You can't get married if you're already married.
That's the legal loophole that has led Virginia authorities to drop bigamy charges against Charles Hicks. Court records show he was married to seven women over the last 40 years.

Officials say he got hitched three times while married to someone else. But under Virginia law, the marriages are invalid. Hicks later divorced wife number-five and officials say therefore, his marriage to wife seven is legal.

However, prosecutors say they may file additional charges.

The 61-year-old Hicks is a former Naval Postgraduate School administrator and now works for the Army Publishing Directorate.

Got it here.
I, for one, find this exceedingly interesting. Does this make Virginia's bigamy statute useless in that it's a law that's impossible to break?
