Brief In OK Gay Marriage Ban Lawsuit Expected

Attorneys face a Monday deadline to file a brief outlining their appeal of a federal judge's ruling that overturned Oklahoma's ban on same-sex marriage.

The brief on behalf of a Tulsa County Clerk is expected to lay out arguments in defense of the ban in the 10th Circuit Court of Appeals.

Two Tulsa couples are fighting Oklahoma's voter-approved gay marriage ban. U.S. District Judge Terence Kern ruled last month that the ban violates the U.S. Constitution's Equal Protection Clause because it precludes same-sex couples from receiving an Oklahoma marriage license.

Oral arguments are scheduled to start April 17.

Kern's ruling is one of several in the past few months to strike down or void part of such a ban. The 10th Circuit is hearing a similar appeal out of Utah.
