appeals court has previously ruled in favor of gay marriage.

Supporters of bans argue that states have an interest in promoting marriage between a man and a woman, which they say is optimal for child-rearing.

Opponents of bans counter that there is no data supporting the child-rearing contention and they argue that the marriage prohibitions are unconstitutional.

The arguments are the latest at the federal court level where same-sex wedding proponents have gained numerous victories.
