Questione giuridica chiave
Whether the medical findings on residual work capacity were arbitrary or violated the duty to investigate.
Decisione estratta
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.
Motivazione estratta
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.
