Key legal question
How should the hypothetical income without invalidity be determined?
Extracted holding
The valid income had to be based on the likely income in 1995, at least CHF 66,950, adjusted for nominal wage development to at least CHF 77,536 for 2006.
Extracted reasoning
The decisive benchmark is not the last salary actually earned, but the income the insured would probably have earned without disability. The earlier, higher income from the pre-health-damage occupation was the relevant starting point, because the insured had ceased that work for health reasons and later earned even more in short-lived jobs lost because of the impairment.
