Kernrechtsfrage
Whether the cantonal court could base the hypothetical valid income on statistics instead of the last actual income of the self-employed insured person.
Extrahierter Entscheid
The valid income should in principle be based on the income the insured would probably have earned without disability; in this case the administration rightly relied on the IK entries, so no statistical substitution was justified.
Extrahierte Begründung
The bankruptcy was linked to the health-related interruption of work, not shown to have occurred independently of the illness. The insured had worked as a self-employed restaurateur for about five years, and there were no reasons to assume she would have changed to salaried work without disability.
