"A German couple are not liable for the filesharing activities of their 13-year old son because they told him unauthorized downloading and sharing of copyrighted material was illegal, and they were not aware the boy violated this prohibition, the German Federal Court of Justice ruled on Thursday. ... The ruling of the Federal Court of Justice reversed a ruling of the higher regional court of Cologne, which found the parents were liable for the illegal filesharing because they failed to fulfill their parental supervision. That court said the parents could have installed a firewall on their son's computer as well as a security program that would have made it possible to only allow the child to install software with the consent of his parents. Besides that, the parents could have checked their son's PC once a month, and then the parents would have spotted the Bearshare icon on the computers' desktop, according to the Cologne court. 'The Federal Court overturned the decision of the Appeal Court and dismissed it,' the court said."
