Key legal question
Whether, in revising the invalidity pension, the income without invalidity had to be based on the last salary or on statistical wage data because the last employer later went bankrupt.
Extracted holding
The last salary remained the proper basis; a later bankruptcy of the employer does not justify switching to statistical income data.
Extracted reasoning
The relevant question is what the insured person would probably have earned in the determining year. Statistical data are used only in exceptional situations, such as when the occupation no longer exists on the labor market or the last salary is not a reliable benchmark. The administration is not required to track the economic fate of the former employer.
