16 year old boy sues his own mother for hacking his Facebook account

The relation between kids (especially teenagers) and their parents can get a bit testy sometimes, but you expect all such disagreements to be resolved in the privacy of your own home. What happens when a 16 year old files a case against his own mother for invasion of his privacy and hacking his online account, and the mother fights back claiming that till he is an adult, she is responsible for his well being. Well, as a judge, you would wish that you do not get such cases that are moral problems, and where any decision could be challenged (link to article):

A 16-year-old boy from Arkansas is suing his mother for harassment, claiming that she hacked his Facebook account and posted slanderous remarks, according to Arkansas TV station KATV Thursday. The mother, Denise New, denied the charges, claiming that her son left his Facebook page open on her computer and that she was entitled to take over his account because he had posted incriminating information on his Facebook page.
"Oh yeah, I'm going to fight it. If I have to go even higher up, I'm going to. I'm not gonna let this rest. I think this could be a precedent-setting moment for parents," she told KATV-TV. "You're within your legal rights to monitor your child and to have a conversation with your child on Facebook whether it's his account, or your account or whoever's account."
