He says it's down to protecting the former Ferrari driver from media intrusion.
“It was always about protecting private things,” Damm told German outlet LTO.
“We considered whether a final report about Michael’s health could be the right way to do this.
“But that wouldn’t have been the end of it and there would have had to be constantly updated ‘water level reports’ and it would not have been up to the family when the media interest in the story stopped.
“They [the media] could pick up on such a report again and again and as ‘and what does it look like now?’ one, two, three months or years after the message.
"If we then wanted to take action against this reporting, we would have to deal with the argument of voluntary self-disclosure.
“If it is not the person concerned himself but friends or acquaintances who disclose private information, it is not a case of ‘voluntary self-disclosure’ of privacy.
“Therefore, the data subject can defend himself against disclosure of private circumstances even if the information comes from an acquaintance.”
Schumacher's brother, Ralf, said 'life isn't fair' when recently asked about his sibling.
“Sometimes life isn’t fair, unfortunately. We have to accept it,” Ralf said.
“When I see his [Michael’s] kids, Gina-Maria and Mick, my heart smiles.
