A California appeals court overturned the rape conviction of a man who authorities say pretended to be a sleeping woman's boyfriend before initiating intercourse, ruling that an arcane law from 1872 doesn't protect unmarried women in such cases.

A panel of judges reversed the trial court's conviction of Julio Morales and remanded it for retrial, in a decision posted Wednesday from the Los Angeles-based court.

Morales had been sentenced to three years in state prison. He was accused of entering a woman's bedroom late one night after her boyfriend had gone home and initiating sexual intercourse while she was asleep, after a night of drinking.

The victim said her boyfriend was in the room when she fell asleep, and they'd decided against having sex that night because he didn't have a condom and he had to be somewhere early the next day.

Morales pretended to be her boyfriend in the darkened room, and it wasn't until a ray of light from outside the room flashed across his face that she realized he wasn't her boyfriend, according to prosecutors.

"Has the man committed rape? Because of historical anomalies in the law and the statutory definition of rape, the answer is no, even though, if the woman had been married and the man had impersonated her husband, the answer would be yes," Judge Thomas L. Willhite Jr. wrote in the court's decision. (MORE)
