The Browns—the polygamist family at the center of TLC’s reality show “Sister Wives”—found a legal happy ending when a federal judge in Utah struck down portions of the state’s anti-bigamy law.

The Browns sued in 2011 with pro bono assistance from George Washington University Law School professor and civil liberties attorney Jonathan Turley. Heading the family is Kody Brown, who is legally married to one woman but also lives with three additional women as his spiritual wives. Together, the family has 17 children.
