A federal judge in Utah has struck down key parts of the state's polygamy laws.
U.S. District Judge Clark Waddoups said prohibiting polygamous cohabitation in Utah's 1973 statute is unconstitutional.
The restrictions were challenged by the polygamous family that stars on TLC's "Sister Wives."
The judge said the provision in Utah's law forbidding cohabitation with another person violates the First Amendment's freedom of religion.
While the ruling does not legalize multiple marriages, it means polygamist families who live together cannot be prosecuted.
