A federal judge is issuing no immediate ruling after holding on hearing on whether Utah can prohibit plural marriage.
Kody Brown and his four wives, stars of the reality show "Sister Wives," claim the law is unconstitutional.
The Browns did not attend the hearing Thursday in Salt Lake City.
The hearing dealt with the legalities of due process and freedom of association.
The judge spent most of the time grilling a state lawyer on why he shouldn't throw out Utah's bigamy law. It's stricter than the laws in 49 other states -- most of them prohibit people from having multiple marriage licenses.
Utah makes it illegal to even purport to be married to multiple partners.
