Lawyers for Tulsa County clerk Sally Howe Smith are appealing a federal judge's ruling that says Oklahoma's amendment banning same-sex marriage is unconstitutional.
They filed a three-page notice of appeal on Thursday.
Howe-Smith was named a defendant in the case after she refused to issue a marriage license to a gay couple.
The judge said when he made the ruling it wouldn't go into effect immediately, because he expected it to be appealed.
An attorney representing the Tulsa County court clerk over a federal judge's ruling that Oklahoma's ban on gay marriage is unconstitutional says arguments for the appeal will likely be filed in the next few months.
