Kernrechtsfrage
Whether the insured had an invalidating health impairment entitling him to an IV pension.
Extrahierter Entscheid
No invalidating impairment was shown; the somatoform pain disorder was considered medically and legally surmountable.
Extrahierte Begründung
The medical file showed no somatic findings significantly limiting work capacity. The psychiatric report found a somatoform pain disorder but no qualifying psychiatric comorbidity or other exceptional criteria making pain coping unreasonable.
