TULSA, Okla. - Attorneys for a same-sex Tulsa couple seeking the right to marry in Oklahoma have filed a petition with the U.S. Supreme Court asking the court to take up their case.

The couple, Sharon Baldwin and Mary Bishop, sued Tulsa County Clerk Sally Howe Smith for failing to issue them a marriage license shortly after voters in Oklahoma approved a ban on same-sex marriage in 2004.

The 10th U.S. Circuit Court of Appeals sided with the couple last month, upholding a federal judge's ruling that found the ban unconstitutional. However, those rulings are on hold as the case moves through the courts, meaning same-sex couples haven't been allowed to marry in Oklahoma.

An organization representing Smith filed an appeal earlier this month to the U.S. Supreme Court.
