A recent Michigan Court of Appeals ruling classifies adultery as a felony punishable by life in prison, the Detroit Free Press reported.

"Technically, any time a person engages in sexual penetration in an adulterous relationship, he or she is guilty of CSC I," the most serious sexual assault charge in Michigan's criminal code, the paper reported.

Lloyd Waltonen received four years in prison after prosecutors successfully tried him on a little-used statue that makes a person guilty of first-degree criminal sexual conduct whenever "sexual penetration occurs under circumstances involving the commission of any other felony."
