Questione giuridica chiave
Whether the appeal became moot after the AI office withdrew its decision
Decisione estratta
The office validly withdrew the challenged decision under Art. 53(3) LPGA, so the appeal became without object and the case had to be struck off.
Motivazione estratta
Until the authority's submission to the appellate court, the insurer may reconsider the decision. Once the office announced it was withdrawing the premature decision, there was no longer a live dispute.
