Questione giuridica chiave
Whether the invalid income had to be based on the appellant's actual earnings as a crêpière or on statistical wages
Decisione estratta
The invalid income was correctly determined using statistical wages, because the appellant's part-time job did not fully use her remaining work capacity and the conditions for using actual earnings were not met.
Motivazione estratta
Actual earnings may be used only if the employment is particularly stable, fully exploits the residual capacity, and the pay corresponds to the work performed. Here, the 30% job did not exhaust the medically established 50% residual capacity, so the statutory and jurisprudential conditions were absent.
