Questione giuridica chiave
Whether the invalidity degree could be determined by a percentage comparison based on the medical assessment.
Decisione estratta
No. The medical assessment did not refer to a specific pre-disability job; therefore the ordinary income comparison method had to be used.
Motivazione estratta
A percentage comparison is only permissible when the comparable earnings cannot be determined precisely and the same earnings basis applies to both valid and invalid income. Here the expert described a range of suitable sedentary, stress-free administrative jobs, so the invalid income had to be estimated using statistical wages.
