A misconduct allegation under section 107 StVG must be concrete and traceable.
The misconduct catalogue is exhaustively governed in section 107 StVG. Conduct outside that catalogue cannot give rise to a disciplinary sanction. The accused person has the right to know exactly which conduct is alleged so that they can respond to it.
What to do now: First, demand the written notice of allegation and check whether the alleged conduct is listed in section 107 StVG. Second, ensure that the facts are clearly and completely described. Third, if the legal basis is absent or unclear raise an objection immediately and seek legal advice.
