Questão jurídica principal
Whether the cantonal court unlawfully parallelized the comparison incomes when calculating the invalidity degree.
Decisão extraída
Yes. The cantonal court double-counted invalidity-external factors by parallelizing both the valid and invalid income; the IV office's method was correct.
Fundamentação extraída
Because the insured's valid income had already been derived from a standardized sectoral table wage, the invalid income also had to be based on the comparable private-sector table wage. Otherwise invalidity-external factors would be counted twice.
