Kody Brown and his four wives are continuing their process to appeal for legalized polygamy in their initial home state of Utah.  

The family, who star on the TLC show Sister Wives, are taking their case to a new level, according to reports, as they seek out the Supreme Court of the United States as they continue their battle against the state of Utah.  

According to Fox News, U.S. Supreme Court Justice Sonia Sotomayor had granted the family an extension to file a petition to the court to review their case, and they have until Sept. 10 to do so.  

The family's move comes after it was determined back in April that the family couldn't sue Utah, which put the family under investigation for bigamy after their reality show began airing on TLC, prompting them to relocate to Las Vegas, Nevada to avis prosecution. They claimed the state's ban on plural marriages infringes on their religious freedom and right to privacy. However, they were told they didn't have a case because they never actually faced charges, and prosecutors said they wouldn't go after consenting adults who had multiple wives.  

The decision reversed an earlier ruling which removed the threat for polygamous families, after a judge decided that the chance of being proescuted was what drove the Brown family to flee the state, and that key portions of Utah's law violated their right to privacy and religious freedom.  

Kody and his wives-Meri, Janelle, Christine and Robyn all star on their show, and changed things around regarding their legal status two years ago, when Kody and Meri divorced so he could legally marry Robyn instead and fully adopt her three children from a previous marriage. That then led to Meri seeking out an online affair with someone she believed was a man named Sam, but who turned out to be a Catfisher, named Jackie Overton.  

It is unclear if the show will be renewed for an eighth season.
