Questione giuridica chiave
Whether the cantonal court exceeded the scope of the federal remand under Art. 66 OG by reassessing valid income and deducting social contributions
Decisione estratta
The remand allowed a full redetermination of the loss of earnings; the cantonal court stayed within the federal mandate and did not worsen the claimant's position.
Motivazione estratta
The remand concerned the entire complex of factual and legal questions on loss of earnings, so the lower court could reassess the income basis and use the net-profit method; only reformatio in peius was barred.
