Questione giuridica chiave
Whether the appeal could be entered into despite non-payment of the court advance.
Decisione estratta
No. The advance was neither paid within the original deadline nor within the grace period, and the late legal aid request did not validly preserve the deadline.
Motivazione estratta
Under Art. 62 BGG, failure to pay the advance within the grace period leads to non-entry unless a properly substantiated legal aid request is filed in time; the submitted request was incomplete.
