A polygamous family from TV's "Sister Wives" has filed a request for the U.S. Supreme Court to hear their case for legalizing polygamy.
Kody Brown and his four wives submitted their petition Monday.
They want the high court to review an appeals court's decision that upheld a unique provision of Utah's polygamy law that bans cohabitation with other partners even if the man is legally married to just one woman.
The ruling overturned a 2013 legal victory for the Browns in which a lower court ruled the law violated polygamists' right to privacy and religious freedom.
Like most polygamous families, Brown is legally married to one wife and "spiritually married" to the others.
The Browns, who now live in Las Vegas, face long odds. The U.S. Supreme Court has heard no more than 1 percent of the 7,500-plus cases appealed annually.
