Key legal question
Whether the claimant's valid income should be based on statistical wages or on the likely actual income without disability
Extracted holding
The valid income had to be set at CHF 52,000, based on the income the claimant would probably have earned without disability, not on statistical wages.
Extracted reasoning
The decisive criterion is the income the insured person would probably earn without impairment. Since the claimant already earned CHF 30,907 part-time despite disability, it was more probable that she would have earned about double the half-time base salary if fully fit.
