Key legal question
Whether the invalidity degree and pension entitlement could be determined without clarifying contradictory employer income statements for the valid income.
Extracted holding
No. The discrepancy between the two employer salary figures had to be clarified before a final pension decision could be made.
Extracted reasoning
The valid income must be established as concretely as possible, normally from the last earned salary adjusted as necessary. Because the two reported figures led to materially different invalidity percentages around the pension threshold, the relevant employer statement had to be verified.
