Questione giuridica chiave
Whether the insured established a disabling loss of earning capacity warranting a disability pension.
Decisione estratta
No legally relevant invalidity was shown; the medical evidence did not establish a disabling incapacity to work on the balance of probabilities.
Motivazione estratta
Somatoform pain disorders and similar syndromes usually do not cause lasting incapacity. The record did not show the exceptional criteria needed to make work resumption unreasonable, and the later deterioration was explained by work-related overstrain and thus by non-insurance-related psychosocial factors.
