Kernrechtsfrage
Whether the respondent was entitled to a whole disability pension based on the medical evidence
Extrahierter Entscheid
The cantonal judgment awarding the pension could not stand; the medical file had to be supplemented before a new pension decision could be made.
Extrahierte Begründung
The Federal Court held that the decisive question was whether the experts had adequately addressed the normative criteria for evaluating chronic fatigue syndrome and the respondent's remaining capacity for adapted work. Because this clarification was missing, further medical inquiry was necessary.
