The Brown family from Sister Wives could be at the forefront of a major legal victory in Utah as their polygamy case heads to an appeals court.

According to Fox News, the family is planning on asking a federal appeals court to uphold a prior ruling that decriminalized polygamy in the state of Utah, where they previously lived before facing prosecution in the state. That incident led to the family fleeing to Nevada.  

The appeal comes after the Utah Attorney General appealed the ruling, claiming it struck down key parts of the state law which banned the practice of polygamy. There aren't plans to charge Kody Brown or his wives--Meri, Janelle, Christine and Robyn--if the law is upheld, but attorneys argue that the law will help curb other crimes associated with the practice, like abuse and underage marriage.

The Browns won an initial victory in 2013 when U.S. District Judge Clark Waddoups found that a key part of the law, forbidding cohabitation, violated the family's rights to religious freedom and struck it down as a result. However, Bigamy, or holding multiple marriage licenses, is still illegal.  

The family's struggles with the ruling have not been covered on their reality show, which has instead focused more on their issues as a family and the personal lives of the adults and their kids.
