Until this week, sex between unmarried people in Utah was technically illegal, a vestige of earlier times.
That changed Wednesday, when Gov. Gary Herbert signed a bill that decriminalizes sex outside of marriage in the state. The bill was one of 119 he signed that day, spokesperson Anna Lehnardt tells NPR.
Utah was among only a few states that retained these laws.
State Senate Minority Leader Karen Mayne sponsored the bill and tells NPR that it was just a small piece in Utah's criminal code that needed to be revamped. "You hear all over the U.S. how you have antiquated laws about horses in the streets and all kinds of things, so we wanted to make them modern-day, in the now," Mayne says.
The measure also modifies criminal offenses.
State Rep. Paul Ray called the 1973 fornication law unenforceable, according to The Associated Press. But some lawmakers did not want it repealed on moral grounds.
"Personally I don't know if anyone ever worried about this," Emily Anderson, a senior at the University of Utah and the editor in chief of its newspaper, The Daily Utah Chronicle, tells NPR.
The fornication law was really just something that people joked about in class and on Twitter, she says. "Basically just like, 'Oh thank God, I can do this thing I've always been doing.' "
The law had not been prosecuted for years, according to a Utah website covering policy.
In a 1991 Deseret News report, an unmarried woman was quoted as saying she had "real concrete fear of criminal prosecution" for breaking the fornication law. "I am aware that last year another person in Salt Lake County was criminally prosecuted for such conduct," she said in a lawsuit filed that year.
