Las Vegas is preparing for an appeals court's decision which could make Nevada the 20th state – in addition to the District of Columbia – to allow gay and lesbian couples to marry.

Nevada officials are no longer defending in court the state's 2002 voter-approved constitutional amendment limiting marriage to heterosexual unions, though a third party is.

Should the Ninth Circuit Court of Appeals – which heard arguments in a case challenging the ban earlier this week – strike down the ban as widely expected, only the state has standing to appeal the case to the U.S. Supreme Court.

Las Vegas NBC affiliate News 3 spoke with chapel owners about the possible change. While the network reported that none of the owners said they were preparing to turn away gay couples, it said the chapel owners “are struggling with their own moral dilemmas gay marriage presents.”

“I can only tell you what my heart says,” said Charlotte Richards, owner of The Little White Chapel. “I'm going to do what's right by God. And I am going to do what's right by the law.”

“I can see their tears and I see their hurt. And yes, there is a Lord and we're all going to answer to him. But if the law says you have to marry, then I'm going to follow what the state says also,” she added.

Ann Parsons from Vegas Weddings refused to discuss on camera her feelings on the issue.

“We don't really get involved with the whole legality,” she said.
