Questione giuridica chiave
Whether the insured was entitled to more than a quarter invalidity pension based on the expert psychiatric assessment.
Decisione estratta
The expert report supported only a 40% loss of earning capacity, corresponding to a quarter pension, not a 60% invalidity degree.
Motivazione estratta
The psychiatrist found a 40% incapacity in any activity since October 2002; the somatoform pain disorder was not shown to increase incapacity. The cantonal court therefore misapplied federal law by granting a higher degree of invalidity.
