Key legal question
Whether the insured person's work capacity in a suitable activity was sufficiently established for pension assessment.
Extracted holding
The medical file was not sufficiently clear and consistent to determine the residual work capacity reliably; an expert medical assessment was required.
Extracted reasoning
The doctors' statements contained inconsistencies regarding whether the insured person could work 100% or only 75% in the general labor market, so the pension entitlement could not be finally assessed on that basis.
