Kernrechtsfrage
Whether the pension had to be recalculated already from 1 September 2008 after resuming self-employment.
Extrahierter Entscheid
The request was unfounded because the change in invalid earnings had to be taken into account only from 1 December 2008.
Extrahierte Begründung
Under Art. 88a(2) IVV, the effect of the change in the insured person's earning situation after starting self-employment on 1 September 2008 could only be considered after the relevant waiting period.
