Kernrechtsfrage
Whether the clause reducing daily benefits by half after 180 days for psychiatric illness was binding on the insured.
Extrahierter Entscheid
The clause was objectively unusual and, in the circumstances, also subjectively unexpected; it could not produce legal effect against the insured.
Extrahierte Begründung
Such a reduction is not customary in Swiss sick-pay insurance and contradicts the insured's legitimate expectation of equal cover for bodily and mental illness. The court rejected the idea that the insured's medical training alone made him experienced enough to anticipate this insurance-specific restriction.
