SALT LAKE CITY — A federal appeals court restored Utah’s ban on polygamy Monday, handing a defeat to the family from TV’s “Sister Wives” and other polygamists who say the ruling could send plural families back into hiding out of fear of prosecution.

Others cheered the decision they say will help police prosecute people for crimes tied to the practice, such as underage marriage.

The 10th U.S. Circuit Court of Appeals dismissed a 2013 ruling that struck down key parts of Utah’s law against bigamy, or holding multiple marriage licenses. U.S. District Judge Clark Waddoups had found the state violated polygamists’ right to privacy and religious freedom.

The court ruled Waddoups should not have considered a lawsuit from Kody Brown and his four wives because they were never charged with a crime.
