Kernrechtsfrage
Whether the insured was entitled to a disability pension from 1 December 2002 because the somatoform pain disorder had become invalidating.
Extrahierter Entscheid
The disorder was not shown to have invalidating effect; the pension claim was rejected.
Extrahierte Begründung
The cantonal findings on the absence of a psychiatric comorbidity bound the Federal Court. Of the recognized criteria, only two were met; the missing criteria, especially loss of social integration in all life spheres and failure of appropriate treatment, prevented recognition of invalidity.
