He was crazy, probably a paranoid schizophrenic but functional, off and on. I would bet it was because of “privacy” rules or perhaps even some special bizarre German legislation preventing mental illness from being reported that they sent the report to him and not to his employer.
Europe
The right to data privacy is heavily regulated and actively enforced in Europe. Article 8 of the European Convention on Human Rights (ECHR) provides a right to respect for one’s “private and family life, his home and his correspondence”, subject to certain restrictions. The European Court of Human Rights has given this article a very broad interpretation in its jurisprudence. According to the Court’s case law the collection of information by officials of the state about an individual without his consent always falls within the scope of Article 8. Thus, gathering information for the official census, recording fingerprints and photographs in a police register, collecting medical data or details of personal expenditures and implementing a system of personal identification has been judged to raise data privacy issues.
Any state interference with a person’s privacy is only acceptable for the Court if three conditions are fulfilled:
The interference is in accordance with the law
The interference pursues a legitimate goal
The interference is necessary in a democratic society
