Kernrechtsfrage
Whether the insured’s invalidity after 1 June 2005 had to be assessed under the ordinary income comparison method after he ceased self-employment.
Extrahierter Entscheid
Yes. Once the self-employed activity ended, the extraordinary method based on the former business activity lost its basis and the degree of invalidity had to be reassessed under the general comparison of incomes.
Extrahierte Begründung
The relevant change of circumstances in June 2005 triggered revision under Art. 17 LPGA. Because the occupational fields compared in the extraordinary method no longer existed, that method could no longer be applied.
