Kernrechtsfrage
Whether the MEDAS expert opinion was biased because the clinic was financially dependent on the invalidity insurance and thus could not be relied on.
Extrahierter Entscheid
The objection was procedurally inadmissible because it was raised for the first time before the Federal Court; in any event, repeated appointment as an expert is not by itself a ground for recusal.
Extrahierte Begründung
Challenges to impartiality must be made timely and specifically. The alleged institutional dependence of a medical expert centre does not establish bias as such, and no specific recusal ground against individual experts was shown.
