Kernrechtsfrage
Whether the insured had violated the duty to disclose relevant health conditions when signing the health declaration for the higher indemnity cover.
Extrahierter Entscheid
The insured failed to disclose relevant health impairment; the declaration that he was fully healthy was not credible.
Extrahierte Begründung
The lower courts' finding of a gradual deterioration, known performance weakness, and inconsistencies about work capacity was not manifestly incorrect; the insured had to disclose the condition regardless of his personal assessment.
