SALT LAKE CITY (AP) -- A federal judge has scheduled arguments later this month on whether the stars of "Sister Wives" can continue challenging Utah's polygamy ban even though they won't be charged under it.
Police in Lehi opened an investigation on Kody Brown and his four wives after the reality TV show debuted in 2010. The Browns later sued, saying Utah's bigamy law violated their right to privacy.
Utah County prosecutors announced last month that they were closing the case without charging the family. They also said they have adopted a policy to not charge consenting adults in polygamous relationships unless they commit some other crime.
The Browns' suit against Utah County, the governor and state's attorney general claimed Utah's bigamy statute violates their constitutional rights to due process, equal protection, free exercise of religion, free speech and freedom of association.
