Kernrechtsfrage
Whether the cantonal court violated the investigation principle by denying further medical inquiries despite indications of psychiatric or intellectual impairment.
Extrahierter Entscheid
Yes. Given the long psychiatric treatment history and other indications, the file required further assessment of the insured person's mental and psychological condition.
Extrahierte Begründung
The absence of a formal ICD-10 diagnosis did not by itself justify waiving additional evidence. The record contained significant indications of a health impairment with disease value, including years of psychiatric treatment and BEWA observations. The cantonal court relied too heavily on anticipatory assessment.
