It is illegal to falsely defame a woman's chastity.

The Law Explained

A relic from a much more puritanical era, this statute made it a criminal misdemeanor to spread rumors about a woman's purity or sexual history. It was designed to protect the reputations of unmarried women in small pioneer towns where a vicious rumor could ruin marriage prospects. Though mostly superseded by modern civil defamation laws, the specific criminal charge existed for decades.
