Questione giuridica chiave
Whether the federal appeal can be entered into despite non-payment of the required advance on costs.
Decisione estratta
No. Because the advance payment was not made within the extended deadline, the appeal could not be considered.
Motivazione estratta
Under Art. 62(3) BGG, failure to pay the advance after a grace period permits non-entry; the matter was therefore disposed of in simplified proceedings under Art. 108(1)(a) and (2) BGG.
