Questione giuridica chiave
Whether the appeal had to be entered into despite non-payment of the ordered advance on costs within the extended deadline.
Decisione estratta
No. Because the advance on costs was still unpaid after the grace period, the court could not enter into the appeal.
Motivazione estratta
Under Art. 62 para. 3 BGG, failure to pay the advance on costs after being granted an additional deadline leads to non-entry in the simplified procedure under Art. 108 para. 1 lit. a BGG.
