Questione giuridica chiave
Whether the appeal must be entered into despite non-payment of the cost advance.
Decisione estratta
No. Because the appellant did not pay the advance within the set deadline, the court declined to hear the appeal.
Motivazione estratta
Under Art. 62(3) BGG, failure to pay the required advance after an unextendable grace period leads to non-entry; the simplified procedure under Art. 108(1)(a) and (2) BGG applies.
