Kernrechtsfrage
Whether the medical findings on residual work capacity were arbitrary or violated the duty to investigate.
Extrahierter Entscheid
The cantonal findings on an 80% capacity for light work were not shown to be manifestly incorrect, but further clarification was required regarding the economic side of the assessment.
Extrahierte Begründung
The medical reports were comprehensive and the subjective complaints could not be objectively confirmed; however, the court had to clarify tax-recognized professional expenses under the duty to investigate before excluding a deviation from the individual account entries.
