Lawyers for an Oklahoma clerk who refused to grant a marriage license to a same-sex couple say marriage exists for its procreative potential and that the U.S. Supreme Court agrees.

The argument came in a brief filed Tuesday by lawyers for Tulsa County Court Clerk Sally Howe Smith. Oral arguments are scheduled for later this month in the 10th Circuit Court of Appeals in Denver.
