Questione giuridica chiave
Whether the revision justified retroactive partial withdrawal of the disability pension because the insured's earnings reflected full earning capacity rather than social salary.
Decisione estratta
The record was incomplete and contradictory on whether the wages contained a social salary component; further fact-finding was required.
Motivazione estratta
The Federal Court found inconsistent wage data and no sufficient explanation for the increase in earnings despite an unchanged medical condition. The lower court could not simply rely on the employer report and discard contrary indications.
