Solution extraite
The insured failed to disclose relevant health impairment; the declaration that he was fully healthy was not credible.
Motifs extraits
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.
