Questione giuridica chiave
How should the hypothetical valid income be determined for disability assessment under Art. 16 ATSG?
Decisione estratta
The cantonal court was entitled to base the valid income on the 2008 Swiss Earnings Structure Survey, table T1, requirement level 4, total men.
Motivazione estratta
As a rule, the last earned income is decisive, adjusted for inflation and real wage growth. Departures require proof of greater probability. Here, the claimant had not worked in his trained professions since 1997 for non-medical reasons and had only sporadic low-paid auxiliary work; nothing indicated that he would probably have resumed a better-paid occupation.
