DENVER - Utah's same-sex marriage ban will be debated Thursday in front of a panel of federal appeals judges in Denver.
The three judges on the 10th Circuit Court of Appeals will hear arguments on whether they should uphold separate rulings by two federal judges who threw out same-sex marriage bans in Utah and Oklahoma.
Thursday, experts say pressure is on the judges at a time when polls show a majority of Americans backing same-sex unions. The judges picked at random to hear the case include two Republicans and one Democrat.
The plaintiffs counter there is little data backing up the state's case on parenting and that the ban improperly deprives gay couples of the right to marriage.
Arguments about Oklahoma's same sex marriage ban will be heard in Denver next week, but it could be months before the judges issue a ruling.
After that, the case could be appealed to the Supreme Court of the United States.
