A federal appeals court decision that struck down Oklahoma’s ban on same-sex marriage will be appealed to the U.S. Supreme Court, the legal group representing the Tulsa County court clerk announced on Friday.

Kerri Kupec, spokeswoman for the Alliance Defending Freedom, told The Oklahoman that the clerk will ask Supreme Court justices to review the July 18 decision by the 10th U.S. Circuit Court of Appeals. In that 2-1 decision, the court ruled that Oklahoma’s ban violates 14th Amendment guarantees of due process and equal protection under the law.

Mary Bishop and Sharon Baldwin, the Tulsa County couple who sued the court clerk when she refused to give them a marriage license, issued a joint statement Friday night.

“Although we aren’t surprised by the Alliance Defending Freedom's decision to appeal our victory from the 10th U.S. Circuit Court of Appeals, neither are we disappointed,” the couple said.
