Kernrechtsfrage
Whether expert Dr. A. had to be excluded for bias or prior involvement
Extrahierter Entscheid
No objective grounds established for disqualification; prior assessment in another proceeding and sharp criticism of earlier experts did not show bias.
Extrahierte Begründung
The prior 1997 report concerned a different proceeding and function; adverse opinions alone do not prove partiality, and there was no unsound or insulting conduct.
