Kernrechtsfrage
How should the insured person's valid income be determined?
Extrahierter Entscheid
The valid income was correctly based on the last salary earned in church employment, not on an earlier, better-paid administrative career.
Extrahierte Begründung
The court found no highly probable evidence that health reasons caused the career switch. Statements to the IV officer and the file supported a non-medical, life-related change of occupation; thus the last earned income was the proper benchmark.
