Kernrechtsfrage
Whether valid income should be based on the original farmer occupation or the later saddle-maker occupation.
Extrahierter Entscheid
For assessing the insured's invalidity, valid income had to be based on the later occupation as saddle maker/saddle master, not on the original farming profession.
Extrahierte Begründung
The decisive criterion is the activity the person would probably have continued in at the relevant time without disability. Since the insured had worked for years as a saddle maker, had earned a disability-excluding income in that profession, and the agricultural sector had undergone major structural change, continuing farming was not shown as more probable than not.
