The Browns filed their lawsuit in July 2011, arguing Utah’s law violated their right to privacy. The family’s argument relied primarily on the 2003 U.S. Supreme Court decision that struck down the Texas law banning sodomy, which was celebrated by gay rights advocates. At the time, Utah Attorney General Mark Shurtleff responded that the bigamy law is different because it involves entire families, not just consenting adults.

A U.S. District Court judge has sided with the polgyamous Brown family, ruling that key parts of Utah’s polygamy laws are unconstitutional.

Judge Clark Waddoups’ 91-page ruling, issued Friday, sets a new legal precedent in Utah, effectively decriminalizing polygamy. It is the latest development in a lawsuit filed by the family of Kody Brown, who became famous while starring in cable TV channel TLC’s reality series “Sister Wives.” The show entered a fourth season at the end of the summer.

Statement from Kody Brown:

The entire Brown family is humbled and grateful for this historical ruling from the court today. Like thousands of other plural families, we have waited many years for this day. While we know that many people do not approve of plural families, it is our family and based on our beliefs. Just as we respect the personal and religious choices of other families, we hope that in time all of our neighbors and fellow citizens will come to respect our own choices as part of this wonderful country of different faiths and beliefs. There are so many families who have waited for so long for this ruling and, on their behalf, we can only say: thank you, Judge Waddoups, for your courageous decision. We want to particularly thank our lead counsel Professor Jonathan Turley who represented us through the criminal investigation and then led the fight against this law. We also want to thank the team of lawyers and students from George Washington, including our local counsel Adam Alba. We are so honored and blessed to have been able to serve as the vehicle for this milestone ruling. Professor Turley has pledged to defend this decision on appeal and we are equally committed to fight to preserve this great victory.

Waddoups’ ruling attacks the parts of Utah’s law making cohabitation illegal. In the introduction, Waddoups says the phrase “or cohabits with another person” is a violation of both the First and 14th amendments. Waddoups later writes that while there is no “fundamental right” to practice polygamy, the issue really comes down to “religious cohabitation.”
