Kernrechtsfrage
Whether the original 2010 half disability pension could be reopened by reconsideration under Art. 53(2) ATSG.
Extrahierter Entscheid
Yes. The original pension decision was clearly incorrect because the invalidity assessment had been based on the wrong income comparison and wrong occupational assumption, and correction was significant.
Extrahierte Begründung
The court found no manifest error in the cantonal court's view that the insured would most likely have worked as a dance teacher rather than in office work; therefore the original comparison of earnings was clearly wrong.
